Our sheet metal processing capabilities
We possess comprehensive sheet metal processing capabilities, utilizing mature processes and precision equipment to provide customers with high-precision, high-reliability component manufacturing. Our processing capabilities cover everything from metal sheet cutting and bending to subsequent related machining, adapting to various structural and dimensional requirements.
Laser cutting is one of the most common and core processing technologies in modern sheet metal manufacturing. We utilize advanced CNC laser cutting equipment to perform high-speed, high-precision cutting of various metal sheets. This process is suitable for manufacturing complex geometries, intricate holes, and narrow slit structures.
Laser cutting capabilities include:
- Material types: Common sheet metal materials such as stainless steel, aluminum, copper, and low carbon steel.
- Thickness range: From thin plates to medium-thick plates, the specific range is adjusted according to the material type.
- Machining accuracy: Smooth cutting edges, stable dimensional accuracy, suitable for subsequent bending and assembly.
- Applicable scenarios: Structural components, housings, chassis panels, connecting plates, decorative parts, etc.
Laser cutting technology can not only achieve high-precision edge quality, but also provide a good benchmark for subsequent bending, welding and other processes.
Bending is a crucial process for shaping flat metal into three-dimensional structures, widely used in sheet metal manufacturing for structural components such as chassis, frames, and brackets. We utilize high-precision CNC bending equipment to achieve controlled forming of different materials and thicknesses, ensuring consistent angles and structural stability.
Our bending processing capabilities include:
- Material adaptability: Supports multi-angle bending of materials such as stainless steel, aluminum, and low-carbon steel.
- Minimum bending radius control: Avoid material cracking or excessive deformation through process optimization.
- Complex forming support: Can process complex structures such as multi-fold and continuous bending according to customer drawings.
- Quality stability: High repeatability, suitable for mass production and high standards.
Our bending process, combined with laser cutting, enables the efficient shaping of intricate structures designed by our clients.
Sheet metal processing materials
To meet the needs of different industries and application scenarios, we support sheet metal processing of various metal materials. Different materials have their own mechanical properties, processing characteristics, and application advantages.
Commonly used for components requiring high corrosion resistance and strength, such as equipment housings and structural supports.
Lightweight and with good thermal conductivity, suitable for aviation, electronic equipment housings, etc.
Excellent electrical and thermal conductivity, suitable for electrical connection components and heat dissipation structures.
Highly economical, easy to weld and process, suitable for general structural parts and industrial applications.
We will provide processing suggestions for suitable materials based on the customer’s design requirements, and ensure that the material source is reliable and batches are consistent to guarantee subsequent processing and performance stability.
Tolerances of sheet metal processing services
In sheet metal fabrication, dimensional accuracy and consistency directly affect the assembly effect of parts and the performance of the final product. During laser cutting and bending processes, we employ standardized process control and inspection procedures to ensure stable and repeatable part dimensions, meeting the needs of most industrial applications.
The following are reference tolerance ranges for common sheet metal processing features (specific values may vary depending on material, thickness, and structural complexity):
| Processing characteristics | Reference tolerance |
|---|---|
| Laser cutting dimensions | ±0.20 mm |
| Aperture and Profile | ±0.20 mm |
| Bending angle | ±1.0° |
| Distance from bend to edge | ±0.25 mm |
| Flatness/Geometric Position | Based on structural and material assessment |
For precision sheet metal parts or projects with high assembly requirements, we can confirm key dimensions with customers during the order evaluation phase and focus on controlling key features. Our engineering team will review drawings before production to ensure design manufacturability, thereby reducing rework risks and improving delivery consistency.
Available surface treatments for metal sheets
To meet the diverse requirements of various applications regarding appearance, corrosion resistance, abrasion resistance, and functionality, we offer a range of common sheet metal surface treatment solutions. Surface treatment is typically performed after cutting and bending, significantly improving the lifespan and overall quality of parts.
- Standard : No additional chemical or mechanical treatment has been applied after machining; only chamfering and deburring have been performed to ensure safe machinability. Suitable for internal structural parts or applications where appearance requirements are not high.
- Bead blasting : A process that uses glass beads or other media to blast a surface, creating a uniform matte finish that helps to conceal minor scratches and improve the appearance of the assembly.
- Brushed : Using sandpaper or brushing equipment to create a linear texture by drawing the brush in a uniform direction, suitable for visual panels facing the end user.
- Brushed + Anodized Type II : Anodizing is performed after brushing to improve corrosion resistance and fine-tune the surface color while maintaining a good appearance.
- Bead blasting + Anodized Type II : Sandblasting followed by oxidation effectively improves the corrosion resistance of parts. Sharp edges are ground and deburred to ensure safe handling.
- Anodized Type III (Hardcoat) : Creates a thicker, harder oxide layer, improving wear resistance and environmental durability, suitable for high-wear parts.
- Powder coating : A tough protective layer is formed by electrostatic powder coating and high-temperature curing. It offers a variety of colors and textures, effectively improving corrosion resistance and overall appearance consistency.
- Black Oxide : Used for steel parts, it improves corrosion resistance and reduces light reflection through a chemical blackening process, and is often used for functional structural parts.
- Chromate conversion coating : Suitable for aluminum and its alloys, it improves corrosion resistance without affecting conductivity and provides a good base layer for subsequent coatings.
Our ordering process
To ensure the optimal balance between quality, delivery time, and cost for every sheet metal fabrication project, we employ an engineer-led ordering process. Unlike standardized online quotes, we prioritize direct communication with our clients to fully understand their design intent and practical application needs.
Our ordering process typically includes the following steps:
1. Submit design documents
Customers can submit CAD drawings (STEP, DXF, DWG, etc.) and basic requirements such as materials, quantity, and surface treatment via email, WhatsApp, or other commonly used communication methods.
2. Engineering evaluation
Our engineering team will review the drawings, assess material selection, structural feasibility, tolerance requirements, and processing techniques, and provide optimization suggestions when necessary.
3. Confirm the quotation
Based on thorough communication, we will provide a clear and actionable quotation and delivery timeline, suitable for sample, small batch, or continuous production orders.
4. Production and Quality
All sheet metal parts are completed in-house and undergo process checks and final inspections according to established standards to ensure that dimensions and appearance meet requirements.
5. Delivery
Once the parts are completed, arrange for packaging and shipping, and keep project records to facilitate subsequent repeat orders or long-term cooperation.
