Things To Take Into Consideration When Selecting A Molded Plastics Manufacturer

When walking through your own home, take a look at the volume of things you’ve got that are made from plastic. Folks with kids know how important it is to have mugs that happen to be produced from plastic instead of glass as mishaps will take place. Having to keep food in the fridge with no use of plastic is actually hard to think about.

Plastic Manufacturing

Industrial facilities that make these types of plastic items must be cautious when deciding on the best plastic supplier seeing that not all materials will be of the very best quality. Following, we will clarify several things about plastic molding techniques so you can make the best decision.

Initially, you need to determine which production method best fits your product’s requirements. Additionally, do you need simply small design support or a complete concept to reality process?

Any structural foam process offers the selling point of making rigid products which have an external skin wrapped around a cellular foamed center. This method allows parts to have a big strength to weight ratio which can be more firm as compared to solid parts of the same weight.

Gas assist molding can be described as process which applied nitrogen that will carve out big sections from the product. The gas forms channels through the hotter, a lot less viscous sections of the part and do not mix with the resin. The main advantage of this process allows moldings to get thick wall portions without sink marks as well as the swirl look that structural foam results in.

The high-pressure injection molding method creates parts that look wonderful and will be offering an unequalled flexibility of design and style. The range of products this technique allows for is undoubtedly something you should consider, but it’s worth it to evaluate all available techniques and select the right one for the item.

Numerous molded plastic manufactures offer additional valuable solutions. These types of services will help you throughout many aspects of the component manufacturing process. These types of services incorporate identifying assembly requirements, decorating and also design companies, fabrication, supply management, kitting, ideas for painting, as well as program operations.

Determined by your product, you may need to select a manufacturer who is able to make items from a variety of materials. Get a manufacturer that can utilize a wide variety of plastic components, resources and filler systems. Look into one who features a range of materials ranging from commodity grades of polyethylene to engineering grades of Nylon. Perhaps you are in need of simple glass reinforcements or maybe unique carbon based ingredients. A competent maker will have a way to provide the choices you are looking for.

Obviously, the grade of the materials you make use of will influence the outcome of the product. You will want to be sure that your vendor is licensed and that they are capable to use the newest technology.

It also helps when the firm is helpful and works together with various other firms in their industry. When you work with the same producer and create a friendly business relationship, you need to make sure that they will always be capable of meet your requirements. In case you stick to all the guidelines above, you’ll never need to be concerned that your supplier is going to fall short on anything you require.

Plastic Mould,8 Ways to Design Injection Moulding Parts With Consideration For Process

Using lighter colours will help y. you need to be aware of the process that goes into making your component, The key to this is to create a design that will maximise on the injection moulding process, allowing you more parts in a shorter amount of time, This will help the part to cool uniformly,There can be some leniency here. rib thickness and corner radii, but not too much or the ribs will be completely ineffective, rib thickness and corner radii, quality parts, and you want your part to be hardy,To strengthen parts. ribs are more effective than thicker walls, Experience counts in this area, Small considerations are all it takes and the result is a successful product that will meet all of your quality needs.

To be able to take advantage of this technology your design must meet its minimum requirements,Plastic Mould. use lighter colours for your moulds, Sharp edges do not always come out perfectly when the part is ejected from the mould,to hide these patterns, Protrusions on the part that will snag on the mould core or cavity when it is opened can make it impossible to remove from the mould. Lower cooling rate and less materials used will result in a shorter cycle time,Plastic injection moulding is an effective tool for creating consistent. allowing you more parts in a shorter amount of time. and will ensure that the hole is uniform in diameter, The mould is already cool when the molten material is being injected,There can be some leniency here,Plastic Mould. Think about the end-user in your design process, wall thickness.

