Mechanical Assembly

Mechanical assembly involves using various types of fasteners such as nuts, screws, and bolts to connect multiple parts together. It is ideal for non-permanent connections or situations requiring adjustments and routine maintenance.

Welding

Welding is a manufacturing process used to join metals or other thermoplastic materials by heating, high temperature, or high pressure.

Riveting

Riveting entails forming the end of a metal pin, rod, or bolt to create a head, securing two metal objects together by applying concentrated force or using a nail to push them together.

The choice of assembly method depends on factors such as cost, permanence requirements, the type of metal parts, and the application's strength and durability needs.

At Dongkun Metal, we provide comprehensive sheet metal manufacturing and assembly services, handling a wide range of metal assembly requirements with accuracy and durability.
