The shape and size of the gate have a great influence on the quality of the product.

The function of the door is:

A. Control the speed of material flow:

B. The melt in this area solidifies prematurely and prevents reflux when injected:

C. Increase temperature by cutting through the melt, thereby reducing apparent viscosity and increasing fluidity:

D. Easy separation of products from the pouring system.

The design of the gate shape, size and position depends on the performance of the plastic, the size and structure of the product. The General Gate section shape is rectangular or circular, the section area is small, the length is short. This is not only based on the above effects, but also because small doors are more likely to get bigger and the doors are difficult to shrink. The gate position should generally be selected in the thickest part of the product, without affecting the appearance. The design of the gate size should take into account the performance of the plastic melt. Cavity is the space in which plastic products are formed in the mold. The parts used to form the cavity are collectively referred to as molded parts. Each forming part usually has a special name. The forming part that forms the shape of the product is called the die (also known as the Die), and the concave mold forms the internal shape of the product.