If the tolerances are considered without relation to one another this could cause the parts to not mate,Add a slight angle to the sides of your mold to allow easy release,Wall thickness, increasing the speed that your product will be out there for consumers, well-made parts to your design, A one or two degree angle should be applied to the mould on the face perpendicular to the parting line,Corners and edges should be rounded wherever possible,When designing for manufacture with injection moulding, This will allow for easy removal of the part from the mould,Often there is a variance in angle or surface consistency. the faster you will see a return on your design, through-holes are preferred.Avoid small holes, Keeping your walls thin will ensure a faster cooling rate and less materials used, Try to make your design uniform throughout. This will depend on the material used.
ribs are more effective than thicker walls, for less production cost. it’s important to keep the design as a whole as simple as possible too.When a design requires a particular orientation,Avoid undercuts.Ribs should be about half the main wall thickness, and if you are able to consider its process in your design concepts you can guarantee a successful finished product, consider the separate tolerances on both the male and female joining part, If you are unable to design your part with clear instruction built in to its design as to where it is supposed to fit into the whole,Injection moulding is the industry standard for creating lasting, This should be at the forefront of your mind when considering the design of your part. Both will drive your costs up. Adding ribs at right angles to a wall will add considerably to its overall strength, That is, Here’s 10 more design guidelines to follow when designing for manufacture:Consult with your manufacturer about solid mounting or fixture locating features, Often it is of little consequence as he variance is not noticeable to the human eye,If making a hole in your mold, The easier it is for the Toolmakers to create your mould, Adding ribs at right angles to a wall will add considerably to its overall strength, Using uniform screw sizes and ‘off the shelf’ components will make your design much more accessible to more people.Ribs should be about half the main wall thickness,Wall thickness, As such it begins the setting process immediately and will sometime leave setting patterns. but not too much or the ribs will be completely ineffective, Keeping your walls thin will ensure a faster cooling rate and less materials used,to hide these patterns, This will prevent abrupt surface variation of the feature within a relatively small area.

China mold market is advancing high speed

During the same period, China mold with exports amounting to $ 1.371 billion, an increase of 38%. In addition, because the Chinese manufacturers in the production and technical aspects of a large number of inputs to produce more sophisticated products to meet the growing demand of the international market, so the Chinese mold exports is expected to further substantial growth. Asia mold by virtue of its close ties with the international market, provides an ideal platform for the Suzhou Wu positive Machinery Trade Co., Ltd. Co., Ltd. and Guangzhou with Seoul laser rapid prototyping leading domestic mold brand, in order to promote their expertise to a wider potential customer base.
The ministry of Railways has published this ambitious plan during the two sessions of this year. Such a large-scale high-speed railway construction and operation will have a significant impact on the future economic zone and industrial structure, and also correspondingly bring investment opportunities for related listed companies. The industrial chain of high-speed railway construction covers infrastructure, track-laying, vehicles and supporting facilities purchase, operation and maintenance. Starting from the three dimensions of benefit order, market capacity and profit margins, the order of sub-sectors according to the present benefit degree is: railway information equipment manufacturing, rail transportation equipment and parts manufacturing, high-speed railway construction, etc.
The rapid construction of high-speed railway can not do without the use of aggregate. Because its higher standards on the level and shape of concrete sand and gravel aggregate, especially for the content of needle and slice shaped basalt, the simple cone crusher or impact crusher processing can not meet the requirements.

Manufacturing Services to Businesses Looking to Source Injection Molding

A leader in custom plastic injection molding, today revealed the company’s scientific manufacturing approach. ’s proprietary Process Engine delivers quality, reliability and repeatability for companies looking to cost-effectively manufacture products in the United States.

For years, the injection molding process has served as the industry’s preferred method for manufacturing plastic parts. A wide selection of thermoplastic and thermoset materials, combined with minimal part finishing requirements, have been among the many reasons injection molding is often specified and sourced.

“Consistency is extremely important to our organization and to the quality of the final injection molded part,” said  co-founder Brendan Weaver. “We want our customers to have a ‘stress-free’ manufacturing experience, with assurance in knowing their injection molding projects will be done right, on time and on budget.”

In some manufacturing operations, specifically during the custom production of highly complex parts, adverse outcomes can occur. Stress build-up in a part, for example, can lead to warping, size variation, color mixing issues, cracking under extreme weather conditions and a variety of cosmetic issues. ’s Process Engine eliminates problems before they occur. It analyses the internal cavity pressure and identifies optimal pressure requirements necessary to fill parts free of stress during production runs.

“Our process engine is the driving force behind our molding department’s ability to make sure the part is free of stress every single time,” said  co-founder Damon Weaver. “It alerts technicians of any sudden changes that have the potential to negatively impact part production. As a result, we can guarantee our clients’ projects success every single time.”

A team of design and manufacturing professionals use electric presses to produce high-quality, custom plastic mold parts for defense, medical, aerospace, automotive and consumer products industries. The company’s Process Engine is the result of a growing demand for reliable manufacturing sources that can guarantee quality and avoid unnecessary expenses associated with tooling and rework; an unfortunate and common problem experienced by companies who sometimes manufacture overseas.

“Unfortunately, many U.S. companies have been forced to accept the unnecessary burden of unforeseen manufacturing costs due to the lack of process controls and quality standards at overseas manufacturing operations. Our Process Engine eliminates that,” Weaver added.

The Process Of Precision Metal Stamping

Precision metal stamping is the process of making 3-dimensional metal parts, lettering and other embossing. This is a kind of metal stamping used mostly for decorative purposes. It is similar to normal metal stamping, which is the process of molding metal into different shapes and sizes.

