Computer Plastics Inc. of Hayward, Calif., has upgraded its capabilities with new electrical discharge, milling, molding and drying equipment worth more than $577,000.
In December, the firm installed three Sumitomo injection molding machines with clamping forces of 33, 55 and 88 tons.
Earlier, Computer Plastics acquired a 220-ton Cincinnati Milacron press with Camac 486 PC-based controls and a 20-ounce shot size, plus a 105-ton Sandretto with Zeph 100 controls. Each machine is connected to an IQMS real-time monitoring system.
With the additions, the company has 15 molding machines, with clamping forces of 25-220 tons.
In February, Computer Plastics will begin using a Bry-Air drying system with a minus 40° F dew point to dry each material for each press.
Computer Plastics' toolroom has added a Sodick Moldmaker electric discharge machine and a Sharp milling machine with Proto Trak M3 controls.
The firm specializes in processing engineering resins such as polyphenylene sulfide and polyetherimide, and claims to be one of the largest polyetheretherketone processors in northern California, said George Houle, instructor and process engineer.
Houle and others are designing a new process and control training program that will include hands-on, seminar and interactive CD-ROM segments.
Computer Plastics employs 35, including five mold makers with an average of 18 years with the firm.
The firm occupies a 15,000-square-foot building and generates annual sales of $3 million to $4 million by supplying components principally for analytical test devices and electrical connectors. Other applications involve the medical, industrial and computer industries.
Wayne Harshbarger and a friend formed the firm in 1969, and Harshbarger has been the principal owner and operator since 1984.
