In order to improve the quality of plastic machining molds, minimize mold quality complaints
Discussed the influence of poor exhaust and template expansion mold deformation on the product, proposed an idea of controlling the injection pressure distribution by changing the number and distribution of gates, and introduced an example of a way to eliminate injection molding by preset compressed air space The method of mold template expansion and deformation.
Copper has good electrical and thermal conductivity, sufficient corrosion resistance in the atmosphere and many media, and has a series of characteristics such as sufficient strength and good plasticity.
The aging temperature of beryllium bronze is related to the content of Be, and alloys containing Be less than 2.1% are suitable for aging treatment.
It is not possible to harden or increase its strength by heat treatment. It can only be improved by work-hardening methods of cold working.
Beryllium copper is a supersaturated solid solution copper-based alloy. It is a non-ferrous alloy with excellent combination of mechanical functions, physical properties, chemical functions and corrosion resistance.
The micro-resistance spot welding method was used to successfully achieve the connection of 0.1 mm thick bronze pieces.
Beryllium copper is a copper matrix alloy material with beryllium as the main element. Its scope of application uses beryllium copper materials only under the requirements of high thermal conductivity, high hardness, and high wear resistance.
In order to reduce the segregation of alloy components, overcome the defects of shrinkage pores, and improve the comprehensive strength level of beryllium aluminum alloys, powder metallurgy is usually used in engineering to prepare beryllium aluminum alloys.
After solution treatment and aging treatment, the strength can reach 1250-1500MPa (1250-1500 kg).
