What is precision sheet metal processing
Imagine receiving an order for a metal part for a new product, opening the package only to find that the part is misaligned and cannot be assembled properly, which will undoubtedly cause delays to the entire production line. For manufacturers, such problems caused by poor quality metal parts are extremely troublesome.
Whether it is aerospace, automotive assembly, or electronic equipment, high-quality, precision sheet metal processing metal parts are indispensable, providing a reliable solution to ensure that every project can achieve perfect results.
1.Precision sheet metal processing process
(I) Material selection
Material selection is the beginning of the precision sheet metal processing process. Metals such as aluminum, steel, and copper are often used in precision sheet metal manufacturing due to their unique strength, ductility, and corrosion resistance.
The selection of materials depends largely on the specific application scenario. For example, aluminum is lightweight and highly rust-resistant, making it a preferred material for aerospace components; while the high strength of steel makes it widely used in automotive manufacturing.
(II) Design
The design stage is a key link in precision sheet metal processing. Engineers use computer-aided design (CAD) software to create detailed blueprints of parts. CAD software can perform precise measurements and simulations to ensure the feasibility of the design under actual conditions.
Design for manufacturability (DFM) is the core point of this stage, which requires the design to be both practical, easy to produce, and cost-effective. Engineers need to comprehensively consider factors such as material thickness, bending radius, and hole location to avoid complex problems during the manufacturing process and provide guarantees for the smooth progress of precision sheet metal processing.
(III) Cutting
Laser cutting: Cutting metal with a focused laser beam has extremely high precision, is particularly suitable for complex designs, can effectively reduce material waste, and performs well in cutting parts with high precision requirements in precision sheet metal processing.
Plasma cutting: Cutting metal with a high-speed plasma (ionized gas) jet, which is faster than laser cutting and is often used to cut thicker materials, providing an effective means for processing metal sheets of different thicknesses.
Water jet cutting: Cutting metal with a high-pressure water jet injected with abrasive particles. This technology has a wide range of uses and can cut a variety of materials without generating heat. It is particularly suitable for cutting high-temperature sensitive materials.
(IV) Forming and shaping
The cut metal needs to be shaped into the desired shape through various processes, such as bending, stamping and rolling. Bending is to fold the metal into a specific angle using a bending machine; rolling is to place the metal plate on multiple rollers to obtain the desired thickness; stamping is to use a mold to press the shape into the metal. These processes work together in precision sheet metal processing to gradually shape metal parts.
(V) Connection and assembly
After the metal parts are cut and formed, they need to be connected and assembled into the final product through appropriate methods. Common connection methods include welding, riveting and bonding.
Welding: Using heat to melt and fuse metal parts, precision welding can ensure that the joint is strong and durable without compromising the integrity of the metal.
Riveting: Using rivets (metal pins) to insert into pre-drilled holes and flatten them to fix two pieces of metal together, often used in situations where welding is not suitable to ensure the reliability of the connection.
Adhesive bonding: When the metal is too thin to weld or a smooth surface is required, strong adhesives are often used to bond metal sheets to meet special connection requirements and ensure the quality of precision sheet metal processing products.
(VI) Finishing
The final link of precision sheet metal processing is the finishing process, including painting, powder coating, anodizing, etc., which are used to improve the appearance and performance of the metal surface.
2.Advantages of precision sheet metal processing
