Metal Insert Technology

They are typically made of metal, though wood and non-metallic materials are also used. Depending on the product’s requirements, they are primarily used to enhance strength, fastening, hardness, structural stability, dimensional stability, and wear resistance; to improve electrical conductivity or provide insulation; to reduce plastic consumption; or to improve part precision and support holes for moving components.

Meets High-Strength and Functional Requirements

Enables metal-grade strength, wear resistance, electrical conductivity, thermal conductivity, or high-precision threads in specific areas of plastic parts, combining the lightweight advantages of plastic with the high performance of metal.

High Dimensional Accuracy and Excellent Stability

Inserts ensure precision in critical holes, bushings, and positioning structures; plastic products are less prone to deformation and shrinkage, maintaining stable accuracy over the long term.

Simplified Assembly and Enhanced Production Efficiency

Integration of inserts and plastic parts is achieved in a single injection molding process, eliminating the need for subsequent drilling, tapping, and assembly steps. This makes the process ideal for automated, high-volume production.
