No. Ramson is not a separate registered company—it is the brand name under which Jiu Sheng Chen International Trading Co., Limited, the manufacturing arm of JSC (Jiu Sheng Chen International Trading Co., Limited, Hong Kong, Reg. No. 77029037), presents its factory-direct engineering and OEM/ODM capability to overseas buyers. Huizhou Ramson Technology owns the 25,000-square-meter factory, the production lines, and the patent portfolio, and carries responsibility for design, sampling, and quality control. Every contract, quotation, invoice, and after-sales claim tied to an inquiry made through this page is still issued by JSC, under the same founder and controller, Gigi_Xie — there is no third-party subcontracting and no separate legal entity behind the Lamason brand.

Yes — that is what this page is for. Qualified overseas buyers with contract-manufacturing or private-label requirements can use this page to review production capability, mechanism test data, and certification scope before requesting a quote, then route the inquiry to the same JSC team that handles standard trade orders. This path generally suits buyers placing recurring bulk orders who want to evaluate factory engineering directly. Smaller or first-time orders are equally welcome here; they follow the identical quotation, documentation, and after-sales process described on JSC's main site, since both paths end at the same contracting entity.

Our 2876U mechanism series passed independent SGS fatigue testing at a 360 lb distributed load across 25,000 full extension-and-retraction cycles, with no structural damage, abnormal noise, or functional loss recorded at the end of the test. Translated into daily use, 25,000 cycles works out to roughly 13-plus years at typical household reclining frequency, and considerably less under continuous hotel or public-seating traffic—which is why contract-grade projects add reinforced base frames on top of the same tested mechanism rather than relying on the mechanism rating alone. Full SGS test reports are available on request for a buyer's own compliance file.

Yes. Powered mechanisms are certified via Shenzhen CTL Testing Technology to CE-LVD under EN IEC 60335-2-32:2021 (read together with EN 60335-1) and CE-EMC under EN IEC 55014-1 and 55014-2. Units are also RoHS 2.0 compliant across all restricted substances, including the four regulated phthalates, and screened under REACH SVHC against the current 247-substance candidate list with no substances detected above threshold. For North American orders, electronics carry FCC SDoC under Part 15 Subpart B. Certificate copies and test reports are issued alongside shipment documentation as standard, not held back for a separate request after delivery.

The standard minimum order quantity is one 40HQ container. Sampling typically takes 7 to 14 days from a confirmed technical brief, and mass production runs 30 to 45 days depending on configuration, fabric sourcing, and order volume. Buyers combining several product lines or custom mechanism variants in one container should expect timing toward the upper end of that range, since mixed-configuration orders require additional QC checkpoints between product types. A production schedule with committed dates is issued at the quotation stage, before deposit, so lead time is confirmed upfront rather than estimated after the order is already placed.

Verified manufacturing defects reported within the agreed claim window are covered under a defined compensation process rather than handled case by case. This typically includes replacement parts or components for the affected units, drawn from the same spare-mechanism and actuator supply used for after-sales support. Claims are assessed against the bill of materials and certification scope confirmed at the quotation stage, so a defect is checked against the original order specification rather than a general warranty statement. Buyers should raise a claim with photos and batch reference numbers early, since claim windows run from the shipment date, not the date of use.
