The Clinton-based company is “consolidating to fewer, larger, full-service manufacturing operations in order to better serve our customers with greater scope and scale,” said Nelson Ngai, group vice president of consumer and electronics.

All of the approximately 1,000 workers at Guangzhou have been offered opportunities to relocate to either Shenzhen or to Nypro’s two other Chinese plants at Suzhou in eastern China and Tianjin in northern China, the company said.

When the consolidation is complete, Nypro Shenzhen, which currently has 3,000 employees, will have 120 injection molding machines ranging from 35-500 tons of clamping force. It currently has about 70 presses.

The Shenzhen and Guangzhou plants both make products for consumer and household goods and the electronics industries, as well as some health care products. The Shenzhen plant primarily makes wireless products, while Guangzhou has made a greater variety of electronic products.

The Shenzhen plant, with 460,000 square feet, is nearly three times as large as the 160,000 square foot Guangzhou plant. Nypro said zoning changes creating residential areas around the Guangzhou site “limited the ability to expand the facility.”

White-room manufacturing at Guangzhou will be relocated to a 100,000-square-foot clean room in Shenzhen. About 25 percent of that clean room space at Shenzhen is dedicated to molding, and the rest is used for painting and assembly.

Nypro Tianjin employs 5,000 and Nypro Suzhou 1,500, making Nypro employment in China more than 10,000. All three of Nypro’s plants in China are ISO 13485-certified and offer injection molding, mold building, decoration and assembly.

“This is a big positive step for Nypro as we enhance fully integrated molding/assembly facilities across the industrial landscape of China,” said a company spokesman.
