Improving Die Cast Tooling
What if you could find a way to increase tool life, reduce downtime, and increase capacity in your die casting operation? With Mi-Tech Metals’ High Density 17.7 tungsten alloy, Diemitech®, you can.
- Diemitech® has three times the ductility of comparable materials, making it significantly less brittle and more durable for less chipping and longer tool life.
- Diemitech® has three times the thermal conductivity of steel, which improves cycle times and solves heat transfer problems such as porosity and shrinkage.
- Diemitech® has a low affinity for iron, eliminating die soldering problems and improving product quality.
Greater Durability for Longer Tool Life
Core pins and insert details are less susceptible to breakages because High Density 17.7 Diemitech® has strong tensile properties and high thermal conductivity. Unlike other alloys used in die cast tooling, Diemitech® resists chipping and breakage, leading to less downtime to change out broken cores.
The combination of Diemitech’s low thermal expansion and high thermal conductivity reduces heat checking and improves tool life.
Reduce Downtime While Improving Quality
As Diemitech® has a high thermal conductivity and low affinity for iron, core pins will stay cool and aluminum will not adhere to the pin. By eliminating die soldering, you won’t need to change out, clean, or polish core pins, and you’ll reduce reject parts, resulting in less machine downtime and improved quality.
Porosity in castings can cause a high reject rate by causing casting leakage, and problems with drilled and tapped holes. Porosity issues can be solved by speeding up solidification at these locations with a high thermally conductive alloy such as Diemitech®.
Increase Cycle Time to Increase Capacity
Inserting Diemitech® at thick sections of the casting dramatically improves solidification rates. When you use High Density 17.7 Diemitech®, solidification occurs up to 10 seconds faster than in dies without Diemitech® shot blocks. Using Diemitech® increases cycle time so you can increase your plant’s production capacity.
From reducing downtime to increasing capacity, from eliminating die soldering to improving die cast tooling, High Density 17.7 Diemitech® is the logical choice for solving issues at specific locations in die cast tooling.
