Die Casting

High-Pressure Die Casting

In the process of high-pressure die casting, elevated pressure is employed to quickly fill the mold and create fine details. The high pressure results in a more precise surface finish. This method is suitable for producing intricate and complex parts with thin walls. Consequently, it is well-suited for manufacturing components and parts used in various industries such as automotive, aerospace, and electronics. High-pressure die casting is particularly effective for the production of small to medium-sized castings.

Low-Pressure Casting

In low-pressure casting, molten metal is introduced into the mold through a controlled process with low pressure. This method is especially suitable for large-volume parts like wheel rims. The produced castings exhibit good tightness and excellent surface quality as oxidation in the mold is minimized. Compared to high-pressure casting, low-pressure casting tends to be slower due to lower injection pressures. The use of our Thermodur 2383 Supercool is optimal for its extremely high thermal conductivity, allowing for rapid temperature equalization and reducing the cycle times of the casting processes.

The selection of steel should be based on the application, mold design, casting alloy, and other factors, taking into account the comprehensive profile of each type of steel. Feel free to reach out to us; we are happy to advise you on your specific application.

We recommend the use of our high-performance hot-work steels from the Thermodur® Superclean series for durable, reliable, and cost-effective molds. These Electro-Slag-Remelted (ESU) steels provide the required profile with the highest toughness values, combined with a homogeneous structure and fine grain size.

The Thermodur® Superclean series from the Swiss Steel Group includes Thermodur® 2343, 2344, 2367, E38 K, E40 K, and 2999. Especially, Thermodur® 2343 Superclean proves to be a versatile all-rounder, excelling in the processing of lightweight metal alloys due to its high-temperature resistance and toughness. For more specific requirements, Thermodur® 2344 Superclean and Thermodur® 2367 Superclean are available, offering improved tempering and wear resistance, as well as increased high-temperature resistance.

In addition, we also provide standard materials in our special EFS condition with an extra-fine structure, such as Thermodur® 2343 EFS, Thermodur® 2344 EFS, and Thermodur® 2367 EFS, all in non-remelted quality.
