Product Details
The silica sol process is not only suitable for the casting of various types and alloys, but also produces Alloy Steel Investment Casting for Forklift Parts with higher dimensional accuracy and surface quality than other casting methods, and even for other castings which are difficult to cast and are complex, high-temperature resistant, and not easily processed. Forklift Parts Investment Casting can be casted using investment castings. 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 dipping slurry process, most of the suppliers adopt water glass technics in domestic area, but we adopt compound technics or silica sol technics. 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 castings much more stable, the internal tissues much more well-proportioned. 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. In smelt process, we use middle frequency furnace, avoiding the emergence of the oxide; in molten steel control part, we use Germany-imported direct reading spectrometer machine, assuring its quality before the molten steel out of the furnace.During this process we use ERP production and management software to get the feedback information. In shell-knock out process,we have special machines,which can decrease the hitting and knocking, easily made by manual shell knocking out. In shot-blasting process, we have crawler-type and hanging shot-blasting m
