Precision Sheet Metal Fabrication Capabilities
With over 100 advanced machines, like laser cutters, bending machines, and welders, in our China-based network, we can supply any quantity of sheet metal parts, from low-volume prototypes to high-volume production. Our domestic fabricators and engineers provide precision and fast delivery.
- レーザー切断
Laser cutting uses a focused laser beam to cut, etch, or engrave materials, vaporizing or melting them for precise edges and complex patterns based on designer specifications.
- Bending
Bending applies a force to a thin sheet of metal to shape it into various geometries, like U-shape, V-shape, or channel shape.
- Welding
Welding is the process of joining two or more metal pieces using heat, pressure, or both to form a strong bond. It combines skill and precision to create durable, sturdy metal structures.
- Punching
Punching uses a punch tool to create holes or shapes by forcing it through a die, cutting the metal with a shearing action for precise, clean results in fabrication.
- Riveting
Riveting is a semi-permanent joining method using mechanical fasteners (rivets) to connect sheet metal parts. It’s faster and much cost-effective than welding.
- Stamping
Stamping uses dies and presses to shape flat metal sheets into different forms, creating complex, three-dimensional designs through cold-forming techniques.

板金加工の利点
Sheet metal fabrication offers a highly efficient and scalable manufacturing solution, from sheet metal prototyping to high-volume production. By combining processes such as laser cutting, bending, stamping, and welding, precision sheet metal fabrication delivers consistent part quality and tight tolerances — even for complex geometries.
One of the key advantages of sheet metal fabrication services is cost efficiency, especially for low-to-mid and large production runs. Fast turnaround times, repeatable processes, and minimal tooling requirements help reduce overall manufacturing cost while maintaining production-grade quality.
Custom sheet metal fabrication also provides excellent design flexibility. Parts can be produced using a wide range of metals, thicknesses, and surface finishes such as powder coating, anodizing, or plating. This makes sheet metal fabrication an ideal choice for industrial, electronics, automotive, and heavy equipment applications where durability, precision, and scalability are critical.
よくある質問
How do I get started with a custom sheet metal fabrication project?
Getting started with custom sheet metal fabrication at PartsMastery is simple. Upload your CAD files (STEP, IGES, DXF, or DWG) to our online sheet metal fabrication quote system. You can select materials, thickness, tolerances, and surface finishes in just a few steps.
If your design needs optimization, our engineers provide DFM feedback for sheet metal parts to improve manufacturability, cost, and lead time before production begins.
Once the quote is approved, we move directly into fabrication and quality inspection.
How long does it take to receive my custom sheet metal parts?
The lead time for receiving your custom sheet metal parts depends on several factors including the complexity of the parts, the quantity ordered, and the specific fabrication processes required. For simple parts, we can often deliver within as little as 3 days from the time your order is placed and the design is confirmed.
For more complex assemblies or larger volumes, the production time will be extended accordingly. Once you submit your design through our online quoting system, we provide an estimated delivery timeline along with your quote. This estimate takes into account the current workload in our fabrication facilities and the specific requirements of your project.
We strive to minimize turnaround time without compromising on quality, ensuring you receive your parts as quickly as possible while maintaining the highest standards of fabrication.
How much does sheet metal fabrication cost?
The cost of sheet metal fabrication services varies widely based on several factors including the complexity of the parts, the type of material used, the quantity of parts, and the specific fabrication processes required. For straightforward, simple parts, the cost can be quite competitive, especially when leveraging our efficient production techniques and advanced machinery.
To get a specific cost estimate, we encourage you to use our easy-to-use online quoting system. Here, you can upload your design files, select materials, specify quantities, and choose finishing options. Our system will provide you with a detailed quote reflecting the precise cost of your project.
For larger or more complex orders, costs will adjust based on additional processing and labor required. Our goal is always to offer the best value, combining cost-effectiveness with high-quality results.
Can you handle both sheet metal prototyping and production?
Yes. We support sheet metal prototyping, low-volume production, and scalable manufacturing. This allows you to validate designs quickly and transition seamlessly into production without changing suppliers.
Our custom sheet metal fabrication service is designed for engineers and procurement teams who need speed, consistency, and long-term reliability.
Is there a minimum order quantity for sheet metal fabrication services?
At PartsMastery, we support projects of all sizes. We accommodate both small and large production runs, offering our services for everything from a single prototype to mass production. Importantly, we do not enforce a strict minimum order quantity. This flexibility allows customers, whether startups or large corporations, to leverage our sheet metal fabrication services tailored to their specific needs and scales.
What materials are commonly used in sheet metal fabrication?
Common materials for custom sheet metal fabrication include aluminum, stainless steel, carbon steel, galvanized steel, and copper. Material selection depends on strength, corrosion resistance, weight, and application requirements.
Our engineers can help you choose the right material for performance, cost, and manufacturability.
What’s K factor in sheet metal?
The K factor in sheet metal fabrication is a crucial value that influences the accuracy of bend allowances when calculating the flat length of a sheet before bending. Essentially, the K factor represents the ratio of the neutral axis’ location to the material thickness. During bending, the inner surface of the metal compresses while the outer surface stretches, but the neutral axis remains unstressed.
Determining the correct K factor is vital because it directly affects how much the sheet metal will stretch during bending. Typically, the K factor value ranges between 0.3 and 0.5, depending on the material and the type of bending being performed. Accurately calculating this factor ensures that the bent sheet metal parts fit precisely as designed, maintaining dimensional integrity and functionality.
What is the difference between sheet metal and plate metal?
The primary difference between sheet metal and plate metal lies in their thickness and applications. Sheet metal is typically defined as metal formed into thin and flat pieces that range in thickness from about 0.006 inches to 0.25 inches. Due to its malleability, sheet metal is commonly used in applications requiring precise bending and shaping such as automotive bodies, aircraft panels, and household appliances.
On the other hand, plate metal is thicker, generally starting from 0.25 inches and going up to several inches. Plate metal is used in applications where durability and robustness are more critical, such as in constructing buildings, bridges, and heavy machinery. The thicker nature of plate metal makes it ideal for structural applications where high strength and resistance to deformation are necessary.
