Introduction: Make the copper liquid pouring into the alloy mold to produce the product under high pressure. Can produce all kinds of brass (such as ZCuZn40PB2, CC770s, etc.) materials.
Advantages : The surface is pretty good; It can produce thin-walled parts and products with complex shapes.
Equipment: IMPRESS-III-DCC280 Cold chamber die-casting machine, can be cast up to 5kg.
Process: Casting - Cleaning casting system - Shot blasting
Introduction：The product was made by the coated sand casting technology (thermal method). Including various no-lead bronze such as C89833,C83600, normal brass such as CC770S,C69300 and so on.
Advantage : Compare with the traditional sand casting, the model is accurate and stable. It has ability to produce some complex shapes products.
Equipment : We have a large specification core shooter, can be cast up to 100kg; And we have a complete casting line.
Process: Coated sand molding - Assembling - Pouring - Cleaning - Cutting and Grinding - Shot blasting
Introduction : Make the copper liquid pouring into the metal mold under the action of gravity for casting. Can produce all kinds of brass (such as ZCuZn40PB2, CC770s, etc.) materials.
Advantages : The surface is low roughness; The mechanical properties of castings are good.
Equipment : IMR Gravity casting machine, can be cast up to 10kg.
Introduction: Heating copper tubes and copper sticks at high temperature and put them into the mold for stamping and forming.
Advantages: high precision of blank size; The material has high density.
Equipment : Equipment: 200-630 ton punch press, can press products up to 200mm.
Process: blanking - heating - red punching - shot blasting - to fly edge
