The crate mould is with reasonable structure, reliable operation, easy molding process control, crate quality assurance.

Using hotrunner system technology to improve the quality of plastic parts, reduce production costs and save time.

Currently,the crate applied to the field of logistics, such as beer crates, milk crates, food boxes and all kinds of cargo turnover box used in workshop is basically made of plastic.

Pipe Fitting Mould

Plastic crate owns the features like anti-bending, anti-aging,heavy loading, tensile resistant, compression resistant, tearing resistant, high temperature resistant and so on.

Often ,these Crate Dimensions are large and also require good mechanical properties, low temperature performance and durability.

To meet these requirements, HDPE is used as a raw material and design a number of criss-crossing ribs on the outer surface and the bottom of the plastic crates, in order to increase its strength and stiffness.

For good plastic injection molding, on crate mould structure design, the crate mould often adopt 4 or 6 hotrunner drops gate (or 3 plates crate mold)due to the large size ,complex shapes; due to four side walls with a lots of ribs perpendicular to the turnover box mold open direction ,4 sliders are need to form those ribs and make the crate release away from the mold.
