Liquid Silicone Rubber (LSR) is a non-toxic, soft and semi-transparent material with high temperature resistance and extremely good chemical resistance features. It can be applied in auto parts and healthcare and medical products. With the market demand for LSR parts growing bigger and bigger, there are stringent requirements on the size of the parts and the shape of the finished product is complex. Yet their returns are higher than conventional silicone rubber products.

Although the demand for LSR products is growing by day, the enormous capital investment in direct adoption of overseas LSR technology and the lack of experienced professionals in LSR processing locally have meant there were few local manufacturers of LSR products. This hindered the development of the LSR market for Hong Kong industries.

To address the problems, HKPC and several local machinery manufacturers have jointly developed the LSR Injection Moulding Machine and Over-moulding System to provide a competitive LSR production system and technical support for local industries to explore the high value-adding healthcare and medical product market.

Having acquired the LSR product and mould design know-how, processing techniques and applications, HKPC is now ready to transfer the latest technology and mechanical knowledge on LSR to Hong Kong plastic machinery and plastics product factories and to support their bid to produce high value-adding products.

The LSR Injection Moulding Machine and Over-moulding System jointly developed by HKPC and local industries is expected to cost 25% less than an imported system of the same type.The LSR Injection Moulding Machine and Over-moulding System jointly developed by HKPC and local industries is expected to cost 25% less than an imported system of the same type.
