Gas Injection Worldwide Ltd. has launched a new generation of RTC (for “rapid temperature cycling”) steam heating technology.
The Winsford, UK-based company launched RTC in 2007, and Raymond Foad, sales director, said the technology has continued to grow into new applications, especially automotive.
“Although we have continued to refine the original system, this new generation of equipment is a quantum improvement, not only in hardware design and functionality, but also with respect to improving the physics of the process,” Foad said.
The new equipment operates on a higher steam temperature than the earlier technology. Customer tests on production tooling have shown the higher temperature can reduce mold heating times by up to 2/3rds over a conventional steam boiler, giving a significant cycle time reduction, according to the company.
Engineers also have integrated the electric boiler with the steam controller to produce a single compact unit that can be moved around a factory.
Gas Injection Worldwide said RTC gives an improved high-gloss surface finish with no weld and flow lines, and up to a 50 percent reduction in mold filling pressures, show part designers can use thinner wall thickness and get lighter parts.
