Hammer head jamming. In casting, if the phenomenon of hammer head jamming occurs, it will directly lead to the suspension of the casting process. Therefore, in the casting process, the casting workers should often measure the temperature of the hammer head and cylinder, to avoid the high temperature caused by the hammer head jammed. Not only that, the choice of alloy materials without impurities, to prevent impurities stuck in the hammer head, but also can effectively avoid the hammer head stuck.

Stainless steel precision casting problems and solutions

One. Hammer head jamming. In casting, if the phenomenon of hammer head jamming occurs, it will directly lead to the suspension of the casting process. Therefore, in the casting process, the casting workers should often measure the temperature of the hammer head and cylinder, to avoid the high temperature caused by the hammer head jammed. Not only that, the choice of alloy materials without impurities, to prevent impurities stuck in the hammer head, but also can effectively avoid the hammer head stuck.

Second, the pressure injection head stuck in the goose neck. When the situation occurs, you need to wait for the temperature of the equipment to reduce to room temperature state, try to turn the hammer head, if you can not turn, then you need to replace the cylinder, and then take out the hammer head. However, directly changing the material pot will be much faster than this method.

Third, easy to crack when die-casting thin-walled products. When this situation occurs, first of all, we should consider whether there is a problem with material selection, and secondly, we should check whether the mold opening and process parameters are set appropriately. In the casting, try to ensure that the proportion of scrap does not exceed 30%, stay in the mold time should also be as short as possible.

Fourth, the material is hard, the tool is easy to wear. Casting material is hard, in production, the tool is vulnerable to damage, not only will damage the casting tool, but also extend the casting parts delivery cycle. Casting workers at work, you can use the original material ratios, while using a higher hardness of the gem blade.

Fifth, the aluminum die-casting parts have black spots when polishing. At this time, you can reduce the concentration of spraying agent or change to another spraying agent, while lengthening the blowing time after spraying can also effectively solve this casting defect.

Six, metal splash. In die-casting, sometimes the phenomenon of metal spatter. To solve this problem, what is the solution? Reinstall the mold; increase the clamping force, adjust the die-casting machine, so that the movable and fixed mold mounting plate keep parallel to each other; increase the support plate on the movable mold, increase the rigidity of the set plate.
