Plastic Mold Steel

Plastic Mold Steels

What do you need in your mold steel?

Machinability? Weldability? Permeability?
Our steels offer you uniform hardness for even machinability and clean welds, resulting in
superior molds. Specific steels offer advantages for polished or textured finishes �
porosity for gas venting during injection molding � prehardening for high-precision molds
that will not deform � and more.

Products

Porcerax II
Porcerax II is a sintered, porous metal with porosity in the range of 20 to 30% by volume.
A system of interconnected pores with an average diameter of 7 or 20 micron is
dispersed throughout the Porcerax II material.

Using Porcerax II in appropriate areas, eliminates gas buildup, reduces injection pressure,
lowers cycle times, gloss levels and substantially reduces scrap and reject rates.

NAK 55

NAK55 is a 40 HRC pre-Hardened, high performance, high precision, mold steel.
Applications include plastic molds, rubber molds, jigs & fixtures, and press dies.
Features:
Machines 30- to 40 percent faster than P20
Pre-hardened to 38-42 HRC
Uniform microstructure & hardness (40 HRC between surface & interior)
Never needs stress relieving
Highly weldable, HAZ gets softer not harder (re-age harden to bring back to 40 HRC)
EDM layer is easy to remove

NAK 80

NAK80 is a 40 HRC pre-Hardened, high performance, high precision, mold steel.
Applications include plastic molds, rubber molds, jigs & fixtures, and press dies.
Features:
Machines up to 20 percent faster than 30 HRc P20
Pre-hardened to 38-42 HRC
Uniform microstructure & hardness (40 HRC between surface & interior)
Never needs stress relieving, even after heavy machining
Highly weldable, HAZ gets softer not harder (re-age harden to bring back to 40 HRC)
EDM layer is easy to remove

PX5

PX5 is a modified P20, high performance, high precision, mold steel. Applications include:

plastic molds
