Moulding & Tooling

One of the reasons we’re constantly advancing our aluminum alloys is the demanding requirements of the mold and tool construction industries. Aleris Europe has continuously adapted to the ever-changing needs of this important industry sector. Today the optimum plate material can be selected from a multitude of interesting alloys.

In addition, molds made of aluminum alloys have successfully entered the market of plastic blow-molding and thermoforming. That’s because aluminum molds have a number of interesting advantages when used in place of steel molds:

• Shorter machining / cycle time
• Better thermal conductivity
• Weight saving for easier handling of large tools
• Smoother surface finish after machining
• Short-brittle spiral chips for easier processing and handling (chip shape)
• Positive impact on tool life
• Significant overall cost savings

Aleris products

• The classic alloy: GIANTAL
• The universal alloy: WELDURAL
• The high-strength alloy: HOKOTOL
• Other alloys for different applications

You’ll find more detailed technical information about the machining process and the optimal utilization if it, plus specific strengths and advantages of the various Aleris alloys, in the literature below.

Please see our brochure Aluminum for mould and tool construction – Economical aspects and Aluminum for mould and tool construction – Machinability, as well as our datasheets Hokotol, Weldural, and Giantal.
