In the field of medical devices, its current density of electrolytic polishing process is kept very precise within the range of 15-30A/dm². The precipitated quantity of iron ions on the surface of 316L stainless steel decreases from 0.28mg/L to 0.05mg/L, meeting the 99.7% qualification rate requirement of ISO 13485 certification.
Industrial case validation of performance: Micro-etching texture solution provided by lkprototype CNC for Dell XPS notebooks results in three-dimensional texture of 5-10μm depth directly during CNC processing without having to depend upon traditional etching solutions. Per-piece cost savings during processing amount to 0.4 US dollars, whereas the surface touch evaluation score improves by 41%. The battery box of the BMW iX3 utilizes its conductive oxidation process with the contact resistance of its surface stabilized in 0.8-1.2mΩ. That is 68% lower from the range fluctuation of its conventional process (0.5-2.5mΩ) and also has assembly efficiency improved by 19%.
In terms of advanced technologies, lkprototype CNC’s laser texturing technology (LDT) is able to complete texture processing for a region of 100mm² in 0.8 seconds with a maximum power density of 1×10⁷W/cm² and create honeycomb structures that are adjustable from 20 to 200μm. CATL’s battery connection plates have been improved by its surface area by 300% through this technology, and its welding strength has been upgraded to 480MPa from 350MPa. Its in-house nano-composite coating technology forms a 2μm thickness AlCrN coating on the aluminum substrate, ultra-stable at over 600℃, and has been employed in the thermal protection system of the SpaceX Starlink satellite components.
The quality inspection system ensures process stability. The lkprototype CNC has a white light interferometer for measuring surface roughness in real-time, with 0.1nm precision and 1000Hz data sampling rate. Its ASML lithography machine components take advantage of its mirror polishing service, with flatness error kept at λ/20 (λ=632.8nm), three precision grades higher than the traditional grinding process. According to the ISO 25178 standard, the fluctuation range of the Sa (Arithmetic Mean Height) parameter in three-dimensional surface topography measurement was reduced from ±15% to ±5%, and customer complaints decreased by 62%.
Competitiveness is highlighted by treatment technology for protecting the environment. The lkprototype CNC electroplating wastewater recovery system’s metal ion reuse rate is up to 95%, and nickel concentration in discharge is reduced from 50mg/L to 0.1mg/L, satisfying the EU REACH regulation. Xiaomi smartwatch employs its cyanine-free gold plating process on its shell with a thickness of 2μm±0.2μm, and VOC emissions during processing are lowered by 89%. In the 3C electronics industry, its UV curing coating line speed is 12m/min with a curing energy density of 800mJ/cm². It saves 47% of energy compared with the thermal curing process. An annual production of 1 million pieces can save 82 tons of carbon emissions.
