An ODM wax setting machine is a production system developed or adapted to place loose diamonds or other stones into wax models before casting. The right solution depends on your stone dimensions, wax patterns, production workflow, and required placement method—not simply on the machine’s name. Before requesting a quotation, define what you need the machine to do, which materials and models it must handle, and how you will evaluate a sample. At SONGNA, we recommend using these details to guide an early technical discussion rather than assuming one standard configuration will suit every workshop.
This guide is for jewelry manufacturers, diamond-setting workshops, casting businesses, and sourcing teams considering an ODM wax setting machine. It is especially relevant if you handle loose diamonds and need to place stones in wax models before casting. Buyers exploring a new production method can also use it to prepare questions for equipment suppliers. If your process sets stones directly into finished metal jewelry, confirm that the equipment under discussion is designed for that different operation.
In a wax-setting workflow, stones are positioned in a wax model before the model enters a casting process. A machine may support or automate parts of this placement work, depending on its design and the production method. “ODM” means that the buyer and supplier discuss a product design or configuration for a defined requirement; it does not, by itself, guarantee that every requested feature is available. Ask the supplier to identify which parts are standard, which can be customized, and which would require separate development.
Suitable applications may include jewelry models with repeated stone placements or production tasks where a consistent process is important. Actual suitability depends on the geometry of each wax model, the stone type and size, access to each placement point, and how the workpiece is held. A design with a clear, repeatable layout may present a different challenge from a model with curved surfaces or tightly spaced stones. Provide representative workpieces so the supplier can assess your actual application rather than relying on a broad product description.
Start by documenting the loose diamonds or other stones you intend to use. Include their dimensions in millimeters, shape, any relevant sorting tolerances, and the expected range of variation; do not assume a machine supports a size range until the supplier confirms it. Share wax model drawings or samples, including details that affect access and positioning. Also explain how models are currently supported, loaded, and removed, because a fixture or handling change may be part of the project.
For an initial evaluation protocol—not as a machine performance claim—consider preparing 10 representative wax patterns across 3 stone-size groups. Ask the supplier to record placement results and cycle time in seconds per stone under the agreed test conditions. The test should include examples of your actual model geometry, not only easy-to-reach positions. Define in advance how you will judge acceptable placement, damage, rework, and repeatability.
Confirm the electrical supply, installation space, operating environment, and any compressed-air or other utility requirements with the supplier before purchase. Request the machine’s rated power in watts and its required input voltage for the offered configuration rather than relying on a generic specification. Clarify how the equipment will fit into your existing steps, including preparation, inspection, casting, and any manual finishing. If operators need training or new work instructions, include those needs in the project scope.

Customization can concern workholding, machine layout, controls, stone or model handling, and the way the equipment fits into a production line. Which options are practical depends on the supplier’s engineering capability and the confirmed application. Prepare a requirements list that distinguishes essential functions from preferences, then ask the supplier to respond item by item. This makes it easier to identify technical gaps before price discussions become the focus.
Compare suppliers using the same application information and test expectations. A quotation should make clear what is included, what remains optional, and which assumptions affect the price. Ask whether drawings, samples, or tooling are needed for evaluation, and who owns or retains any project-specific design materials. For an ODM project, written agreement on revisions, approval stages, and responsibilities helps reduce avoidable scope misunderstandings.
Pricing for an ODM wax setting machine can vary with the agreed configuration, engineering work, tooling, control requirements, and support package. A meaningful comparison therefore requires a defined scope; a low initial quotation may not cover the same items as a more detailed proposal. Ask suppliers to separate machine cost from customization, fixtures, shipping, installation, and optional services where applicable. Treat any estimate as provisional until the technical requirements and commercial terms are confirmed.
Minimum order quantity and lead time also depend on the supplier’s production and project arrangements. Ask whether the proposal is for a single customized machine, a repeat order, or a broader production program, and request the timing assumptions in writing. Confirm when the lead-time clock begins, such as after drawing approval, deposit, or receipt of samples, if those conditions apply. Avoid relying on an informal delivery estimate before the design and acceptance process are clear.
At SONGNA, we use the buyer’s application details to structure an initial ODM discussion and identify information needed for a technical assessment. Share product drawings or representative samples, stone size ranges, target workflow, and facility requirements so the conversation can focus on compatibility. We can then clarify which customization requests need further review and what information is needed to prepare a suitable proposal. Final capabilities, configuration, schedule, and commercial terms should always be confirmed for the specific project.
An ODM wax setting machine may be a fit when its confirmed configuration supports your loose diamonds, wax models, workholding method, and production workflow. The most reliable way to assess that fit is to provide representative samples, define measurable acceptance criteria, and review the supplier’s scope in writing. Begin by preparing your model drawings, stone dimensions in millimeters, workflow description, and facility requirements. Contact SONGNA with these details to discuss application compatibility, possible customization, and the information needed for a project-specific quotation.
