In the injection molding process, short shots refer to the failure of the molten plastic to completely fill the mold cavity, resulting in missing parts or incomplete molded parts. This defect not only affects the appearance of the product, but may also affect its functionality and assembly accuracy. This article will briefly introduce the causes and prevention methods of short shot in injection molding.

During the injection molding process, flash (also called flash or burrs) refers to the excess plastic that appears at the edge or seam of the molded part. This not only affects the appearance of the product, but may also affect its functionality and assembly accuracy.This article will give you a brief introduction to the causes of flash prevention methods.

Injection molding is an efficient manufacturing process widely used in the production of plastic parts. However, in the actual production process, various defects may occur, which not only affect the appearance of the product, but also its functionality. 

Shrinkage marks are one of the common problems that affect product appearance and quality in injection molding. Shrinkage marks usually appear as depressions or uneven lines on the surface of the product, which may lead to reduced product functionality in severe cases. This article will explore the causes of shrinkage marks and their solutions to help manufacturers improve product quality.

The runner system directs molten plastic from the injection machine’s nozzle into the mold cavity. Its role is to ensure smooth and orderly filling of the cavity and transmit injection pressure to obtain well-structured plastic parts during filling and solidification.

An ejector pin is a cylindrical component used in injection molding to remove the finished parts from the mold core. It is usually made of steel alloy and built for high pressures and repetitive motion durability.

In the injection molding process, the gate (also known as the feed port or injection port) is an important component that connects the injection molding machine with the mold, playing a crucial role. The design and configuration of the gate directly affect the flow of plastic, filling efficiency, and the quality of the final product. This article will delve into the function, types, and importance of the gate in injection molds.

In the injection molding industry, the mold base (also known as the mold frame or mold base) is an indispensable and important component in mold design and manufacturing. The mold base not only provides necessary support and stability for the mold, but also plays a key role in the entire injection molding process.
