A dual head automatic wax setting machine is designed to automate stone placement or wax-setting operations with two working heads, helping jewelry manufacturers improve throughput and process consistency compared with a single-head setup. I recommend selecting this equipment based on your loose diamond range, wax model design, required setting accuracy, production volume, operator workflow, and after-sales support—not on head count alone. The right machine should be demonstrated with your own wax patterns and stones before purchase, because actual performance depends on machine configuration, tooling, material properties, and programming.
This guide explains what to evaluate, how to compare suppliers, and which questions to ask before placing an order. It is intended for jewelry factories, OEM manufacturers, wax model producers, and production teams working with loose diamonds or other small stones. My goal is to help you make a technically informed purchase while reducing compatibility, training, maintenance, and sourcing risks.
This guide is for manufacturers that are considering a dual head automatic wax setting machine for repeatable jewelry production. It is especially relevant when your factory produces multiple styles, works with CAD or wax models, or needs to coordinate stone-setting preparation with casting schedules. It can also help purchasing managers compare quotations from equipment suppliers.
The machine may be suitable for rings, pendants, earrings, bracelets, and other jewelry designs that use pre-defined stone positions. However, not every wax pattern is equally suitable for automation. Highly irregular designs, very small stones, deep cavities, fragile wax walls, or frequent manual adjustments may require additional testing or a different production method.
A dual head machine uses two setting heads or working units to perform programmed operations on a wax model or related jewelry production component. Depending on the configuration, the heads may work in sequence, process different positions, or support parallel handling of compatible tasks. The exact operating method must be confirmed with the manufacturer because “dual head” does not automatically mean that every operation is performed simultaneously.
Typical functions may include automatic positioning, stone feeding or placement, programmed movement, pressure control, and repeatable processing of defined patterns. The equipment may also include a control interface, fixture system, camera or alignment assistance, and adjustable tooling. I recommend asking for a complete functional description rather than relying only on a product name.
Manufacturers commonly consider this equipment for repeated production of jewelry wax models that contain loose diamonds or other calibrated stones. It can be useful when the same design is produced in batches and the production team wants to reduce repetitive manual positioning. It may also support production planning where two work areas or two heads can reduce handling between operations.
Before purchasing, provide the supplier with representative wax samples, stone sizes, stone shapes, design drawings, and expected daily output. A practical sample set can include at least 3 representative wax patterns: a simple design, a typical design, and the most difficult design in your current range. This gives the supplier a more realistic basis for evaluating compatibility.
Start by asking how the two heads operate and whether they share a motion system, work independently, or require separate programming. Confirm the available axes, positioning method, speed adjustment, pressure adjustment, and program storage capacity. For production planning, also ask whether the machine is intended for an 8-hour shift, continuous operation, or a specific duty cycle.
Control software is equally important. The interface should allow operators to create, save, revise, and recall programs without unnecessary complexity. Ask whether the supplier provides operating instructions, parameter backups, software updates, and training for new operators. If your factory uses CAD data, confirm whether files can be imported directly or whether programming requires manual teaching.
Do not accept a general accuracy statement without understanding how it is measured. Ask the supplier to specify the positioning accuracy in microns or another clear unit, the test method, the stone size range, and the wax conditions used during testing. Accuracy can change when wax hardness, surface condition, cavity design, stone tolerance, fixture stability, or tool wear changes.
Tooling and fixtures should match your product range. Confirm whether standard fixtures are included, whether custom fixtures are available, and how quickly worn tools can be replaced. For loose diamonds, discuss shape, size range, calibration tolerance, surface condition, and feeding requirements, because these factors can influence successful placement and reject rates.
Request the machine’s electrical requirements in watts or kilowatts, along with voltage, frequency, air supply, footprint, and operating temperature requirements. These details affect factory layout and installation cost. Also check whether the machine needs a stable workbench, extraction, special lighting, compressed air, or protection from wax dust and vibration.
A responsible supplier should provide an installation checklist and identify consumable parts. Ask which components require routine cleaning, lubrication, calibration, or replacement. This information helps your maintenance team estimate downtime and keep spare parts available before production begins.

