Our company is known around the world as the industry leader in thick-walled injection molding. We have one of the largest shot capacities in the industry, allowing us to produce exceptional quality thick wall molding components that are void-free. We also design, engineer and manufacture large shot and thick-walled molds.

We started marketing our services to companies that didn’t need millions of parts, but rather, thousands of parts due to exploring new products or a new market! We found that the quality of the tooling that we were making out of aluminum coupled with the way we processed the molds to account for soft tooling, was allowing us to guarantee our molds for not a few thousand parts but for more around 100 thousand parts over the life of the tool.  I am not only talking about molding ABS and guaranteeing 100 thousand parts, but also molding glass filled materials and guaranteeing the same. We have tools that we still use from the 80’s that have run 1 million parts.

On the contrary, aluminum is a great material to build prototype tooling from because it is easy to machine, light, and has an ability to dissipate heat very quickly to keep cooling times low. Also, as stated in a previous blog, if you have to make a modification it can be done very inexpensively.

We have assembled a substantial collection of state-of-the-art equipment at our in-house design and production facility. Using cutting-edge technology and a half-century of experience, we have the ability to produce extremely large, heavy and thick-walled injection molded components.

EnviroTech’s unique proprietary bulk injection molding process allows EnviroTech to manufacture and produce large thick-walled polymer components that are simply impossible for other injection molders.

Our strict and exacting quality control processes allow us to provide consistently high-quality results without sacrificing time or economy. With our ability to customize injection molding solutions for our customers, you get the results you demand, time after time.

As the leading large part injection molder in the United States, EnviroTech designs, engineers and produces large injection-molded polymer resin components. Our streamlined processes and in-house production facility allow us to complete massive production runs quickly and affordably.

Our expansive facility operates around the clock to meet our customers’ needs. And, although we consistently meet the needs of our clients, we always strive to exceed their expectations.

As some of you know, Wepco plastics was opened in the early 1980’s as a prototype injection mold builder. You see, in the 80’s, 3D printers did not exist, so if you wanted a prototype you had to build a prototype mold, even if you only needed 10 pieces to test out. Seems wasteful, and it was… but through continuous improvement, a better way was found.

At EnviroTech Custom Injection Molders, we assist our customers with anything from the most diminutive part to the largest injection molded components. But, when working on substantial components – heavy, thick-walled or especially large – we have capabilities that you may not find elsewhere in the industry.

Wepco has been building prototype aluminum tooling since the 80s, and we found during that time that it would be easier to sample the molds if we had a molding machine, so we purchased our first Arburg all-arounder. We started sampling tools which made it much easier to get the parts to the customer very quickly, which is now defined for us as 3 weeks or less, without worrying about using an outside source. Before long, our customers started to order production runs on the “prototype” tools that we were building. We quickly realized that our “prototype” tools that were supposed to just run a handful of parts then get discarded for a steel tool, were lasting way beyond what the expectation was. We had found our niche!

When you need the best heavy, large or thick wall molding services, call on the experts at EnviroTech for all your bulk and custom injection molding needs.

Our technology and sophisticated automation capabilities allow us to complete even the most massive thick wall molding production runs quickly without compromising quality output. Even complex components are no match for our experience and capability.

Using thermoplastics and polymer resins, EnviroTech has the ability to manufacture substantial components that have all the benefits of polymer injection molded parts – reduced cost, quick turnaround, minimal environmental impact – as well as the desired weight.

We offer a wide variety of polymer and engineering resin materials for you to choose from. We can recommend the best materials for your needs or, if necessary, we can work with our engineering resin manufacturing partners to design a material formulation just for you.

EnviroTech has over 50 years of experience and expertise in the injection molding space, optimizing part design for mold-ability and polymer resin engineering. With presses ranging from 850 – 2500 tons, and our experienced process control techniques that give us the ability to mold virtually any thermoplastic polymer resin and additive composition (see Polymer Resin Section), that opens the door to products for metal replacement and a wide range of industrial applications that were never before believed possible.

Heavy injection molding uses a variety of space-age materials and additives to achieve the weight you need. Our processes ensure timely production and exacting standards of quality as well as the affordability you enjoy with standard injection molded products.

We assist customers across virtually every sector and industry, including defense, mining, energy, oil and gas, agriculture, automotive, and deep-sea drilling rigs. We specialize in mold design, polymer resin engineering, mold optimization and troubleshooting, and custom injection molding of all types.

When people think of plastic injection molding, it is common that they think of mass production and millions of parts produced per year off of extremely complicated, expensive steel production tools. Although this might be a common perception of injection molding, it’s not all the art has to offer. Time to break some common thought:

You want to be looking for a mold builder that understands aluminum molds and how to properly maintain them for optimum life. If you need millions of parts a year, the aluminum option is probably not the right choice for you. But, if you have a product that only requires 10 thousand parts per year, or 3,000 parts per year, or 20 parts per year, and need them to have the quality and strength of a quality injection molded part, then short run production in an aluminum mold is a great choice for you. The viability of the aluminum mold speaks for itself, as Wepco Plastics has been running them for over 30 years, so if you need 20 parts or 250 thousand parts, aluminum tooling has you covered. Being cost efficient and receiving excellent value… the full package!
