Diesel plunger
The Diesel plunger from Hengli Auto Parts Plant is a precision-machined component used in fuel injection pumps for diesel engines, manufactured from high-carbon chromium steel with a hardened surface finish. Model numbers include 093400-6270 and 093400-6490, each designed for specific pump types such as Bosch VE, Zexel, or Denso systems. The component operates under extreme pressure, typically 1200 to 2200 bar, requiring tight dimensional tolerances and wear resistance.
The plunger is ground to a diameter tolerance of ±0.002 mm and surface hardened to 60 to 64 HRC using induction or nitriding processes. The surface finish is Ra ≤ 0.2 μm to minimize friction and prevent scoring during high-frequency reciprocation. These specifications align with industry standards for aftermarket fuel components. The material composition is typically 100Cr6 or equivalent, with trace elements controlled to ensure consistent hardness and fatigue life.
This plunger is used in agricultural tractors, marine diesel engines, and heavy-duty trucks where fuel system reliability is critical. Buyers include diesel engine rebuilders, OEM spare parts distributors, and fleet maintenance contractors. Packaging is in anti-corrosion paper with individual plastic sleeves, 50 pieces per carton. Minimum order quantities start at 100 pieces, and lead times are 20 to 30 days after payment confirmation. Trade terms are FOB Quanzhou.

Hengli Auto Parts Plant is a manufacturing facility located in Qingming Industry Economic Development Area, Quanzhou, Fujian Province, China. The supplier specializes in diesel fuel system components and lists model compatibility for common injection pump types. The profile does not disclose workforce size, annual production volume, or client names. Response metrics are unavailable, indicating limited buyer engagement on the platform.
The supplier claims compatibility with Bosch, Zexel, and Denso systems but provides no test reports, material certifications, or dimensional drawings. There is no mention of ISO certification, in-house metrology capability, or quality control procedures. Buyers should request physical samples and a dimensional inspection report before committing to bulk orders. The term 'imported' in the profile refers to sourcing of raw materials, not the supplier's export status.

Sourcing Diesel plunger from Hengli Auto Parts Plant - China Import Guide
Before ordering, confirm the exact model number compatibility with your injection pump. Request a sample to verify dimensions, surface finish, and fit with your existing barrel. Ask for a material certificate showing chemical composition and hardness test results. Avoid suppliers who cannot provide model-specific compatibility data, as incorrect plungers cause pump failure and engine damage.
Lead time is 20 to 30 days after payment. Incoterms are typically FOB Quanzhou. Payment is usually 30% advance, 70% against shipping documents. Confirm packaging: each plunger must be individually wrapped in anti-rust paper and packed in sealed cartons to prevent corrosion during transit. Request a container loading plan if shipping in bulk.
Upon receipt, inspect each plunger for scratches, discoloration, or deformation. Measure diameter and straightness with a micrometer and dial gauge. Test fit in a known-good barrel to confirm clearance. Retain a sample for third-party metallurgical analysis if used in critical applications. Ensure the supplier provides a batch traceability number on each carton for warranty claims.
