The metal sheet metal forming process is widely used by the top sheet metal fabrication china company. The metal working technology that plastically deforms a thin metal sheet by an external step force, exceeding the material’s yield strength, bending and drawing into various complicated shapes without reducing the material itself. Metal sheet metal forming processes generally require the use of high quality molds to obtain the desired metal product, and Mulan MFG offers the high quality molds among the competitors in the sheet metal fabrication china industry.

Competent sheet metal fabrication ability

Use pressure to create the required shape of the metal sheet in the mold, and closely fit the metal mold cavity. It has the characteristics of high efficiency and low cost. The stamping forming technology includes: punching, stamping and cutting, bending forming, embossing, Embossing, flanging, etc.

By applying pressure to the metal plate, the ductility of the material is released, and various shapes and angles are created. It is a very efficient and economical sheet metal fabrication services. Relying on CNC programs to achieve higher precision.

Applying an increased amount of compression to the sheet metal, changing the shape of the material at the limit of ductility, is a cold-working molding process, which has a high degree of versatility, can manufacture complex and delicate parts, and has extremely high precision and batch manufacturing capabilities.

Relying on the laser beam to focus on the cutting line of the plate, the material is instantly heated and melted or vaporized, thereby cutting and separating the material. Mulan MFG has 3000KW-10000kw laser cutting  equipment that can cut 30mm thick stainless steel plates or thinner metal plates.

Metal Welding Services

The separated metal materials are melted by a high-temperature welding gun and then re-spliced to assemble them into the desired product shape. Protective gas is used during the welding process to ensure that the process is not polluted and oxidized, so that the welding is firmer and cleaner.

Quality Control Of sheet metal fabrication

Mulan MFG is the industry-leading cnc milling china. Strict quality control is our principle of doing business to ensure that high-quality CNC milling parts are delivered to customers on time. We will always carefully complete any product design and complex details mentioned by customers. And has the ability to efficiently handle large-scale order requirements and small-scale prototype projects.

01. Raw material quality inspection

We never cut corners, all materials will have a material inspection report (chemical report & physical report) before they are put into storage.

02. Initial size inspection

Before the CNC milling services,Measure the size of the material to prevent insufficient machining allowance and poor material.

03. Production process control

Develop a production schedule flow chart, control time nodes and production plans, and prevent delayed delivery.

04. Mid-term dimensional inspection

Pay attention to each cnc milling processing node, review possible quality risks during product processing, and stop the processing of problem products in time

05. Final size inspection

Relying on advanced CMM and other inspection equipment to carry out size inspection on cnc milling parts.

06. Surface & installation testing

100% shape quality control, and install and test product functions, reject and isolate parts with quality problems such as scratches and unqualified surface treatments.

What is custom Sheet Metal Fabrication ?

Sheet metal fabrication services is a very flexible metal working process, which is widely used in most industries to manufacture parts or steel structure components.Usually sheet metal fabrication can solve a variety of product types such as metal shells, metal containers, and metal supports.

Compared with metal casting and cnc machining, it has the advantages of higher efficiency, more economical cost-effectiveness, more durable products, more flexible assembly and testing, etc. In fact, when designing products, product designers generally prefer the sheet metal working process, unless product requirements do not allow it.
