The number of wreckers on the market is numerous and the number of people on the brand is dazzling. Looking at it roughly, in fact, they are almost the same, but the wrecker is based on different models and configurations, and the components are not the same. The wrecker is composed of a device, a towing traction device, a hydraulic system, an electronic control system, etc. The four parts listed are the most important part of the wrecker , and these are also the judgments of the wrecker. One of the criteria. In fact, the quality of a wrecker's hydraulic system determines the time it can be used. If the hydraulic system always has problems, then the wrecker must be "sick". The hydraulic system of the wrecker is composed of a fuel tank and an oil pump. Therefore, the oil tank and the oil pump must be selected when purchasing the wrecker. The high - quality and high- precision steel tube material has stronger resistance to bending, and the sealed construction system can ensure high pressure. In bad conditions, the oil cylinder will not leak oil, and the cylinder is selected to ensure the quality of the hydraulic system. In the face of so many brands of vehicles on the market, we must clearly choose the configuration when purchasing ~ 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.
