MOLDMAX® & PLASTICS ALLOYS FOR INJECTION AND BLOW MOLDING


Our MoldMAX family of plastic tooling alloys are specifically designed to shorten cycle time and improve part quality for the plastic processing industry by providing thermal conductivity along with high strength. MoldMAX® alloys are used in injection mold components and core / cavity inserts, blow mold pinch-offs, neck rings and handles inserts, hot runner system injection nozzles and manifolds.

MOLDMAX® CASE STUDIES – IMPROVING INJECTION & BLOW MOLDING

Textron Automotive Case Study - MoldMAX increased the efficiency of injection molding of instrument panels.

RT Technologies Case Study - Increased cycle time by 20% when making cavity mold inserts with MoldMAX.

First Plastics Case Study - Eliminated warping and improved part quality for skate/bike ramp molds with MoldMAX.

We offer a variety of MoldMAX alloys to meet the high production demands of the plastic processing industry, including:

MoldMAX HH®

MoldMAX HH is a premium plastics alloy with hardness and strength comparable to standard tool steels, but its thermal conductivity is four to six times higher. Its high hardness provides durability in applications where other high conductivity copper alloys fail. This alloy is used for injection mold cores and cavities as well as pinch-offs for blow molds.

MoldMAX HH alloy is available in rounds, square and rectangular bars, plate and forged rings. Download our MoldMAX HH data sheet.

MoldMAX LH®

MoldMAX LH is another premium copper beryllium plastic tooling and moldmaking alloy, It provides hardness and strength comparable to standard AISI P-20 tool steel, but with a thermal conductivity that is five times higher. This alloy is commonly used for injection mold cores and cavities and pinch-offs for blow molds.

MoldMAX LH is available in rounds, square and rectangular bars, plate and forged rings. Download our MoldMAX LH data sheet.

MoldMAX V®

MoldMAX V is a high conductivity, moderately high strength, copper nickel silicon chromium alloy. Commonly used for injection mold cores and cavities.

MoldMAX V is available in rounds and plate. Download our MoldMAX V data sheet.

MoldMAX XL®

MoldMAX XL is a high strength copper nickel tin mold alloy with good thermal conductivity. The alloy’s hardness is comparable with AISI P-20 tool steel, but its thermal conductivity is two to three times higher.

MoldMAX XL is available in rounds, square and rectangular bars and plate. Download our MoldMAX XL data sheet.

PROTherm®

PROTherm is a high conductivity copper beryllium alloy with good strength. This alloy has the highest conductivity of any alloy with tensile strength in excess of 100,000 psi. It is commonly used for injection mold cores, blow mold cavities and hot runners.

PROtherm material is available in rounds, square and rectangular bars, plate and forged rings. Download our PROtherm data sheet.

ThermoMet

ThermoMet (UNS C18000) is a copper nickel silicon chromium alloy with high strength and hardness along with high electrical and thermal conductivity. In plastic molds it can shorten cycle times, improve part consistency, improve line maintenance and is corrosion resistant. For resistance welding it offers longer wear and resists mushrooming. It is also RWMA class III.

To learn more about ThermoMet (C18000) physical and mechanical properties, forms and sizes, download our ThermoMet data sheet.

WeldPak & WeldPak XL

WeldPak copper beryllium is used as filler metal for TIG (GTAW) weld repair of copper beryllium, PROtherm and the MoldMAX family of alloys. It is commonly used to repair cracks or to build up worn surfaces. WeldPak meets UNS C17200.

WeldPak XL is used as filler metal for TIG (GTAW) weld repair of MoldMAX XL. It is commonly used for repairing cracks or building up worn surfaces. WeldPak XL meets UNS C72900.
