  When China Lead Die Casting are subjected to heat treatment, their melting point is very low, so they can be easily overheated. The temperature deviation after heating is relatively small. The precision of the thermometer is very high. If the insulation deviation after heating is relatively large, the purpose of strengthening cannot be accomplished. Therefore, it can be seen that controlling the heating temperature of hot lead die castings is the key in the whole process. After many tests, it has been proved that, There is a relationship between the temperature and time during manual operation. If the aging temperature is relatively high, the holding time will be shortened, while if the aging temperature is relatively low, the holding time will be extended. If it is handled in this way, it is very discrete for mass production, which will not control the quality of the final product. However, the use of this way can improve the qualified rate of products and ensure the technological quality of products.

  The advantages of lead die castings include high dimensional accuracy. Generally, it depends on the casting material, and the typical value is 0.1 mm when the size is 2.5 cm, and the error increases by 0.002 mm for every 1 cm increase. Compared with other casting processes, its casting surface is smooth, and the fillet radius is about 1-2.5 microns. It can directly cast internal structures, such as silk sleeves, heating elements and high-strength bearing surfaces. Other advantages include that it can reduce or avoid secondary machining, the production speed is fast, the tensile strength of castings can reach 415 MPa, and metals with high fluidity can be cast.
