Architectural Hardware Precision Castings

 We are a high quality Architectural Hardware Precision Castings and steel foundry for stainless, carbon, and tool steel materials; we also work with bronze, aluminum, and other alloy and specialty materials. We provide low- and high-volumePrecision Castings for Architectural Hardwares, as well as rapid prototyping services.  In wax pattern process, we mix stearic acid and paraffin wax in wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small.     In shell making, we adopt automatic sand-covering production line, which was invented under the guidance of our general manager. The indoor temperature was controlled by air-conditions, keeping the temperature at  24℃±1℃, which can make the Casts of Architectural Hardwares much more stable, the internal tissues much more well-proportioned.  In shell hardening process, we use aluminium chloride to harden the shell. This can make the shell so hard that it can`t be distorted, at the same time the bug which the Architectural Hardware Casts may have will be decreased. If there are letters or numbers in it,they will be much clearer.  In dewaxing process, about 95% of the castings suppliers adopt the original water dewaxing technics, but we using the advanced steam dewaxing technics, which we are very proud of. This can effectively avoid the air-hole and sand-hole, making the casting look much nicer.
