Double Head Jewelry Wax Setting Machine: A Buyer’s Guide to Applications and Specifications
A double head jewelry wax setting machine is designed to support stone placement in jewelry wax models using a two-head configuration. For buyers working with loose diamonds, the key question is not simply whether a machine has two heads, but whether its tooling, controls, and working method suit the stones, wax patterns, and production workflow you use. Before purchasing, confirm what “double head” means on the proposed model, which stone and wax parameters it supports, and what acceptance checks the supplier can demonstrate.

This guide explains common applications, specifications to compare, and questions to ask when evaluating a machine. It also distinguishes machine capabilities from requirements that depend on your own production process. Use the checklist to prepare a clear inquiry to SONGNA or another potential supplier.
Who This Guide Is For
This guide is intended for jewelry manufacturers, wax-model workshops, diamond-set jewelry producers, and sourcing teams evaluating equipment for stone placement before casting. It is especially relevant if your business handles loose diamonds and needs to determine whether wax setting belongs in its production flow. Buyers replacing existing equipment can also use the specifications below to identify gaps before requesting a quotation.
The right configuration depends on the product, stone range, wax pattern, operator skill, and downstream casting requirements. A machine description alone cannot establish compatibility with every stone or design. Ask suppliers to assess representative samples or review detailed process information where a fit is uncertain.
Basic Concept and Typical Applications
What “Double Head” Should Mean in a Quotation
The term “double head” identifies a machine with two heads, but it does not by itself explain how those heads operate. Depending on the design, they may support separate work positions, different tools, or another paired arrangement. Ask the supplier to describe the head layout, whether both heads can be used at the same time, and what adjustments are independent.
Wax setting generally refers to placing stones into prepared wax patterns before a later production stage such as casting. This differs from setting a finished stone directly into a metal jewelry piece. Confirm that the machine is intended for your specific wax-setting process rather than assuming that any jewelry stone-setting equipment will work with wax.
Where It May Fit in a Loose-Diamond Workflow
Potential applications include jewelry designs that call for stones to be positioned in wax models before casting, subject to the machine’s method and the production process. The suitability of a loose diamond depends on factors such as its dimensions, shape, setting geometry, and handling requirements. Your team should also check how the wax model and stone will be protected during placement and subsequent handling.
Wax setting is not automatically appropriate for every design or stone. Some products may require a different manufacturing route, and the final setting method may depend on casting results and finishing requirements. Share a representative design and stone specification with the supplier before treating wax setting as a confirmed fit.
Specifications to Review Before Buying
Machine Configuration and Process Controls
Begin with the machine’s operating principle and the functions assigned to each head. Request clear information about adjustment methods, workholding, operator controls, and any heating or temperature-control features. If the process uses a heated tool, ask for the operating range in °C and how the temperature is adjusted; do not assume that a particular temperature suits your wax or stones.
Ask for the input voltage in V, rated power in W, machine dimensions in mm, and any stated positioning or repeatability specification in mm. These figures are product-specific and should be confirmed in the supplier’s quotation or technical sheet. As an illustration of a buyer-defined requirement—not a SONGNA machine specification—you might list a target placement tolerance of ±0.1 mm if your design and quality process require it.

Compatibility With Stones, Wax, and Designs
Provide the supplier with the stone shapes and size range you handle, along with the wax type, pattern dimensions, and representative setting geometry. Ask whether the supplied tools or tips are suitable for those inputs, whether alternatives are available, and which items are included in the quoted package. Compatibility should be assessed against your actual materials rather than inferred from a general product category.
For loose diamonds, handling and orientation matter as much as nominal size. Clarify how stones are positioned, what adjustments an operator makes, and whether the equipment supports the designs you plan to produce. If you work with multiple stone sizes or pattern types, ask how changeovers are handled and whether extra tooling is needed.
Application-Matching Framework
- Define the product: List the jewelry styles, stone shapes, and wax patterns that represent your regular production.
- Describe the process: Explain how wax models are prepared, how stones are introduced, and what happens after placement.
- Set measurable requirements: Specify the stone dimensions in mm, required placement tolerance in mm if known, and operating conditions relevant to your workshop.
- Confirm the two-head design: Ask for a diagram or demonstration that shows each head, its function, and any shared or independent controls.
- Review a sample workflow: Where practical, ask the supplier how your representative design and materials can be evaluated before ordering.
This process helps separate must-have capabilities from optional features. It also gives suppliers a consistent basis for recommending a configuration. If you cannot yet define a tolerance or process limit, say so and ask what information is needed to determine one; avoid accepting an unsupported performance figure as a guarantee.
Pricing, MOQ, and Lead Time
Machine pricing can depend on configuration, included tooling, control options, and customization. Request an itemized quotation that identifies the machine, accessories, packaging, and any optional components separately. Confirm the currency, payment terms, quotation validity, and whether installation or operator guidance is included.
Ask whether the supplier has a minimum order quantity (MOQ) for the machine, spare parts, or customized tooling. Lead time should be confirmed in writing and clarified as starting from which event, such as deposit receipt or final specification approval. If your purchase is time-sensitive, also ask how shipping arrangements and any required documentation affect the delivery plan.
Supplier Evaluation Checklist
- Does the supplier explain the double-head arrangement and provide a clear specification sheet?
- Are voltage, power, dimensions, operating conditions, and any accuracy claims stated with units?
- Has the supplier reviewed your wax type, stone range, and representative designs?
- Does the quotation list included tools, optional accessories, spare parts, and exclusions?
- Can the supplier describe inspection, commissioning, operator instructions, and after-sales support?
- Are MOQ, lead time, payment terms, packaging, and shipping responsibilities clear in writing?
Ask for evidence that relates to your purchase, such as a machine demonstration, documented specifications, or an agreed sample evaluation. A general claim of suitability is less useful than a written explanation tied to your materials and process. Keep the approved configuration and acceptance criteria with the purchase documents.
Common Buying Mistakes
One frequent mistake is treating “double head” as a complete performance specification. The number of heads does not establish output, precision, or suitability for a particular stone. Another is comparing quotations without checking whether tooling, training, or essential accessories are included.
Buyers may also overlook the difference between wax placement and final metal setting. Confirm the machine’s intended role in your workflow and how the wax model proceeds through later stages. Finally, avoid relying on a sample specification or illustrative value as a guaranteed machine capability unless the supplier confirms it for the quoted configuration.
Key Takeaways and Next Steps
A double head jewelry wax setting machine may fit a production process that places loose stones into wax models, but the correct choice depends on the machine’s actual head arrangement, compatible materials, tooling, and your design requirements. Compare specifications in consistent units, confirm whether the quoted configuration meets your process needs, and seek a sample review or demonstration when compatibility is uncertain. Do not assume that two heads alone guarantee higher output or that a general-purpose machine suits every diamond and wax pattern.
To move forward, prepare a short inquiry with your stone shapes and dimensions in mm, wax type, representative pattern, required electrical supply in V, and any known placement tolerance in mm. Ask SONGNA to clarify the double-head configuration, provide the relevant technical details in writing, and itemize price, MOQ, lead time, included tooling, and support. This gives your team a practical basis for deciding whether the machine matches your application before placing an order.
