1. How to make a pair of plastic fruit crate mold have a long service life?
First of all, choose the right steel for the plastic fruit crate mold mold base and plastic fruit crate mold core cavity part. For example: to produce a pair of plastic fruit crate molds, one must use pre-hardened steel with a hardness higher than 33 as the mold base, and then select the appropriate mold standard parts.
Secondly, the hardness of each piece of steel must be well controlled and not too hard.
Then, the friction and guide parts of the plastic fruit crate mold must be finished without any manual work.
Finally, some plastic fruit crate molds will use recycled materials for mold injection. 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 cavity.
2. How to inject plastic fruit crate mold at high speed?
A good plastic material filling system requires a special hot runner system to assist molding, because the production of durable plastic fruit crate requires low melt index HDPE material, such as a melt index of 4 or 6 and so on.
3. Make sure the cooling system achieves the best effect. To produce a durable plastic fruit crate mold, the cooling water path design must be optimized on the largest molding surface of the mold. For the production of plastic fruit crate molds, quenched and tempered steel must be used with an excellent cooling water design.
4,. The design of the plastic fruit crate mold is also very important. The ejection method of the mold is preferably designed to be automatically ejected by a mechanical system, so that the ejection action can be completed when the mold is opened. Of course, if the injection molding machine can be equipped with 2 hydraulic drives to cooperate with the machine to automatically eject, the ejection action during mold opening can be smoother.
The mold must be high-precision, and the accessories must have an accurate guiding function, otherwise the mold cannot have high-speed operation performance.
