  • Aluminum Alloy Series
  • Aluminum Alloy SeriesThe aluminum alloy casting can be divided into gravity casting, low pressure casting and high-pressure die casting. Aluminum die castings with sand core usually adopt gravity casting and low pressure casting. The precision machined products do not allow the existence of sand core....
  • Copper Alloy Series
  • Copper Alloy SeriesCopper alloy casting may be influenced by some factors, such as tensile and compressive strength, wear qualities when subjected to metal-to-metal contact, machinability, thermal and electrical conductivity, appearance and corrosion resistance. These factors should take into consideration for maximizing the precision machined products performance....
  • Forging Material Series
  • Forging Material SeriesPrecision forging technology is a combination of hot forging and cold forging process. It permits to manufacture high-strength components with complex functional elements. They deliver a high surface quality with close dimensional tolerances....
  • Iron Casting Series
  • Iron Casting SeriesIron castings are typically used for the energy (oil & gas), automotive, agriculture, valve and pump industries. As a raw material iron is much cheaper than stainless steel because of the high cost of the nickel and chrome added to steel....
  • Stainless Steel Series
  • Stainless Steel SeriesStainless steel castings are primarily used for corrosion resistance and abrasion resistance without plating or machining. These precision machined products are typically applied to food preparation and marine industries. Stainless steel investment casting can be polished to a mirror finish for the ultimate in corrosion resistance, even in salty marine conditions....

Application of Our Precision Machined Products
Precision machining process can be used in many fields, such as military, high-speed rail, ship, engineering machinery, pump, semiconductor equipment, wind power, power station and electrical equipment as well as medical machinery.

Process of Precision Machined Products
This process starts by using computer-aided manufacturing which utilizes software tools to assist engineering and machinists. Following the creation of a computer-aided design, the machining progress has four stages: roughing, semi-finishing, finishing and contour milling.
During roughing, the raw stock is cut roughly to the shape of the final model. In the semi-finishing process, the part is cut to a nearer shape of the model. At the finishing stage, it involves a slow pass across the material in very fine steps. Finally, during the contour milling stage, the work piece is rotated. This precision machining process can manufacture the precision machined products which have excellent surface finish with dimensional accuracy.
