LKprototype offers full-category material mixing customization services. Its R&D laboratory is capable of formulating over 200 material combinations, including engineering plastics (e.g., PA6+30%GF), metal matrix composites (e.g., AlSi10Mg+15%SiC), and elastomers (e.g., TPU+5%CNT), with a mixing ratio accuracy of ±0.3%. And it has passed 38 international certifications such as ISO 10993-5 (biocompatibility) and UL 94 V-0 (flammability resistance). It was commissioned by some medical device company in 2023 to develop antibacterial nylon (PA12+2% nano-silver). By optimizing the twin-screw extrusion process (temperature 220-260℃, shear rate 120s⁻¹), the antibacterial rate was increased to 99.99% (ASTM E2149 standard). Meanwhile, the tensile strength remains 65MPa±1.5MPa, and the cost is 18% less than that of pure PA12 material. In this project, LKprototype employs a melt flow index tester (MFI 10-300g/10min) to dynamically monitor the rheological property of the material, so that the batch density deviation is ≤0.5% (1.02-1.04g/cm³).
In terms of material performance customization, LKprototype can adjust main parameters such as thermal conductivity (0.1-50W/m·K) and dielectric constant (2.2-12.4@1MHz) according to customers’ requirements. For instance, one of the new energy automobile enterprises reduced the weight of the battery module bracket by 40% (from 1.2kg to 0.72kg) using its custom PEEK+25% ceramic fiber composite material (with the heat deformation temperature from 160℃ to 310℃). And maintain the dimensional change ≤0.02mm (CTE 3.5×10^-5/℃) in the cyclic test from -40℃ to 150℃. The design of the material was validated by DSC (Differential Scanning Calorimetry) to optimize the glass transition temperature (Tg) from 143 ° C to 158 ° C, which extends the lifespan of the component to 150,000 vibration cycles (SAE J2380 standard).
For food-grade and medical-grade composite materials, LKprototype’s compliant laboratory is equipped with HPLC (High Performance Liquid Chromatograph) and ICP-MS (Inductively coupled plasma Mass spectrometer) that can detect the concentration of migratory substances down to the 0.01ppm level. In a 2022 hybrid project of a baby products company, the team improved tear strength from 25kN/m to 38kN/m by adjusting the concentration of the vulcanizing agent (from 0.5% to 1.2%) and the mesh size of the fiber (from 200 mesh to 400 mesh), and passed FDA 21 CFR 177.2600 certification. VOC emission is below 0.1μg/g (0.5μg/g is the limit value). This material extends the mold life by 500,000 times (300,000 times for conventional silicone molds) and reduces the production unit cost by 22%.
In supply chain efficiency, LKprototype tailor-made material service has MOQ 1kg and realizes formula confirmation within 72 hours. In 2023, a certain aerospace company developed high-temperature resistant epoxy resin (TGDA+40%Al₂O₃). Through the adoption of its independently developed vacuum deaeration system (pressure 0.01Pa), the bubble rate was reduced from 0.8% to 0.05%, and the thermal conductivity after curing was maintained at 6.8W/m·K±2%. The flexural modulus is up to 12GPa (30% higher than that of products currently on the market). This material reduces the weight of the satellite bracket by 15% and Zero deformation is realized for orbital thermal cycling tests (-170 ° C to +120 ° C), which saves customers approximately $280,000 in launch costs.
