THREDED INSERT FOR PLASTIC

A THREDED INSERT FOR PLASTIC is a metal internally threaded component designed to be embedded into a plastic workpiece. Its outer surface typically features knurling, grooves, or barbs. Once installed, it creates a durable threaded hole within the plastic part, making it suitable for products that require repeated fastening and disassembly or improved thread load capacity.

Improves Thread Strength in Plastic Components

The metal internal thread can withstand higher fastening loads, helping reduce the risk of thread stripping, cracking, or hole wear that may occur when screws are driven directly into plastic.

Suitable for Repeated Assembly and Disassembly

Once embedded, the insert provides a stable and durable threaded hole, making it suitable for products that require maintenance, component replacement, or repeated assembly.

Outer Features Provide Anti-Rotation and Pull-Out Resistance

Knurling, grooves, or barbs engage with the surrounding plastic material, increasing resistance to rotation and improving pull-out retention.

Multiple Installation Methods Available

Depending on the plastic material, product structure, and manufacturing process, the insert can be installed by heat staking, ultrasonic insertion, press-fitting, or insert molding.

Suitable for Various Plastic Products

THREDED INSERT FOR PLASTIC products are commonly used in electronic equipment, home appliances, automotive and motorcycle components, medical devices, communication products, enclosures, and industrial plastic assemblies.