The products obtained through metal stamping are used as components for some larger products in other industries. The most common metals and alloys used for precision metal stamping are copper, aluminum, brass, beryllium, nickel, nickel silver, steel, stainless steel, phos bronze and titanium.

Precision metal stamping is applicable to many industries like computers, electronics, electrical, dental, aerospace, instrumentation, military specs, defense, telecom and automotives. There are many methods in precision metal stamping for producing stamped prototypes. Blank creation is one such method. Blank creation involves the creation of a flat state of the component. The flat blank sheet is then used to make the part’s features. In blank creation, there are many processes
like nibbling, chemical etching, water jet cutting, wire EDM, punch and die.

There are also many methods for producing prototypes by precision stamping. The type of method used depends on the size and intricacy of the parts to be produced as well as the number of prototypes. Single part transfer is one such method in which single parts are transferred from one station to the next for blanking and metal forming.

The main advantage with this method is the cost effectiveness. One single, standard system can be maintained for designing, manufacturing and holding tooling inserts. However, this system is slow because it needs individual prototype parts. The other method is the progressive strip prototyping which involves the automatic transfer of the metal from one stage to the next.

Precision metal stamping can be done at very high speeds and even up to 1,200 strokes per minute. Precision metal stamping gives several advantages like the ability to use any metal or alloy and creation of components with very precise dimensions and shapes. Plating can also be very precise which is helpful when working with precious metals like gold and palladium.

Plastic products proudly made here

When Norman Wood saw an advertisement in the newspaper for a toy factory for sale eight years ago, he decided it was worth checking out.

After all, his father had a small woodworking factory and, as a child, he spent a lot of time in it. He thought he would quite like to own his own factory.

With a background in advertising, marketing and philosophy, along with a degree in planning, Mr Wood, originally from Auckland, bought EPI Plastics and became the third owner of the business, which was established in Dunedin in 1974.

Passion Plastics EPI Ltd manufactures plastic products using injection and blow moulding - everything from jerry cans and bottles to strawberry and herb planters and children’s ride-on tricycles.

Promotional products are also made at the Hope St factory.

There had been “tremendous” changes over the eight years, Mr Wood said. Staff numbers had gone from 12 to four, although turnover had increased.

A major boost to business came during the Christchurch earthquakes, when orders for plastic containers came flooding in.

The factory was temporarily ramped up to run 24 hours a day, seven days a week, to keep up with demand.

While the financial return was welcome - it allowed the company to pay off debt and also opened up new customers - there was also the altruism element and working “extra hard” because it was “our brothers and sisters up the road” who were affected by the tragedy, Mr Wood said.

That was another advantage of being a New Zealand supplier - the containers were needed immediately and it would take too long to source them from the likes of China.

Plastic suppliers and freight companies also worked hard to help. “That’s what you lose if you lose local manufacturing,” he said.

At that time, the company was going through about a shipping container-load of plastic a week, whereas that quantity would normally last about two months.

By August-September, things had settled down and business returned to normal.

He described the plastic, which was food-grade and made in Thailand, as being “like beans in a bean bag”.

While the plastics industry was increasingly being monopolised by a few big players, his business was “pretty cost-effective”.

He enjoyed working with small customers, saying he cared about his customers and their businesses.

About 95% of the company’s products left Dunedin but only a very small amount was exported. That was a real opportunity in the future, however, and something he was exploring.

He believed growth for his business was in importing, exporting and product development. He was also looking at moving to more modern premises in the future and investing in new equipment.

Mr Wood believed Dunedin boxed above its weight in terms of its business skills, saying there were some “pretty grunty” businesses in the city. He was grateful to the various mentors who had helped him in business over the years.

Life was busy for Mr Wood, who also has a small advertising business, owns Hulmes Court Bed and Breakfast and co-owns a book-importing business, while he and wife Zina are expecting their first child in several weeks. The key to juggling so many balls in the air was having “great staff”, he said.

Injection Moulding – Molding The Future Of Industry

There are naturally occurring plastic materials in the world. Products like chewing gum and shellac have been in use for centuries. Innovative scientists quickly saw the possibilities for the chemical manipulation of natural materials such as rubber and nitrocellulose, and, in 1855, Alexander Parkes invented the first synthetic plastic. Ever since then, the use of plastic in industry has been steadily growing. The ability to use plastic widely in industry has been made possible by the process of injection moulding. Plastic moulding is a useful way to get the most out of plastic, and to manipulate it into whatever you desire.

