Low volume plastic injection molding is driven by customers that have a continuous product development cycle or lower product demand.  Midwest Mold works with product developers, OEMs and tier suppliers to supply plastic injection molded parts for demanding specifications, timelines and budgets.

Compared to plastic injection molding, rotational molding is a relatively low-pressure process. Consequently, rotational molds can use less expensive materials like cast aluminum and sheet metal instead of hardened steel. Rotational molds don’t need coring or cooling, and the molding process doesn’t require secondary tooling either. Because of its low tooling costs, rotational molding is cost-effective both for prototyping and production.

Midwest Mold isn’t like other Prototype/Low Volume facilities. We have the experience and equipment to provide unparalleled speed, flexibility and support. We use our exceptional molding expertise to provide comprehensive technical guidance and tooling options for your project. We don’t just send a price estimate for a new project; we send an informed quote after learning about your needs. We pride ourselves on working closely with you from the start, making sure job specifications align with your project goals.

We encourage prospective customers to bring their next plastic development project to Midwest Mold to experience what our team has to offer firsthand!

While many injection molding companies are starting to put much more emphasis on aluminum injection molds and tooling for its advantages over steel, Midwest Mold has been specializing in it for decades.

Low volume molding projects typically require less than 10,000 pieces per year and Midwest Mold has 100 ton, 165 ton and 330 ton plastic injection molding machines in-house and the ability to go larger as needed.

If you have the “cant wait” mentality and are looking for physical examples of your plastic part ASAP, consider Midwest Mold for your rapid prototyping and prototype injection mold partner. We have 3D printing capabilities and can create and ship your product quickly and easily. Confused about what’s the best process for you? Take a look at our case study that compares 3D Printing vs. Low Volume Production to see which one suits your project best.

Finally, rotational molding can produce strong plastic products. For example, metal inserts can be molded in for integral supports. Rotomolding also supports the creation of ribs, and rotomolded parts can have thicker outer corners than injection-molded ones. In addition, rotational molding can produce plastic products, such as tanks and bins, with a sturdy double-wall construction. Rotomolding even enables designers to replace heavier and more expensive metal parts with lighter and less expensive plastic ones.

Our ideal customer for low volume molding places a high value on supplier relationships, understands price is one element of total cost and utilizes Midwest Mold as their preferred partner in plastic product development to solve problems, propose solutions and share best practices in tool design and optimized processing for shot to shot repeatability.

Rotomolding produces plastic parts and products with excellent surface details, including color, texture, and finish. Compared to other plastics manufacturing processes, rotational molding can also maintain a more consistently uniform wall thickness and part weight. In addition, rotomolded parts are virtually stress-free. Because it’s a relatively low-pressure process, rotational molding minimizes cross-sectional deformation, which can result in defects like warpage.

As a third-generation, family-owned business, our American-owned company stakes its reputation on a commitment to quality, customer service, and continuous improvement.

We’re also proud of our speed, providing short turnaround on injection molding services without sacrificing quality or precision. We’re constantly refining our production process, implementing new ways to reduce inefficiencies and shorten lead times for our customers. Whether you’re looking for short run production, rapid tooling or prototyping services we can help you find the best solution and deliver it quickly and efficiently.

Rotational molding is a plastics manufacturing process that can produce hollow parts in various sizes, colors, and textures. It also supports features, such as tapers and undercuts, which can be difficult to injection mold. Rotomolding offers part designers many advantages, but its low tooling costs, part quality, and part strength are especially attractive.
