Sheet Metal Fabrication Process & Capabilities

We focus on high precision sheet metal fabrication in diverse industries. Our high-technology methods facilitate quick, dependable, and affordable solutions since the initial stage of prototyping all the way to high-volume production. Some of the services that we provide include laser cutting, punching, bending, welding, stamping, and assembly, all of which are directed towards the provision of the highest quality parts in the most accurate and fastest possible manner.

激光切割

Lewei Precision involves the cutting of sheet metal with high powered lasers to cut with precision and produce intricate patterns and tight tolerances. Laser cutting is ideal to use in the case of flat-sheet designs, complex features, and minimizes wastage of materials and quality, so it is ideal in prototyping or any large run of production.

弯曲

With press brakes and high end forming machines, Lewei Precision shapes sheet metal into accurate angles and intricate shapes. The service supports many material thicknesses, and provides precise bends of anything including simple design and complex design.

焊接

Our welding services are of high quality, such as TIG and MIG welding, which we are offering to join sheet metal components. Such methods guarantee a high level of strength and durability of joints in custom assemblies which provide the structural integrity needed in sophisticated designs and end-use applications.

打孔

In our punching service, we use high-tech punch equipment to cut the correct holes, slots and shapes on sheet metal. This process also guarantees high accuracy both in small-lot and large scale output, and delivers reliable and economical outcomes to the different applications.

Assembly and Finishing

We provide 100 percent assembly and finishing of sheet metals. Be it in post processing, such as polishing or coating or a combination of various parts into a finished product we offer solutions that are not only functional but also attractive to the eyes.

冲压

Lewei Precision involves stamping of sheet metal in order to shape it into cold-formed parts. This is a high precision process that guarantees a high consistency in quality in the case of large production volume which makes it ideal in the production of parts which have detailed and tight tolerances.

乐为精密钣金加工的工作原理

At Lewei Precision, our network of sheet metal stores in China is tremendous and that makes us deal with a very diverse set of projects. We also begin by translating your CAD drawings into machine code, whether as complex prototypes or full assemblies. The metal is then cut, bended, welded, riveted and vamped into shape by our experienced team to fit your specific requirements.

We also provide our clients with multiple finishing options which means that our parts will not only work to their full capacity, but also have a polished and professional look. We provide single unit and large scale production with high quality work at the required time and even the tightest tolerance of less than 0.01mm and a short lead time of 1 day.

Lewei Precision Surface Finishing Options for Sheet Metal

We can provide a large assortment of sheet metal fabrication surface finishing to improve the functionality and look of your custom metal components. Having better corrosion protection or smooth polished finish, or a particular finish, we can offer you a variety of finishing options.

粉末涂层

Powder coating forms a thick and hard coating to the surface which provides good wearability. It is also available in a very broad color and texture palette and therefore can be applied to many types of surfaces and usages.

阳极氧化

Anaodizing is a finishes process that enhances wear and corrosion resistance properties particularly on aluminium parts. It can also be dyed in color thus is also good in terms of durability and beauty.

拉丝处理

A brushed finish offers a satin-like texture in one direction only, making the marks and scratches on the metal less visible. It is mostly applied to stainless steel components, and it will provide a contemporary and professional appearance.

电镀

Electroplating is a process of attaching a coating of the metal surface to the parts to enhance the wear life, resistance to corrosion, and surface conductivity. This finish is best suited to those parts which are needed as more durable and of a sleek look.

抛光

Polishing gives a high-gloss finish to metal parts and lowers the roughness of the surface as well as improving the aesthetic value of the parts. It is ideal when the appearance of the part is a key consideration.

Black oxidizing

Black oxidizing is a conversion coating that is normally used on ferrous metals. It enhances resistance to corrosion and reduces the amount of light reflected meaning it is ideal in those parts that are exposed to severe environments.
