Hong Kong injection press maker Chen Hsong Machinery Co. Ltd. has earned a utility model patent on a newly designed circular platen, which the company claims reduces the concentration of stress.
The design consists of a rectangular base plate with a center hole, four guiding holes, one inner circular-shaped reinforced structure at the back of a rectangular base, and reinforced wedges in between the inner and outer reinforced structure. The outer structure is either circular or oval-shaped, building on top of the base plate.
A circular platen streamlines the stress distribution and prolongs platen life. The platen offers better strength and stiffness, with less material used, Chen Hsong claims.
