Custom Extrusion

Custom Extrusion

Utilizing the skills of our highly trained and experienced personnel we work with our customers to understand their needs. In close contact with engineering, quality and design technicians we are able to transform those needs into a customer-defined and approved specification that follows each job throughout the production process.  Samples of the desired product are provided before implementing a full production run.

MPP has been providing, thin walled, small diameter tubing since 1977. Along the way, we have grown and expanded our capabilities. We have a long history with many of our customers, and continually strive to improve our manufacturing equipment and facility with new technology. We have earned our reputation as a world-class provider of close tolerance extruded tubing.

While most of our experience has been with polypropylene, polyethylene (low and high density), propionate, polystyrene, acetate, and pebax, our engineers and production staff will work closely with our customers to develop the product that meets their needs. We also provide co-extruded tubing, and many value-added services.

Coiled Tubing

Working closely with a customer, we developed a method to provide coiled tubing without the traditional method of using a spool and winder. MPP developed a special packaging system that eliminates the problems of diameter fluctuations, kinks and tension caused by conventional winders. This is just one example of the creative thinking and adaptability we bring to each project.

Cut to Length Tubing

Extruded tubes can be cut to customer specifications for any of your application requirements and oriented in rows.


Whether, cut to length, bent or coiled, our products are packaged to your requirements. Our unique packaging process eliminates the need for labor-intensive, in-house counting. At MPP whether your product is bagged, banded or boxed, it is an automated high speed one-step process. You receive precise, actual count to your specific packaging requirements every time. Exposure to dust and other contaminants is virtually eliminated.
