# Liquid Silicone Rubber OEM Manufacturing Service
Our Liquid Silicone Rubber (LSR) OEM manufacturing service provides end-to-end custom production solutions for brands, product designers, and medical device manufacturers seeking high-precision LSR components. With over 15 years of specialized experience in LSR injection molding and compression molding, we support full-cycle development from initial prototyping to mass production, accommodating custom formulations, geometries, and performance requirements that meet industry-specific regulatory standards.
Unlike standard off-the-shelf silicone products, our OEM service delivers fully customized LSR parts tailored to your exact application requirements. We work with clients across all stages of product development: whether you have a fully defined CAD model ready for production, or only a conceptual design that requires material selection and design for manufacturing (DFM) optimization, our in-house engineering team provides technical support to bring your product to market efficiently. Our core selling points include flexible production volumes (from 10-unit prototyping runs to 10,000,000+ unit mass production), full material traceability, compliance with global industry certifications, and competitive pricing that scales with your order size.
We support a full range of LSR material formulations to match your performance requirements:
All raw materials are sourced from global leading silicone producers including Dow Corning, Shin-Etsu, and Wacker, ensuring consistent material quality and batch-to-batch performance.
Our manufactured LSR components are tested to meet the following performance benchmarks:
We specialize in two core LSR manufacturing processes, optimized for different part geometries and production volumes:
Secondary processing capabilities include deflashing, precision cutting, CNC post-machining, plasma treatment, laser marking, and adhesive bonding for overmolded LSR-plastic/metal assemblies.
Unlike third-party trading companies that outsource production, our in-house engineering team provides end-to-end support from DFM analysis to mold design and mass production. We identify potential design issues such as poor venting, uneven curing, or ejection problems before mold fabrication, reducing development time and avoiding costly reworks. We also offer free prototyping services for qualified projects, allowing you to test form, fit, and function before committing to full mass production.
All raw material batches are tracked with full documentation, including material safety data sheets (MSDS), certificate of analysis (CoA), and lot traceability codes. We maintain compliance with the strictest global industry standards, including FDA food contact approval, ISO 13485 medical device quality management, REACH SVHC compliance, and RoHS 2 environmental requirements. We can provide full validation documentation for regulatory submission, supporting your product approval process in North America, Europe, and Asia-Pacific markets.
We accommodate projects of any scale, from 10-unit functional prototypes for startup product testing to 10 million+ annual mass production for established consumer brands. Our 8,000-square-meter production facility houses 12 dedicated LIM production lines, with capacity to scale up production within 2 weeks of order confirmation to meet sudden demand spikes. We also offer vendor-managed inventory (VMI) services for long-term OEM partners, reducing your supply chain management costs and ensuring consistent delivery.
Our optimized LSR manufacturing processes reduce material waste and cycle times, allowing us to deliver high-quality custom LSR parts at 10-15% lower cost than industry averages for comparable quality. Standard lead times are 7-10 days for prototyping, 2-3 weeks for mold fabrication, and 2-4 weeks for mass production, depending on order size and complexity.
Our Liquid Silicone Rubber OEM manufacturing service serves a wide range of industries with custom components:
Choose LSR hardness based on your application's functional requirements:
We support custom part geometries from 2mm micro components (such as micro valves for medical devices) to 2000mm large-format LSR sheets and gaskets. Provide your CAD file in STEP, IGES, or STL format, and our engineering team will confirm manufacturability within 2 working days. For clients without CAD files, we also provide reverse engineering services to convert physical samples into production-ready designs.
Select material grade based on your industry regulatory requirements:
We implement a 6-stage quality control process for all OEM projects, starting from incoming raw material inspection through final finished product testing. Every batch of raw material is tested for hardness, viscosity, and curing performance before entering production. In-process quality checks include dimensional inspection every 2 hours, visual inspection for surface defects, and curing uniformity testing. Final finished product testing includes compression set verification, tensile strength testing, and 100% visual inspection for critical medical and food contact components.
Our manufacturing facility is certified to ISO 9001:2015 and ISO 13485:2016 quality management systems, and all our standard LSR formulations are compliant with RoHS 2, REACH SVHC, and relevant regional industry regulations. We provide full quality documentation with every order, including batch test reports, material certificates, and regulatory compliance statements, supporting your internal quality audits and external regulatory submissions. For long-term OEM partners, we conduct annual performance reviews and process optimization to continuously improve product quality and reduce production costs.
