Invented by TROCELLEN

The twinsheet thermoforming process using cross-linked PO foam was developed by TROCELLEN and has proven itself as a technically and commercially attractive alternative to the conventional blow molding process for the production of air ducts.

TROCELLEN’s distinguished know-how and in-depth customer support regarding optimal material choice and process parameters in combination with the company’s perfectly suited cross-linked PO foams have made TROCELLEN the preferred partner for manufacturers of serial twinsheet air ducts as well as car manufacturers.

Air duct

Advantages

Due to the properties of the closed cell PO foam, the air ducts show excellent advantages compared to blow molded ducts:

  • Weight reduction – up to 65% lighter than solid air ducts
  • Thermal insulation improvement – reduction of energy loss
  • Acoustic absorption – up to 5dB less airflow noise
  • Easy assembly – high flexibility, good restoring behaviour
  • Sealing function – no squeak & rattle
  • No condensation – no bacteria
  • Easy prototyping – cost-efficient prototype tools and fast prototype production
