The application of beryllium copper plastic mold manufacturing

When it comes to red copper everyone may not be unfamiliar, plastic mold manufacturing copper is only exists in the form of machining tools, eventually will not show in the form of spare parts in the mold, and beryllium copper is precisely on some performance better than the general steel, even can replace it. Many don't know about plastic mould making friends don't understand, the mould is not steel, how can use copper? Now more and more of the plastic mold manufacturing enterprises begin to use beryllium copper mold material, and a rising trend, the reasons for this phenomenon is what? Is, of course, beryllium copper hardness, strength, thermal conductivity, wear resistance and long service life, such as performance, through this article, we will be together and understand the use of beryllium copper in plastic mold manufacturing in the reason in detail. Beryllium copper features to talk about it in the application of plastic mold manufacturing: 1. Good heat conductivity characteristics: thermal conductivity characteristics of beryllium copper material is helpful to control the temperature of the mold in injection molding processing, it will be easier to control the molding cycle, at the same time can guarantee the uniformity of the mold wall temperature; If compared with steel, beryllium copper molding cycle is much smaller, the average temperature of the mold can be reduced about 20%, when the average touched off temperature difference between the average wall temperature and die is small ( For example, in the case of mold parts is not easy to be cooling) Use beryllium copper mold material, cooling can reduce 40% of the time. And the mold wall temperature is only down 15%; The characteristics of beryllium copper mold material to use this material mould manufacturer several benefits: molding cycle is shortened, productivity; The mold wall temperature uniformity is good, improve the quality of plastic products; Mold structure is simplified, because the cooling pipe; Can improve the material temperature, thus reduce the wall thickness products, reduce the cost of the products. 2. Enough stiffness and strength, after many times of experiment, the engineer can find out and grasp the beryllium copper best precipitation precipitation hardening of conditions and the optimum condition and beryllium copper mass properties ( This is beryllium copper begins with a formal product application in the prelude to market) ； Beryllium copper material used in plastic mould manufacturing before it needs after many cycles test to the end the best conforms to the manufacturing and processing of physical properties and chemical composition to determine down; Theory and practice of certificate & ndash; The hardness of beryllium copper in HRC36 - Suitable for plastic mould manufacturing requirements can be achieved when 42 hardness, high strength, thermal conductivity, simple machining convenience, long service life of mould features, and saves the development and production cycle, etc. 3. Mould service life is long: budget mould cost and the continuity of production, the service life of mould is expected for manufacturers is very important, in the strength and hardness of the beryllium copper under the condition of meet the requirements, beryllium copper insensitivity of mold temperature stress can greatly improve the service life of the mold, before the use of beryllium copper mold material is determined also want to consider beryllium copper yield strength, elastic modulus and the expansion coefficient of thermal conductivity and temperature. Beryllium copper resistance of thermal stress is far better than steel, at this point the service life of beryllium copper is compelling! 4. Excellent surface quality: beryllium copper is very suitable for surface finishing, electroplating processing can be directly, and viscosity can be very good, beryllium copper polishing treatment is also very easy. 5. Heat penetration rate is high, in addition to pull performance guide temperature, mould materials heat penetration rate's influence on the plastic products are quite important, in the use of beryllium copper mold, can eliminate overheat, if heat penetration rate is low, the mold wall distal area of the contact temperature would be higher, this will make the mold temperature increased, in extreme cases will cause the regional temperature change from one end of the plastic products of shrink mark extends to the other side of the overheating of the product. Comprehensive the above points, it is not difficult to find that, at present the beryllium copper in plastic mold manufacturing does exist in some steel amounted to less than the material performance, so the beryllium copper is widely used in plastic mould manufacturing industry. But small make up also want to remind you that use beryllium copper compared to steel also has some disadvantages, such as beryllium copper is expensive, compared to machining steel clamping more difficult, the machining accuracy can not reach the precision of steel material,,, the manufacture of plastic mold, in the case of thin wall or glue a too deep, usually just some special characteristics part chooses the beryllium copper insert, beryllium copper, good thermal performance, rapid cooling speed heat is developed to get incisively and vividly, and the qualified strength, hardness and service life of it is the first condition.
