In the injection molding process, ejector pins, as the core components of the ejection mechanism, are responsible for uniformly ejecting the molded product from the mold. A well-designed ejector pin layout not only ensures scratch- and deformation-free products but also reduces mold wear and extends service life.

In injection mold cooling systems, the design of seal grooves is critical to ensuring coolant channel sealing and cooling efficiency. Poorly designed seal grooves can lead to coolant leakage, reduced cooling performance, and even compromise mold lifespan and product quality.

Gas-Assisted Injection Molding (GAIM) is an advanced plastic processing technology that optimizes product structure, reduces material consumption, and improves molding quality by injecting high-pressure gas.

Injection molds are large in volume and mostly made of high-precision steel structures. During ocean transportation, they are prone to moisture, collisions, and vibrations. Inadequate packaging can lead to rust, deformation, or even mold damage.

The sprue not only distributes molten plastic evenly to runners but also directly influences melt temperature, pressure distribution, and mold-filling effectiveness.

Spray painting on injection-molded parts not only enriches the product's appearance but also endows the components with various functions and enhances their performance.

Injection mold mirror polishing refers to progressively grinding and polishing the surface of a mold cavity to achieve a mirror-like finish. This ensures the molded parts have a smooth appearance, easy demolding, and extended mold lifespan.

Demolding difficulties in injection molds are a common issue in the molding process, primarily caused by product design flaws and mold structural factors.

Surface treatments for injection-molded parts can be categorized into three main types: ​​decorative treatments​​, ​​functional treatments​​, and ​​physical/chemical pretreatments​​.

In injection mold design, the layout of venting slots is critical for ensuring efficient air evacuation and improving molding quality. A well-planned venting slot layout not only effectively prevents defects such as air pockets, short shots, and burn marks but also extends mold lifespan and enhances production efficiency.
