Plastic Injection Molding

PMB Inc. is a custom plastic injection molding company offering services for many different customers in a variety of industries. We are locally owned and operated and provide low-cost, high-quality injection molding services, with a quick turnaround. We work with a variety of customers who have either high volume requirements that need daily or weekly shipments to low volume parts that need monthly, quarterly, or even annual shipments.

High Volume

When production requires a high volume of parts every day, we have the ability to build molds and produce parts from multi-cavity molds (4 to 64 cavity) that best fit your needs, all while considering the number of parts needed, part geometry and complexity, plastic material specifications and press tonnage requirements. High Quality Tooling (Tooling Link) is manufactured for these applications to ensure a long-life span of the tool along with maintaining high quality plastic products, for the life of the project. Quality Matters, and because of this not all molds are built the same. We manufacture several different types of injection molds based on your production needs and part requirements.

Low Volume

When you are looking for low volume services like prototyping or new product startups, we offer many options. One example would be building a single cavity prototype mold, for development and testing. These molds can be built from Aluminum or pre-hard steel, and may utilize hand load cavity inserts where a side action is needed. When a new product is starting up it may be beneficial to build a lower cost two cavity mold, or even a one cavity pull ahead until a high production mold is needed.

Transfer Tools

Are you having quality or delivery issues with your current parts supplier, or have you outgrown their capabilities? Transferring your mold(s) to a supplier that can meet your needs is the answer. PMB has a streamlined mold transfer process that is designed to reduce the down time of your mold to as little as 8 hours! Give us a call today and ask to speak with our Production Manager Tony DePriest (ext. 102) or Tom Roth (ext. 106) who is the current Owner/President. Here at PMB we know that you need your parts on time, in perfect condition, every time…without exception!

Insert Molding

Some of the benefits of plastic injected products include cost reductions, weight reductions, and being more ergonomic. Insert molding is the go-to solution when plastic parts need additional strength or wear resistance in a specific area. This application can be used for threaded and stamped inserts, bushings, and pins. PMB can utilize integrated robotics to further reduce the cost of your insert molding needs.

Surface Finishes

We provide a large range of surface finishes in order to meet your part specifications. We run a number of molds with a high gloss polished cavity, which produce plastic parts with a mirror finish. Some customers want a textured surface on their plastic parts, and this can be done by adding a pattern (texture or grain) to the mold cavity surface. We also offer custom engraving (example: your logo), artwork, and other wording as needed.


Finding the right material for your product can get confusing, so we assist with selection. We have experience with a wide variety of materials including, but not limited to:

  • Acetal (Filled and Unfilled)
  • High Impact Polystyrene (HIPS)
  • Nylon (6 and 6/6, Filled and Unfilled)
  • Polycarbonate
  • Polyethylene (HDPE & LDPE)
  • Polypropylene (Filled and Unfilled)
  • Thermoplastic Elastomers (TPE) & Thermoplastic Vulcanizates (TPV)

We have the capability to run clear plastics and a large variety of colors. We can also do a custom color match to meet your exact needs.
