We all know that there are many parts in automobiles, and most of the parts are made from molds, just like the automobile cooling water tank made by auto radiator tank plastic mould . So how do we make the service life of a pair of molds longer?
First, select the right steel material for the mold base and mold core cavity. For example: to produce a pair of turnover box molds with four out of four, you must use pre-hardened steel with a hardness higher than 33 as the mold base, and then select suitable standard mold parts.
Secondly, the hardness of each piece of steel must be controlled, not too hard.
Then, the friction and guiding parts of the turnover box mold must be finished, and no manual work can be used.
Finally, some mold companies will use recycled materials for injection molding. At this time, we must consider the following two points: A. How to ensure that small impurities in the plastic do not damage the core and cavity; B. How to prevent impurities from entering the cavity.
Of course, in addition to this, the necessary maintenance and maintenance are indispensable. If you want the mold to have a long service life, you must give the mold the best protection.
