1. Nylon parting lock.

+ Allows adjustment of friction force the base plate and resin sleeve by tightening loosening, tapered bolt, made of a high-grade Nylon. This parting lock feature excellent corrosion and heat resistance properties.
+ Resin sleeve by itself has heat-resistant temperature of 150 but use it at 80 or less because the durability will reduce due to tightening stress by the tapered bolt in the practically continuous use.

2. Steel parting lock.

+ It Enables well-balanced mold opening/closing through its mechanism composed of a belleville spring, internal rollers and lock rollers.
+ The rollers prevent uneven wear.
+ A lock bushing’s vertically symmetrical design allows a worn piece to be reused by reinstalling it in reverse.
+ A lock holder’s black recess it to be used even on a stepped mold plates.
+ For heat proof type, the adjusting bolt differs from standard type for identification.
