In an effort to increase efficiencies and reduce costs for customers, Westec Plastics has invested in three new Arburg two-shot injection molding machines. The two 550-ton and single 275-ton machines are equipped with indexing platens to rotate the moving half of the mold, such that the first shot is positioned for the second shot of material. The purchase is part of a $3 million investment on facility improvements by the Livermore, CA, company.

“We have seen numerous applications over the past several years that are ideal for two-shot injection molding, and now we can better support our customers by offering this technology,” said Tammy Barras, President of Westec Plastics. The technique is a more cost-effective alternative to traditional over-molding, said the company.

Other recent enhancements include the addition of 9,200 square feet of floor space since 2020 and the purchase of eight new machines. Along with the two-shot Arburg presses, Westec has added three injection molding machines, sized 110, 170, and 28 tons, to its battery of equipment.

Westec has added several manufacturing cells, including an ISO Class 8 cleanroom for the two-shot molding machines, an ISO Class 7 cleanroom for secondary operations, and two ISO Class 8 portable cleanrooms. To support rising demand for medical molding, the company expanded its ISO Class 8 hard-walled molding cleanroom. A new Keyence IM-7030T instant measurement system was installed for quality control.

Westec has also invested in equipment for secondary operations, including a KP08 Cupslide pad printer, Branson Mini II linear vibration welder, Branson ultrasonic welder, and Minilase XL laser engraver. Three new collaborative robots and three Cartesian robots round out recent purchases to offer customers a well-rounded package of services.
