Custom Parts

TonZa offers fast and cost-effective sheet metal fabrication services, including a free DFM report and expert engineering advice. We specialize in sheet metal cutting, bending, welding, and assembly for a wide range of projects.

Laser Cutting

It is a machining process performed on a lathe to create narrow cuts or recesses on a cylindrical workpiece.

Plasma Cutting

This operation is commonly performed to create external or internal threads with precise dimensions and pitch.

Bending

also known as cut-off, is a machining process used on a lathe to separate a finished part .

Stamping

It is typically performed using a single-point cutting tool that removes material from the inner surface of a hole.

Punching

It is a machining process used on a lathe to create a textured pattern or raised ridges on the surface of a workpiece.

Welding

It is a machining process used on a lathe to create a conical shape (taper) on a metal or plastic workpiece.

Why Choose ours Sheet Meatal Fabrication Services?

Capabilities of Sheet Meatal Fabrication Services

Our sheet metal fabrication service meets industry-standard precision tolerances, ensuring consistent accuracy and a flawless component fit.

Design Guidelines

Optimize your designs for manufacturability with our expert guidelines and feedback, ensuring the best results in Sheet Meatal Fabrication.

Bend Design

1. Minimum bend radius: Should be ≥ 1× the sheet thickness to avoid cracking

2. Avoid sharp bends: Use internal radii to reduce material stress..

3. Bend relief: Provide relief cuts to prevent tearing in tight bends.

Hole Placement and Size

1. Minimum hole diameter: ≥ sheet thickness to prevent distortion..

2. Hole edge distance: Maintain a gap of ≥ 2× sheet thickness from edges or bends..

3. Standard hole sizes: Use standard drill bit sizes to minimize custom tooling costs.

Cutout and Slot Design

1. Minimum slot width: ≥ sheet thickness to avoid bending issues..

2. Corner radii for cutouts: Use R ≥ 0.5 mm to reduce stress concentration..

3. Tab and notch clearance: Maintain a minimum gap of ≥ 1 mm for clean cutting.

Tolerances

1. General cutting tolerance: ±0.2 mm.

2. Bending tolerance: ±0.5 mm (depends on material and thickness).

3. Hole placement tolerance: ±0.1 mm for laser cutting.

Flange and Hemming Guidelines

1. Minimum flange width: 4× sheet thickness for rigidity..

2. Hemming: Used to reinforce edges, reduce sharpness, and improve strength..

3. Hemming gap: Maintain a 0.5 mm clearance for tightly closed hems..

Welding and Joining Considerations

1. Minimize welds: Welding increases cost and may cause heat distortion.

2. Spot welding vs. full welding: Spot welding is faster and preferred for thin sheets.

2. Leave access for welding tools: Ensure joints are easily reachable..

Surface Finishing

1. Powder coating: Durable, protective layer.

2. Anodizing: Corrosion resistance for aluminum..

3. Plating & painting: Additional aesthetic and protective options..

Nesting and Material Utilization

1. Optimize part layout for minimal material waste.

2. Use standard sheet sizes to reduce cutting complexity and cost.

3. Reduce small, intricate features that may be difficult to fabricate..

Surface Finishes

We are offering over 20 options of surface finishes to fulfill both your functional and aesthetic requirements.

Brushing

is a surface treatment that grinds the workpiece, creating decorative lines for an attractive finish.

Sand Blast

uses high-speed sand flow to clean and roughen a product's surface.

Polishing

uses abrasives or buffing wheels to smooth surfaces, remove imperfections, and create a reflective finish.

Tumbling

is a surface treatment that rotates materials with abrasive media in a drum or container.

Anodizing

enhances by forming a protective layer that improves corrosion resistance, hardness, and appearance.

Painting

This process improves the tactile feel but may be prone to scratches.

Black Oxide

an oxide film used to improve corrosion resistance, enhance appearance, and reduce light reflection.

Electroplating

is used for functional, decorative, and corrosion-resistant purposes in various industries.

Powder Coating

applies electrostatically, then cures it with heat or UV light for a durable, attractive finish.

Alodine

is a protective conversion coating for aluminum that prevents corrosion and acts as a primer for painting.

Passivation

enhances corrosion resistance by immersing it in an acid to remove contaminants and form a protective layer.

Electroless Plating

is a chemical process that deposits metal onto a substrate without electrical current.
