OUR SERVICES

Sheet Metal Fabrication

Sheet metal fabrication supports flat and formed metal parts for prototypes, functional assemblies, enclosures, brackets, panels, and low-volume production runs. LEAD MFG helps engineering and sourcing teams choose cutting and forming methods, review manufacturability, coordinate production, and prepare parts for testing, assembly, or end-use applications.

Capabilities

Our Capabilities

Laser cutting is used for accurate flat profiles, covers, brackets, panels, gaskets, and formed sheet metal blanks. Suitable for prototypes and production runs where edge quality and feature accuracy matter.

We use stamping and forming to produce sheet metal parts with controlled bends, flanges, tabs, ribs, and structural features. Supports progressive die operations and single-hit forming depending on quantity and complexity.

Photochemical etching can make thin metal parts with complex patterns, fine features, and tight tolerances that mechanical cutting cannot achieve. Ideal for shims, screens, EMI shields, and decorative panels.

Water jet cutting is good for thick plates, heat-sensitive materials, and parts that require no heat-affected zone. Supports aluminum, steel, brass, copper, and composite sheet materials.

Join sheet metal components with TIG, MIG, spot welding, or riveting depending on material, strength requirements, and cosmetic needs. Fabricated assemblies with controlled tolerance stack-up, no multi-vendor hand-off.

Sheet Metal Fabrication Workshop

LEAD applies a variety of possible metal forming technologies and equipment to improve the speed and ability to cope with mass production applications.

Surface Finishing Options

Surface finish is applied to parts after they have been machined to create a unique surface layer to meet the hardness, chemical resistance, and appearance requirements of the products. It depends on material properties and the application of the part. LEAD offers the following finishing options for sheet metal services:

Anodizing

Powder Coating

Bead Blasting

Brushing

Shenzhen, Dongguan and Bac Ninh roles are visible and easy to verify.

Frequently Asked Questions

What type of design files can you accept?

We accept 3D CAD files in STL, STP, STEP, OBJ IGS, or IGES format and 2D drawings(jpg, png, gif, BMP, pdf) with dimensional details and specific manufacturing requirements.

How long does it take to get a pricing quote?

We respond within 2 hours after your request. Princing quote will be send within 8 hours.

Can I use my master model to make duplicate copies for vacuum casting or CNC machining?

Yes, master models are used to create silicone molds for vacuum casting and can be made from any rigid solid that can withstand heat up to 100 °C. Models used for CNC machining will be 3D scanned to create a CAD/CAM program for production.

How quickly can I get my parts?

Quality parts less than 1000pcs can be made in as fast as one week if you provide complete 2D and 3D CAD models. More complex parts requiring other special features will take longer. As for shipping, most of our shipments are via air freight, which can take 5-7 days from China to Europe or North America.

How do we protect your data and intellectual property？

We respect your intellectual property. None of your information, images, files or likenesses will be shared with any third party, and it will not be used for any advertising, marketing, or promotional use without your explicit written authorization. If you would like to sign NDA agreement, please contact our team for support.

How about the quality guarantee policy?

We follow the ISO/IATF standard and guarantee that we will rework the products or refund them if there are any quality problems. The full-dimensional report, material certification, or first article inspection are provided on request before order placement.
