When it comes to low-volume molding – annual pieces numbering as few as 100 – Commercial Plastics has your project requirements covered. Our short-run injection molding capabilities are supported from design through distribution with the same commitment to quality control and customer service as our large-volume molding.

Short-run injection molding at Commercial Plastics complies with the same rigorous time-to-market standards and helps us serve customers in a wide range of industries. We carefully manage our processes to reduce lead times by employing quick changeover tools that reduce setup time and cost. Flexible work cells also minimize handling, which ensures low-volume molding projects remain cost-effective.

Similar to CPC’s high-volume molding, our short-run injection molding projects take advantage of complete in-house engineering and tool-maintenance services. We also offer over-molding, insert molding and secondary operations for low-volume molding.

Commercial Plastics is a leader in Large Part Molding with over 30 years experience and over 16 presses from 900 tons to 2000 tons.  Our Illinois plant was specifically built for large part molding with a custom underground material handling systems with 6 silos able to hold 1 million pounds of raw material.   We optimize material handling, part handling, quality, cosmetics and logistics that large part molding demands.  All of these components help produce the parts that keep your manufacturing projects running on time and to exacting standards.
