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.

The Heavy Truck Hao Hao heavy truck that debuted at the business annual meeting at the end of last year, after more than half a year of actual operation verification, was finally launched today in Nanjing (July 21).
According to Yu Youde, deputy general manager of CNHTC at the opening ceremony, CNHTC Haohe Heavy Duty Trucks is a company that has concentrated on the advantages of Mercedes-Benz, German MAN, and CNHTC's own technology. New commercial vehicle. "The Haohe heavy trucks use the Mercedes-Benz cab, the chassis of the German Mann technology assembly, and have been optimized based on the many years of technological and market advantages of China National Heavy Duty Truck. It is China National Heavy Duty Truck Group's adjustment of the product structure in response to market changes. The launch of the first, truly lightweight model, with economic, security, reliability and other major advantages." Yu Youde said.
According to Cao Changxin, general manager of CNHTC Jining Commercial Vehicle Co., Ltd., which produces Haohe heavy trucks, the first few days (July 15th) of Haohao's launching ceremony, in order to finally verify the economical efficiency of Haoshao, they convened around Nanjing. Dozens of logistics companies elected nearly a hundred heavy truck drivers and held a "Hao Hao heavy truck fuel-saving competition." "The results of the competition show that under the comprehensive road conditions, with the Haoying double bridge tractor, the contestants achieved good results within 13 liters of fuel consumption of 100 kilometers." Cao Changxin stressed that such good results are rare in the country, at the same time, This is also the best proof that the Haohe heavy truck can achieve 15% more fuel efficiency than the domestic same type of product after matching experiments with engines, transmissions, drive axles, and power transmission systems.
In addition, Cao Changxin also said that although at the beginning of the listing, many users were full of expectations for Haohe heavy trucks, dealers have been urging them to go public soon. “But we are very cautious. We have carried out more than 60 quality optimization enhancements for the vehicles after verification, and even opted to re-evaluate the plans. We postpone the time-to-market again and again until the group level experts have passed the unanimous acceptance. The product can be listed." Cao Changxin said.
