Midway Corporation


All MoldMAX products are high performance alloys specifically designed for the plastic processing industry. These alloys offer a unique combination of thermal conductivity and strength that provides significant advantages for the molding process, including:

  • 15–50 % shorter cycle time
  • Improved plastic part dimensional control
  • Better parting line maintenance
  • Corrosion and wear resistance
  • Excellent machinability

The MoldMAX product line offers a variety of mold alloys that can fit any application requirement:

MoldMAX HH® • MoldMAX LH® • MoldMAX XL® MoldMAX V® • PROtherm®


Thermal Conductivity Advantage

Mold designs that optimize the superior combination of thermal conductivity and strength of MoldMAX alloys will provide rapid, uniform and controlled heat removal from the plastic part. The immediate benefit is less in-mold and post-mold warpage of plastic parts, as well as shorter cycle time and better dimensional control. In addition, hot runner and manifold designs that include MoldMAX alloys will result in more uniform temperature control of the plastic melt and higher quality plastic parts.

The MoldMAX® Advantage in Injection Molding

MoldMAX is engineered for use as the core material in concert with steel mold bases and cavities. One of the most important functions of an injection mold is to act as a heat exchanger. The core performs the majority of the heat removal in the typical mold. MoldMAX with up to 10 times the thermal conductivity of tool steel, reduces cycle time 15 – 50%. The cost savings of these reductions can be substantial.

Health & Safety

Handling copper beryllium in solid form poses no special health risk. Like many industrial materials, beryllium-containing materials may pose a health risk if recommended safe handling practices are not followed. Inhalation of airborne beryllium may cause a serious lung disorder in susceptible individuals. The Occupational Safety and Health Administration (OSHA) has set mandatory limits on occupational respiratory exposures. Read and follow the guidance in the Material Safety DataSheet (MSDS) before working with this material.
