Our Sheet Metal Fabrication Capabilities
DSR has extensive machining capabilities and can develop cost-effective solutions based on your drawings and requirements. With our state-of-the-art machine tools and skilled operators, we can manufacture high-precision sheet metal parts for you. From small batch manufacturing to large-scale production, we can handle it all.
Laser cutting is suitable for a wide range of precision custom sheet metal parts. It uses a high-power focused laser beam for precise cutting on metal sheets. We produce parts with exact dimensions and complex patterns based on your drawings and specifications.
Forming and bending is a process that transforms flat sheet materials into three-dimensional structural components. We can bend thin metal sheets into sheet metal parts of various geometric shapes, with stable structure and high assembly accuracy.
Welding is used to combine cut and bent sheet metal parts into more complete and robust structural components. Through this process, we help our customers obtain sheet metal components that are ready for assembly, painting, or end-use applications.
Punching is a process that uses punch tools under pressure to cut metal sheets, thereby forming holes or specific shapes. This process is very suitable for mass production because it can significantly improve processing efficiency and reduce unit costs.
Metal stamping is ideal for the mass production of sheet metal parts with consistent dimensions and high structural repeatability. We offer custom stamping services tailored to our customers’ product designs and quantity requirements.
We also offer custom sheet metal enclosure fabrication services. These enclosures can be used to protect a wide range of equipment and industrial components. They also feature tight tolerances, smooth surfaces, and reliable performance.

Sheet metal fabrication is the process of transforming flat metal sheets into custom parts and components through cutting, bending, welding, and surface finishing. Our sheet metal fabrication services produce high-precision, durable, and functional parts widely used in industrial equipment, automotive components, and commercial appliances.
CNC machining typically removes material from a solid metal block to create parts, while sheet metal fabrication shapes parts by cutting, bending, and forming flat metal sheets. Sheet metal fabrication is ideal for parts requiring lightweight, high-strength, complex geometries—especially large flat plates, enclosures, or structural housings.
Simply put, sheet metal fabrication cuts, bends, and stamps sheet metal into your desired shape, while welding securely joins these fabricated parts together. In other words, sheet metal fabrication creates the parts, and welding assembles them.
Within our services, we typically include welding as part of sheet metal fabrication. Depending on project requirements, we offer MIG welding, TIG welding, and spot welding to ensure part precision and strength.
We process a wide range of materials, including stainless steel, aluminum, carbon steel, and coated metals. Thicknesses typically range from 0.5mm to 20mm, with strict tolerance control of ±0.01mm per batch to guarantee dimensional consistency and high quality.
