Xianjing Polishing: Tech Innovator of Walnut Shell Abrasives, Setting New Benchmarks for Green Precision Craftsmanship

A century-old natural gift, elevated by today’s intelligent manufacturing — Returning physical polishing to its purity

Guangdong Xianjing Polishing Industrial Technology Co., Ltd. builds on natural wisdom to innovate traditional walnut shell abrasive processes, launching medical-grade refined walnut shell abrasives. Specifically crafted for medical devices, high-end jewelry, and aerospace precision components, these abrasives achieve Ra0.1μm-level high-gloss polishing through pure physical modification technology (no chemical coatings, no heavy metal additives). While retaining 100% biocompatibility and eco-friendly properties, they infuse industrial manufacturing with the power of nature.

● Dual Core Breakthroughs in Natural Precision Craftsmanship

Cell-Level Structural Remodeling

• Steam Explosion Nano-Activation: Breaking through traditional crushing processes, high-temperature and high-pressure steam opens the fiber pores of walnut shells, increasing hardness to Mohs 7.2 (200% higher than ordinary walnut shell abrasives). Cutting force reaches the root of micron-level burrs.

• Ultra-Tough Honeycomb Structure: The natural porous structure absorbs debris, avoiding secondary scratches on workpieces. Polishing uniformity is improved by 50%, making it particularly suitable for life science components such as titanium alloy joint prostheses and endoscope tubes.

Circular Ecology Revolution

• 12-Cycle Service Life: Exclusive surface crystallization technology increases fracture resistance by 300%, allowing a single batch of abrasives to be reused 12 times. Costs are 70% lower than metal abrasives.

• Carbon-Negative Manufacturing Loop:
  ▶ Raw materials sourced from organic walnut forests in the Qinba Mountains, with each ton of abrasives sequestering 0.8 tons of carbon.
  ▶ Waste abrasives naturally degrade within 30 days, with zero heavy metal residues in soil, passing medical certification.

● Industry Substitution Storm

● Three Natural Tech Barriers for Choosing Xianjing

Trillion-Level Resource Control:

▶ Signed contracts for 100,000 mu of organic walnut forests in the Qinba Mountains, with raw material pesticide residues<0.01ppm.
▶ Established the world’s first walnut shell abrasive gene bank, with precise grading of hardness and particle size.

Military-Grade Quality Control Standards:

▶ 36-stage screening process (particle size optional from 50-800 mesh), with impurity rate<0.001%.
▶ Produced in 100,000-class clean workshops, with microbial control exceeding standards.

Circular Economy Ecology:

▶ Old abrasive recycling program: Free exchange of old materials for new ones.
▶ Carbon credit empowerment: 0.05 tons of CCER carbon allowances per ton of abrasives, reducing ESG compliance costs.
