In the automotive industry, lkprototype has achieved the 64-chamber mold filling balance error of ±1.5% through the application of a multi-chamber hot runner system and Moldflow analysis technology, far lower than the industry standard of ±5%. To illustrate, one foreign automaker commissioned it to design a high-gloss, traceless bumper mold. By applying the variable mold temperature technology (RHCM), the surface roughness Ra value was reduced from 0.8μm to 0.2μm, the yield rate was increased from 78% to 99%, the unit price was reduced by 40%, and the delivery cycle was reduced to 22 days (while the traditional process required 45 days). In the medical field, the microcellular foaming mold that lkprototype developed for the world’s Top 5 insulin pen supplier achieves an accuracy of ±0.02mm in wall thickness, the pore diameter is controlled at 50±5μm, the weight is reduced by 30%, and it has reached ISO 13485 certification at the same time, with an annual production capacity of over 5 million pieces.
Responding to the miniaturization needs of the consumer electronics sector, lkprototype’s nanoscale precision mold technology has been achieved exceptionally well. A leading mobile phone brand’s Type-C interface waterproof plug mold is made of high-hardness S136 steel (HRC 52) and mirror polishing process. Insertion and removal life has been increased from 5,000 times to 100,000 times, and the tolerance zone has been narrowed from ±0.1mm to ±0.01mm. Through the intelligent temperature control system, the temperature among the mold cavity is in the range of ±0.5℃, and the melt flow velocity deviation rate is less than 2%, which has improved the qualified rate of 0.3mm thin-walled structure formation from 65% to 98%. In the UAV sector, its carbon fiber reinforced PA6 propeller mold it developed, through gas-assisted forming technology (GAIM), reduces the dispersion of the fiber orientation to 8% (industry average: 25%), increases the flexural strength to 320MPa, and reduces the vibration peak by 40dB.
In super-large molds, lkprototype’s modular design method significantly improves efficiency. For the 8,000-ton injection molding machine refrigerator door panel mold of a home appliance company (projected area: 4.2m²), through the real-time monitoring and compensation system of in-mold stress, the deformation was reduced from 1.2mm to 0.15mm, the cooling time was shortened to 30%, and the energy consumption was saved by 25kW·h per piece. It is applied in the aerospace field, and the PEEK composite material satellite bracket mold it makes adopts conformal waterway technology, which improves the cooling efficiency by 70%, optimizes the crystallinity from 45% to 82%, and controls the dimensional stability error of the part in the temperature range of -180℃ to 300℃ within less than 0.005%.

lkprototype’s intelligent production system is also a demonstration of its innovation. In a certain new energy battery cover plate mold project, through the application of AI-based process parameter optimization (for example, holding pressure ±0.5Bar and screw speed ±2rpm), the weld line strength was increased from 18MPa to 35MPa and the defect rate was reduced from 12% to 0.3%. Its independently designed mold health monitoring system can collect over 2,000 sensors’ information in real time (like mold temperature, pressure and displacement), with the precision of ±8 hours in predicting maintenance cycles, and extending the mold life from 500,000 times to 2 million times. In the packaging industry, one of the biggest daily chemical companies’ multi-layer co-extruded bottle cap molds has reduced the production cycle from 18 seconds per piece to 9 seconds through the application of lkprototype’s die stacking technology, increased material usage by 22%, and saved over 800 tons of PET raw material annually.
Even more notable is that lkprototype’s “zero minimum order quantity” business model has broken through industry constraints. 2023 statistics show that its proportion of small-batch complicated mold orders (5-50 pieces) reached 63%, and the average unit price was 55% lower than the conventional model. For instance, one start-up medical device company, through its quick mold service, reduced the development cost of prototypes from $120,000 to $38,000 and finished 100,000 sterilization cycle tests required for FDA certification, advancing the product launch time by six months. Through continuous innovation and data-driven approach, lkprototype has supplied over 5,800 sets of high-complexity molds to over 1,200 enterprises around the world, with a 91% customer repurchase rate, once again setting the boundaries of precision production.
