About the Sheet Metal Fabrication Process for Kitchen Equipment:
1. Core Process
—Cutting Stage: A 12kW fiber laser cutting machine is used to process 40mm thick plates with an accuracy of ±0.1mm, making it particularly suitable for cutting complex contours of stainless steel kitchenware.
Shearing machines are used for straight-line cutting, and punching is suitable for mass production of standard parts.
—Forming Process: A 200-ton press brake achieves ultra-long bends of up to 4 meters, allowing for multi-pass shaping of stainless steel sheets within 6mm.
Commercial kitchen equipment typically uses 1.2-1.5mm stainless steel sheets for bending and forming.
—Welding Technology: TIG spot welding combined with laser welding/double-container welding increases weld strength by 30%, meeting the requirements of National Standard T19804.
Welding for food equipment must ensure contamination-free operation.
2. Material Selection Specifications
--Main Material: Commercial equipment typically uses 304 food-grade stainless steel (1.0-1.5mm thickness), while economy products utilize 0.6-1.0mm galvanized steel.
--Special Components: Water heater tanks utilize 304 stainless steel, and decorative strips utilize 6063-T5 aluminum alloy.
--Surface Treatment: Powder coating (30-80μm film thickness) or brushed/mirror polish. Must pass a 1000-hour salt spray test.
3. Quality Inspection System
--Dimensional Inspection: Coordinate measuring machines ensure mounting hole accuracy of ±0.05mm.
--Weld Inspection: X-ray inspection detects internal cracks.
--Coating Inspection: Paint film thickness gauges control within a 30-80μm range.
--Assembly Inspection: Laser scanners verify joint uniformity.
4. Typical Equipment Processing Cases
--Commercial Refrigerator: 0.6-1.0mm cold-rolled sheet metal bending, powder coating
--Disinfection Cabinet Housing: 1.2mm stainless steel laser cutting and bending, argon arc welding
--Coffee Machine Components: 0.8mm galvanized sheet metal stamping, brushed finish
