Welltec Machinery Ltd., Hong Kong, is showing a Ge series all-electric injection molding machine with 105 tons of clamping force at NPE (Booth S12017). The company also will exhibit an Se 130-ton servo hydraulic machine. Applications of the Welltec machines include automotive, household electric appliances, electronics, and packaging.
The electric Ge105 machine uses ball screws for movement and a small hydraulic circuit for pressure after the ram is locked. The Ge clamping system ensures parallelism and minimizes platen deflection, according to the company. The rapid-response clamp design allows immediate clamping, avoiding the time otherwise required for toggle-system lock-over. A lock-nut design eliminates pressure on the ball screw and servomotor, preventing overheating of the servomotor.
A high-precision, mold-protection circuit senses forces below 3 kilograms. B&R controls provide for overall accurate machine performance, the company said. Off-the-shelf, internationally recognized components provide ease of operation and service. All Welltec machines offer a three-year "bumper-to-bumper" warranty and package, including parts. Local technicians provide service nationwide.
Welltec North America President Rodney Sams said that the North American segment of the business was founded in March 2013 and averages sales of four machines per month. Sams said that the Pacific, Mo., company's staff has over 20 years' experience in the bearing and power transmission industry as well as 22 years of experience with injection molding machines.
Welltec Machinery Ltd. is a subsidiary of Cosmos Machinery Ltd., which is a wholly owned subsidiary of Cosmos Machinery Enterprise Ltd., a publicly listed company in Hong Kong, focusing on manufacturing of injection molding machines.
Besides the Americas, Welltec has a presence in Europe, Asia, the Middle East and Africa, and manufactures injection molding machines in China. Welltec established a joint venture, JH-Welltec, in Ahmedabad, India, in 2010 to assemble and produce servo-driven injection machines with up to 1,000 tons of clamping force for the Indian market.
