A double head wax setting robot is an automated machine designed to place stones into wax patterns using two setting heads. For jewelry manufacturers, the right choice depends less on the “double head” label and more on whether the machine can handle your stone types, wax designs, required output, and production workflow. Before requesting a quotation, prepare representative wax patterns and confirm the machine’s supported stone and pattern specifications with the supplier.

This guide explains what to evaluate, how to compare machine options, and which questions to ask before buying. It also outlines a practical sample-test process you can use with SONGNA or another potential supplier. Because configurations vary, treat machine capacity, accuracy, compatible materials, and delivery terms as items to verify rather than assume.
This guide is intended for jewelry manufacturers, production managers, sourcing teams, and workshop owners considering automation for stone placement in wax patterns. It is especially relevant to businesses producing repeated designs or evaluating a move from manual wax setting to a programmable process. If your products use loose diamonds or other loose stones, assess compatibility by stone dimensions, shape, and setting requirements rather than assuming every stone is suitable.
It can also help buyers compare quotations from suppliers. A machine with two heads is not automatically the best option for every workshop, since the right configuration depends on your product mix, staffing, available floor space, and required production volume. Use your own patterns and process requirements as the basis for comparison.
A double head wax setting robot places stones into prepared wax patterns through a controlled positioning and setting process. Depending on its design, the machine may use two heads to support different operations or improve how work is organized, but the exact arrangement and whether the heads operate simultaneously must be confirmed with the manufacturer. The machine’s control system, stone-feeding method, fixtures, and compatible pattern formats all affect how it fits into production.
Wax setting is commonly considered as part of a stone-in-place casting workflow, in which stones are positioned in a wax model before casting. Suitability depends on the stones, wax, pattern geometry, and downstream process. Buyers should discuss their full workflow with the supplier and confirm which stones and designs can be processed reliably.
Do not evaluate compatibility using stone type alone. Provide the supplier with information about stone shape and size range, the spacing and orientation of stones, wax pattern geometry, and any design features that may restrict access. Ask whether the machine requires particular fixtures, pattern preparation, or file formats, and request confirmation for the specific items you intend to produce.
Loose diamonds vary in shape and dimensions, so a machine’s suitability for one design does not prove suitability for every diamond-setting job. Include representative examples of your smallest and largest stones and your most complex patterns in the evaluation. If you also use other gemstone types, ask whether their physical characteristics require different settings, feeding arrangements, or process parameters.
Start with the work the machine must perform, not a supplier’s general description. Document your recurring designs, expected production volume, shift pattern, operator experience, and available floor space. Record your target output in pieces per hour or pieces per shift, then ask the supplier how that target should be assessed for your specific patterns.
Separate standard production from occasional or highly customized work. A machine may suit repeated patterns but require additional setup or handling for frequent design changes. Discuss changeover steps and operator tasks, including loading patterns, replenishing stones, checking output, and responding to interruptions.

| Evaluation area | What to confirm | Why it matters |
|---|---|---|
| Stone range | Supported shapes, dimensions, and feeding method | Determines whether your loose stones can be handled as required |
| Pattern compatibility | Wax pattern size, geometry, fixtures, and file requirements | Shows whether existing designs can be processed without changes |
| Two-head configuration | Head roles, operating sequence, and simultaneous or sequential operation | Clarifies the actual production benefit and workflow |
| Performance | Cycle time, repeatability, and output conditions | Allows comparison against your production target |
| Installation and support | Power, footprint, training, maintenance, and service arrangements | Helps assess readiness and ongoing operating needs |
Ask suppliers to define how they measure any stated accuracy or output figure, including the pattern, stone, and operating conditions used. Compare like with like: a cycle-time figure from a simple pattern may not represent your more complex work. Request the full specification and identify which items are standard, optional, or dependent on customization.
Prepare a practical acceptance test before making a decision. As a buyer-side example, select 10 representative wax patterns, including a typical design and more challenging examples, and ask the supplier to process them using your specified stones where possible. Repeat the test for 3 runs so you can observe whether results remain consistent; these are suggested evaluation quantities, not a claim about machine performance.
Record placement quality, visible damage, incomplete placements, setup steps, operator involvement, and cycle time in seconds or minutes. If your factory operates an 8-hour shift, use that shift length as a planning scenario to estimate how the machine might fit your schedule, but do not treat a short sample test as proof of full-shift output. Agree in advance on what constitutes an acceptable result and document any limitations observed.
The purchase price can depend on the selected configuration, tooling or fixtures, control options, installation requirements, and requested customization. Ask for an itemized quotation that distinguishes the machine from optional accessories, training, packaging, shipping, and any other applicable charges. Do not compare headline prices without checking that the offered configurations and service scope are equivalent.
Minimum order quantity and lead time are supplier-specific and may vary with configuration and order requirements. Request written confirmation of the production schedule, shipment terms, payment milestones, warranty coverage, and spare-parts arrangements. If you need a machine for a planned production start, confirm the timeline before placing the order and allow time for installation, operator training, and process validation.
Evaluate a supplier’s answers for clarity and evidence, not just breadth of claims. A useful supplier should be able to explain the proposed configuration, identify compatibility questions, and state what must be verified through testing. Ask for important commitments and exclusions in writing so that purchasing, production, and technical teams work from the same expectations.
When discussing a Double Head Wax Setting Robot with SONGNA, share your product requirements early so the proposed configuration can be assessed against your actual work. Useful inputs include representative wax patterns, stone specifications, target output, workflow details, and installation constraints. Ask SONGNA to clarify machine options, compatibility, quotation scope, lead time, and support arrangements for the configuration under consideration.
If your designs include loose diamonds, identify the shapes and size range you plan to process and explain any particular placement requirements. Where feasible, request a sample evaluation before confirming the order. This helps both sides focus on practical fit instead of relying on a general product label.
A double head wax setting robot may be a suitable investment when its confirmed capabilities match your stones, wax patterns, production targets, and operating environment. The number of heads alone does not establish output, accuracy, or compatibility, so verify those points against your own designs and documented supplier specifications. A structured test, clear quotation, and written support terms provide a stronger basis for purchase than an unqualified performance claim.
Your next step is to assemble representative patterns and stone specifications, define acceptable output and quality criteria, and request a configuration review and sample evaluation from SONGNA. Compare the results, total purchasing scope, and support commitments before making your final decision.
