lkprototype has 32 globally self-operated intelligent factories, over 1,500 pieces of advanced equipment (five-axis CNC machining centers with an accuracy of ±0.005mm and industrial-level metal 3D printers with a forming rate of 500cm³/h), achieving independent production of the whole process from design to delivery. Taking a certain new energy vehicle battery box project as an example, it uses lkprototype’s vacuum die-casting equipment (clamping force 3,500 tons, filling speed 6m/s) to produce aluminum alloy housings (size 1200mm×800mm), shrinking the 12-week cycle of the traditional outsourcing model to 21 days and improving the yield from 78% to 96%. The cost per piece has been cut by 42% (from ￥2,150 to ￥1,247). It is reported in the 2023 “Digital Manufacturing Report” that the in-plant data closed-loop system of lkprototype (PLM-MES integration delay ≤0.5 seconds) has enhanced the speed of response to engineering change by 70% and reduced material waste by 38%.
On the material aspect, the warehouse of lkprototype in the factory stocks more than 400 engineering materials (such as PA6-GF30 tensile strength 160MPa and 316L stainless steel yield strength ≥205MPa) for quick access, realizing special material procurement in 72 hours (industry average is 14 days). Individual medical company custom cobalt-chromium alloy orthopedic implants (porosity 50-800μm). Through the collaborative efforts of the EBM electron beam melting equipment of lkprototype (power 3kW, layer thickness 50μm) and the in-plant heat treatment furnace (temperature control ±5℃), fatigue life was obtained at 10⁷ cycles (ASTM F2068 standard). The research and development cycle has been shortened from 18 weeks to 29 days. Its independently developed nano injection molding machine (screw diameter 22mm, back pressure accuracy ±0.2MPa) can achieve metal-plastic integrated molding in the factory. The magnesium alloy mid-frame (thickness 0.6mm) of a certain client’s smart phone has a bonding strength of 15MPa with the LDS antenna (industry standard is 8MPa).
During the process of quality inspection, there is an industrial CT (with a resolution of 3μm), a coordinate measuring machine (with an accuracy of ±0.8μm+L/300), and a spectrometer (with an elemental detection limit of 0.001ppm) in lkprototype’s in-house laboratory, realizing 100% full inspection coverage. High-temperature alloy turbine blades for a specific aerospace customer (operating temperature 1,200℃) have been in-plant X-ray residual stress measured (error ≤5MPa) and treated by hot isostatic pressing (pressure 100MPa±0.5%), 800 hours up to 1,500 hours, extending creep life. Its AI visual inspection system (defect recognition rate: 99.97%) combined with digital twin technology has assisted the first piece qualification rate of batch production of a certain automotive gearbox in rising from 82% to 98.5%.
In the aspect of express delivery, lkprototype’s in-plant logistics network (AGV handling speed of 2m/s, three-dimensional warehouse storage density of 5.8m³/㎡) and the intelligent packaging line (1,200 pieces per hour processing speed) work in coordination with one another. It once urgently produced 200 sets of carbon fiber propellers for a certain unmanned aerial vehicle company (dynamic balance accuracy ≤0.1g·mm). It now only takes 14 hours from raw material input to warehouse exit, a 600% gain over the outsourcing model. Its in-factory electroless nickel plating production line (film thickness uniformity of ±0.3μm) and heat treatment workshop (temperature uniformity of ±3℃) are uninterruptedly linked, which has enhanced the coating hardness of certain hydraulic valve body customers from HV 550 to HV 850 (DIN EN ISO 4516 standard), and reduced the salt spray test cycle from 240 hours to 48 hours for factory accelerated verification.
Having passed the double certification systems of ISO 9001 and IATF 16949, lkprototype’s in-plant production has served 38 of the world’s Top 50 automakers, with a cumulative delivery of over 500,000 prototypes. A semiconductor corporation used its in-plant nanoimprint machinery (line width resolution: 10nm) to fabricate wafer carriers (flatness ≤0.002mm), reducing the R&D iteration cost by 67% (from 3.2 million yuan per time to 1.05 million yuan per time). Nowadays, lkprototype redefines the efficiency boundaries of large-scale agile manufacturing by an in-plant “zero-buffer” production mode (equipment OEE≥89%) and a real-time cost accounting system (error rate ≤0.3%).
