Box quenching furnaces, also known as hard mold forging or durable forging, involve pouring molten aluminum alloy into a metal mold to obtain castings. These furnaces often use metal cores, but can also employ sand cores or shell cores. Compared to pressure forging, the metal molds in aluminum alloy melting furnaces have a longer service life.

Forge Strengths

(1) Strengths

Metal mold cooling is faster, resulting in finer casting structures, which are suitable for heat treatment strengthening. The mechanical properties are approximately 15% higher compared to sand mold forging.

Box-type quenching furnace ensures stable casting quality, with better surface roughness than sand mold forging and a lower scrap rate.

Good labor conditions, high productivity, and ease of worker adaptation.

(2) Drawbacks

Metallic thermal conductivity is high, but the filling capability is poor.

Metallic wood bodies are non-permeable. Appropriate measures must be taken to effectively vent.

Metal is non-retractable and prone to cracking and deformation during solidification.
