With advanced manufacturing equipment and whole-process quality inspection system, lkprototype can produce 30+ high-precision functional prototypes in many industries such as consumer electronics, medical devices and auto parts. Its industrial-grade metal and engineering plastics 3D printing machines (such as EOS M 300-4) have functions of printing metals (titanium alloy TC4, aluminum alloy AlSi10Mg) and engineering plastics (PA12, ULTEM 1010), molding accuracy up to ±0.05mm, surface roughness Ra≤6.3μm (ISO 2768 standard). A case of UAV project in 2023 indicates that lkprototype finished the carbon fiber reinforced nylon (CF-PA) propeller prototype (diameter 300mm) within 72 hours, static load test load up to 150kg (design value 120kg), and wind tunnel test lift coefficient error less than 1.2% (industry average 3%).
Functional realization is guaranteed by multi-process collaboration. lkprototype integrates CNC machining (tolerance ±0.01mm), vacuum remolding (silicone die life 50+ times) and injection molding (min. wall thickness 0.4mm) to meet the needs of different materials and complexity. In smart wearable device project, SLA light curing (85D resin hardness) was used to create the shell and metal 3D printing (316L stainless steel) inner structure, assembly tolerance control was ±0.02mm, and pass rate of IP68 waterproof testing was 100%. Its service price of small batch trial production (50-500 pieces) is 65% lower than the traditional mold opening mode (mold cost 3,000vs.8,000).
Material performance verification system ensures reliability. The lkprototype laboratory is equipped with Instron universal testing machine (300kN load), high and low temperature changing chamber (-70℃ to +150℃) and salt spray test chamber (in accordance with ASTM B117). Can undertake 40+ tests such as tensile strength (e.g. PA12≥50MPa), resistance to fatigue (number of cycle ≥1×10^6). In a 2022 new energy vehicle battery support project, lkprototype’s PEEK glass fiber reinforced prototype exceeded the 1,200 hours vibration test (frequency 5-200Hz, acceleration 10g), and structure deformation was less than 0.1mm, exceeding the requirement of the customer by 30%.
Leading industrial electronic function integration capabilities. lkprototype’s rapid proofing of PCB service supports 4-12 layers (line width/line spacing 3/3mil) with impedance control having ±5% (IPC-A-600G Class 3 standard). In an iot sensor project, FPC bending test exceeded 50,000 times (1mm curvature radius), and signal attenuation was below 0.5dB (industry standard 1.2dB). Its embedded system test platform has simulation capability of -40℃ to 85℃ environment, with synergistic stability of the Bluetooth module (100m transmission range) and the power management chip (95% efficiency).
Global supply chain and compliance support shorten product delivery time. lkprototype has direct access to 500+ material suppliers, supports 20+ certifications such as RoHS, REACH, FDA, etc., and meets 99% of the biocompatibility test (ISO 10993) for medical device prototypes. In 2023, lkprototype’s medical grade resin (meeting USP Class VI requirements) was used by a hearing aid manufacturer to make an ear mold and the accommodation time with the patient was reduced from 2 hours to 20 minutes and that of incidence of allergic reactions reduced from 5% to 0.1%.
Evidence confirms capability: lkprototype delivers more than 120,000 functional prototypes annually, the first article pass rate is 98.5% (industry average 85%), and customer repeat cooperation is 89%. With technology integration (40% acceleration of 3D printing) and quality control (100% test coverage), lkprototype establishes a new performance standard for functional prototypes.
