 Hello! 
 Thank you for taking the taking the time to understand the Democratic Secretary, our company is a Taiwan-owned enterprises, with forty years of production history. Professional production of high efficiency mold material (beryllium copper, CA-2H copper alloy) of the manufacturers. 
 Use of beryllium copper features: First, the most important feature is the high temperature 1200 ° or so, low coefficient of thermal expansion accounts, corrosion resistance, smooth. Second, not leaving because of high temperature or extrusion die deformation or cracking. Third, the mold inserts, mold material, thermal conductivity, fast, good cooling of steel, cast iron, 20 times. 
 CA-2H copper alloy use and characteristics: First, the main material for drawing dies, bending mold material, stamping mold material, has been widely used in the automotive industry. Stainless steel sinks, pot and other tensile modulus material first. CA-2H copper alloy hardness up (HRC55 °), no heat, fast heat conductivity, friction coefficient is small, no drawing, drawing marks. Reduce the rate of making bad stretch, with a pass rate of 99.5%, increase work efficiency by 30% -45% and reduce costs. Second, CA-2H can replace beryllium copper alloy brass inserts plastic mold industry. As fast thermal conductivity of the material, cooling and good resistance to corrosion, control shrinkage after molding to improve the dimensional stability, which can effectively speed up the mold and extend die life time. Its efficiency is only 2% worse than beryllium copper, beryllium copper, but a lot cheaper (a bronze in the half), the plastic mold inserts in the economic environment of high quality mold material, which provides trial.
