Diaphorm process cuts part cost 20-70
A new way to make short-run thermoplastic composite parts cuts production costs, according to its inventor, the Diaphorm Division of Solectria Inc.
``Our process fills the gap between hand layup and compression molding,'' said Bob Miller, general manager of the Diaphorm Division. ``It's ideal for structural composites in lot sizes between 1,000 and 100,000.''
The company in Woburn, Mass., said the Pressure Diaphorm process can make parts that cost 20-70 percent less than compression molded parts. It works like compression molding, but needs machinery and molds that are much less expensive. It uses a single-sided mold, an oven to melt the resin and a rubber diaphragm to form the material to the shape of the mold.
Depending in production volumes, the mold can be made of wood, composite or aluminum - costing one quarter the price of traditional tooling for compression molding, Solectria said.
Pressure Diaphorm can mold parts in polypropylene, urethane and some nylons using common continuous reinforcing fibers such as glass, carbon and aramid.
The company is already supplying prototype quantities of motorcycle helmets, industrial caps and structural beams for kayaks.

Husky introduces 2 high-speed robots
Husky Injection Molding Systems Ltd. has introduced two high-speed robots.
Husky said its Integrated Dual Carriage Inline robot was designed to meet the product needs of its customers when they use Husky's multimold carrier systems, which can run two independents molds in the same machine.
``The dual carriages are independently controlled and ride on a common beam mounted parallel to the machine,'' said Joe Calomino, robotics product manager at the Bolton, Ontario-based company. The dual-carriage design enables the robot to pick up parts using traditional end-of-arm tooling. Each carriage can remove a part from each mold, while also allowing each part to be placed independently for downstream handling.
The robots can handle a payload up to 176 pounds per head.
Husky also introduced its G series robot for PET preforms. Mike Urquhart, vice president of PET Systems, said the latest version of the company's take-out plate and robot should greatly reduce production stoppages. ``Part transfer issues can become the main factor limiting higher productivity, particularly on short, bell-shaped preforms,'' he said.
On other PET-related news, Husky said it now can refurbish PET molds in a customer's plant. In the past, Husky has offered complete rebuild services that brought every aspect of the mold to like-new condition. Under the new, less-expensive program, Husky also can target only specific problem areas of the molds.
The mold repair program comes in three tiers, with varying scopes and prices. Husky said all are designed to reduce thread flash, minimize mold downtime to as little as one week and keep costs to a minimum.
