High beryllium copper is a supersaturated solid solution copper alloy, is non-ferrous alloy with good mechanical properties, physical properties, chemical properties and good corrosion resistance together. After solution and aging treatment, it have very high strength limit, elastic limit, yield strength and fatigue limit as special steel have, and at the same time have a high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep rand corrosion esistance.

cakes and other similar products are mainly used in plastic injection molding industry, facing all kinds of plastic mold manufacturer.

The advantage:((1) Long life of beryllium copper mold

For manufacturers, the expected life of the mold is very important. On the gound of meeting the requirements of strength and hardness, beryllium copper’s resistance to thermal stress is much stronger than steel mold, the insensitivity to mold temperature’s stress can greatly improve the life of the mold, which both to ensure the continuity of production, and to reduce the cost. From this point, the long life of beryllium copper is compelling.

(2) Good thermal conductivity properties of beryllium copper

Beryllium copper's high thermal properties can help to control the plastics processing mold’s temperature, easier to control the molding cycle, and can ensure the temperature uniformity of the mold wall. Compared with the steel, beryllium copper’s molding cycle is much shorter, the average temperature of the mold can be reduced about 20%. When the difference between the average temperature of the mold and the average off touch the wall’s temperature is small (for example, mold parts can not easily be cooled in the case) , use the beryllium copper mold material, the cooling time can be reduced by 40% and the mold wall temperature is only reduced by 15%. These features will bring several benefits to the mold manufacturers using this material: shorting the molding cycle time, increasing the productivity; Good temperature uniformity for mold wall, improving product quality; Reducing the usage of cooling ducts, simplifying the mold structure; Increasing the material’s temperature, thereby reducing the wall’s thickness of small products, reducing product costs.

(3) Excellent surface quality of beryllium copper

Beryllium copper is very suitable for surface finishing, plating can be directly processed, and as the adhesion performance is very good, polishing can be very easy. This enables the surface of the product surface to be more smooth, detailed, consistent to the requirements of aesthetics and precision.

(4) High rate of heat penetration for beryllium copper

In addition to thermal conductivity, the thermal transmittance of the mold material also do a very important impact on the plastic products. The use of beryllium copper mold, can eliminate the signs of overheating. If the heat penetration is low, the distal end region of the mold wall contact temperature will be higher, so that the mold temperature difference will be large, and in some extreme cases, it may cause changes in the temperature region, extending from the end of the plastic to the other end , so the sink marks might appear in the overheated region.

The advantages of our products:(1) Price advantage. We are factory directly selling, bypassing a middleman, the profits will be returned to the second class distributors and end customers, to ensure most competitive price.

(2) Quality advantage. Company producing management personnels have many years of experience in producing and researching the beryllium copper. They are trained by the company on the own, have a high degree of understanding and production experience. (3) Fast delivery. Efficient production management and convenient transportation ensured the fast shipping speed.
