New “spray-skin” equipment makes cushioning products for medical and outdoor applications with a solid, durable, waterproof skin bonded to an inner layer of foam. Because it produces a better product while reducing processing steps and cost, this spray-in-mold approach can replace integral-skin foams and injection molded, thermoformed, or slush molded skins for items such as tractor, marine, and heavy equipment seating. Spray-skin equipment from Isotherm AG of Switzerland is now available in North America from Linden Industries, Cuyahoga Falls, Ohio.
Isotherm’s spray head and low-throughput equipment is said to spray highly uniform skins as thin as 0.3 to 0.4 mm that perfectly replicate mold-surface texture. Isotherm’s PSM 3000 machine can be used with robotic spraying and its PSM 700 controller and SP 300 gun for hand spraying.
