lkprototype’s vacuum casting service, featuring a precision control of ±0.1mm (industry average: ±0.3mm) and a silicone mold life of 50 times (industry average: 30 times), provides the fast turnaround of small-batch (10-500 pieces) orders (cycle 3-7 days, industry average: 14 days). For example, the bracelet shell (TPU 95A) of a certain smart wearable brand was processed by lkprototype’s vacuum casting process. The surface roughness Ra≤0.8μm (Ra≥1.6μm for ordinary injection molding), the tensile strength reached up to 45MPa (customer requirement ≥40MPa), and the unit price was reduced to 8.5 (23 pieces for mold opening injection molding). 78% of the trial production cost is saved.
Material compatibility comprises medical and industrial grades. lkprototype supports over 60 kinds of engineering materials (e.g., PC, ABS, PPA, Shore 80A-90D silicone), and its performance can be enhanced through nano-modification (e.g., 10% glass fiber addition). The sample of the artificial joint (PEEK+30%CF) of a certain medical client passed the ISO 10993 biocompatibility test (nickel precipitation amount ≤0.1μg/cm²), and compressive strength reached 220MPa (industrial standard was 180MPa), accelerating FDA approval (shortening the certification cycle by 45 days).
Its process and efficiency are remarkable. Its fully automatic deaeration system (vacuum degree ≤0.1mbar) shortens silicone curing time to 1.5 hours (4 hours for the traditional process), and mold replication accuracy is as high as 99.5% (key texture depth error ≤±0.02mm). One auto lighting company’s PC lampshade (400×200×5mm) was vacuum cast by lkprototype, with light transmittance as high as 92% (industry average: 85%), and there was no cracking in the temperature resistance test (cycle from -40°C to 120°C). The project development cycle was shortened to 5 days (21 days if traditional CNC processing is used).
The quality control is strict. The full inspection of every batch of products was carried out by using a three-coordinate measuring machine (accuracy: 0.005mm) and an industrial CT (defect detection resolution: 5μm). The dynamic balance test of a certain unmanned aerial vehicle propeller (PA6-GF30) showed that the mass distribution deviation was ≤0.1g·cm (the industry allowed ≤0.5g·cm), reducing the high-speed rotation failure risk by 93%.
Environmental protection and economy go hand in hand. lkprototype‘s water-based mold release agent (VOC emissions ≤50g/L) is REACH certified, and the recycling rate of silicone rubber is 85% (40% in the industry), and single-piece waste is decreased by 62%. The silicone earphone case (Shore 50A) of a certain consumer electronics firm reduced carbon emissions by 41% through the utilization of a closed-loop production system (EPD certification), and the marginal cost has been reduced to 1.2 per piece (2.8 for traditional processes).
The global supply chain offers delivery flexibility. lkprototype owns 12 globalized service centers across the world (China, the United States, Europe, etc.), with 72-hour global delivery (air freight $6.5/kg, 28% lower than that of competitors), and its raw material reserves guarantee over 200 SKUs (medical-grade silicone inventory guarantee rate 99%). A rush order (50 pieces) of hearing aid ear molds (medical silicone LSR 30) for a certain European customer was signed from China to Germany in just 58 hours (industry average is 120 hours) with a yield rate of 100%.
Customer cases attest to technical leadership. The touch panel of the dashboard in a certain electric vehicle brand (PMIA+ anti-fingerprint coating) has achieved a touch sensitivity error of ≤±2% through lkprototype vacuum casting (±5% for comparable products), and the conversion cycle of mass production has been reduced by 30 days. The special edition strap of a certain luxury brand (silicone Shore 70A) replicates the feel of crocodile skin (with a 97% degree of touch simulation). Price per piece is 15 (85 for handmade carved molds), and sales volume exceeded 10,000 in the first month of its launch.
Through the integration of “ultra-precision process × materials science × intelligent delivery”, lkprototype has redefined the standard for small-batch vacuum casting. In 2023, it supplied over 800,000 trial products to the medical, auto, and 3C industries, with a customer repurchase rate of 92% and a quality issue return rate of only 0.03% (0.5% in the industry).
