Treatment of raw materials, the actual production will be different
Petroleum parts investment casting is one branch of Alloy Steel Precision Casting, which is widely used in petroleum markets. Casting for petroleum parts adopts lost wax casting, also called investment casting.
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 heat treatment process,we use electric furnace,and adopt double-temperature control in order to heat the products equally.As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.
Our petroleum parts investment cast has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The investment casting of petroleum parts can be made completely based on your specifications such as drawing, design, sample etc.
