How to make a Crate Mould with high-speed performance?

  Choose the appropriate mold base steel and mold main steel. You must choose the right steel or material for durable mold parts.

  Correctly quench each steel plate and control its hardness. You can't make it too hard.

  The moving area or guiding system of the crate mold must be very precisely machined. Any hands working on it are unacceptable.

  If the plastic crates are single-use, some molding companies will use recycled materials for injection. Then, we must consider these two points. A. How to ensure that small iron pieces and pebbles will not damage the cavity and core. B. How to prevent small iron pieces and pebbles from entering the cavity? How to make a Crate Mould with high-speed performance?

  A good plastic filling system requires a very special hot runner system.

  You need to achieve the best cooling effect. For durable Crate Mould, you need to use molds in the molding area and have an excellent cooling water channel design; for single-use crates, you need to use excellent Cooling performance of tempered steel cooling system design.

  You need to use a high-speed injection molding machine to run it, and the screw RPM should be greater than 350. Worldwide, most box manufacturers are now using accumulators to increase the melt and injection speed.

  The design of the Crate Mould is also very important. It is best to use a mechanical system for ejection on the turnover box mold so that the ejection action can be made when the mold is opened. Of course, maybe your machine can work with two hydraulic systems at the same time, and then eject when the mold is opened.

  For all types of molds, high-speed operation is based on precision-machined molds, and the moving parts have precise guidance...Otherwise, the high-speed performance of the mold will be impossible.

  Drawer Mould is also our product, welcome to consult and purchase.
