Cast-In Platen Heaters

durex cast-in platen heatersDurex designs and manufactures custom cast-in platen heaters. Platen heaters are a versatile cast-in design that can be adapted to a myriad of applications. Typical uses are heat transfer presses, foodservice equipment, die heaters, packaging equipment, and commercial pre-heaters.

Design Features

  • Aluminum or bronze cast alloys
  • Custom machined surfaces
  • Surface coatings of electroless nickel, Teflon®, or anodized
  • Liquid cooling option
  • Flexible electrical terminations
  • Single or three-phase electrical circuits
  • Custom mounting options

Manufactured from aluminum or bronze alloys, the platen heater consists of a tubular heating element that is designed and formed to provide maximum efficiency and temperature uniformity on the working surface of the casting. The platens can also be designed with integral cooling tubes or as stand-alone cooling platens for chilling applications. The working surface of the platen heater can be supplied with various machined finishes to customer specifications. Durex can also provide a ground surface for stringent flat surface requirements. In addition, surface coatings of electroless nickel, Teflon®, and hard-coat anodizing can be applied per application requirements.

Mounting options can be cast in the design of the platen or machined as a secondary process. These options include threaded stand-offs, cast-in anchors, ribbed back supports, tapped holes, and mounting slots. Electrical terminations can be threaded terminals, flexible wire, three-prong electrical plugs, or NEMA housings. Durex manufactures all platen designs to customer specification. Engineering assistance is available to help create a new design or modify your existing one using our FEA analysis profiles and rapid prototype simulations.
