Stainless steel + drop-resistant + encapsulated special material Vibration anti-loosening test: 50,000 times of vibration test, retention rate of thread locking force ≥95% Environmental tolerance test: After 50 cycles of high and low temperature from -20 ℃ to 60 ℃, the resin layer is free from cracking and falling off, and there is no rust in the salt spray test for 720 hours; Medical grade material + ultra-clean process burr-free polishing: ultrasonic + mechanical polishing in clean workshop, surface roughness Ra ≤ 0.2 μm Ultra-clean cleaning: residual contaminants ≤ 0.1 μg/cm ² Corrosion resistance: simulated medical disinfection environment, continuous disinfection 500 times, no rust, no coating peeling; titanium alloy material + wear-resistant process; wear-resistant performance: After 5 million times of continuous friction test, the wear loss of the coating is ≤ 0.002 mm, which is far below the industry standard Strength test: Shear strength ≥ 900MPa, tensile strength ≥ 250MPa, which can bear 1.5 times of the maximum load of the robot joint; titanium alloy + anti-falling coating Lightweight: 60% weight reduction compared with the traditional carbon steel screw Anti-fouling test: no adhesion after contact with engine oil and dust Strength test: tensile strength ≥ 240MPa, meeting the load requirements of UAV fuselage The endurance of the power-assisted UAV is increased by 15%; the high-strength aluminum alloy is used for the force-fastening aluminum rivet, and the deformation mechanical design of the rivet body and the ferrule is optimized. Through the precision cold heading and heat treatment process, it is ensured that the preset clamping force and shear strength are achieved after single-sided riveting. Application scenarios: circuit board, chip; SUS316 Dacromet combination screw, high-grade austenitic stainless steel SUS316 as the base material. Dacromet (zinc-aluminum coating) provides salt spray corrosion resistance (up to more than 1000 hours) far beyond that of traditional galvanizing, without the risk of hydrogen embrittlement, and is environmentally friendly and efficient.
