Based on the power source, the core-pulling mechanisms in plastic injection molds can be primarily classified into manual, electric, and hydraulic or pneumatic types, each with its unique characteristics and application scenarios.

In the process of injection molding, dimensional deviations in plastic parts are a common issue. The size of plastic parts is typically influenced by factors such as the type of plastic material (including additives), the mold shrinkage index, and the injection molding conditions.

Gas marks are a common and troublesome issue in injection molding. They manifest as tree-like, wave-shaped scratches on the surface of plastic parts, centered around the gate, significantly affecting the product's aesthetics and quality.

Did you know that in the world of plastic mold processing, we sometimes encounter those annoying issues like sink marks? Don't worry, today we're going to dive into the reasons behind them and how to solve them!

This is a serious problem that urgently needs to be addressed. In recent years, although significant progress has been made in domestic plastic injection mold technology, there is still a certain gap compared to foreign manufacturing standards. Various factors can lead to mold cracking during operation.
