Xinhai Rubber
Silicone seals, vibration-damping pads, miscellaneous molded parts, tubing and profiles are listed in the supplier’s six-page catalogue. The Dongguan company was registered in July 2026; rubber manufacturing is in scope. Material grades, tolerances, sample terms and export responsibility still need written confirmation.
Six product groups, engineering details next.
Sealing Rings & Gaskets
O-rings, sealing washers and oil seals appear in the supplier catalogue. Material formulation, dimensions, tolerance and compression-set test results are not supplied.
Vibration Pads & Buffers
Feet, buffers and silicone pads are pictured. Ask for load, deflection, hardness and ageing data; no damping rating is claimed here.
Custom Molded Parts
Drawing- or sample-based tooling is supplier-stated. Confirm tooling ownership, sample approval, cavity plan, flash limits and repeat-order controls.
Silicone Tubing
Straight, coiled, corrugated and reinforced-looking tube images appear. Grade, inner and outer diameter, wall tolerance and pressure limits remain unverified.
Profiles & Strips
Solid and hollow sealing-profile images are included. Request cross-section drawings, length tolerance, joint method and actual extrusion evidence.
Sheets & Cut Pads
Sheet, flange-gasket and cut-pad formats are pictured. Temperature, chemical resistance and food-contact suitability require grade-specific evidence.
What the registry confirms, and what stays open.
Manufacturing in Registered Scope
The register includes 橡胶制品制造；合成材料制造（不含危险化学品）；模具制造；电子元器件制造. This establishes business scope, not a factory audit.
July 2026 Company
Active limited company established 10 July 2026. RMB 1 million registered capital; paid-in amount and insured headcount were not disclosed in the source returned.
Equipment in Catalogue
The supplier labels an open mill, automatic feeder and 200T / 250T molding presses. These are catalogue statements, not independently audited equipment or capacity.
Export Entity to Confirm
No goods/technology import-export clause is present in the returned scope. Obtain written exporter, invoice issuer, payment entity and customs arrangement; absence of the clause alone is not a legal conclusion on export eligibility.
Registered Address
广东省东莞市塘厦镇河畔路8号11号楼401室. The catalogue describes the fourth floor of building 11 at the same street location; ask for a current walkthrough and factory-use evidence.
Product Evidence Open
No technical datasheet, grade-specific test report, ISO certificate, customer case permission or order terms were supplied. Small embedded catalogue pictures are not substituted for high-resolution originals.
What was checked — and what the check found.
Registry data and risk results were read on 13 October 2026 via the enterprise-data API: all four returned risk categories have zero items. This is a dated database result, not a guarantee of no risk. Catalogue statements remain supplier-stated. No independent site audit, material validation or food-contact conformity assessment has been performed.
A newly registered maker, with open checks shown.
Xinhai Rubber is the listing name for Dongguan Xinhai Rubber Products Co., Ltd. (东莞市鑫海橡胶制品有限公司), a Dongguan limited company registered on 10 July 2026. Its returned registered scope includes rubber products, synthetic materials excluding hazardous chemicals, molds and electronic components manufacturing, related sales and domestic trade agency.
The six-page supplier catalogue groups seals, vibration pads, custom molded parts, tubing, strips and sheets. It labels molding presses and other equipment, but provides no measurable capacity or engineering specification. General claims of quality, chemical resistance or high pressure are not converted into verified claims here.
Before a first order, agree drawings and grade, sample acceptance and inspection criteria, tooling rights, quantity and lead time, and the exporter and payment entity. High-resolution product originals, process evidence and grade-specific test records are requested.
