Die casting quality control

Die casting,casting

Die casting as a kind of special casting method, compared with other casting method, its basic feature is the liquid metal at high speed for filling out high pressure to the mold filling, however, due to the filling of die casting method of injection and metal mould rapid cooling and high production efficiency, the damage to the mould, make the die casting inevitably produces many defects, some defects and die casting method and the burden, others can be avoided, some defects will not affect the performance of the die casting, so will not result in the casting scrap, and other defects may affect the performance of casting and become waste.Quality is the lifeline of the enterprise, is one of the important pillars, improve enterprise competitive ability is the important condition to improve economic efficiency of enterprises, therefore, improve the quality of die casting, both die casting enterprise's economic benefits, social benefits or reduce the waste of resources, is very beneficial.

Die casting quality including the appearance quality, internal quality and use of quality, appearance quality refers to the casting surface roughness, surface quality and dimension tolerance, form tolerance and quality deviation, etc.;Inner quality refers to the chemical composition of casting, the physical and mechanical properties, microstructure, and in the inner hole of casting, inclusion and crack, etc;Use quality refers to the castings can satisfy various application requirements and working performance, such as wear resistance, corrosion resistance, and cutting, welding, etc.
