These flame-retardant, durable, self-skinning foams (also referred to as integral-skin foams) are used extensively in aircraft flight decks and cabin applications. The harder, more durable of our flexible polyurethane foams, this tough integral-skin polyurethane foam system can be pigmented and in-mold painted for a lasting finish. WSF-1121 products are used by airframe manufacturers for molded and fabricated flight-deck padding and aircraft interior parts. This self-extinguishing, flexible urethane foam can be custom-molded to your exacting specification.

Molded Parts
General Plastics fabricates and machines custom-molded parts to customer specifications using high-density flexible and semi-flexible polyurethane LAST-A-FOAM® materials. Look to our unique foam formulations and proven built-to-print capabilities to satisfy your most demanding production requirements. Our high-capacity production facilities enable us to scale production to project needs - from a small, short-term run of specialty parts to an extensive, ongoing OEM parts program.

General Plastics Manufacturing Company is ideally qualified and equipped to manage all aspects of a molded-foam part program. As your production partner, our seasoned estimators, CAD/CAM designers, procurement specialists, chemist and production staff will custom-develop your build-to-print program. Our team can support you with part and tool design, mold tooling manufacture, and production of parts through all phases to completion. When necessary, we will also custom-formulate appropriate foam systems to make just the part you need, with all the physical properties and other attributes you require.

Based on your specifications, we'll recommend the optimal solution for density-to-part-weight control, void control, part consistency, surface quality and physical properties. Low scrap rates, competitive tooling costs and our collaborative approach make General Plastics a leader in custom molding services.

In addition, count on us for any accessory items needed to complete your assembly: metal brackets, clips, handles, other hardware, mounting fasteners, etc. We manufacture composite-laminate backing structures to provide support for foam parts if needed. To further streamline processes, we can also manage procurement and incorporate these items into your project if you desire.
