MPP Specializes in Plastic Injection Molds and Parts

Our expertise includes but is not limited to single-shot, two-shot, co-injection and insert molds.

Products - Two-Shot Plastic Molds

Two-Shot Plastic Molds

Two-shot injection molds allow you to make parts using two different plastic resins. Two-shot plastic injection molding eliminates post-molding assembly, reduces the number of plastic molds that are needed, and reduces part handling by operators. We are pioneers in two-shot molds, having built some of the first two-shot molds in the industry 30 years ago. 


Single-Shot Plastic Molds

Single-shot molds are the workhorse of the plastic injection industry. At MPP, we've created thousands of single-shot plastic molds for a wide variety of parts and industries. We deliver on-time and on-budget. Our engineering experience and mold building knowledge ensures that your mold will perform flawlessly the first time and every time.

Product - Prototype molds

Prototype Molds

We are a leader in rapid prototype injection molding for all types of industries and applications. Our expertise in manufacturability and materials allows us to produce molds that will work in the real world. Whether you’re an entrepreneur with a bold idea or an established firm testing a new product, make MPP your rapid prototype choice.


Prototype Parts

Need a prototype part to test a concept? Have a finished design that needs real world testing? We can help with prototype parts. We can make them from production molds or using 3D printing. We provide fast turnaround. Developing a prototype part can help avoid common mistakes before production, such as surface defects, bad wall thickness, gate issues, and more.

Plastic Mold Production Parts

Production Parts

At MPP, we can produce low to mid-volume single-shot parts. Our mold-making and plastics knowledge can be a benefit if you need a short run of superior-quality parts. We produce parts for automotive and other applications in our facility, adhering to the same high standards as with all of our work. If you need a low to mid-volume run of parts, let us help.


Two-Shot Parts

Need a supply of multi-colored or multi-materials plastic parts? Our in-house two-shot part production is the answer. Using our knowledge of two-shot molds and our experience in manufacturing, machining and plastic resins, we can help you produce high-quality parts for your production needs. We've satisfied dozens of clients this way.
