Equipped for High Temperature, High Performance Molding HPTP's mold at temperatures three to five times higher than standard plastics. For example, Torlon molds at 370 °C; PEEK at 350 °C. HPTP have unique molding characteristics. Semi-crystalline and amorphous polymers melt, flow and cool differently, as do filled and non-filled resins. Control of the injection molding process is vital. China Array uses Welltec injection molding machines with Bosch hydraulic valves and Intermot high torque motors, nitrate hardened alloy screws and barrels, and ceramic heater bands. The machines develop pressures and speeds 40% higher than others in their class. Xaloy screw/barrel assemblies are used for specialized applications. Wittmann oil mold temperature controllers maximize cycle effectiveness. Matsui desiccant resin dryers prepare resins to tight drying tolerances, which are measured with a Sartorius-Omnimark moisture analyzer down to 500 ppm.

INJECTION MOLDING

China Array Plastics, and its wholly owned subsidiary, China Array Wuhan, specialize in injection molding High Performance Thermoplastics (HPTP) components. The company's broad molding capabilities, exceptional engineering talent, and long history of manufacturing in China make it an attractive option for OEM's, distributors, and designers seeking high performance injection molding in China.

Specialists in Molding HPTP's

Molding HPTP's is significantly more difficult than molding standard plastics. HPTP's require extensive upfront engineering. Extremely high melt temperatures (370+ degrees C) and unique flow characteristics necessitate specialized equipment for resin preparation and molding. These factors limit the number of HPTP molders in China. China Array's HPTP molding capability is based on the knowledge and experience of its outstanding HPTP Applications Engineers, and on the firm's 28 year history of manufacturing industrial products in China.

By investing in state-of-the-art injection molding machines and the specialty auxiliary equipment (see side bar) required for HPTP molding, and providing training and supervision, China Array has created a world class HPTP injection molding operation in Wuhan, China.

Integrated Production

The knowledge, experience and industry connections of China Array’s materials, design and process engineers cuts across virtually all market segments worldwide providing a powerful “front-end” for China Array's customers.

A fully integrated high performance thermoplastics (HPTP) molder in China provides a competitive “back-end”. The combination of talented multinational engineers and solid Chinese manufacturing positions the company to integrate forward into the design and development of products, a growing trend in several industries, and backward into doing complete production, assembly and packaging in China, another growing trend. The combination allows China Array to assist its customers in exploiting opportunities in several technological niche markets both in the West and in Asia. China Array has implemented various high end applications for its customers.

Consistent Quality

In addition to understanding high-end plastics, China Array also understands manufacturing in China. Over 28 years, the company has perfected Quality Control methods geared toward Chinese manufacturers that concentrates on consistency of quality (historically a stumbling block for Chinese manufacturers). The company's injection molding facility, located in Wuhan, China, is a Wholly Owned Foreign Enterprise (WOFE) owned 100% by China Array Plastics, a US Corporation. This ownership arrangement gives China Array complete production control and accountability.

Wuhan, China

China's Industrial Heart Land

China Array's production facilities are located in Wuhan, China: the capital of Hubei Province and China's fifth largest city with a population of eight million. Known as the 'Thoroughfare to Nine Provinces", Wuhan is approximately 400 miles from Shanghai in the east, Zhongqing in the west, Hong Kong in the south and Beijing in the north. The city straddles the Yangtze River at the nexus of the main river, rail and highway routes running north/south and east/west across China. It is perfectly situated for supplying customers within China or reaching coastal ports for export.

Mission Statement: To provide customers expert engineering, design and materials advice , and a fully integrated molding operation for a consistently superior product at a competitive price.
