Injection Mold Making

Injection mold making is at the heart of what we do at MPP. It's where we got our start, it's how we made our name, and it's what we do best. We have been making custom injection molds for 30 years, with a combined century of mold building expertise. Along with experience, we have a reputation for tackling tough assignments and getting them done on time and on budget. We are pioneers in the creation of two-shot molds, having developed some of the very first two-shot molds in the industry back when everyone else thought it was impossible. 

Our mold makers create custom molds for all kinds of industries — automotive, medical, agricultural, and others. Our master craftsmen are backed by the latest technology, equipment, and training, which we invest in significantly each year. Learn more about our customized injection mold making services.

Injection Mold Preventive Maintenance & Repair

As expert injection mold makers, we are highly skilled at preventive maintenance and repair.  Let's face it. Molds take a daily pounding. It's natural and inevitable that the wear-and-tear eventually takes its toll, necessitating regular maintenance to keep production going or, in the worst cases, to fix molds that have stopped functioning. Our team handles it all. For preventive maintenance, we do full mold teardowns and cleaning. For repairs, we restore your mold to its original print tolerances. From sheared ejector pins to crashed core pins to seized slides, we fix it all. 

When maintenance or repair is needed, our in-house delivery service retrieves the mold from your location, then we return it to you, often within a matter of days or hours. Learn more about our preventive maintenance and repair solutions.

Prototype Injection Molding

We specialize in rapid prototype injection molding for a wide range of industries and applications. Our expertise in manufacturability and materials allows us to create prototype molds that are suitable for real-world use. Prototyping offers numerous benefits. By receiving interactive design feedback for manufacturability, you can make early adjustments before prototyping begins. You can also work with our design engineers to address any design challenges and manufacturing questions that arise.

With our prototyping process, you can have physical prototypes in hand within days, making it easy to modify designs during early product development. We can also produce multiple prototypes simultaneously, allowing you to compare and iterate designs more efficiently. Learn more about our prototype injection molding solutions.

In-House Engineering & Design

All good molds begin with a well-engineered design. At MPP, our in-house designers combine an understanding of manufacturing, machine controls, metallurgy, and plastics to develop mold designs for parts. Our suggestions and recommendations have helped clients save thousands of dollars and hours. From full mold design to engineering changes to updates resulting from product changes, we do it all. And we provide fast turnaround. In some cases, minor engineering changes can be completed in a matter of hours.

There's nothing that we can't engineer. Our experienced designers tackle the toughest assignments, from two-shot molds to two-stage slides and everything in between, delivering the high quality our customers have come to expect, recognize and appreciate.

Injection Mold Laser Welding

Laser Welding

MPP is one of the few injection mold shops to perform in-house laser welding. From our perspective, in-house welding is just as important as machine building. Building a new mold to replace a damaged one can shut down production for weeks. Laser welding can reduce the downtime from weeks to days. Whereas other shops might have a single welder, we have three full-time professionals with many years of experience in MIG and TIG laser welding. Having three welders means we are able to start on jobs quickly to provide a fast turnaround for our clients. 

Worried about the appearance of your repaired mold? Don't. Our welders and finishers are so detail-oriented you will not even know a weld has been made. Our welds are clean and smooth, and our paint team produces flawless finishes.  Learn more about our laser welding solutions.

Injection Mold Pick Up and Delivery

Pick Up and Delivery

What happens when one of your molds needs maintenance or repair and it needs to be sent out for service? Who transports it?

Even a small mold can weigh several tons. Shipping something that heavy can cost thousands of dollars and take several days to schedule via a third-party transporter. Luckily for MPP customers, we have our own pick up and delivery service to save you the time, hassle and cost.

We transport molds up to 18,000 pounds. Our fleet of vehicles can retrieve your mold from anywhere, any time of day or night. We have no distance limitations. We have traveled to Texas, Missouri, Arkansas, Georgia, Pennsylvania, and Ohio to retrieve molds and then delivered them back when finished. Contact our team today.
