Sheet Metal Prototypes

Sheet metal fabrication is one of XinPrototype’s services, offering a fast and cost-effective solution for your projects. Via bending, punching, and cutting standard gauge metal for both prototypes and low-volume production runs. Sheet metal fabrication produces durable, end-use metal parts with a wide selection of materials and finishes that meet your specifications, for a variety of industries like: Automotive, Medical device, Aerospace, electronics, energy, and robotics.

Processing

Auto Bending

CNC bending machines are capable of forming sheet metal from 0.5 to 5 mm with perfect precision, and can repeatable bends within ±0.2°.

Laser Cutting

High‑power fiber laser delivers precision cuts up to 20 mm thick steel, ensuring smooth surface, no burrs, and consistent quality on every part.

Welding

TIG and MIG welding sheet‑metal parts with expert precision and minimal distortion, to achieve of producing complex structural parts.

What is Sheet Metal Parts?

Sheet metal is a set of manufacturing processes used to turn sheet metal stock into functional parts. The sheet metal is usually between 0.006 and 0.25 inches (0.015 and 0.635 centimeters) thick.

There are several processes that fall under the umbrella of ‘sheet metal fabrication’. These include cutting, bending and punching, and can be used either in tandem or individually.

Customzied sheet metal parts can be used to create either functional prototypes or end-use parts. For end-use sheet metal parts usually with a surface finish, such as anodized, powder coated, painting etc.

Common Questions About Sheet Metal Parts

Q1: What is the typical thickness range for a sheet plate?
A1: Most sheet metal part uses thicknesses between 0.5 mm and 5 mm, depending on the design and strength requirements.

Q2: Which processes are commonly used for sheet metal?
A2: Typical has laser cutting, bending, stamping, and welding. These allow sheet metal to be shaped into precise parts for industrial and consumer use.

Q3: Sheet metal is good for mass production?
A3: Yes. Sheet metal fabrication is flexible enough to handle both prototypes and high-volume production. From 1pc to 10000 pieces.

Q4: What is the typical lead time for sheet metal parts?
A4: Small orders take 5–8 days, and high-volume production may take 2–4 weeks.

Q5: How to estimate sheet metal part cost?
A5: Costs depend on material type, part complexity, quantity, and finishing requirements etc factors.

Q6: How does CNC machining combine with sheet metal?
A6: CNC machining can mill the sheet metal part to make it more precise. So that improving accuracy and surface quality.
