For medical device clients, Xiangchu’s antimicrobial LSR formulations have passed ISO 10993-5 cytotoxicity testing and achieve a 99.9% reduction rate against *E. coli* and *S. aureus*, meeting the strict requirements of Class III medical device applications. For electric vehicle (EV) manufacturers, its high-temperature resistant LSR maintains 92% of its original mechanical properties after 1,000 hours of aging at 250°C, outperforming standard LSR which typically retains only 70% of properties under the same conditions.
Xiangchu operates 42 sets of fully automated LSR injection molding machines with clamping forces ranging from 55 tons to 350 tons, equipped with closed-loop dosing systems that maintain a 1:1 mixing ratio of LSR base and curing agent with ±0.1% accuracy. This level of precision ensures consistent part quality even for high-volume runs of micro-sized components with tolerances as tight as ±0.005 mm.
The company’s quality control workflow integrates multiple non-destructive testing (NDT) technologies to eliminate defective parts before shipment:
For a recent medical client producing insulin pump reservoir seals, Xiangchu achieved a 0.3 ppm defect rate over a 2 million part production run, exceeding the client’s required 1 ppm defect threshold and reducing their incoming inspection costs by 60%.
Unlike generalist silicone processors that offer one-size-fits-all services, Xiangchu has developed deep vertical expertise in four high-demand industries, with dedicated engineering teams for each sector to address unique regulatory, performance, and design requirements. This specialization reduces the learning curve for new clients and ensures that LSR components are optimized for their intended use case from the initial design phase.
The medical device sector has the strictest requirements for LSR components, with compliance to ISO 13485 quality management systems and biocompatibility standards as non-negotiable prerequisites. Xiangchu holds ISO 13485:2016 certification and has 8 years of experience producing Class II and Class III medical LSR parts, including respiratory device components, surgical instrument accessories, and implantable short-term contact components.
The company provides end-to-end support for medical device OEMs, including:
In 2022, Xiangchu partnered with a Wuhan-based medical device startup to develop a custom LSR mask cushion for a portable CPAP device. The engineering team adjusted the LSR formulation to reduce skin irritation, optimized the mold design to eliminate sharp edges, and completed production validation in 12 weeks, 3 weeks ahead of the client’s clinical trial timeline. The product has since obtained NMPA approval and is now in mass production at 150,000 units per month.
The global automotive LSR market is projected to reach $2.8 billion by 2027, driven by the expansion of electric vehicles and advanced driver-assistance systems (ADAS), per Grand View Research. Xiangchu has invested heavily in automotive-specific LSR processing capabilities, holding IATF 16949:2016 certification and supplying 17 automotive OEMs and tier 1 suppliers in Central China.
