# Central China Liquid Silicone Rubber Custom Processing
---
Central China Liquid Silicone Rubber (LSR) Custom Processing is a full-service manufacturing solution for brands, product developers, and industrial OEMs seeking high-precision, custom-molded silicone components from our Central China production base. Leveraging regional supply chain advantages, advanced injection molding infrastructure, and over 15 years of LSR formulation and processing expertise, we deliver fully customized silicone parts that meet strict international quality standards at competitive lead times and costs.
Our end-to-end service covers every stage of custom production: from initial material formulation consulting, prototype testing, mold design and fabrication, to full-volume mass production, post-processing, and final packaging. We support projects ranging from low-volume prototype runs (as small as 10 units) to high-volume mass production exceeding 10 million units annually, accommodating custom requirements for hardness, color, functionality, size tolerance, and surface finish. As a leading regional LSR processing specialist, we integrate raw material production and secondary processing in one facility, eliminating third-party markup and reducing supply chain risk for global and domestic clients.
Core value propositions of our service include strict adherence to customer design specifications, full material traceability, flexible order quantities, and compliance with global regulatory requirements for diverse end-use industries.

All LSR materials used in our custom processing are sourced from our own formulation facility or certified global raw material suppliers, with full traceability from batch to finished part. Available material options include:
Finished custom components maintain consistent physical performance aligned with client specifications:
Our production process is optimized for consistent LSR molding:

Located in the Central China industrial belt, we benefit from low logistics and labor costs compared to coastal manufacturing bases, with easy access to major domestic ports and national logistics networks for both domestic distribution and global export. We maintain 30+ tons of raw material inventory for common LSR formulations, enabling a 5-day lead time for prototype projects and 15 to 25-day lead time for mass production, 20% faster than industry average.
Unlike third-party processing brokers, we handle all stages of production in-house: from mold design and fabrication, material compounding, molding, to post-processing and quality inspection. This eliminates miscommunication between multiple vendors, reduces production costs by 10% to 15%, and ensures full control over quality at every stage. Our in-house mold workshop can produce custom LSR molds in 7 to 10 days, with lower mold maintenance costs for long-term production.
We support custom material formulation to meet unique functional requirements, including self-lubricating LSR, conductive LSR, dielectric LSR, flame-retardant LSR (UL94 V-0 grade), and adhesion-promoted LSR for overmolding onto plastics, metals, and glass. We specialize in complex process requirements including two-shot multi-color LSR molding, insert molding, and micro-molding for parts as small as 0.1g.
All materials and processes comply with major international standards, including FDA 21 CFR 177.2600 for food contact, REACH SVHC, RoHS 2.0, and ISO 13485 for medical devices. We provide full batch traceability for every order, with material test reports (CoA) and quality inspection reports available upon request.

Our Central China LSR custom processing service supports a wide range of industries and use cases:
---
Choose the appropriate LSR hardness based on your application requirements:
We accommodate custom component sizes from 0.1g micro parts up to 1200mm x 800mm large-format silicone parts. For projects requiring overmolding onto inserts, we support insert sizes up to 300mm x 300mm with precise alignment tolerance. Minimum order quantity (MOQ) is 10 units for prototype runs and 500 units for mass production, with no upper limit on order volume.
Select the appropriate material grade based on end use:
---
We operate our production facility under a strict ISO 9001:2015 quality management system, with medical-grade production compliant with ISO 13485:2016. Every production batch undergoes multi-stage quality inspection, including:
All materials are tested for compliance with RoHS 2.0, REACH SVHC, and relevant regional regulatory standards, with certification available for every order. In the rare case of non-conforming parts, we offer re-production or full refund within 7 working days of issue confirmation. Our 24/7 technical support team provides rapid response to design changes and order adjustment requests, ensuring long-term stable supply for global clients.
