One-component mechanically foamed gaskets give non-stop production
Report by Liz White.
Foam-in place gaskets were on offer from several suppliers at the K2010 event, but Japanese producer Braking Sunstar thinks its Penguin one-component polyurethane foams, made at the K show using Ceracon’s robotic dispensing equipment, have stolen a march on the competition.
Sunstar’s mechanically-foamed 1K Penguin material and Foamply applications process give very high productivity – much better than two-part, chemically foamed materials and processes, claimed Steven Hoof, manager of Sunstar’s chemicals business in Europe.
“It’s a very simple process,” he said, explaining that, “This is why we show equipment running, making gaskets. This is why we run it throughout the day, which for our competitors is very difficult.
Two-component foaming technology has been on the market for about 30 years. It makes foam by mixing the components including blowing agent, and creating a gas at atmospheric pressure, Hoof said in a 28 Oct interview during K2010, held 27 Oct- 3 Nov in Dusseldorf, Germany.
Hoof described this chemical process as “very inconsistent,” pointing out that it depends on many environmental issues: “temperature of the part, atmospheric pressure, chemical reaction, temperature of the components.”
As a result, he said, productivity drops to 85% with the other15% needed to services or clean the equipment. “It depends on the operator to…
