Inside Xiangchu Rubber: Company Background, Professional Depth and the Churub Brand

Most supplier pages say "professional". This one explains what professionalism looks like in silicone manufacturing, piece by piece — company structure, equipment decisions, quality system and the registered brand behind it all.

Who we are

Xiangchu (Hubei) Rubber Co., Ltd was established in Ezhou, Hubei, with a registered capital of CNY 1,000,000, as a limited liability company under Chinese company law. We operate as a general VAT taxpayer with independent import and export rights — meaning we handle our own export declarations, documentation and tax rebates, and our customers deal with the factory directly rather than a trading layer. The company is fully verifiable through its Unified Social Credit Code (91420704MAKACHA75E) in any Chinese business registry.

Professionalism you can inspect: equipment and cleanroom

Specialization shows up in capital decisions. Our core fleet — 85T, 120T and 160T precision vertical LSR injection machines — was selected for medical, baby-care and electronics programs, not commodity volume. Molding runs inside a class-100,000 cleanroom, because liquid silicone touched by uncured hands is a contamination event no QC step can undo. Mold making is in-house: our CNC toolroom designs and maintains the tooling that guarantees 500,000-shot mold life, which is why our pass rate holds at 99.5% across more than 2,000 delivered product models for 500+ customers.

Professionalism you can read: documentation and process

Depth is also visible on paper. We specify compounds by data — volatile matter, compression set, Tg — not by adjectives. We validate before production: peel tests, thermal cycling, migration testing, third-party biocompatibility where applications demand it. And every shipment carries its documentation: material certifications, DoC, dimensional reports. Ask any supplier for a sample documentation package; how completely they respond tells you more than any factory tour.

The Churub brand and our trademarks

Churub is the global brand of Xiangchu Rubber, supported by registered trademarks in China covering our product and service classes — not a trading name adopted last year, but the brand identity our product lines have operated and exported under. For buyers, the practical meaning is accountability: the trademark owner, the factory and the legal entity that signs your contract are the same company. When you specify Churub on a drawing or a purchase order, one entity owns the result end to end — and its registration records are public, checkable, and stable.
