Cylinder Liner Peugeot Manufacturer China: Sourcing Guide
A search for a cylinder liner Peugeot manufacturer China should not end with the cheapest bore size on a quotation sheet. The real buying question is narrower: can the supplier hold the geometry, metallurgy, surface finish, packing method, and traceability your Peugeot-fit programme needs after the first approved batch? Driventus manufactures wet and dry cylinder liners for passenger car and light commercial engine applications in Taizhou, Zhejiang, supporting aftermarket distributors, engine rebuilders, and private-label programmes. For Peugeot-fit references, buyers should confirm bore size, outside diameter, wall thickness, flange geometry where relevant, sealing-band details, honing condition, packaging, inspection records, and batch traceability before moving into repeat orders. RFQs should also state whether the liner is finished, semi-finished, or rough-machined; whether the buyer will complete final honing; and whether the order needs neutral cartons, private-label packaging, or bulk workshop packs. Driventus operates under IATF 16949:2016 and ISO 9001:2015 certified management systems and exports engine components to more than 60 countries. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only.
Decision framework: what must be locked before a quote means anything
A useful RFQ starts before price. Peugeot engine applications can have several service variants, and a liner has to match the block architecture, piston assembly, coolant sealing method, and machining allowance. A catalog liner, a semi-finished blank, and a finished liner controlled to your drawing are not equivalent offers.
Put these items in the RFQ:
- Engine family, displacement, fuel type, and production range where known
- Liner type: dry, wet, flanged, non-flanged, semi-finished, or finished
- Bore diameter, outside diameter, overall height, wall thickness, and flange dimensions where applicable
- Drawing tolerances for bore, OD, height, flange thickness, and seating face; where no drawing exists, state the inspection method you use
- Required surface finish, roughness range, honing angle, and whether plateau honing is required
- Material requirement, such as centrifugally cast grey iron, alloy cast iron, or a buyer-specified grade
- Hardness target or acceptable range, commonly defined in HB for cast iron liner programmes
- Piston and ring pairing if the liner is part of an overhaul kit
- OE or aftermarket cross-reference already used by your team, where relevant to your database
- Packaging format: neutral, distributor brand, single-piece carton, multi-piece carton, or bulk workshop pack
- Target annual volume, first order quantity, delivery schedule, and destination market
A 2D drawing with tolerances is better than a photo or part number alone. In most buying programmes, the controlled characteristics include finished bore diameter, OD, height, flange height, flange OD, chamfer position, and sealing-band width. Agree early which dimensions are checked 100% and which are sampled.
Semi-finished liners need special wording. State the machining stock, for example whether the bore and OD require 0.20-0.50 mm allowance for local finishing. Otherwise a low semi-finished price may be compared unfairly with a ready-to-install finished liner.
Physical samples still help. They show flange shape, chamfers, coolant-seal areas, anti-cavitation features, and finish condition, especially when the same reference has come from several aftermarket sources. If the sample has been used, mark it as used and identify worn areas so service damage is not turned into a new drawing feature.
Driventus can review drawings, samples, or existing aftermarket references through custom manufacturing. For standard engine component lines, buyers can also start from our catalog or the engine component range at /products/engine-components.html.
Spec deep-dive: where wet and dry liner production usually goes wrong
Cylinder liners work under thermal cycling, boundary lubrication, piston side load, and combustion pressure. The failure point in sourcing is often not the nominal dimension on the drawing. It is drift between batches.
Driventus uses controlled casting, heat treatment where specified, CNC machining, grinding where required, and plateau honing for liner production. A typical route runs from material selection and casting to rough turning, stress relief or heat treatment where specified, semi-finish machining, finish machining, honing, washing, rust prevention, final inspection, and export packing.
Wet liners bring their own risks. Flange seating, O-ring grooves, coolant sealing bands, and lower register dimensions need tight control because small errors can create coolant leakage, poor seating, or installation resistance. Dry liners shift the focus to interference fit, OD roundness, wall thickness, and bore stock. If the press fit is wrong, heat transfer and block retention suffer.
Typical controls include incoming raw-material verification, chemical composition checks, hardness testing, dimensional inspection, and final visual inspection for porosity, cracks, flange damage, burrs, rust, and handling marks. For export supply, production lots are traceable through internal batch numbers and inspection records.
| Control area | Procurement relevance | Typical verification | |
|---|---|---|---|
| Cast material | Wear resistance and thermal stability | Chemical composition report, hardness check, metallurgical review when specified | |
| Bore geometry | Piston-ring sealing and oil control | Bore gauge readings for size, roundness, taper, and cylindricity | |
| OD geometry | Press fit, heat transfer, and block retention | Micrometer or air-gauge checks across top, middle, and bottom positions | |
| Surface finish | Ring bedding and oil retention | Ra/Rz roughness measurement, plateau-honing check, cross-hatch visual inspection | |
| Flange or sealing area | Coolant and combustion sealing | Height, flatness, edge break, groove width, chamfer, and contact-face inspection | |
| Cleanliness | Reduced installation and early-wear risk | Washing, drying, bore wipe check, rust-prevention oil control | |
| Packing | Damage prevention in ocean and truck transport | Carton strength, VCI or oil protection, separator design, pallet labelling |
| Order type | Typical MOQ factor | Typical lead-time driver | Notes for buyers |
|---|---|---|---|
| Existing liner reference | Lower; often carton or pallet based | Stock, machining schedule, packaging | Suitable for distributor replenishment and trial orders |
| Semi-finished liner | Medium; usually batch based | Casting and rough machining | Allows local final machining by rebuilder; define machining allowance |
| Finished liner to drawing | Medium to high; depends on gauge setup | Gauge setup, honing, and first-article approval | Best for controlled aftermarket programmes |
| Private-label overhaul kit | Higher; driven by the slowest component | Multi-part coordination and carton design | Include pistons, rings, gaskets, or bearings if required |
| New custom liner | Project-based | Pattern, sampling, validation, correction loop | Use drawings or physical samples; allow sample review time |
