Hydromechanical IMM overcomes platen deflection issue

HPM Corporation has provided a 5000-ton, two-platen, hydromechanical Next Wave series injection molding machine for GM Saturn Corporation to mold interior body parts and panels for the division’s new mid-size LS sedan.

The HPM machines have superior hydromechanical clamping technology which addresses a problem of platen defection GM Saturn was experiencing with certain toggle machines.

“The slide guidance system utilizes a decoupled platen arrangement with variable spring coupler elements. This, combined with platen design and clamping force load distribution, reduces potential for distortion of the mold mounting surface,” says Michael McKee, president of HPM’s Injection Molding Business Unit.

The Next Wave series machine has a simple clamp locking mechanism and tiebars which retract with the moving platen for better access in the mold area. Flash, premature mold wear and other problems are eliminated as a result of the platen design.
