Molded Window Trim Seals – Seamless, Durable, and High-Quality

Molding is the preferred manufacturing method when part size allows it. Molded window trim seals offer several advantages:

  • No seams or joints
  • Superior cosmetic appearance
  • Consistent, high-strength geometry

Window Trim Seals Made In-House Tooling for Faster Lead Times & Lower Costs


All tooling for window trim seals is manufactured in-house in our CNC machine shop, equipped with 38 CNC machines. This allows us to offer:

  • Faster development and prototyping
  • Lower tooling costs for customers
  • Tight quality control from start to finish

  • We commonly manufacture seals using silicone and EPDM, materials known for excellent environmental resistance. Our proprietary compounds are formulated to withstand long-term exposure to sunlight, ozone, heat, cold, and harsh outdoor conditions—ensuring the seals won't degrade, discolor, or fail over time.

  • Our automated molding equipment includes vacuum-assisted systems and multi-plate separation to efficiently demold complex geometries, including seals with undercuts. With presses up to 8 ft x 6 ft, we can produce large, seamless window trim seals and use multiple platens for efficient manufacturing of oversized parts.

  • We operate four extrusion lines capable of processing organic rubbers (EPDM, NBR, FKM, SBR, and more) as well as silicone, providing ample capacity to support high-volume production. Our semi-automated splicing presses allow us to join extruded segments quickly and accurately, creating a strong, uniform, and reliable trim seal.
