Cold Runner Direct Silicone Injection
Silicone is one of the world’s most versatile and useful materials, and not a day will go by in the life of most people that they do not come into contact with silicone in some form or another. 

Silicones are used across a huge range of applications, including aviation and aerospace, transportation, construction, personal and health care, electronics, rubber, adhesives and sealants, paints and coatings, textiles and leathers – and that is just the tip of the iceberg. 

Liquid silicone has become one of the most popular forms of the material, as it is especially suited for applications that require clarity, chemical resistance, and other beneficial properties that do not change over a wide range of temperatures. 

But one of the challenges of using liquid silicone has been the inability to overcome wastage when making small parts using injection-molding processes. 

Sydney company Romar Engineering has come up with a solution to this limitation – a highly accurate silicone injecting and dispensing system that can be adapted for use in parts as small as 3mm. 

Another major feature of the application is the development of nanotechnology which allows the addition of secondary products to the silicone. Potential applications for this could include silicone-shaped pine nuts with poison filler to control possum populations in New Zealand, or nanoparticles of Teflon included in silicone parts such as o-rings to reduce surface friction. 

Romar’s managing director Neil Wilson said the technology offered significant cost savings in waste and materials, and the multi-nozzle system could also replace a number of conventional machines. 

He said the system would be particularly suited to the medical, computer, watch, veterinarian and automotive industries, but could be adapted for almost any use. 

“The same system can be applied to larger components, meaning manufacturers can cut down on the number of machines they need,” he said. 

“Our operation permits us to do high volume as well as short runs efficiently and without sacrificing quality. We believe there is nothing like this.”