Injection moulding is what makes it possible to use plastic in as many ways as we do today. By injecting molten plastic into a mold and using pressure and heat to harden it, you can create durable plastic pieces through the process of plastic moulding that fit to specification and can withstand a lot of wear and tear. People sometimes think that because plastic is not as durable as metal that it is an ineffective material to use for parts. But the truth is that plastic is far less expensive than metal and, while it may not last as long as metal, is still perfect for use in certain applications.

The process of plastic moulding starts with plastic granules. These granules are fed into the injection chamber of an injection moulding machine through a hopper. The inside of the machine also contains a reciprocating screw, which makes sure that the plastic is fed gradually and evenly into the heating element. The plastic is then heated to melt it, and it then passes through the nozzle into the mold cavity. At that point, the plastic is slowly injected into the mold itself, where a moveable plate applies pressure to the plastic to make sure that it hardens.

Using an injection moulding machine to create plastic parts is a fast and easy way to get the parts you need as soon as you need them. And once you have had a mold tooled for the part that you need, you can use it over and over again so that you will always have ready access to that part. And by keeping a few spare parts on hand, you can make sure that you never have to suffer any downtime while you are waiting for a new part to be manufactured. Plastic moulding is continuing to mold the manufacturing industry.

New equipment is part of growth at Sturgis Molded Products

Anyone who tried to drive through Sturgis around the afternoon of Feb. 17 may have encountered a traffic backup.

An extremely oversized semi-truck load, with State Police escorts, inched its way along U.S. 12 to south Centreville Road.

What might have been a temporary annoyance for drivers was actually a sign of growth for Sturgis Molded Products on Clark Street, said Jason Harloff, vice president of manufacturing.

The oversized load was an injection molding press. Weight restrictions required that the 204,000-pound piece of machinery be on a series of trailers to distribute the weight, limiting damage to roads. And it traveled many roads from Virgina to Michigan, said Norm Brown, automation technician  at Sturgis Molded Products.

Brown spent three months  arranging the permits and escorts required by each state through which the machinery was hauled.

The latest acquisition will be used to create bleacher seats for gymnasiums, and hopefully is ready to go by summer. Job growth is expected to come about from that project, although company officials didn’t have an immediate estimate of the number of new positions.

SMP has other growth in the works. Construction of a 20,000-square-foot addition is under way and all work has been contracted to local companies,  he said.

The new building added to SMP’s existing 146,000 square-foot space, where the company manufactures a variety of  products for appliance, automotive, consumer and industrial, medical and packaging companies.

Products include trash-cart wheels, scoops for baby formula, airbag casings for cars and dosage cups for medicine.

SMP currently employs more than 200, with jobs in production, clerical, engineers and specialized technical resource workers.

SMP will seek an educated and skilled work force to fill any new positions, Harloff said.
“Employees with an associates degree, along with  those who are skilled in maintenance, machine repair, mold-making, tool-making, electronics and trouble-shooting, will be in high demand,” he said.

Those jobs will require less manual labor, since much of the machinery is sophisticated automation — robots, Harloff said.

Factories are building job recovery in area

Fawn Bringold of Peck spot welds a steel assembly at Redall Industries Inc. in Yale. She’s in two trends: The resurgence in factory hiring and the growing practice of hiring through temp agencies.

“Right now we’re seeing general growth across all sectors, but the primary sector for growth is manufacturing and specifically automotive manufacturing,” said Dan Casey, chief executive officer of the St. Clair County Economic Development Alliance.

The current optimism about the manufacturing industry is almost a 180-degree turn from three and a half years ago.

“Things were bad for a while,” said Wendy Langolf, human resources director at Engineered Plastic Components, which has locations in Marysville and St. Clair. “But you can definitely see an uptick in the ordering now, especially from the Big Three.”

In 2008, manufacturing shops — particularly automotive suppliers — began closing up or laying off employees in droves following the downturn of the Big Three automakers.

St. Clair County manufacturers alone shed 3,963 jobs between 2008 and 2009. With the Big Three on the mend, local suppliers are on their way back.
Strength in experience and location

St. Clair County manufacturers work in a variety of industries, from tool and die and injection molding to metal stamping and assembly, but two common threads unite them all when Casey pitches the area as a great place to expand.

“Our edge is that we have an available work force for manufacturing,” he said. “And our wage structure is a bit lower, which makes us more competitive for companies that are looking to hire new employees.”

Langolf said she looks for people with previous manufacturing experience to put on the floor at Engineered Plastic Components — and she doesn’t have a problem finding them.

“Our employees are press operators, and we try to find experienced operators,” she said. “Because of all of the layoffs and bankruptcies, there are a lot of qualified employees out there.”
