HOW & WHY IT WORKS. X-melt is expansion molding. It relies on the inherent compressibility of plastic melts and uncured LSR. In essence, the procedure is to first accumulate the shot volume in front of the screw and then move the injection screw to its final forward injection position while the material is held in place by cold-runner (hot-runner for thermoplastics) valve-gate nozzles.

The liquid injection molding (LIM) manufacturing process molds silicone rubber into a broad array of parts and products. While the traditional reaction injection molding (RIM) process focuses on a pressurized impingement mixing process, Liquid Injection Molding is comprised of a mechanical mixing method that blends a two-component compound together in a mold.
