What are the connection technologies in precision sheet metal processing?

2025-07-31

In precision sheet metal fabrication, connection technology is crucial for ensuring structural strength and functionality. It primarily includes the following types and features:

1. Mechanical Connection (Removable)

Bolt/Nut Connection

Assembly is achieved using threaded fasteners. Suitable for applications requiring frequent disassembly, but carries risks such as thread stripping and missed locking.

Variants include self-tapping screws and riveted studs combined with screws.

Pressure Riveting

Using pressure riveted nuts or studs, it is suitable for joining thin sheet metal parts, offering high production efficiency but non-removable.

Pull-Rivet

A pull-rivet gun expands and secures the rivet sleeve, resulting in high connection strength. It is often used in applications where disassembly is not required.

2. Welding Connection (Non-Removable)

Spot Welding

Using double-sided or single-sided electrode pressure welding is economical and efficient, but thermal deformation must be considered.

TIG/MAG Welding

Suitable for three-dimensional welding of thin and thick plates. Heat input must be controlled to avoid deformation.

3. Special Processes

TOX Riveting

This method uses plastic deformation to interlock the materials, eliminating the need for additional parts and providing reliable strength.

Hook-and-Lock Connection

This concealed design, combined with lockwires, saves storage space.

Hinges and Elastic Connections

Living hinges: Adjustable from 30° to 150° for easy assembly.
Elastic fasteners: Quick assembly and disassembly, suitable for lightweight structures.

Summary: Choosing a connection technology requires a comprehensive consideration of removability, cost, and process adaptability. Mechanical connections are suitable for applications with high maintenance requirements, while welding and TOX riveting are more suitable for permanent structures.
