While most blow molders count on flaming to eliminate parting line flash from air intake resonator components, Regency’s blow molding motto is “no flaming”. By design, Regency produces high quality tooling with less than .05mm clearance tolerances for all pinch line interfaces and maintains those tolerances for the life of the program.

Blow Molded Air Intake Tuners

Whether your project specifications call for Class A or Grained Surface finished air intake tuners, we can help develop and minimize the parting line on those surfaces.

Air Intake Resonator & Air Intake Tuners Material Selection

There are dozens of performance factors to consider when determining which material to use for your air intake resonator assembly. Identifying the ideal combination for your application can be difficult to determine. Not to worry, Regency is here to help.
