Sheet Metal Fabrication Service is a process in which factories or workshops use cutting, stamping, welding, assembly, surface treatment, and other processes to complete the production of workpieces according to requirements. In industrial production, this process may also include drawing design, raw material procurement, quality control, and cargo packaging. , transportation and after-sales service, etc. Below we will introduce it from three aspects: service type, provider, and specific content.

Types of services: OEM and ODM

OEM services are mainly reflected in the fact that buyers need to provide samples and drawings, and service providers only provide production and quality assurance services.

ODM service has one more service content than OEM, which can customize drawings according to the needs of buyers.

Service providers: workshops, factories, and companies

Workshops are smaller versions of factories. They can also complete cutting, stamping, welding, machining, and surface treatment, but they can only provide a small part of the entire service due to space and financial constraints. They are more suitable for customers to choose when customizing one or several sheet metal parts.

The factory has complete and advanced CNC laser cutting machines, punch machines of various capabilities, a variety of welding equipment, CNC processing workshops, and complete quality control centers. They prefer to receive bulk order production and often have minimum order quantities. Larger factories may also be equipped with surface treatment lines, etc. They are more suitable for customers whose monthly demand ranges from hundreds of pieces (heavier sheet metal parts) to tens of thousands (smaller sheet metal parts).

Based on the factory, the company continuously integrates the supply chain to provide other services in addition to the production services that the factory can provide, such as solution customization, process selection, cost accounting, packaging customization, logistics and after-sales services, etc. Choosing a company may help you save more costs.

The specific content of services:

Sheet Metal Cutting: The process of using tools to cut sheet metal into specific shapes.

It has 3 ways:

Thin, less brittle metal sheets are cut into specific shapes by shearing forces, such as with scissors and blanking dies.

Cutting thin and less wear-resistant metal plates into specific shapes by friction, such as abrasive cutting.

Metal plates are cut into specific shapes through high-temperature melting, such as flame cutting, plasma cutting, and laser cutting.

It has multiple uses:

Process the metal plate directly into the shape we want to complete the order. Or provide semi-finished products for the next process.

Sheet metal stamping:

The process of using a mold to change the shape and size of plates, pipes, profiles, etc. under the action of pressure to obtain workpieces.

It has two categories:

Blanking:

Use the shearing force of a mold to remove a specific shape or remove excess from a larger piece of material.

forming:

The shape of the material is changed using a mold to obtain a finished product of a specific shape or a semi-finished product for the next process.

Common forming processes include bending, deep drawing, bulging, stretch bending, twisting, etc.

Sheet metal welding:

It is a process that creates a whole process by melting two parts or the two ends of a part connected to each other at a high temperature and then connecting them or adding some auxiliary materials and then connecting them.

There are three types of welding: pressure welding, fusion welding, and brazing.

The ways to create high temperatures include chemical energy (explosion, flame), electrical energy (arc, resistance, electron beam), light source (laser), and mechanical energy (friction, wave generation).

Welding can complicate an uncomplicated structure to meet the final use requirements.

Surface treatment:

It is a process in which the surface of sheet metal parts is treated mechanically, chemically, electrochemically, mechanically, etc. to change the surface or attach a layer of other substances to protect the interior.

There are many types of surface treatments, you can search for surface treatments on our website and fully understand them.

Assembly:

The process of joining two or more components together by welding, riveting, bolting, and pressing.

Choosing the appropriate assembly method according to the application of sheet metal parts will save us a lot of labor, transportation, and time costs.

QC:

The mechanical and chemical properties of raw materials, semi-finished products, and finished products are tested through various instruments to ensure that they meet the requirements of use.

Other services:

Sheet metal manufacturing service companies often provide additional services such as solution customization, process selection, cost accounting, packaging customization, logistics and after-sales services, etc.

Sheet metal manufacturing services are comprehensively considered to be the process of selecting a suitable sheet metal manufacturer to complete the products we need. A high-quality service provider can help you choose the appropriate process, arrange reasonable production links, and complete higher-quality sheet metal parts at a lower cost. They will also help you save more time and energy through high-quality services.
