For more than five decades, EnviroTech Custom Plastic Injection Molders has been delivering the best custom plastic injection molding in the industry for our customers. We take a highly personalized and interactive approach, working closely with you to develop the solutions you need.
We have the ability to take your project from concept to production in-house. This means that every step of the process, from design and engineering to tooling, protype, and full production, is done under the watchful eye of our experienced team. We have the capacity to produce custom molded products of all types, including pump parts, filtration system components, industrial valves, pipe fittings, and more.
Custom Injected Molded Products
We are specialists in conceiving and executing custom solutions for our customers.
Injection-molded product fabrication is a complex and potentially costly process, especially when no off-the-shelf solution will work for your needs. We have worked hard to streamline our processes to ensure that even custom solutions can be delivered quickly and cost-effectively.
When you trust EnviroTech for your custom plastic molding manufacturing needs, you will see what we are the industry-leading expert. Our unique approach ensures that you get what you need when you need it. Our customization abilities far exceed those of our competitors, allowing us to go as far as engineering resins and formulating thermoplastic materials just for you.
Advantages of Custom Injection Molding
When you need a specific part for your manufacturing business that is uncommon or not readily available, you may turn to custom injection molding. Whether you have your engineers design the piece or you use our staff, you can rely on our custom plastic molding company to produce the part you need.
You may think that a short run of a custom injection molding piece would be prohibitively expensive, but our injection molding company specializes in producing custom orders for clients for a reasonable price. Using plastic injection molding provides a variety of benefits besides cost savings, and these include flexibility, consistency, speed, strength and efficiency.
Working with EnviroTech provides additional benefits over working with other custom plastic injection molding manufacturers. Our decades of experience instill confidence in our customers that our processes work — and not just our custom plastic molding processes, but also other functions of a dependable supplier, such as timeliness, pricing and customer service.
Additionally, we provide services you can’t get at every injection molding supplier. These include:
- Near net shape molding
- Slab stock molding
- Filter plate molding
- Industrial molding
- Large part injection molding
- Thick-walled injection molding
- Heavy injection molding
- Filter plate manufacturing
THE PLASTIC INJECTION MOLDING PROCESS
Injection molding is a common way to manufacture plastic parts. Parts manufactured using injection molding vary in size, shape and complexity. Injection molded plastic parts are used in a variety of situations from engine parts to medical equipment. The functionality and use of an injection molded part determines the type of raw plastic material or resin that should be used in the injection process. Plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in the molding process can be complex based on the plastic resin used and part complexity.The process cycle for injection molding varies based on the part size and thickness, times may vary from a few seconds to 30 minutes. Since EnviroTech’s proprietary bulk injection molding processes allows us to mold larger parts, the cycle-time tends to be longer. The main injection molding process steps include clamping the mold shut, injecting the resin into the mold, cooling the molten resin, and ejecting the part.

Frequently Asked Questions (FAQ’s)
Can I choose the type of plastics used in my injection molding products?
Yes, we use almost a dozen different types of polymers to create our injection molding products. Each engineering resin has its own strengths and other benefits, so choosing the best one — or ones — is important. Our engineers make recommendations to you about which plastic to use so that your product has optimal strength and durability.
What is the difference between plastic injection molding and die casting?
Plastic injection molding uses plastic resins, while die casting produces steel products. Sometimes the project you’re working on determines whether you must use plastic or steel parts, but other times either can work. One of the obvious benefits of plastic is that it is lighter weight than steel. It’s also cheaper and it can be produced faster. You get all these benefits along with the assurance that your plastic injection molding products will be accurate and conform explicitly to the design. Plastic injection molding processes also allow for the addition of other, non-plastic products that increase its strength.
Do you do thick-walled injection molding?
Yes, EnviroTech is a leading thick-walled injection molder, successfully producing large runs quickly. We are also known for our large part injection molding and heavy injection molding capabilities. While a benefit of plastic injection molding is the light weight of the product, sometimes a design calls for that product to be heavier, and we can easily meet this need.
