Application

YAMAWA's PM taper pipe taps are suitable for tapping hardened mold steels with a hardness of 30-45HRC

Made with DIN length blanks.
The DIN  length provides excellent chip evacuation.

Made with our new powder metals HSS.
Powder metals HSS has excellent wear resistance.

Cutting surfaces have oxidization treatment.
Oxidization treatment (OX) is applied to the surface treatment which has excellent welding resistance.

Unique cutting edge design is suitable for high hardness materials.

 

DIN overall length provides excellent chip evacuation.

Ex.PT/Rc 3/8-19

Excellent chip evacuation

Excellent surface finish

 

Benefits of DIN overall length

●Chips do not interfere with the holder. 

●Tapping fluid can also be supplied directly to the taps cutting edges.

 

Case reference

What is a plastic mold?

Many items such as refrigerators, washing machines, TVs, home appliances smartphones, automobiles,construction machines, ships, airplanes and other transportation equipment, have components which are
produced in molds.

 

The injection mold is widely used in many industries for producing plastic products.lnjection mold is a molding method in which molten plastic is injected into a mold. It is then cooled to solidify, and then the finished part is removed from the mold.Cooling holes are required for cooling molded products. Taper pipe screws are used at the entrance of the cooling holes.The screw size depends on the size of the molded product.  Most common sizes are 1/8 or 1/4 of Rc (PT) but can range up to  1 inch.

Plastic mold cooling holes

Several Rc (PT) screws are used for cooling holes.

With the mold having a hardness of 30~45HRC, and the fact that it has tapered threads, it can causes tapping issues such as torn threads, premature wear of taps, along with chipping and breakage of taps.With such tapping conditions in mind, the products we have developed are PMST OX Rc and PMSP OX Rc, which are taps for PM pipe threads.
