Houseware moulds need to meet various working conditions and process performance requirements during the manufacturing process, with material selection being crucial. The following are the key properties that houseware moulds materials need to possess.
Houseware moulds often face plastic deformation of the blank and surface friction during use, making wear resistance one of its most basic and important properties. The hardness of the material directly affects its wear resistance; the higher the hardness, the better the wear resistance, which can reduce wear and extend the mold's service life.
Molds work under harsh conditions and frequently endure impact loads, thus requiring high strength and toughness to prevent sudden fractures and improve operational stability.
Long-term cyclic stress can easily lead to fatigue fracture of the mold, so mold materials must have sufficient strength, toughness, and fatigue resistance to ensure long-term stable operation.
Some houseware moulds work in high-temperature environments, and materials need to have good tempering resistance to ensure they maintain hardness and strength even at high temperatures.
Some molds undergo repeated heating and cooling processes, so materials must have high thermal fatigue resistance to prevent surface cracks and failures due to temperature changes.
During the mold manufacturing process, good process performance can improve manufacturing efficiency and product quality:
Materials should have good forgeability, making them easy to forge and process during manufacturing to ensure mold quality and reduce production costs.
The annealing process should have broad applicability and stable annealing effects to guarantee the appropriate hardness and strength of the mold material.
Materials should have good machinability, which can reduce tool wear and surface roughness while improving processing efficiency.
In high-temperature environments, materials should have good oxidation and decarburization resistance to maintain surface stability and extend service life.
The hardened material should have uniform hardness distribution and good hardenability to ensure the mold's surface wear resistance and service life.
When selecting houseware mould materials, economic factors are important considerations. It is necessary to choose cost-effective materials that guarantee performance: By selecting materials that meet performance requirements, are moderately priced, and are easily accessible, manufacturing costs can be effectively reduced and market competitiveness improved.
