Here are some key points of Crate Mould
Adding Becu to local steel can achieve the best cooling effect and greatly shorten the molding cycle.
How to make a good Plastic fruit Vegetable Crate Mould?
In the next stage, the choice of steel determines the life of Crate Mould. The most commonly used steel for HDPE crates and pallets is China P20 for the core and cavity and C45 steel for the mould base. The hardness of the steel is 35 ~38 HRC. With the use of China P20 one can run for at least 500,000shots without any glitches.To make a good crate mould, you need to know the technical points and the quality points of a crate mould as follows.

For the mould, we pay more attention to the crate mould cooling system design. A good plastic filling system requires a special hot runner system to assist with molding to ensure optimal cooling. In order to produce a durable mold, the cooling water path on the largest forming surface of the mold must be optimized, and the tempered steel must be used with the excellent cooling water circuit design. In addition, the air venting system at the handle of the trunk is also the focus of our design. When the container is under load, the handle at both ends is the key point. If the two handles on the mold are not vented properly, obvious seams will be left and the product will be easily damaged.
In terms of mould processing, we select the appropriate materials and hardness of the mould frame, core and cavity, as well as the appropriate standard parts of the mold, so as to avoid problems in the process of use. For the friction in the crate mould, and its guide part, we must pay attention to its processing. In addition, manual operation is not allowed, so as not to affect the processing effect and quality, thereby affecting the quality of the turnover box.
With these processing techniques, our plastic crates moulds have a fast forming speed and good molding results. In addition, we will simulate the real production environment before shipment, and run the mold for 2 hours to show you the mass production process.
