In the field of modern architectural decoration, stainless steel products have become the preferred materials for important components such as stair handrails, screen partitions, and door and window frames due to their excellent corrosion resistance and decorative effects. This article systematically sorts out the standardized processing procedures and key technical points in the industry to help practitioners improve production efficiency and product quality.

I. Standard Processing Procedures

1. Drawing Deepening Design Stage

Based on the customer's drawings, 3D modeling is carried out, with the focus on the detailed design of the closing positions and connection structures. The technical drawings output by industrial-grade CAD software need to mark key parameters such as material thickness (usually 0.5 - 3 mm is selected) and bending radius.

2. Raw Material Selection and Cutting

The base material specifications are selected according to the application scenarios. 304 stainless steel is mostly used for interior decoration, and 316 material is recommended for coastal or highly corrosive areas. Laser cutting equipment can process plates with a thickness of 0.5 - 6 mm, and the slit is controlled within the range of 0.1 - 0.3 mm to ensure precise blanking.

3. Forming Process Implementation

(1) Bending Processing: Use a CNC bending machine to complete the forming of corner bends, and focus on controlling the bending coefficient compensation for plates with a thickness of 1.0 - 1.5 mm.

(2) Stamping Forming: Suitable for the production of complex relief patterns, which requires multiple - process processing with the cooperation of molds.

(3) Pipe Bending Process: When processing pipes with a diameter of 6 - 100 mm, the deformation of the pipe wall should be controlled within 5%.

4. Welding and Finishing Processes

Tungsten inert gas welding is used for seam welding, and the penetration depth of the weld should reach more than 30% of the base material thickness. After welding, rough grinding is carried out by a belt sander, and then stepped polishing is carried out using 400# - 3000# grinding wheels in sequence.

5. Surface Decoration Treatment Technologies

(1) Wire Drawing Process: Use abrasives with a grit size of 120 - 240 to create continuous patterns.

(2) Mirror Polishing: An ultra - smooth surface with Ra ≤ 0.05μm can be achieved through 8 - 12 processes.

(3) Coating Process: PVD vacuum coating can present more than 6 kinds of metal colors such as titanium gold and champagne gold.

6. Quality Control System

A three - level inspection standard is established for dimensional deviation (±0.5 mm), surface finish (no scratches larger than 0.2 mm), and structural stability (load - bearing test). The finished products need to pass a 48 - hour salt spray test to verify their anti - rust performance.

 

II. Key Technical Control Points

1. Welding Quality Assurance

Strictly control the purity of the shielding gas (argon purity ≥ 99.99%), set the welding current according to the ratio of 1A/0.1 mm of the plate thickness, and implement the double - sided welding process for workpieces with a thickness of more than 1.5 mm.

2. Anti - deformation Control

(1) Material Pretreatment: Stress - relieving annealing is carried out before processing.

(2) Processing Technology Optimization: Use the multi - point bending method for long - sized workpieces.

(3) Clamping Control: Use vacuum suction cups to fix thin - plate parts.

3. Environmental - friendly Production Measures

Configure a circulating water cooling system to reduce water consumption. The welding fumes are treated by a cartridge - type purification device, and the classified recovery rate of metal waste should reach more than 95%.

4. Installation Cooperation Points

Provide standard large - scale node drawings for the construction party, control the positioning error of embedded parts within ±2 mm, and set the expansion joint spacing according to the standard of 0.8 - 1.2 mm/meter.

 

Mastering the above - mentioned processing specifications and process standards can ensure that stainless steel decorative products meet the long - term use requirements of more than ten years while maintaining their artistic beauty. It is recommended that production enterprises establish a whole - process quality control system from raw material procurement to on - site installation and continuously optimize processing parameters to meet the diversified market demands.
