Rapid Temperature Cycling Injection Molding

Rapid Temperature Cycling, (also referred to as Rapid Heat Cycle Molding or Vario-thermal Molding) will enable you to heat the surface of the injection mold to 200C.

The technology uses Saturated Steam to heat the injection mold and Tower Water to cool the injection mold. At the end of the cooling cycle Compressed Air is blown through the injection mold cooling channels to remove the water. Steam at up to 235C is then flowed through the cooling channels to heat the surface of the injection mold PRIOR to plastic injection, the steam is subsequently removed by Compressed Air followed by cooling water to remove the heat from the plastic.

The latest generation of Steam Heating equipment has an integrated electric boiler system along with the steam control valves and water cooling pump making the equipment fully mobile and easily moved from injection molding machine to injection molding machine.

Saturated Steam has SIX TIMES the energy of pressurized water at the same temperature, due to the Latent Heat energy in steam, thus heating times are up to 66% faster than a pressurized water system. If you are interested to trial a system please let me know as we have equipment available for trials in China, Europe and the USA.

These type of systems have replaced many of the electrical injection mold heating systems (cartridge heaters) in some of the largest Consumer Electronics suppliers in Asia (Samsung & LG Electronics) due to their robustness and ease of implementation since the mold tool is basically a stand injection mold.

We have been selling this technology since 2007, predominantly to the Consumer Electronics industry (LCD / LED TV frames) but more recently to the Automotive Industry. Our experience is that if the mold tool is manufactured using good tool steels, designed correctly and not over hardened (max 48rC) there should be no problems. In the early days (2007 / 2008) we heard some anecdotal stories of tools showing some signs of fatigue, but this was put down to the use of poor tool steels. There are now hundreds of injection molds running this process successfully around the world.
