The Linde Group has transformed gas injection moulding (GIM) with a fresh shot of carbon dioxide (CO2).
The technology company revealed the results of its first plastic series production using the innovative PLASTINUM® GIM C system, which uses CO2 instead of the more common alternative nitrogen (N2). The system indicated a significantly improved cooling capacity.
The core of the new process is a CO2 compressor control module for precise pressure regulation and a dedicated injector optimised for CO2. CO2’s higher density, greater thermal capacity and expansion cooling ability during depressurisation compared to N2, allows the manufactured part to cool down much quicker and delivers a higher level of efficiency.
Following a pilot installation at a moulded part manufacturer, this innovative technology had been shown to reduce cycle times by up to 36% and could be the answer to a more proficient plastics production sector.
