Jade gua sha board are becoming a health and beauty tool,which is loved by consumers around the world. However, how many precise processes are required from a rough natural raw stone to a warm and delicate jade gua sha tool? How do craftsmen transform the jade gifted by nature into a work of art ? Today, we will introduce you to the gua sha production process in the factory.
Rough Stone Slicing
The starting point of the life of each jade gua sha tool is hidden deep in the earth’s crust. The quality of the jade raw material directly determines the texture and energy characteristics of the finished product.
Our material selection team goes deep into the global jade mines all year round, from Chinese Hetian jade to Brazilian agate, from Burmese jade to New Zealand green jade mines. We strictly select high-quality raw stones with high purity, uniform color and no natural cracks.
Raw material standards:
- Transmittance test: Use professional instruments to detect the mineral structure of jade
- Energy property evaluation: Based on the theory of traditional Chinese medicine, jade varieties with warm and thermal conductivity are preferred;
- Environmental certification: All raw stones meet international mineral mining ethical standards and eliminate conflict mining raw materials.
In the slicing workshop, craftsmen use decades of experience and three-dimensional scanning technology to digitally model the natural texture of the raw stone. Through the water jet cutting process, the raw stone is cut into blanks with uniform thickness at the most reasonable angle.
Technical difficulties:
- It is necessary to accurately control the water flow pressure and cutting speed;
- It can avoid micro cracks in the jade due to high temperature and maximize the retention of the natural energy field of the jade.
Cleaning and shaping
After the masters cut, the surface of the jade blank is attached with mineral dust and cutting residues. After that, they need to enter the fully automatic ultrasonic cleaning line.
Under the combined action of 40kHz high-frequency vibration and plant-based environmentally friendly cleaning agents, the particles in the pores of the stone are completely removed, restoring the transparent luster of natural jade.
Highlights of the finalization process:
- CNC engraving machine: Based on hundreds of gua sha tool modeling templates in the ergonomic database. We carve the blanks into more than 20 international popular styles such as curved boards, fish-shaped boards, V-shaped boards, etc., with edge curvature accurate to 0.1 mm;
- Infrared positioning system: Real-time monitoring of the processing path, so that the outline of each blank is zero error with the design drawing;
- Waste recycling cycle: The jade powder produced by cutting is converted into a beauty mask additive through patented technology to achieve zero waste production.
Our gua sha factory are equipped with 2 fully automated production lines and 200 high-precision processing equipment. The daily processing capacity of the finalization process can exceed 50,000 pieces, and the product consistency reaches high standards.
Polishing of the blank
The finalized gua sha tool will enter the core polishing stage. Traditional jade polishing relies on manual touch, and our innovatively developed five-axis linkage robot arm polishing system converts manual polishing into quantifiable scientific and technological parameters.
Full analysis of the polishing process:
- Rough polishing: Use a 320-mesh diamond grinding wheel to remove surface knife marks and lay the foundation for smoothness;
- Medium polishing: Use a 3000-mesh resin grinding disc and a jade-specific coolant to gradually present a matte texture;
- Fine polishing: Use nano-grade cerium oxide polishing paste and sheepskin wheels for final mirror treatment to make the surface roughness ≤0.01μm;
- Energy activation: In an independent negative ion cabin, the molecular activity of jade is stimulated by sound wave vibrations of a specific frequency.
In the factory’s 2,000-square-meter intelligent polishing workshop, 200 self-developed centrifugal polishing barrels operate day and night, with a monthly production capacity of 500,000 pieces. Can you imagine? Each jade gua sha tool needs to undergo 12 hours of uninterrupted polishing before it can present a silky smooth touch under light detection.
Quality Control and Assembly
In our quality inspection laboratory, each gua sha tool must pass seven rigorous inspection levels:
- Defect detection: 4K microscopic camera scans the surface, and AI algorithm automatically identifies bubbles or cracks larger than 0.02mm;
- Dimension calibration: laser measuring instrument checks 56 key dimension parameters;
- Safety test: wear resistance test and edge passivation treatment simulating a 10-year use cycle;
- Energy detection: far-infrared emissivity meter verifies the thermal conductivity of jade.
