Mad cow inspires bovine-free PVC film
Spurred by European concerns over mad cow disease, extruder Ellay Inc. has developed a bovine-free PVC film that does not use any animal products, such as fatty-acid lubricants.
Commerce, Calif.-based Ellay introduced the film, which uses vegetable-based fatty acids as a substitute for the tallow from cow fat and bones that traditionally have been used to make fatty acids, said Bob Elcik, Ellay technical director. The film is aimed at products for containing blood, such as plasma bags.
The fatty acids are used as lubricants to keep the plastic flowing smoothly through processing machines and as a way to keep the molecules within the PVC moving smoothly, Elcik said. The vegetable-based fatty acids do not sacrifice quality and are about the same price as animal-based acids, he said.
Tubing producer HV triples plant space
Polyimide and composite tubing maker HV Technologies Inc. has moved into a new, 35,000-square-foot plant that tripled the firm's space, giving it room to grow its niche tubing business.
Officials with the Trenton, Ga.-based company declined to disclose expansion costs or production capabilities. However, HV built its own equipment for the layering process used to make the tubing, according to Chief Executive Officer Rudolph Carlson. The company specializes in high-margin specialty tubing, and much of its growth is coming in composites, he said.
Tubing diameters range from one-fifth of an inch down to several-thousandths of an inch — or smaller than a human hair, Carlson said. The new plant replaces previous facilities in Trenton.
Microspec extruder to do wire coating
Microspec Corp. has added a fourth extrusion line, and plans to use it for a proprietary wire coating process for which the firm has a patent pending, said President Timothy Steele.
The line was added earlier this year at Microspec's Jaffrey, N.H., plant. The company would not provide further details.
Microspec's process for coating guide wires makes the coatings apply to a uniform depth even if the wire is not of a constant depth, Steele said.
Crescent invests in new site, equipment
Crescent Industries Inc. has added four injection molding machines and taken over a 100,000-square-foot plant in the past year, doubling space and giving it a total of 16 machines.
The expansion also let the New Freedom, Pa., mold maker and molder put its presses into a better clean room, said Timothy Trimble, a manufacturers' representative with the firm.
Both plants are in New Freedom. About 65 percent of the firm's business is in medical molding.
