The high-rigidity clamping unit enables the use of wider platens and achieves high-precision stabilized molding.Platen Parallelism and mold positioning accuracy is achieved by using a high efficiency platen support mechanism, with extra long platen guides.JSW
,s original 5-joint, internally folding toggle
mechanism attains improved faster cycle molding.The stationary platen and the movable platen, consist of a box construction with reduced weight and increased rigidity, exerts a clamping force evenly distributed over the mold surface.The pre-tensioned tie bars promote durability and decrease vibration during the mold open/close action.The flat press platen structure enables minimizing of wall-thickness fluctuation of molded products.
Flat Press Platens Mechanism
Clamping unit
The horizontal tie bar distances are extended further than conventional machines to allow for wider molds.
The opening is made larger to allow the stripper mechanism in the mold to be easily linked to the knockout plate on the machine.

The weight of the product processed in the central section of mold increases due to the deformation of platen in the center.
Mold clamp force is uniformly distributed to the entire surface of the platen.
