Nowadays, more and more plastic mold manufacturers have begun to use beryllium copper mold materials. Among many metal materials, what makes beryllium copper more and more popular? What kind of characteristics make it stand out? Maybe many people don’t know what kind of metal beryllium copper is, so the editor will tell you what the characteristics of beryllium copper in industrial production are different from other metal materials. .
First of all, beryllium copper has sufficient hardness and strength: the proof of theory and practice – the hardness of beryllium copper can reach the hardness, strength and high thermal conductivity suitable for plastic mold manufacturing requirements at HRC36-42, and the machining is simple and convenient. The characteristics of long service life of the mold and the saving of development and production cycle, etc.
Secondly, beryllium copper has good thermal conductivity: the thermal conductivity of beryllium copper material is conducive to controlling the temperature of plastic processing molds, making it easier to control the molding cycle, and at the same time ensuring the uniformity of mold wall temperature; using beryllium copper mold materials, cooling Time can be reduced by 40%. The molding cycle is shortened, the productivity is increased, the mold wall temperature uniformity is good, and the quality of the drawn product is improved; the material temperature can be increased, thereby reducing the wall thickness of the product and reducing the cost of the product.
Finally, the beryllium copper mold has a long service life: when the strength and hardness of beryllium copper meet the requirements, the insensitivity of beryllium copper to mold temperature stress can greatly improve the service life of the mold. The yield strength, elastic modulus, thermal conductivity and temperature expansion coefficient of beryllium copper should be considered. The resistance of beryllium copper to thermal stress is much stronger than that of die steel.
These properties are all favorable factors for cost saving and improving product production quality and production efficiency for mold manufacturing. In comparison with steel molds, the superior performance of beryllium copper has become a choice for manufacturers to abandon other metal materials and choose it. Key factor.
