A custom wax setting machine nozzle should match the machine interface, wax delivery method, and the stone-setting task; a part that looks similar may not fit or perform as intended. Before ordering a replacement, compare the original nozzle or drawing against its connection dimensions, outlet geometry, material, and operating conditions. If you do not have a drawing, provide clear measurements and photographs so a supplier can review the fit before production. At SONGNA, we recommend confirming the machine model and application first, then agreeing on a dimensioned specification rather than relying on a visual match alone.
This guide is for jewelry manufacturers, loose diamond setters, wax-setting machine operators, maintenance teams, and procurement professionals sourcing a replacement or custom nozzle. It is also useful when an original part is worn, unavailable, or difficult to identify by part number. The aim is to help you prepare a clear inquiry and evaluate whether a proposed nozzle is suitable for your machine and process. Final compatibility should be confirmed against the machine and the nozzle’s actual dimensions.
A wax setting machine nozzle is the component that delivers or directs wax through a defined outlet toward the work area. Its geometry influences where the wax is deposited and how the material exits, while the machine and process determine the operating conditions. The nozzle is not a standalone performance upgrade: its fit and function depend on the machine’s mounting arrangement, feed system, wax, and intended setting operation. For loose-diamond work, the relevant requirement is controlled placement that suits the specific workpiece and production method.
Nozzles may differ in outlet shape, tip length, body profile, and how they attach to the machine. A straight outlet may suit a different access angle from an angled or extended tip, but the right choice depends on the machine layout and the target area. Connection details matter just as much as the tip: thread type, seating face, insertion depth, and any sealing features should be identified where applicable. Do not assume that two nozzles are interchangeable because they share a similar outside appearance.
Material selection should reflect the machine interface, wax compatibility, operating temperature, cleaning routine, and expected handling. Buyers may encounter metal or other material options, but suitability cannot be determined from a material name alone; the grade, finish, and design also matter. Ask the supplier to state the proposed material and finish in writing, and check whether they align with the original component or machine maker’s guidance. If the nozzle contacts heated wax or is exposed to repeated cleaning, include those conditions in your specification.
Start with the machine, not the catalog image. Record the manufacturer, model, nozzle part number if available, and the way the existing nozzle mounts. Next, describe the work being performed, including the required access angle and the location where wax needs to be delivered. If the nozzle is being replaced because of a process problem, explain what is happening rather than prescribing a new shape before the cause is understood.
For illustration only, an RFQ might show a 0.8 mm outlet, a 12 mm tip length, and a ±0.02 mm dimensional tolerance. These are sample values, not universal recommendations or SONGNA product specifications. Use dimensions from your actual machine, approved drawing, or supplier discussion rather than copying example figures. Also state which dimensions are critical and how they should be measured.

Check that the proposed nozzle matches the machine connection, including any seating or sealing surfaces. If you have an original nozzle, compare it with the drawing and note wear or damage that might distort measurements. If the machine documentation specifies a part number or interface, share it with the supplier and request confirmation in writing. Where compatibility remains uncertain, pause before ordering a production quantity.
Separate essential dimensions from preferences. A mounting feature or outlet location may be necessary for fit, while a surface finish or external profile may be negotiable depending on the application. Identify the outlet geometry and access angle needed for your work, and explain the reason for any requested change. This helps the supplier evaluate whether a custom design is practical without assuming that a smaller or longer tip is automatically better.
Share the wax and operating conditions that could affect the nozzle, including the machine’s stated temperature and pressure range where relevant. Ask how the supplier will verify the dimensions you consider critical and what inspection information can be provided with the order. Agree on drawing revision, material description, finish, packaging, and acceptance criteria before production. For repeat orders, retain the approved drawing and revision so future quotations refer to the same specification.
The cost of a custom nozzle can depend on its material, geometry, required tolerances, tooling or setup needs, inspection requirements, and order quantity. Minimum order quantity and lead time are supplier- and design-dependent, so they should be confirmed for the specific drawing and quantity rather than assumed from a standard part listing. A prototype or small trial order may be worth discussing when fit is not yet proven, although availability and cost will depend on the supplier’s production process. Ask for separate details on sample charges, production pricing, shipping, and any repeat-order conditions.
To reduce avoidable quotation delays, send the full specification in one inquiry and flag any dimensions that cannot change. If you need a replacement urgently, state the required date and ask whether the supplier can meet it before placing the order. Do not treat an estimated lead time as confirmed until the supplier has reviewed the design and acknowledged the order details. Any substitution should be approved against the agreed drawing and application requirements.
A reliable supplier conversation should clarify limitations as well as capabilities. If a machine model or measurement is uncertain, ask what additional information is needed before the supplier recommends a design. Clear written specifications help both sides avoid mismatched expectations, especially for custom or repeat orders. SONGNA can review your nozzle requirements and discuss a supply option based on the information you provide.
The right custom wax setting machine nozzle is the one that fits the machine interface and suits the wax-delivery task under your actual operating conditions. Begin with the machine model, original part or drawing, critical dimensions, outlet geometry, material expectations, and process details. Confirm tolerances, inspection expectations, MOQ, and lead time in writing before approving production. To request a review from SONGNA, prepare your machine information, photographs or drawing, required quantity, and target delivery schedule, then share them with your inquiry.
