Injection Molding Technology Features Short, Repeatable Production Cycles

Global hot runner company Mastip unveils its recently launched liquid silicone rubber (LSR) molding solution at K Show 2022, aiming to cater to the needs of its large customer base in automotive, medical and consumer electronics segments.

LSR molding uses the process of injecting liquid silicone material mixed with a catalyst into a mold which is heated, accelerating the mold’s curing cycle. LSR injection molding has been adopted in a variety of applications as a result of silicone rubber’s unique mechanical and chemical properties such as flexibility, heat resistance and tensile strength, according to the company. For example, LSR is an ideal material for products with specific sealing requirements such as car key housings, gaskets in automotive, respirator masks in medical devices and electronic wearables.

With over 30 years’ experience in the injection molding industry, Mastip says it has extended its expertise from hot runners and the requirements of exact thermal profiles towards LSR molding technology to help its customers achieve shorter production cycles and higher product quality. Featuring a “Cold Deck” design, the mold plates, manifold and nozzles are fitted with cooling channels to ensure the mixed material is kept in its uncured condition as long as possible until it enters the heated cavity plates. Valve gates also enable optimal control over the injection cycle, while ensuring the flow channels and gate is free of cured material for what Mastip contends is a  perfect shot cycle to cycle.

Mastip delivers its solutions to over 40 countries via its subsidiaries and global distribution partners. The global network provides molders with easy access to Mastip’s technical expertise and responsive product support for the lifetime of the project.

The K Show runs October 19-26, 2022 in Düsseldorf, Germany.
