EXEO-NPR1

For injection molding machine parts for high-grade plastics

EXEO-NPR1

NACHI developed the EXEO series alloys incompany-wide combined and connectedengineering system by first analyzing anddetermining necessary characteristics and thenapplying Nachi original alloy design and special
melting technologies.
EXEO-NPR1 is the best material for injection
molding machine parts such as screws used formolding high-grade plastics.
LJoint development with an university analyzed thebasic mechanism of corrosion by using a new
method to evaluate corrosive wear by plastics.
LFM Alloy production facilities and alloy design
technologies make superior resistance to corrosive
wear as plastics injection molding machine parts.
LProprietary heat treatment technologies give theproducts the very best heat treatment quality.
