High-Quality Production Processes and Quality Control for Stainless Steel Floor Drains
1. Precision Material Selection
We use high-quality 304 stainless steel sheets, with nickel content ≥8% and chromium content ≥18%, ensuring corrosion resistance from the very beginning. The quality of the stainless steel sheet is crucial for the overall quality of the floor drain. Different manufacturing processes can lead to significant variations in both surface and intrinsic quality, as the quality of rollers and the rolling process influence the surface density and internal stress of the stainless steel sheets. Therefore, material selection involves not only spectroscopic analysis of the chemical composition but also consideration of the advanced manufacturing techniques employed in the production of the sheets. This guarantees the flatness of the product during shaping and the quality of surface treatment.
2. CNC Bending and Robotic Laser Welding
Utilizing a 200-ton CNC bending machine for precise shaping, with error control maintained within ±0.1mm, our high-precision equipment ensures the dimensions and appearance of the floor drain products are consistently reliable.
The robotic laser welding station guarantees the reliability of each weld, minimizing issues such as weak welds, incomplete welding, and unsightly seams.
3. Innovative Upgrades in Odor-Proof Technology
The odor-proof performance of a floor drain is one of the key indicators of product quality. Therefore, the design of the odor-proof structure and the quality of the plastic components are critical to the floor drain's capability to prevent odors. We select materials that resist aging and deformation, while the injection molds and processes greatly influence the quality of the components.
Gravity Dual-Seal Valve: Automatically closes to isolate sewer gases when dry, while also considering features that prevent blockages and facilitate easy cleaning for users.
4. Fine Surface Treatment
Brushed Finish: Eight processes create a delicate texture, achieving a scratch resistance index of 9H.
Electrolytic Polishing: Mirror-finish products undergo 16 hours of electrolytic treatment, enhancing gloss by 60%.
PVD Coating (Physical Vapor Deposition): In a vacuum environment, ions bombard the target material to deposit a nano-scale metal/ceramic film layer.
Wear resistance is improved by 3-5 times (hardness can reach HV800 and above), while corrosion resistance surpasses that of ordinary stainless steel (validated through a 96-hour acidic salt spray test).
5. Rigorous Quality Inspection System
Full-size three-coordinate detection
100,000 cycles of opening and closing durability testing
Third-party certifications for odor-proofing, drainage, and load-bearing capabilities.
