Reduce cooling time and boost output in plastic injection molding
Moldmax is a high-hardness beryllium copper for mold applications that conducts heat several times better than steel, reducing cooling cycle time in plastic injection and blow molding while offering hardness that resists wear.
Overview
In mold applications, heat that cannot be removed fast enough is the bottleneck of the production cycle. Moldmax draws heat out of the part quickly, shortening the injection cycle and reducing warpage and hot spots.
Several grades are available depending on the balance between hardness and thermal conductivity — for example Moldmax HH (high hardness) and Moldmax XL / Protherm (high conductivity). Our team helps you choose to match the mold.

Material highlights
Reduce cooling time (Cycle Time)
High thermal conductivity draws heat out of the part quickly, shortening the injection cycle and increasing production capacity.
Reduce warpage and hot spots
Distributes heat evenly throughout the mold, reducing thermal stress that distorts parts.
Wear-resistant in continuous production
High hardness (especially the HH grade) helps cores and inserts resist wear in high-volume production.

Frequently asked questions
How does Moldmax reduce cooling time?
Moldmax is a beryllium copper that conducts heat several times better than steel, pulling heat out of the plastic part faster so the injection cycle time shortens, raising output and part consistency.
Should Moldmax replace the whole mold or just part of it?
It is usually used in the hard-to-cool areas — cores and inserts around hot spots — to boost cooling while controlling cost. Our team advises where it pays off most.
Which Moldmax grade should I choose?
Choose the high-hardness grade (HH) for wear resistance, and the high-conductivity grades (XL / Protherm) for maximum heat extraction. Our engineers help match the grade to your mold and resin.
