1.Improve the abrasion resistance of aluminum alloy die-casting

Induction hardening was first applied to the surface of the crankshaft journal, and its purpose was to improve the abrasion resistance of the crankshaft. In the past, the crankshaft was quenched and tempered, and induction hardening greatly improved the wear resistance of the crankshaft journal.Die casting machine.

2. Improve the fatigue strength of aluminum alloy die casting

The further application of induction hardening is to increase the fatigue strength of the quenched parts, and induction hardening doubles the fatigue strength of the crankshaft, and some products have a crankshaft fatigue strength of ≥700MPa.

3. Reduce distortion

Long process time, large distortion after quenching; while gear induction hardening, especially synchronous dual-frequency (SDF) gear quenching, has short process time and small distortion, which improves the precision of aluminum die casting and reduces noise.

4. Energy saving, material saving, labor saving and environmental protection

Induction quenching saves material costs; induction heating is local heating and quenching, which takes a short time and therefore greatly saves energy. Induction quenching can realize automated online production, which saves labor, has no oil pollution, no harmful gas emissions, so as to protect the environment.

5. Replace deep carburizing

Deep carburizing is a process with long cycle and high power consumption. In recent years, foreign countries have successfully used induction hardening to replace deep carburization, and achieved good results.
