LSR Cold Deck Features Valve Gates

Mastip Inc. introduces latest updates to its Aquilo liquid silicone rubber (LSR) systems and looks forward to sharing its experiences with recently completed projects for the medical industry.

Mastip’s LSR solution features a “cold deck” design that includes cooling channels in the mold plates, manifolds and nozzles. This design ensures the mixed material remains in its uncured condition before entering the heated cavity plates.

Additionally, the use of valve gating technology improves balance between cavities and from shot to shot, eliminating material curing in the gate between cycles. Sequential timing of the valve gates is the key component that ensures cavities are kept balanced.

Mastip’s dedicated CR04 and CR06 LSR nozzles are designed with cooling channels extending toward the valve gate nut, ensuring a consistent thermal profile along the nozzle. This design enables optimal control of the valve gate nut temperature which Mastip says is critical in consistently producing high-quality LSR parts.

The consistent thermal profile along the nozzle also ensures that LSR flows smoothly and uniformly into the part, resulting in a high-quality gate and improved part quality overall. This is especially important in industries where precision and quality are critical, such as medical device manufacturing.
