Finishing
Anodizing (corrosion resistance + appearance)
Suitable for shell parts and cosmetic parts; can improve corrosion resistance and wear resistance. When you are sensitive to color and appearance consistency, it is recommended to provide reference samples or clarify color number and gloss targets.
Powder coating (strong coverage)
Suitable for batch cosmetic parts and durable surface requirements; good coverage and multiple color choices. Please describe the appearance and acceptable corner powder standards in the comments.
Spray painting (color and texture control)
More suitable for projects with clear goals for color/gloss (matte/high gloss); it is recommended to provide reference pictures or clarify color numbers and appearance standards.
Screen printing (logo and scale)
Suitable for logos, panel text, scales and operation marks; please provide vector files and location dimensions, and confirm the process sequence requirements for powder coating/painting/anodizing.
Laser engraving (durable marking)
Suitable for QR codes, serial numbers, nameplate information and wear-resistant markings; content, size, position and contrast targets (depending on surface finishing) are recommended.
Why Choose Aluminum Alloy_AL5052 (Sheet Metal Fabrication)
Corrosion resistance is more friendly
Suitable for common environmental usage scenarios such as chassis casings, covers, brackets, etc.; with anodizing/spray coating solutions, durability can be further improved.
Lightweight (more suitable for shells and structural parts)
Low density, easy to achieve lightweight; common in shell parts and sheet metal structural parts, taking into account both cost and performance.
Various appearance and surface finishing options
It supports sandblasting, anodizing, powder coating, painting, screen printing and laser engraving, and is suitable for projects that require appearance consistency, logo and brand presentation.
High delivery efficiency (suitable for prototypes and small batches)
The sheet metal route is mature and suitable for prototype iteration and small and medium-volume delivery; DFM feedback is provided to help reduce rework and assembly risks.
Recommended Applications
- Shell/Panel/Chassis: Sheet metal parts that are more sensitive to appearance, weight and corrosion resistance
- Lightweight structural parts:Common sheet metal structures such as brackets, covers, and protective covers
- Requires surface finishing: Anodizing, powder coating, painting + screen printing/laser engraving marking requirements
- Prototype and functional validation: Hope to quickly obtain assembly-ready and verifiable sheet metal parts
It is not recommended to use it directly (it is recommended to change materials/change routes)
- Higher strength limit: If strength is the primary goal, higher strength aluminum alloys can be evaluated or other material systems can be used
- High temperature resistance/high wear resistance: When near a heat source or wear and tear conditions are obvious, it is recommended to evaluate more temperature-resistant/wear-resistant materials
- Extremely demanding on appearance: It is recommended to clarify the color difference/gloss/scratch level in the remarks, and evaluate the process window and achievability
- The structure is better than sheet metal: If the geometry is more suitable for CNC/die casting/injection molding, etc., it is recommended to reselect the route based on target cost and performance.
Design and DFM Guidelines
- Plate thickness and strength: Plate thickness directly determines rigidity, bending feasibility and cost; if there are force/assembly requirements, please specify the plate thickness and key force direction in the drawings.
- The relationship between bending and hole position: Holes, grooves, and cuts close to the bending edge will affect the forming stability and appearance; it is recommended to reserve reasonable margins and adjust the structure or process sequence if necessary.
- Mounting holes and datum: If you need positioning assembly/alignment, please provide 2D markings or remarks on key hole locations, tolerances and datum systems to facilitate one-time quote.
- Appearance surface definition: The appearance consistency and corner transition standards of powder coating/painting/anodizing need to be clarified in advance; it is recommended to mark "appearance side/non-appearance side".
- Logo process: For screen printing/laser engraving, please provide artwork, size and location; if combined with powder coating/painting/anodizing, please indicate the priority and contrast requirements in the remarks.
