The July Purchasing Managers' Index verified the predictions made by industry insiders that sales in all sub-sectors of China's machinery manufacturing industry will turn positive at the beginning of the year. According to analysts' opinions, China's construction machinery will gradually get out of relying solely on capacity expansion to bring about growth, and will gradually transition to The stages of product upgrades and added value enhancements. The specific performance is that the product goes to the high end; at the same time, it enters the financial leasing and remanufacturing business with higher and more stable profitability and less periodicity; at the same time, the extension of engineering machinery products is continuously expanding.
Agricultural machinery parts investment casting is one branch of alloy steel precision casting, which is widely used in agricultural machinery markets. Casting of agricultural machinery 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 agricultural machinery parts casting 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 cast of agricultural machinery parts can be made completely based on your specifications such as drawing, design, sample etc.
