Sanmei manufactures thermal spray gun bodies, form-fit-function replacement consumables, and complete Plasma and HVOF equipment. This page sets out what we make in-house, how a replacement part is confirmed before it enters your production, and how one qualified item can grow into multi-model supply.
A replacement component earns its place only when it installs without modification, runs at the same parameters, and holds that behaviour across repeat batches. Confirming this comes before any order is released.
Components are produced to the reference geometry of the original part: mounting interfaces, threads, bore and taper, gas and powder passages. The objective is a direct swap in the existing torch or gun body, not an adaptation your operators have to work around.
Send a part number, technical drawing, clear photograph, or physical sample. We identify the reference, confirm what can be supplied against it, and state plainly where a dimension or material cannot be matched.
Once a part is qualified, its drawing revision, material specification, and inspection criteria are fixed. Repeat orders are produced against that record, so the component you approved is the component you receive next time.
Any one of these is enough to open a technical review. Sent together, they shorten the confirmation.
The service life of a plasma or HVOF component is decided by geometry and surface quality. We machine the parts that carry that load ourselves and measure them against the reference before they leave the shop.
Turning, milling, and boring of the body geometry, mounting interfaces, and threaded junctions that position the torch.
Copper and tungsten-copper components machined and finished for stable arc behaviour under continuous load.
Gas and powder passages machined to the drawing, with internal surfaces finished to resist powder adhesion.
HVOF combustion chambers and barrels manufactured and inspected as controlled parts of the delivered assembly.
We support the Plasma and HVOF platforms in common industrial use, together with the internal-bore and extended variants required for cylinder walls, pipe interiors, and deep cavities.
Gun body and consumable components, including electrodes, nozzles, and gas-distribution parts.
Torch components covering electrodes, cathodes, nozzles, and insulating parts.
Torch components, electrodes, nozzles, and gas-distribution parts for SG-100 plasma duty.
Gun body and consumable components for repeat plasma production.
Barrel, nozzle, and gun body components, together with the fittings that complete the assembly.
Compact and extended configurations for internal diameter spraying, deep cavities, and restricted access work.
Coverage for a specific model and variant is confirmed item by item against your part number, drawing, or sample before it is quoted.
Rather than publishing an unmanageable catalogue, we keep depth in the consumables and components that decide torch behaviour, coating repeatability, and unplanned downtime.
Copper and tungsten-copper electrodes produced for stable arc starting and predictable wear in continuous plasma duty.
Gas passages machined to the reference profile to keep flow, velocity, and spray pattern within the established parameters.
Feed and injection components finished for consistent powder delivery without buildup at the port.
HVOF pressure-bearing components manufactured and inspected as part of the delivered assembly.
High-wear insulating and sealing parts that protect alignment, gas tightness, and electrical isolation.
Non-catalogue machined items, including adapters and interfaces for older or modified torch setups.
If a component is not part of the maintained range, it can still be reviewed as a development item against your drawing or sample.
A part that does not exist in anyone's catalogue can still be manufactured. Send the drawing or the worn original and we will work from the geometry it carries.
Drawing, sample, photograph, or part number is logged with the gun model it belongs to.
Dimensions, material, and surface requirements are checked against the reference, and any open point is raised before manufacturing.
A first article is machined in-house, measured, and recorded against the agreed drawing revision.
The prototype is run under your operating parameters so fit, ignition, and coating behaviour can be judged on the machine.
Once accepted, the drawing, material specification, and inspection criteria are frozen for series production.
Every production batch passes the same sequence, and nothing is released until the inspection step for that batch is closed and recorded.
Raw material arrives against a specification and is checked before it enters machining.
Critical geometry is measured during machining rather than discovered at the end of the batch.
Finished parts are checked against the drawing, including the internal surfaces that govern flow and buildup.
The batch record is closed and the goods are released for packing and dispatch.
Inspection records are kept per batch, so a qualification decision made last year still refers to the same criteria this year. See how quality is controlled.
Technical questions are answered by the people who review the drawings, and order quantities are set by what you actually consume rather than by a fixed minimum.
Compatibility, material, and geometry questions go to the technical team directly, so answers arrive with a drawing reference rather than a general reply.
Evaluation quantities for a first trial and scheduled repeat volumes for production use are both produced on the same equipment and criteria.
Single items and mixed requirements covering several gun models can be combined in one order and one shipment.
Qualified parts remain in the maintained range, which is what makes a second source useful over several years rather than one order.
Delivery schedules are quoted per order and confirmed against your required date and order quantity.
The same manufacturing base that produces replacement parts also builds complete coating systems, so gun, consumable, and equipment questions are handled in one place.
Core subsystems are manufactured in-house and combined with established instrumentation, so a system can be specified around the workpiece, the coating, and the throughput you need.
Manufacturing CapabilityBuyers rarely start with a full programme. They start with a single component that has to prove itself, and the relationship grows from there on evidence rather than on promises.
A single consumable is matched, produced, and run on your machine until it is accepted.
Neighbouring parts on that gun model are added using the same verified reference data.
The full set for that torch, from electrodes and nozzles to seals and fittings, is supplied as one package.
Coverage extends to the other platforms in your shop, so purchasing keeps one technical record for several models.
Where it makes sense, the same relationship covers complete Plasma or HVOF systems and their spare parts.
Each step reuses the qualified drawing revision and material specification from the step before it, which is what keeps a growing scope from becoming a growing risk.
Tell us the gun model and what the part has to do. We will confirm compatibility, quote it against your quantity, and hold the technical record for every repeat order.
