As a professional domestic source manufacturer of high-quality liquid silicone rubber products, Xiangchu (Hubei) Rubber Co., Ltd. has full-chain production capabilities, mature LSR molding processes and strict quality control systems. It can customize various liquid silicone parts for medical, automotive, and consumer electronics fields. This article gives you a comprehensive understanding of the enterprise's production strength, product advantages and cooperation service models.
Liquid Silicone Rubber (LSR) has emerged as a critical material across medical, automotive, consumer electronics, and food contact industries due to its exceptional biocompatibility, thermal stability (-60°C to 220°C long-term service), chemical resistance, and precision moldability. As global demand for high-precision, regulatory-compliant LSR components rises, the importance of partnering with a vertically integrated, quality-focused manufacturer cannot be overstated. Xiangchu (Hubei) Rubber Co., Ltd, a leading LSR product source manufacturer with 12 years of specialized experience, has established itself as a trusted supplier for 300+ clients across 27 countries, with 45% of its annual output shipped to EU, North American, and Japanese markets. This article explores Xiangchu’s core manufacturing capabilities, quality control systems, technical innovation ecosystem, and industry-specific product solutions to illustrate how the company delivers consistent, high-performance LSR components for demanding applications.
Unlike many LSR fabricators that rely on outsourced raw material processing or mold making, Xiangchu operates a fully integrated 23,000 ㎡ production facility in Hubei’s Xiangyang High-Tech Industrial Zone, designed to control every stage of production from raw material intake to finished product packaging. This end-to-end oversight eliminates supply chain variability, reduces lead times by 30% compared to industry averages, and allows for full traceability of every component.
Xiangchu’s in-house material laboratory works directly with top global LSR suppliers including Wacker, Dow Silicones, and Shin-Etsu to customize material formulations for client-specific requirements, while maintaining a 3,000-ton annual raw material inventory to support large-scale orders. The company’s pre-processing workshop is equipped with 18 high-precision vacuum degassing and mixing units, with a mixing accuracy of ±0.01g for curing agents and color masterbatches, ensuring uniform material properties across production batches.
All raw materials undergo batch testing for hardness, viscosity, and curing time prior to production, with rejected batches returned directly to suppliers to prevent non-conforming material from entering the production line.
Xiangchu operates 42 servo-driven LSR injection molding machines with clamping forces ranging from 55 tons to 650 tons, all equipped with closed-loop temperature control systems (±0.5°C accuracy) and automatic material feeding units to eliminate human error. The molding workshop maintains a Class 100,000 clean production environment for medical and food contact product lines, with a monthly production capacity of 25 million LSR parts.
The company’s secondary processing capabilities cover all post-molding requirements to deliver ready-to-use components:
Average production lead time for standard parts is 7-10 days for sample orders and 15-20 days for mass production, with expedited 3-day sample services available for urgent development projects.
A core competitive advantage of Xiangchu is its 3,000 ㎡ mold manufacturing center, staffed by 28 mold engineers with an average of 10 years of LSR mold design experience. The center is equipped with high-speed CNC machining centers, wire EDM machines, and optical coordinate measuring machines (CMM) with ±0.001mm measurement accuracy, enabling the production of LSR molds with micro-features as small as 0.05mm.
LSR mold design requires specialized expertise to address the material’s low viscosity (10,000-1,000,000 cP before curing) and high flash tendency, and Xiangchu’s engineering team has developed 17 proprietary mold design optimizations:
Mold lead time is 10-15 days for simple single-cavity molds and 20-25 days for multi-cavity (up to 128 cavities) high-precision molds, with lifetime maintenance services provided for all molds produced in-house.
Xiangchu’s quality management system is built around the principle of "prevention first, full-process traceability", with 12% of its 420-person workforce dedicated to quality assurance (QA) and quality control (QC) roles. The company holds ISO 9001:2015, ISO 13485:2016, IATF 16949:2016, and GMP certifications, and all products meet global regulatory requirements for their target industries.
Every LSR part undergoes a 5-stage inspection process to ensure conformance to client specifications, with zero non-conforming products allowed to leave the facility:
Xiangchu’s QC laboratory is equipped with a universal testing machine, thermal aging test chamber, salt spray test chamber, and Fourier-transform infrared (FTIR) spectrometer to validate all material and product performance parameters. The company’s overall product defect rate is maintained below 0.2%, 75% lower than the LSR manufacturing industry average of 0.8%.
Xiangchu has implemented a digital MES (Manufacturing Execution System) that tracks every production batch from raw material intake to shipment, with unique QR codes assigned to each batch for full traceability. Clients can access batch-specific documentation including raw material certificates of analysis (COA), production process records, inspection reports, and regulatory compliance certificates upon request.
For regulated industries, Xiangchu provides all required documentation to support client product approval processes:
The company also offers custom packaging solutions including ESD (electrostatic discharge) protective packaging for electronic components, sterile packaging for medical parts, and moisture-proof packaging for long-distance shipment.
Xiangchu’s R&D team, consisting of 32 material scientists and process engineers, focuses on developing application-specific LSR solutions that address unmet industry needs, with 23 utility patents and 4 invention patents related to LSR material formulation and processing technology. The company works closely with clients from initial product design stages to optimize material selection, mold design, and production processes for performance, cost-effectiveness, and manufacturability.
Xiangchu’s medical LSR product line is manufactured in a Class 10,000 clean room workshop, with all production processes compliant with GMP requirements. The company’s medical components are used in surgical instruments, diagnostic equipment, drug delivery systems, and implantable devices:
The company has supported 42 medical device clients in obtaining FDA 510(k) and CE marking approval for their products, with zero quality-related approval delays reported over the past 5 years.
As the global automotive industry shifts toward electric vehicles (EVs), Xiangchu has developed a full line of LSR components for EV and traditional automotive applications, with all products compliant with IATF 16949 and RoHS requirements:
Xiangchu is currently a tier 2 supplier for 8 major automotive OEMs including BYD and Volkswagen, with a 0 PPM (parts per million) defect rate for automotive components delivered over the past 3 years.
Xiangchu’s consumer product line combines high performance with aesthetic appeal, catering to consumer electronics, baby product, and kitchenware brands:
