Precision Thermoforming of a Plastic Air Conditioner Cover for a Mass Transit Application

Penz Products has many years’ experience thermoforming durable plastic components that stand up to outdoor use while maintaining their like-new appearance. The resilient plastic cover pictured here is used to cover both the front and rear air conditioners located on top of a transit vehicle. We chose a thermoplastic polyolefin (TPO) material that would provide a high gloss, smooth finish which would not degrade from UV exposure. Well-executed tooling and our large format rotary thermoformer enabled us to run high volume production of these 51” x 105” x 5” parts while maintaining the outsized dimensions consistently and repeatadly. We drill and trim the formed parts using our precision 5-axis CNC, all the while maintaining a tolerance of ±.010” on all features and dimensions.

Quality is important to us and the stringent procedures in our ISO 9001:2008 certified quality program ensured that this product was on specification and would remain wear-resistant and cosmetically appealing over an extended service life.
