Sheet Metal Fabrication

Description

Sheet metal fabrication is the process of forming and producing parts from a metal sheet. Sheet metal fabrication processes produce highly durable components well-suited for both functional prototypes and end-use production. Our custom sheet metal services offer a cost-effective and on-demand solution for your manufacturing needs. Fabrication services range from low-volume prototyping to high-volume production runs with significant cost savings.

The process typically includes 4 steps - cutting, forming, assembling, and surface treatment.

-Cutting Process

We offer various cutting options with thickness ranged from 1mm to 150mm, this includes oxygen cutting with a maximum thickness capacity of 150mm for carbon steel. We also offer plasma cutting, laser cutting, water jet cutting, wire cutting, shearing, and/or die-cutting, we may also use punching for holes. Laser cutting is the preferred option for cutting sheets, it’s speed and precision guarantees spectacular results. With thicker materials, plasma cutting may be favorable for it’s speed. This method is normally used when the material thickness is over 10mm.

-Forming Process

The forming process typically includes bending, hydraulic press forming with die, punching, and milling. The nature of the parts’ design determines the method used. Deburring is an essential procedure before welding and assembling.

-Assembling

For sheet metal fabrication, the main process of assembling is welding. Fixtures need to be pre-designed and made to ensure a product with no distortion after welding. Some areas require milling after assembling. A set of test gauges are pre-developed for quality inspection,ensuring the complete functionality of the product.

-Surface Treatment

The normal surface treatment process for sheet metal fabrication products include electrophoresis (KTL), powder coating, painting, and zinc plating. For large products like chassis, painting is widely used whereas for middle size parts, the KTL process is preferred. 

For all surface treatment, we offer coating adhesion, thickness, and salt fog tests or, other tests to be conducted upon request.

Anodizing is available with aluminum materials.

Advantages

-Rich Experience

More than 20 years of experience in sheet metal fabrication products development and production, especially to the European and North American markets, with solid understanding of the material, technical and quality standards worldwide.

-Fast Turnaround

Generally, we provide a quotation within 3 working days. Combining the latest manufacturing technologies and facilities, Auwell can provide fast prototypes in just 2 weeks for simple projects.

-Comprehensive Solution Provider

Auwell provides comprehensive services for sheet metal fabrication projects starting from designing,through prototyping,tooling/fixture development, sampling, mass production, and to logistic and post-sale support.

-Rigid QC Policies

The most rigorous quality policy starts from material control, and is followed through to final pre-shipment inspection. 

Material certificates include the mill certificate, 3rd party chemical components, and mechanical property reports, as well as RoHS and REACH reports upon request. Other reports include dimensional reports, surface treatment thickness, and salt fog test reports, etc. We structure our processes, creating Flow Charts and Control Plans before production, making sure all QC processes are in accordance with ISO9001-2015 requirements and drawing specifications.

-Flexible Payment Term

Tooling payments need to be pre-paid. For mass production, we offer flexible payment terms, reasonable credit terms will be given, the client only pays when they are happy with the product they received. For long-term projects, we offer call-off inventory services for fast delivery requirements.
