About Fuding Xinlong Mechanical Components Co., Ltd - Piston & Piston Rings Supplier in China

Fuding Xinlong Mechanical Components Co., Ltd operates from China and currently lists five active products in its online catalogue. The supplier’s focus is on piston‑related components used in automotive braking and valve systems, which are grouped under the top category “Piston & Piston Rings”.

The catalogue includes a clutch piston series, a brake cylinder piston series, an antilock brake system (ABS) valve core series, a plunger type piston series, and a proportional valve assembly. Each item is positioned within the automotive brake and hydraulic control segment, a sub‑category of machinery components that typically fall under HS Chapter 84 for machine parts.

Product Range and Specialties of Fuding Xinlong Mechanical Components Co., Ltd

The clutch piston series comprises forged steel or aluminum alloy pistons designed for dry‑clutch applications, with typical bore diameters ranging from 20 mm to 60 mm and operating pressures up to 150 bar. Brake cylinder pistons are usually machined from cast iron or high‑strength steel, featuring surface hardening (HRC 45‑55) and pressure ratings of 200 bar or higher for passenger‑vehicle brake calipers. ABS valve cores are precision‑cast components that control hydraulic pressure modulation; common specifications include a flow coefficient (Cv) between 0.5 and 2.0 and material grades such as AISI 4140 or 17‑4PH stainless steel. Plunger type pistons are used in hydraulic actuators and are often supplied in stainless‑steel grades (e.g., AISI 304) with stroke lengths from 10 mm to 120 mm. The proportional valve assembly integrates a piston, valve seat, and control circuitry, typically rated for flow control in the 0‑100 % range and built to ISO 26262 functional‑safety levels when used in safety‑critical systems.

Trade and Export Information - Fuding Xinlong Mechanical Components Co., Ltd

China is a major exporter of automotive brake components, and shipments of pistons and valve parts from Chinese manufacturers are routinely classified under HS codes 8708.99 (parts of brake systems) and 8483.90 (valves and fittings). Primary import markets include the European Union, the United States, Japan, and emerging automotive hubs in Southeast Asia such as Thailand and Vietnam. Buyers usually request compliance with ISO 9001 quality‑management systems and, for safety‑critical brake parts, IATF 16949 or CE marking. Standard export packaging consists of wooden crates or metal pallets with anti‑corrosion coating, and logistics often use FOB Shanghai or CIF Rotterdam depending on buyer preference.

Sourcing from Fuding Xinlong Mechanical Components Co., Ltd - Buyer Guidance

When sourcing pistons or valve assemblies from this supplier, buyers should request material test certificates (e.g., chemical composition, tensile strength) and functional test reports that verify pressure‑holding capacity and dimensional tolerances. Samples of critical dimensions (bore, stroke, valve seat diameter) should be inspected against the relevant ISO or SAE specifications before full‑scale orders. It is advisable to confirm the supplier’s ability to provide ISO 9001 or IATF 16949 audit reports, and to verify that packaging meets ISO 14001 environmental handling if required for the destination market.

What material grades are available for the clutch piston series?

Typical grades include forged carbon‑steel (e.g., 20CrMnTi) and high‑strength aluminum alloy (e.g., 7075‑T6), each supplied with hardness values and heat‑treatment certificates.

Which standards apply to the brake cylinder pistons?

Brake cylinder pistons are commonly manufactured to meet SAE J231 and ISO 26262 requirements, with surface hardness between HRC 45‑55 and pressure testing up to 200 bar.

What documentation should be requested for the ABS valve core series?

Buyers should ask for a material certificate, a flow‑coefficient (Cv) test report, and any CE or IATF 16949 conformity evidence.

Is a minimum order quantity (MOQ) required for the proportional valve assembly?

Suppliers often set an MOQ of one full production batch, which can range from 500 units to 2 000 units depending on the valve size and customization level.

What are the typical lead times for the plunger type piston series?

Standard lead times are 30‑45 days from order confirmation, assuming no special material or dimensional requests.

How are the products packaged for international shipment?

Items are usually packed in wooden crates with anti‑corrosion coating, labeled with HS codes 8708.99 or 8483.90, and secured with shrink‑wrap or metal straps for sea freight.

Which Incoterms are most commonly used for these components?

FOB Shanghai and CIF Rotterdam are the most frequently applied Incoterms for automotive brake and valve parts exported from China.

What certifications are typically required by buyers of these brake components?

Buyers commonly require ISO 9001 quality‑management certification, IATF 16949 for automotive‑specific quality, and CE marking for safety‑critical parts destined for the EU market.
