Large Tonnage Injection Molding of Bumpers for the Automotive Industry

Injection Molding of a Bumper
Injection Molding of a Bumper

As a leader in injection molding, MRC has supplied some of the most in-demand and advanced processes in the industry. The project highlighted here involved injection molding of bumpers which provide an appealing and clean finished look to a car. The oversized part required the use of our large tonnage injection molding capabilities, and a trained staff was also able to perform the priming, punching, heat staking, and packaging of the finished part. Advanced 2450 to 3000 ton injection molding presses were used to manufacture it from TPU/TPO plastic with thicknesses from 0.05" to 0.10". The finished part featured dimensions of 80" in length and 45" in width. It was also primed for Class A top coat. Some bumpers are molded in color for a class A finish and include RPA sensor attachments. All work was done to customer specifications with part weights tracked throughout. The project represents a total run of 55,000 units per year.
