The following items were gathered by Plastics News senior reporter Bill Bregar at Plastics Encounter Atlanta, held Nov. 13-15.
Canada's Deltaplast signs with U.S. rep
Deltaplast Machinery Ltd., a 25-year-old Canadian manufacturer of single-screw extruders, wants to become better known in the United States.
Deltaplast just signed up QED Inc. of Charlotte, N.C., as its manufacturers' representative. The two companies exhibited together at Plastics Enounter Atlanta.
Dirk Koch, vice president of sales, said the company's new Competition series of extruders is economically priced. For example, the smallest in the line, with a 21/2-inch screw diameter, costs $50,000. The top diameter size is 6 inches.
Features on the air-cooled extruders include bimetallic-lined barrels and heating and cooling elements made from solid cast aluminum.
The company targets profile, pipe, compounding, reclaim, wire and cable and sheet extrusion markets.
Koch said Deltaplast can customize machines.
``We're not afraid of the special-application jobs,'' he said.
The company, which is owned by the Koch family, has 20 employees at its 30,000-square-foot factory. The plant is in Concord, Ontario.
Extreme Coatings promotes services
The Extreme Coatings Division of Surface Engineering & Alloy Co. was pitching its feedscrew rebuilding and coating services at Plastics Encounter Atlanta.
The company in St. Petersburg, Fla., works through screw manufacturers and rebuilders, and machinery manufacturers.
To prepare the screw surface for coating, Extreme Coatings blasts the screw with aluminum oxide grit, which roughens the surface.
To coat the screw, a special gun with a gas mixture melts powder particles and sends them down the barrel at a temperature above 6,000° F. Kinetic energy released when the particles hit the screw create more heat and promote bonding, density and hardness. Technicians then polish the screw.
Extreme Coatings claims its CX1000, a composition of cobalt- or nickel-saturated with tungsten carbide, can at least double the life the screw. Other coatings include combinations of nickel, chromium and chromium carbide and nickel chrome and baron.
