Hot runner expert Mastip Technology recently launched its LSR (Liquid Silicone Rubber) moulding solution aiming to cater to the needs of its customer base in automotive, medical and consumer electronics segments.
Many LSR mould makers and moulders are facing challenges in achieving a uniform cooling profile from the moulding machine to the mould in a repeatable process. Mastip adresses these issues with its new Aquilo LSR Technology.
The LSR solution features a “Cold Deck” design that includes cooling channels in the mould 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. As excessive flashing and material curing in the gate can cause defects in the moulded part and reduce its quality, the use of Mastip's LSR cold deck will result in improved part quality and reduced waste.
Mastip's CR04 and CR06 dedicated LSR nozzles are designed with cooling channels extending towards the valve gate nut ensuring a consistent thermal profile along the nozzle. This design enables optimal control of the valve gate nut temperature which 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.
Mastip's global network gives mould makers/molders easy access to Mastip’s technical consultation and responsive customer support. With its LSR technology, Mastip solve challenges in uniform cooling for a repeatable and shorter production cycle, ultimately delivering higher-quality products to customers in various industries.