Record your current and planned product range before requesting a quotation. Include stone type, stone dimensions, wax material, model size, batch quantity, daily output, changeover frequency, and operator experience. If the machine will serve several product families, identify the designs that require the most difficult positioning or the highest repeatability.
Compare the machine’s working envelope and tooling with your largest and smallest models. Check whether the two heads can process your preferred designs without collision, fixture interference, or repeated manual repositioning. Ask the supplier to explain which operations are genuinely automated and which steps still require manual preparation, inspection, or correction.
A sample test is one of the most valuable purchasing steps. Send or present representative wax patterns and loose diamonds, then request a written test record that identifies the program, material, stone range, number of samples, and observed defects. Do not judge performance from a demonstration using only an easy pattern.
During evaluation, inspect stone seating, position consistency, wax damage, changeover time, operator intervention, and repeatability across multiple pieces. If your internal quality system uses a specific tolerance, provide that requirement in advance. The supplier should distinguish between guaranteed specifications, test observations, and results that still depend on your materials or process conditions.
The lowest equipment price may not represent the lowest production cost. Compare the machine price with tooling, fixtures, packaging, installation, training, spare parts, shipping, import expenses, warranty coverage, and technical support. Ask for separate pricing so you can see which items are included and which are optional.
Lead time and minimum order quantity should also be clarified. A single machine may be sufficient for a pilot line, while a multi-machine project may require a phased delivery plan. Confirm the quotation validity period, payment terms, shipping responsibilities, commissioning arrangements, and acceptance criteria before signing.
| Evaluation Area | Questions to Ask | Evidence to Request |
|---|---|---|
| Application fit | Can the machine process our wax patterns and loose diamond range? | Sample test, process description, and limitations |
| Accuracy | How is positioning accuracy measured? | Defined unit, test conditions, and acceptance method |
| Productivity | How are the two heads used in our workflow? | Cycle-time estimate based on representative designs |
| Service | Who provides installation, training, and troubleshooting? | Service scope, response process, and spare-parts list |
Two heads can create a productivity advantage, but the benefit depends on how the heads are controlled and how your products are loaded. If operators must frequently reposition wax models or manually correct stone placement, the expected efficiency improvement may be limited. Ask the supplier to map the machine workflow to your actual production steps.
A machine that performs well on one wax type may not deliver the same result on another. Wax hardness, temperature, wall thickness, cavity geometry, and stone calibration can all affect the process. Test both typical and difficult designs, and document the conditions under which the result is acceptable.
Automatic equipment still requires correct programming, inspection, cleaning, and preventive maintenance. Lack of operator training can lead to incorrect parameters, unnecessary tool wear, and avoidable defects. Include training, manuals, program backup, and maintenance guidance in the purchase discussion.
At SONGNA, I approach a dual head automatic wax setting machine project by first understanding the customer’s products and production process. For loose diamond manufacturers and jewelry factories, this means reviewing stone characteristics, wax patterns, expected output, tooling requirements, and the level of automation required. We can then clarify which functions are standard, which require customization, and which should be verified through a sample test.
Our support discussion can cover machine configuration, application matching, technical documentation, packaging, installation guidance, operator training, spare parts, and after-sales communication. The exact scope should be confirmed in the quotation and technical agreement. This transparent approach helps buyers distinguish between confirmed specifications and application results that depend on their materials and operating conditions.
The best dual head automatic wax setting machine for your factory is the one that matches your wax patterns, loose diamond range, production volume, accuracy requirements, and operator workflow. I recommend starting with a documented application review, followed by a representative sample test and a detailed comparison of technical and commercial terms. This process provides stronger evidence than relying on a general catalogue description.
Your next step should be to prepare product drawings, wax samples, stone specifications, target output, electrical conditions, and preferred delivery schedule. Send these details to SONGNA for a configuration discussion and request a quotation that clearly separates machine functions, optional tooling, service scope, and delivery conditions. With the right technical information prepared in advance, you can evaluate whether a dual head solution is a practical fit for your jewelry manufacturing line.
