The "Multi-Process Integrated Fine Handmade Sink Production Line" takes process integration and meticulous craftsmanship as its core advantages to create high-quality handmade sink products. Breaking through the traditional decentralized processing mode, the production line integrates key procedures such as raw material pretreatment, precise shaping, fine polishing, anti-fouling treatment, and quality inspection into an integrated workflow, significantly improving production efficiency and quality control stability.

Adhering to the core of "fine handcraftsmanship", each sink is fully controlled by senior artisans throughout the process: laser positioning-assisted manual cutting ensures contour accuracy reaches 0.1mm; curved corners undergo 36 manual polishing steps to achieve seamless and smooth transitions; scratch-resistant coatings are evenly applied by hand and cured at constant temperature to form a long-lasting protective layer.

Through process integration, the production line precisely controls the parameter connection between each link. For example, the stress relief process after shaping seamlessly coordinates with subsequent polishing procedures, avoiding dimensional deviation issues common in traditional production. It also retains the flexibility of manual customization, supporting adjustments to sink depth, basin partitioning, and drainage structure according to needs. Each product must pass 12 rigorous tests, covering everything from load-bearing tests to anti-leakage experiments, ensuring both practical performance and exquisite texture.
