Core Conditions for Custom Sheet Metal Processing

Core Conditions for Custom Sheet Metal Processing

The core conditions for custom sheet metal processing are clearly defined requirements, provision of compliant drawings, matching the feasibility of processing techniques, and meeting both batch size and cost requirements.

I. Core Prerequisites: Clear Requirements and Provision of Drawings

Complete technical drawings are required, including 2D engineering drawings (with dimensions, tolerances, and material grades) or 3D models (STEP/IGS format preferred) to ensure clear processing benchmarks.

Clearly define core parameters: Product application, dimensional accuracy requirements (e.g., ±0.1mm/±0.5mm), surface treatment methods (spraying, galvanizing, anodizing, etc.), and assembly requirements.

Specify special requirements: Such as corrosion resistance, load-bearing capacity, and color difference standards to avoid rework later.

II. Material and Process Matching Conditions

Material selection must be compatible with the processing techniques: Commonly used sheet metal materials include cold-rolled steel, stainless steel, aluminum, and galvanized steel. Thickness must be clearly defined (standard 0.5-10mm; for extra-thick/extra-thin materials, confirm the manufacturer's equipment capabilities). Process Feasibility: Bending radius, opening size, welding position, etc., must comply with sheet metal processing specifications (e.g., bending radius not less than material thickness, small hole diameter not less than plate thickness). Complex structures require prior communication and optimization with the manufacturer.

III. Batch Size and Cost Matching Conditions

Batch Size Requirements: There is no mandatory minimum batch size for customization, but small batches (1-10 pieces) are more expensive, while large batches (100 pieces or more) can reduce the unit price. Some manufacturers support sampling (sampling fees apply).

Cost Consensus: A clear budget range must be defined. The manufacturer will provide a quote based on the complexity of the drawings, material prices, process difficulty, and surface treatment requirements. Processing will only begin after both parties confirm the quote and delivery cycle.

IV. Other Key Conditions

Delivery Cycle Matching: Delivery time must be agreed upon in advance. Sufficient production time must be reserved for complex products or during peak seasons (3-7 days for regular small batches, 7-15 days for large batches).

Quality Acceptance Standards: Clear acceptance criteria must be defined (e.g., inspection according to drawing dimensions, no scratches on the surface, smooth assembly, etc.). A quality agreement should be signed if necessary.
