New plastics machinery comes with its own controllers, but a number of independent companies will use K'95 to show off their own devices: Gas Injection Ltd. (Hall 1, Stand C22-6) will use K'95 to launch its phased pressure-control equipment for gas-assisted injection molding.
The controller will enablemolders to achieve a higher degree of control of the gas during the initial injection stage and monitor conditions within the mold of key data such as melt pressures and temperatures.
Gas Injection, from the United Kingdom, also will show its sealed injection of gas method of injecting gas into the plastic inside the mold; external gas molding, a way to apply gas pressure to the surface of a molded product instead of conventional internal gas-assist; gas preparation systems including nitrogen generation, pressurization using electric compressors and gas recovery for recycling; and computer-aided-engineering flow analysis of plastic and gas.
R.E.P.S. (Hall 1, Stand D04-8) makes a system that controls mold heating and cooling, taking into account that injection molding is a cyclical process in which temperatures change.
The company's technology makes use of controlled pulses of cooling water and pulses of heat. Induction heaters in the backplate of the mold further modify the temperature.
This is the first time the British firm has exhibited at K.
