Your Trusted Partner for Precision Sheet Metal Fabrication

Sheet metal Fabrication is the cornerstone of modern manufacturing, forming the key components of numerous industries. From sturdy shells to complex parts in aerospace systems, sheet metal parts are everywhere. The sheet metal process transforms flat metal sheets into important components and structures through cutting, bending, and assembly. As a fundamental manufacturing technology, it is widely applied and is crucial for technological progress and daily life.

ShengPeng has been at the forefront of this field for 18 years, providing precise and reliable solutions to global customers.

The Ubiquitous Application of Sheet Metal Fabrication

The versatility of metal sheets makes them indispensable in numerous fields. Their strength, durability, and adaptability enable engineers to design complex, lightweight, and cost-effective solutions. In the telecommunications industry, metal sheets are used to manufacture sturdy equipment racks and shielding cabinets to protect precision electronic equipment. In the automotive sector, they are employed in various components such as chassis components, brackets, exhaust systems, and body panels, emphasizing both strength and weight reduction.

The aerospace and defense industries have extremely high requirements for product quality. They use special alloys to manufacture lightweight yet extremely strong components for aircraft interiors, the shells of aviation electronic equipment, and supporting structures. In the field of consumer electronics, metal sheets form the fashionable and durable shells of laptops, servers, and household appliances. Moreover, the construction industry also uses metal products as materials for architectural decoration, HVAC pipes, and structural supports. This wide range of applications highlights the need for manufacturers who can understand the unique requirements of each industry.

• Transition: As we have seen, sheet metal is fundamental to countless applications. At Shenpeng, we transform raw metal into these critical components using a meticulous and advanced manufacturing process, ensuring every part meets exact specifications.

Our team, composed of experienced engineers and technicians, will closely collaborate with customers to optimize the design, achieve cost-effectiveness and performance improvement, while not sacrificing quality. Working with Shen Peng means that you can leverage his 18 years of accumulated rich knowledge to help your products succeed.

Our Comprehensive Sheet Metal Fabrication Process

Our fabrication process is a streamlined, multi-stage operation designed for efficiency, precision, and quality at every step. We combine advanced technology with expert craftsmanship to ensure your parts are produced to the highest standards. From the initial design review to the final packaging, every phase is meticulously controlled and documented.

Step 1: Design and Engineering Consultation

The journey begins during your design phase. Our engineering team will conduct a thorough "Design for Manufacturability" (DFM) analysis. We will review your CAD files (such as STEP, IGES, DXF, etc.) to identify potential production issues, propose cost reduction suggestions, and recommend the most efficient manufacturing methods. This collaborative step is crucial for avoiding costly errors and ensuring a smooth production process.

Step 2: Precision Cutting and Blanking

Once the design is finalized, the flat metal sheet will be cut into the required size. Shenpeng Company uses advanced laser cutting machines for high-speed and ultra-precise cutting. This technology can achieve complex geometries and strict tolerance requirements, resulting in finished products with smooth edges and almost no burrs. For large-scale projects, we also use CNC stamping technology to efficiently manufacture standard shapes and holes.

Step 3: Forming and Bending Operations

These flat-cutting pieces are processed into the final three-dimensional shapes. Our workshop is equipped with multiple modern CNC bending machines. It is capable of completing complex bending processes in large-scale production batches with highly precise angles and accurate dimensions. The professional skills of the operators ensure that even complex bending sequences can be executed perfectly.

Step 4: Joining and Welding Techniques

Assembly usually involves connecting multiple components together. Shenpeng Company offers a variety of welding techniques, all of which are operated by certified welders. TIG welding is favored for its clean, high-strength welds formed on materials such as aluminum and stainless steel, which ensures the integrity of the structure and achieves excellent surface results.

Step 5: Surface Finishing and Deburring

The surface treatment effect of the components is of vital importance for both appearance and functionality. We offer a variety of surface treatment services. These services include grinding treatment to remove sharp edges, sandblasting treatment to create textures, and powder coating treatment that is durable, corrosion-resistant and has bright colors. Additionally, there are other options such as anodizing (suitable for aluminum) and electroplating available for selection.

Step 6: Rigorous Quality Control and Inspection

Quality is not something considered after the fact; it is integrated throughout every stage. Before shipment, each batch of components undergoes final inspection. We use coordinate measuring machines (CMM), calipers, and gauges to verify that all dimensions, tolerances, and appearance requirements comply with the standards specified in your technical drawings.

Step 7: Final Assembly and Packaging

We can offer some additional value-added services, such as simple or complex mechanical assembly, installation of threads, or integration of purchased components. Finally, we will carefully package each part according to their specific requirements to prevent damage during transportation and ensure that they arrive in perfect condition.

• Transition: A precise process is vital, but it is only as good as the materials it shapes. Shenpeng offers a wide selection of high-quality metals, allowing you to choose the perfect material for your application's mechanical, environmental, and budgetary needs.

Material Selection: Choosing the Right Metal for Your Project

Selecting the appropriate material is a critical decision that impacts a part's function, cost, and longevity. Shenpeng provides expert guidance and offers a comprehensive inventory of materials to meet diverse application requirements. We work with all common grades and can source specialized alloys upon request.

Carbon Steel and Mild Steel

Ideal for high-strength structural components and brackets where cost-effectiveness is a priority. It is easy to weld and form but requires surface finishing to prevent corrosion.

Stainless Steel (304 & 316)

It is highly suitable for applications that require corrosion resistance, hygiene and aesthetic properties. The 304 steel type is commonly used for general purposes, while the 316 steel has a stronger ability to resist chemical substances and salt water erosion, making it particularly suitable for use in marine and medical environments.

Aluminum (5052 & 6061)

A popular choice for its excellent strength-to-weight ratio, natural corrosion resistance, and good conductivity. Aluminum is easier to form than steel and is widely used in aerospace, electronics, and automotive industries.

Other Specialized Alloys

We also work with copper, brass, and galvanized steel for specific electrical, decorative, or outdoor applications. Our team can advise on the best material for your project's unique challenges.
