lkprototype’s surface treatment technology controls the anodic oxidation thickness tolerance of aluminum alloy within ±2μm, and improves the film uniformity to 98.5% through the closed-loop PH regulation system (accuracy ±0.05) and current density optimizing algorithm (fluctuation <±3%), and the salt spray test lifespan is more than 2000 hours (ISO 9227 standard). A car parts example shows that the surface hardness of the micro-arc oxidation-treated magnesium alloy is up to 1800HV, friction coefficient drops to 0.15, and the wear rate reduces by 72% compared to the traditional coating, which successfully passed the Volkswagen TL226 standard certification.
In the field of heat treatment, the precision of vacuum quenching furnace temperature control of lkprototype can be up to ±1.5℃, and β phase transition temperature of TC4 titanium alloy control error is less than ±3℃ when using nitrogen partial pressure regulation system (fluctuation <0.005MPa). Following solution + aging treatment, the tensile strength of an aerospace fastener increased from 1100MPa to 1250MPa, and the fatigue life cycles were raised from 2.1×10^6 to 3.8×10^6 (ASTM E466 standard test). Its continuous tempering line can make 800 pieces per hour (size φ20×100mm), grain size is controlled in ASTM 10-12, hardness dispersion σ=0.8HRC.
During the sandblasting process, lkprototype’s smart parameter matching technology pressed the surface roughness Ra value deviation to ±0.1μm. By reverse engineering of the spray gun path via 3D scanning, the contour matching rate of a medical device housing reached 99.2%, and the white corundum abrasive utilization rate increased to 92% (traditional process only 65%). Its closed-loop abrasive recovery system reduces consumable waste by 30% and, when combined with a 0.5μm precision laser particle size analyzer, delivers a uniform abrasive particle size distribution D50 of 120±5μm (ISO 8503-2 standard).
For precision cleaning, lkprototype’s supercritical CO₂ cleaning technology delivers 99.998% cleanliness (ISO 14644-1 Class 4) with a residue concentration of <0.1μg/cm² (IEST-STD-CC1246E). An optical lens cleaning case shows that under the condition of 40 ° C /10MPa, the Angle of contact surface is reduced from 72° to 5°, cleanliness meets the NASA MSFC-3688 space requirement, and cleaning cycle can be shortened to 18 minutes (traditional ultrasonic cleaning for 45 minutes). Its wastewater treatment plant reduces COD from 5,000 mg/L to 50mg/L by membrane separation technology, and the water reuse rate can reach up to 95%.
In additive manufacturing post processing, lkprototype electro-polishing machine reduced the inner surface roughness of 316L stainless steel from Ra 12.6μm to 0.8μm, and enhanced the flow coefficient by 23% (ISO 1217 standard test). HIP isostatic pressing of a rocket engine fuel nozzle (1200℃/150MPa) reduced porosity from 0.3% to 0.02% and increased high temperature endurance strength by 41% (AMS 2750). Its automatic support removal system increases the removal efficiency of titanium alloy components to 45 seconds/piece (300 seconds manually) with a surface damage rate of <0.01% using a force-feedback robot arm.
For particular requirements, lkprototype’s laser texturing technology also attained a machining accuracy of 0.02mm, the tactile friction coefficient of the interior of a car is modulated from 0.35 to 0.28±0.02, and pattern depth consistency is 98.5% (DIN 4768 standard). In PVD coating applications, its magnetron sputtering system improves film thickness uniformity to ±5% (±15% using traditional DC sputtering) and diamond-like coating hardness of a watch shell to 3800HV, reducing the wear rate by 62% compared to traditional PVD (ASTM G99 test).
With combined MES system, lkprototype realizes the whole process traceability, from the sand blasting pressure (0.6±0.02MPa) to real-time monitoring of 287 parameters of the heat treatment furnace oxygen content (<10ppm), to lower the post-treatment rejection rate from industry average 1.2% to 0.18%. A medical implant project obtained FDA 21 CFR Part 820 certification with this system and reduced the product time-to-market by 40%. These facts verify lkprototype’s technological superiority in the field of post-processing.
