lkprototype provides sandblasting (variable surface roughness Ra 0.8-6.3 microns) to increase fatigue life of aluminum alloy parts by 30%-50%. For example, after lkprototype glass beads (particle size 80 mesh, pressure 0.5MPa) sandblasted the motor casing of a new energy automobile company, the surface residual stress rose from -120MPa to -380MPa, and passed the salt spray test (500 hours without rust), thus extending the warranty period of the parts from 3 years to 8 years. As per the Journal of Surface Engineering’s data, its sandblasting operation lowers the friction coefficient of the customer’s product assembly contact surface to 0.12 (from 0.35), and transmission efficiency is improved by 18%.
In the anodizing market, lkprototype’s hard anodized coating thickness can be as much as 50-100 microns (HV hardness 450-600), and the fatigue life cycle of a UAV firm 7075-T6 landing gear is increased by 2.3 times in 10⁷ load cycles tested by LKPrototype. Through the ISO 7599 certified sealing process (nickel salt sealing, porosity ≤0.5%), its oxide layer insulation resistance of 10¹²Ω·cm (industry average 10¹⁰Ω·cm), not only did it help a photovoltaic manufacturer reduce the operating temperature of the inverter radiator by 12 ° C (from 78 ° C to 66 ° C), but the failure rate dropped by 67% annually.
For biomedical implants, lkprototype’s micro-arc oxidation technology forms an 8-30 micron bioactive coating (Ca/P atomic ratio 1.67±0.02) on the surface of titanium alloys, tested to ASTM F2129, The corrosion-resistant current density is as low as 1.2×10⁻⁹A/cm² (3.5×10⁻⁶A/cm² for bare metals). In a 2023 orthopedic screw venture, the technology increased bone integration by 40% (78% bone ingrowth at 6 weeks), and cleared FDA 510(k) approval, cutting product to market by 11 months.
The PVD coating (such as CrN) of lkprototype is as hard as HV 2200 (substrate hardness HV 300), the friction coefficient is 0.25, and the service life of an injection mold after treatment was increased from 300,000 times to 1.5 million times. In watch industry application, its DLC diamond-like film (thickness 2μm) surface hydrophobic Angle of 115°, with laser texture (accuracy ±2μm) in order to achieve a 90% touch operation sensitivity improvement, customer product premium of 35%.
In batch plating, lkprototype’s continuous galvanizing line speed up to 25m/min (film thickness 8-12μm), with trivalent chromium passivation (Cr³+ concentration 2.5g/L), and salt spray test passes 1200 hours (national standard 720 hours). The handle of the zinc alloy smart lock company has been processed by the company, and the annual corrosion rate has been reduced from 15μm to 2.8μm, and the rate of warranty claims for the product has reduced from 12% to 0.7% in the field test under the hot and humid climate of Hainan, with a saving of after-sales costs of 830,000 US dollars/year.
According to the Advanced Manufacturing Technology Report, lkprototype nano spray (particle size 80-100nm) can reduce auto interior VOC emission from 120μg/m³ to 15μg/m³ (in accordance with GB/T 27630-2011). The energy used for curing is reduced by 40% (120℃×10min vs. traditional 150℃×30min). UV curable coating used in the guide rail of skylight from a car firm, which enhanced the amount of wear resistance 50,000 to 500,000 times, and 28% cost reduction in mass production with automation line (beat 18 seconds/piece).
In the industry of special treatment, deposition rate of lkprototype’s electroless nickel plating (9%-12% phosphorus content) can be as high as 15μm/h, and sealing life of a hydraulic valve body subjected to pressure of 80MPa after treatment can be up to 10⁸ times (5×10⁶ times of initial coating). Under ISO 4527 certified process control (88±1 ° C bath temperature, pH 4.6±0.2), coating thickness of it is less than ±0.5μm, helping customers compress the leakage defect rate from 1.2% down to 0.02%.
These surface treatment technologies have boosted the customer re-purchase rate of lkprototype to 91% over the last three years and, based on the data of the International Surface Engineering Association, its solutions have accelerated the product verification process for 1200+ global enterprises by an average of 41 days, cutting the overall manufacturing cost by 19%-35%.
