High‑pressure die casting injects molten aluminum, magnesium, or zinc alloys into steel dies at high speed and pressure. Precision tooling and rapid solidification enable thin‑wall, high‑volume parts used in automotive, electronics, and structural components.
High‑pressure die casting is a fast, cyclic process in which molten metal is injected into a hardened steel die at high velocity and pressures reaching several thousand bar. Aluminum alloys such as Al‑Si or Al‑Mg are widely used due to their good castability and strength-to-weight ratio.The melt—typically aluminum, magnesium, or zinc alloys—is delivered to the shot chamber and accelerated by a hydraulic or servo-driven plunger. The gating system and intensification phase ensure rapid cavity filling and high compaction, enabling thin‑wall structures with excellent dimensional accuracy. HPDC tooling consists of fixed and moving die halves with optimized runner layouts, cooling circuits, ejector systems, and wear‑resistant inserts to withstand thermal fatigue and erosion. Common tooling materials are high quality 5%CrMoV-Hot Work Tool Steels. HPDC is essential for high-volume production of automotive structural components, housings, brackets, transmission parts, and consumer electronics, where tight tolerances, complex geometries, and high surface quality are required.
BÖHLER W300 ISOBLOC is a 5% chromium steel and corresponds to material number 1.2343 (X37CrMoV5-1). Produced via the electroslag remelting process (ESR), this tool steel has very high hot toughness as well as good hot hardness and very good resistance against heat-checkings. The combination of these properties makes it a top performer in high- and low-pressure die casting as well as in closed-die and open-die forging. In addition, this material has very good polishability and is therefore also often used as a molding material for plastic injection molds.

This tool steel has good hot toughness as well as a very high hot hardness and resistance against heat-checkings. Compared to an X37CrMoV5-1 (material number 1.2343), the steel has an increased molybdenum content, which significantly increases its thermal resistance and thus makes it the ideal material in die closed-die forging, open-die forging and extrusion.
Read MoreBÖHLER W320 ISODISC is a 3% chromium steel and corresponds to material number 1.2365 (32CrMoV12-28). This tool steel has good hot toughness as well as a very high hot hardness and resistance against heat-checkings. Compared to an X37CrMoV5-1 (material number 1.2343), the steel has an increased molybdenum content, which significantly increases its thermal resistance and thus makes it the ideal material in die closed- and open-doe forging. Due to the lower chromium content, reduced through-hardenability occurs which limits its applications to rather smaller tools.
Read MoreBÖHLER W350 ISOBLOC is a material produced by the electroslag remelting process (ESR) which is particularly suitable for use in large casting and forging molds. Although the steel can be classified as a 5% chromium steel, the chemical composition has been chosen to provide the best possible through-hardenability without any loss of toughness or resistance against heat-checkings. These properties make the steel the perfect choice to produce very large die casting molds, for example for mega- or giga-casting.
Read MoreThe BÖHLER W360 AMPO is the powder equivalent of the W360 ISOBLOC. Due to its chemical composition, the material belongs to the product group of hot-work tool steels. After hardening and tempering, it can achieve a hardness of up to 57 HRC with very good toughness properties. Its high temperature wear resistance, heat resistance and toughness characterizes the material. Applications: Printed components with conformal cooling for die casting applications, wear protection layers and repair work in mold making using laser cladding.
Read MoreBÖHLER W360 ISOBLOC is a material produced by the electroslag remelting process (ESR), which has been specially adapted for use at high tool hardnesses in the range of 51-57 HRC. Although the steel can be classified as a 5% chromium steel, the increased carbon and molybdenum content coupled with state-of-the-art manufacturing technology ensures that BÖHLER W360 ISOBLOC still shows a very good toughness and an exceptionally good thermal resistance, even at high hardness levels. These properties make the steel the perfect choice for smaller components in the die casting sector (e.g., mold inserts, cores, core pins, ejector pins, etc.). The material also is frequently the preferred choice for closed-die and open-die forging tools due to its high wear resistance. Because of this excellent wear resistance and the high toughness, BÖHLER W360 ISOBLOC is also frequently used for cold work applications and as a molding material for plastic injection molds. The Steel also is available as powder material for metal-3D-printing under the brand name BÖHLER W360 AMPO.
