Sanmei manufactures replacement gun bodies, electrodes, nozzles, barrels and machined fittings for thermal spray systems. Each part is produced as an equivalent component from a part number, drawing, photograph or physical sample, so an existing installation can be supplied from a second source without changing its process.
Sanmei is an independent manufacturer and supplier of replacement parts. We are not authorised, appointed or endorsed by any equipment manufacturer. See the disclaimer below.
Replacement purchasing is usually a risk decision before it is a price decision. These are the four pressures we are asked about most often.
Electrodes, nozzles and barrels are wear items replaced on a repeating cycle. When one supplier defines both the price and the replacement interval, the annual parts budget is difficult to influence from the shop floor.
Imported consumables can carry long quoted lead times. A delivery that slips past a planned maintenance window shifts the problem into production scheduling, where the options are limited.
With a single qualified source, any change in capacity, pricing structure, minimum order quantity or distribution terms is passed directly to the buyer, usually without an alternative already on file.
When a torch is out of service, the cost is measured in delayed work and idle labour rather than in the price of the component. A verified second source exists so one missing part cannot stop a coating line.
The categories below are produced against the geometry and material of the component being replaced. Suitability is confirmed item by item, not by catalogue category.
Housings and torch bodies carrying the main bore, taper and thread geometry.
Electrodes for plasma torches, including bonded tungsten-copper assemblies.
Plasma, HVOF and cold spray nozzles defined by bore profile and outlet diameter.
Barrel and extension sections for combustion and high-velocity systems.
Chambers and chamber liners machined for pressure and mixing geometry.
Powder and gas injectors, including fine-bore and multi-port variants.
High-wear seals, O-rings, insulators and insulating sleeves sized to the original seat.
Adapters, unions, gas fittings and comparable small parts produced to drawing.
A component outside this list can still be reviewed: send the reference and the geometry will be assessed against our machining capability before anything is quoted.
Any one of the four references below is enough to start. Where documentation is incomplete, a sample part is the most reliable input.
The number on the component, the packing list or the maintenance record, together with the gun model or system it is fitted to.
A 2D drawing with dimensions and tolerances, or a 3D model. This is the strongest reference for critical features.
Clear images of the part from several angles, with any stamped marking legible, and one image showing it in place on the torch.
A worn or new part sent for measurement. Return arrangements for the sample are agreed before it is shipped.
A part number identifies a component; it does not define it. Before a replacement is released, the reference is measured and the machining programme is built from those numbers.
The sequence below is the one we recommend for a first order. It is arranged so a replacement part is judged on your equipment and under your parameters before any serial supply begins.
A part number, drawing, photograph or sample, plus the gun model or system the component is fitted to.
The reference is identified and measured, and we confirm whether it corresponds to a standard item or must be produced from the reference itself.
You receive the confirmed specification for the item, the unit price and the available quantity breaks, on the geometry that was verified.
A small batch is produced first, from the same material and the same machining programme that serial supply would use.
The trial parts run on your equipment, so coating quality, deposition behaviour and part life can be observed under your operating parameters.
On approval, repeat batches follow the qualified drawing and its inspection plan, scheduled against your consumption.
Trial quantities and the acceptance criteria are agreed in writing before the batch is produced, so both sides are judging the same result. Trial data stays with the part record for later batches.
Two measured values are specified on replacement wear parts. Both are verified during production, not sampled at the end of it.
The values above apply to the features defined as critical on the confirmed drawing of the part being replaced. Where a customer drawing specifies a different tolerance, that drawing governs.
Material grade and hardness are checked against the drawing before machining starts.
Critical dimensions are measured during machining, so any drift is corrected inside the batch rather than discovered after it.
Inspection results are recorded against the production batch and can be provided with the shipment on request.
Send whichever reference you already hold. A short description of the equipment the part is fitted to helps us confirm the match in fewer exchanges.
Send the part number and the gun model or system it belongs to. If the number corresponds to an item we already produce, the specification and price are issued against it.
A 2D drawing with dimensions and tolerances, or a 3D model, is the most complete input. Add the quantity, the process it serves and the material if it is specified, and we will confirm the critical features before quoting.
Photographs of the worn part, a marking or a nameplate are enough to begin an identification. For a firm match on the dimensions, a sample part is measured and returned or replaced as agreed.
References are treated as customer information. Send them through the request-a-quote form or the contact page; both accept an attachment with the enquiry.
Changzhou Sanmei Industrial Equipment Co.,Ltd is an independent manufacturer and supplier of replacement parts for thermal spray equipment. Sanmei is not an authorised distributor, agent, licensee, affiliate or partner of any equipment manufacturer, and no authorisation, approval, sponsorship or partnership of any kind is claimed or implied.
All product names, brand names, model designations and part numbers referenced by customers remain the property of their respective owners. They are used only to identify the component that a replacement part is intended to fit, and their use does not indicate any connection with, or endorsement by, the owner of those names.
Replacement parts supplied by Sanmei are equivalent components manufactured by Sanmei. They are not OEM-branded goods, are not manufactured by the original equipment manufacturer, and are not presented as original equipment parts.
Share whichever reference you hold. We will confirm the match, state the specification, and quote a first trial batch so the part can be judged on your equipment before volume supply.
