Chốt làm kín LSR cho miếng lót kim loại của thanh chống cửa sau ô tô

The Automotive Tailgate Strut Metal Insert LSR Sealing Pin is a precision overmolded sealing component designed for automotive tailgate struts, trunk lift supports, electric tailgate systems, and related motion-control assemblies.

This component combines a rigid metal insert with liquid silicone rubber through an LSR overmolding process. The metal insert provides mechanical strength, dimensional stability, and assembly positioning, while the LSR silicone area delivers sealing, cushioning, vibration reduction, and long-term functional reliability.

It is suitable for compact automotive mechanisms where metal strength and flexible sealing performance are required in one integrated component.

Các tính năng chính

Metal Insert + LSR Integrated Structure

The product is made by placing the metal insert into the mold and directly overmolding LSR silicone onto the required sealing areas. This creates a stable metal-silicone integrated part.

Hiệu suất làm kín đáng tin cậy

The LSR silicone section helps provide sealing and flexible contact inside the tailgate strut or rod assembly, reducing the risk of leakage, looseness, vibration, and abnormal noise.

Strong Mechanical Support

The metal insert offers high strength and accurate positioning, making the component suitable for automotive assemblies that require repeated movement and long-term durability.

Compact Precision Design

The small cylindrical structure is suitable for limited internal spaces inside automotive tailgate struts, gas springs, lift rods, and electric tailgate mechanisms.

Good Durability for Automotive Use

LSR silicone offers good elasticity, aging resistance, temperature stability, and compression performance, supporting stable use in automotive working environments.

Quy trình sản xuất

The product is manufactured using a metal insert LSR overmolding process.

First, the metal pin or insert is precision-machined according to the required size and surface condition. Then the metal insert is placed into the LSR mold. Liquid silicone rubber is injected and vulcanized around the specified area of the metal insert, forming an integrated sealing structure.

This process allows the metal and silicone parts to be combined into one functional component, reducing separate assembly steps and improving dimensional consistency.

Advantages of Metal Insert LSR Overmolding

Metal insert LSR overmolding is suitable for automotive parts that require both strength and sealing performance.

Compared with separately assembled rubber seals, overmolded LSR parts can provide better positioning stability and reduce the risk of missing, shifting, or loose sealing components during assembly. The metal insert ensures structural reliability, while the silicone section provides elastic sealing and cushioning performance.

This makes the product especially suitable for internal automotive components exposed to vibration, repeated movement, compression, and long-term mechanical operation.
