Different Sizes 18 Inch Polished 5×114.3 Fully Painted Cast Alloy Wheels

When casting, the casting machine is used for casting. The method of low -pressure casting is to press the liquid metal into the cast by using the pressure of the gas, and to solidify the liquid metal knot product by gradually under certain pressure. The premise of the model in the casting machine must be passed the model processing of the model before the casting machine. To deal with the model, first of all, the appearance of the mold should be carefully checked. The mold should be in line with the surface luster and no reverse corner, no sticky aluminum, and cooling system without leakage and blocking. Liu Chang is not damaged. If the problem is found, you must modify the mold in time. After meeting the requirements, you need to preheat the mold in advance. , Can be sprayed on the mold. After spraying, it needs to be grinded with a pre -heating. The temperature reaches 430 ° ℃ to 470 ° ℃ Preheat for one hour before being cast on the machine.
After the mold is on the machine, the first is air -run. We can observe the blanks of the empty operation and check the state of the grinder. According to the needs of different products, adjust the process parameters and the usage of the blasting ducts, enter the corresponding program according to the set conditions, and then turn on the automatic repeated movement for a week to press the mold and maintain the pressure to ensure that the stress in the furnace Followed holes, strain, scratching, stunning injuries, coatings falling off, unexplained the surface of the module on the surface of the module too deeply casting the text to make the text no error, and so on. If all the above requirements are met, the requirements for printing batch numbers for printing batch numbers are that the text must be correct, clearly arranged and neatly arranged, and the position is correct. There is a biased or no axis, and whether there is obvious deformation above the diameter. Finally, the last program of entering the person is performed for X -ray inspection.
