Considerations For Die-casting Conditions
Considerations for die-casting conditions:
Die-casting machine, die-casting alloy and die-casting mold is the three major elements of die-casting production, are indispensable. The so-called die-casting process is the three elements of the organic combination of the use of a stable rhythm and efficient to produce the appearance of good quality, size, pattern or agreement to meet the requirements of qualified castings, and even high-quality castings.
Material melting temperature, injection mold temperature and melt temperature;
Finally, the situation of the die-casting products to be trimmed in order to obtain a perfect workpiece. Die-casting mold operating temperature selection principle:
1) mold temperature is too low, the casting structure of the internal loose, difficult to air discharge, difficult to shape;
2) mold temperature is too high, the casting internal structure is dense, but the casting easy "welding" attached to the mold cavity, stick mold is not easy to discharge castings. While too high temperature will make the mold itself expansion, affecting the casting size accuracy.
3) mold temperature should be selected in the appropriate range, the general test after the appropriate temperature control as well. Die casting conditions of the Notes can be summarized as the following two aspects:
* Material melting temperature, injection mold temperature and melt temperature;
Casting die production, need to rely on die-casting machine equipment to complete, die-casting machine is the basis of die-casting production, die-casting equipment, the technical level determines the quality and level of die casting castings, so in order to promote the development of die casting industry must give priority to the development of die castings equipment. China's die-casting casting power, but in the level of production technology and industry equipment to be improved, China's second Five-Year Plan clearly pointed out that the development of the casting industry's main tasks are: priority development of major technical equipment, including "large tonnage die casting machine casting unit ", The goal is to provide technical support for die-casting enterprise technology upgrades. The development of die-casting technology equipment will help improve the level of die-casting machinery and equipment to improve the quality and technical level of casting and promote the development of casting industry.
