Sheet Metal Fabrication

Supported by systematic precision manufacturing capabilities and extensive technical experience, EACHANCE provides one-stop manufacturing solutions covering engineering collaboration, design optimization, precision sheet metal fabrication, complete product assembly, and reliable delivery.

Precision Cutting

Precision cutting is the first stage of sheet metal fabrication. Metal sheets are cut or punched to the required shapes and dimensions according to product drawings and developed flat patterns, preparing the components for subsequent bending, welding, and assembly.

1. CNC Turret Punching

CNC programs control punching, slotting, flanging, louvre forming, and other sheet metal operations. The process delivers high production efficiency and consistent hole positioning, making it well suited to repeat and volume production.

2. Fiber Laser Sheet Cutting

Fiber laser technology provides high-precision cutting of metal sheets across a range of material types and thicknesses. It produces complex profiles with high dimensional accuracy and clean edge quality, supporting fast and efficient material preparation.

3. Fiber Laser Tube Cutting

Fiber laser tube cutting is used to cut, drill, mitre, notch, and prepare joints in round, square, rectangular, and specially shaped tubes. Accurate tube processing improves structural fit and helps reduce errors during subsequent welding and assembly.

CNC Forming

CNC forming uses bending, pressing, drawing, and roll-forming processes to transform flat sheet metal into specified angles, curves, and three-dimensional structures that meet the dimensional and geometric requirements of the product drawing.

1. CNC Panel Folding

CNC panel folding is suitable for edge folding, flanging, and closing operations on long sheet metal components. It is commonly used for enclosures, doors, panels, and building-envelope components. The process produces straighter long edges, cleaner appearance, and improved structural rigidity.

2. CNC Press Brake Bending

CNC press brake bending forms sheet metal into specified angles and profiles and is one of the core processes in sheet metal manufacturing. Stable dimensions and consistent bending angles help ensure accurate fit and alignment during product assembly.

3. Roll Forming

In roll forming, sheet metal passes progressively through a series of forming rollers to produce long components with a consistent cross-section. The process offers high forming efficiency and excellent profile consistency, making it suitable for stable, repeat production.

Assembly and Finishing

Through positioning, fastening, riveting, welding, hardware installation, and surface finishing, individual sheet metal parts are transformed into complete components or finished products.

1. Welding

Sheet metal parts are permanently joined using suitable welding processes, including MIG/MAG welding, TIG welding, and laser welding.

The appropriate process is selected according to the material, thickness, structural strength, appearance, and distortion-control requirements, helping ensure reliable joints and consistent product quality.

2. Riveting

Riveting mechanically joins sheet metal parts using rivets or other fastening elements. It is particularly suitable for thin sheets, dissimilar materials, and components where heat from welding may cause distortion or surface damage.

The process offers reliable connection, low thermal impact, and good consistency in batch assembly.

3. Electrostatic Powder Coating

Electrostatic powder coating applies charged powder particles evenly to the surface of a metal workpiece. The coated component is then heated in a curing oven, allowing the powder to melt, flow, and form a continuous protective finish.

The process improves surface appearance, coating consistency, and durability while supporting a range of colors, gloss levels, and textures.

1. Can you manufacture our product?

We can assess your product based on drawings, samples, or technical requirements. Our review covers the material, sheet thickness, dimensions, tolerances, structure, welding, surface finishing, assembly requirements, and order quantity to determine whether our equipment and manufacturing processes are suitable.

2. What materials and sheet thicknesses can you process?

We process carbon steel, stainless steel, aluminium, copper, and titanium-zinc sheet.

Our maximum sheet thicknesses are:

Carbon steel: up to 18 mm
Stainless steel: up to 8 mm
Copper: 3–5 mm
Aluminium: up to 5 mm
Titanium-zinc sheet: subject to drawing review

Special materials or thicknesses will be evaluated according to the product drawings and technical requirements.

3. What products are suitable for your large powder-coating oven?

Our large batch-coating and curing system is suitable for large frames, cabinets, complex structures, and high-mix, low-volume orders.

Key specifications include:

Effective oven dimensions: 9,000 × 2,750 × 3,500 mm
Maximum workpiece weight: 300 kg
Operating temperature range: 50–200°C

Final suitability depends on the workpiece dimensions, structure, hanging method, thermal capacity, powder specification, and curing requirements.

4. Can you provide sheet metal fabrication, powder coating, and assembly under one roof?

Yes. Our capabilities include precision cutting, CNC punching, bending, welding, powder coating, riveting and fastening, hardware and purchased-component installation, component assembly, inspection, and packaging.

The final scope of work will be determined by the project drawings and bill of materials.

5. How do you ensure consistency between samples and production batches?

Before volume production, we can carry out first-article verification. During production, inspections are performed according to the approved material, drawing revision, critical dimensions, welding, assembly, and appearance requirements.

Finished products undergo final inspection and pre-shipment verification before delivery.

6. What is your minimum order quantity? Can you produce samples first?

Minimum order quantities depend on the material, manufacturing processes, surface finishing, tooling or fixtures, and purchased-component requirements.

We can evaluate prototypes, trial production, small batches, and volume-production projects. Sample quantities and costs will be confirmed after reviewing the drawings.

7. How long does quotation and production normally take?

Our typical lead times are:

Quotation response: within 24 hours
Sample production: approximately 5 days
Volume production: approximately 12 days

Actual lead times depend on drawing completeness, material availability, manufacturing complexity, surface-finishing requirements, purchased components, order quantity, and current production capacity.

8. What information should I provide when requesting a quotation?

Please provide as much of the following information as possible:

2D or 3D drawings
Material and sheet thickness
Order quantity
Dimensional tolerances
Surface-finishing requirements
Assembly requirements
Quality and inspection standards
Required delivery date

For assembly projects, please also provide a bill of materials and specifications for purchased components. If the documents contain confidential business information, a non-disclosure agreement may be signed before
