In the design and manufacturing of plastic molds (injection molds), certain component interfaces require clearance (relief) to prevent interference, friction, and jamming, or to ensure proper mold opening/closing and molding functionality.

The size and length of the gate are critical parameters in injection mold design, significantly influencing the injection molding process and the quality of the final product.

Mold shrinkage rate refers to the percentage of dimensional contraction in plastic products after removal from the mold, caused by cooling and internal stress release.

Injection mold coatings (also known as mold surface treatments or surface coatings) are widely used to enhance mold performance and lifespan. Their key benefits include improved wear resistance, corrosion resistance, demolding efficiency, thermal stability, and more.

A comprehensive approach encompassing design, material selection, pretreatment, injection parameters, and mold structure optimization is required to achieve flawless bonding between plastic and metal inserts in insert molding.

The design of holes in injection molded products is a critical aspect that affects product functionality, mold design, molding processes, and product strength.

Degradable plastics are materials capable of breaking down into water, carbon dioxide (or methane), and biomass under specific environmental conditions.

Flash (also known as burrs or excess material) in injection molded products typically occurs when molten material leaks through the mold parting line, sliders, or gates.

TPE overmolding injection molding (also known as TPE overmolding) is a widely used process that directly bonds thermoplastic elastomers (TPE) with a substrate material (e.g., plastic, metal, or composite) via injection molding.

Transparent injection-molded products demand exceptional attention to multiple aspects during processing due to their stringent requirements for surface quality, including material selection, equipment adjustment, mold design, and process control.
