Machine selection
Machine Selection FAQ
These questions help buyers avoid choosing a machine only by model name or price.
Which resin doming machine should I choose first?
Start with product layout, production volume and positioning risk. A semi-auto doming machine is better for samples and small batches. A 3-axis automatic machine fits regular sheets and repeat orders. A CCD vision-guided machine is used when mixed layouts, holes, cutouts or placement variation create higher positioning risk.
When is a semi-auto doming machine enough?
Semi-auto operation is enough when you make samples, small batches, changing product types or simple decals where flexibility matters more than daily output. It is not the best choice for stable high-volume production because output and consistency depend more on operator skill.
When should I choose a 3-axis automatic doming machine?
Choose a 3-axis automatic doming machine when your decals, labels or nameplates are arranged in regular sheets and repeat orders use stable layouts. Saved programs and fixtures help improve efficiency, but the sheet layout and product placement still need to be repeatable.
Can a 3-axis machine handle complex shapes?
The issue is not only the product outline. A 3-axis machine can dispense around many shapes if the sheet layout is fixed and repeatable. If parts are freely placed, mixed on one sheet, have holes or show printing-position variation, CCD vision alignment is usually safer.
When do I need a CCD vision-guided doming machine?
CCD vision is useful when positioning errors are expensive: mixed layouts, holes, cutouts, free placement, curved or premium products, or printed sheets that are not perfectly repeatable. It should solve a real alignment risk, not simply be chosen because it is the highest-level machine.
Is the most expensive doming machine always the best choice?
No. A higher-level machine is only better when it matches the production problem. If your products are simple and regularly arranged, a 3-axis machine may be more practical than CCD. If you mostly do samples, semi-auto may be more flexible and easier to justify.
Resin and quality
Resin and Doming Quality FAQ
Short answers for resin choice and common doming quality risks. For deeper resin comparison, use the resin guide.
Should I use epoxy resin or polyurethane resin?
Epoxy resin is often used for rigid indoor products that need a hard, glossy dome. Polyurethane resin is usually a better starting point for outdoor, flexible, curved or UV-exposed products. Final selection should consider substrate, dome height, use environment and sample testing.
Can one doming resin work for every product?
No. Resin choice changes with material, surface finish, flexibility, edge design, outdoor exposure and target dome feel. The same resin that works on a rigid indoor label may fail on a flexible or outdoor product. Sample testing is the safest way to confirm.
How can I reduce air bubbles in domed labels or decals?
Bubbles may come from resin mixing, trapped air, viscosity, substrate condition, hose leakage or dispensing settings. Vacuum degassing, stable A/B mixing, clean substrates and the correct mixer/nozzle setup can help, but the cause should be checked as a complete process.
Why is dome height inconsistent?
Uneven dome height can come from unstable resin volume, uneven product surface, fixture flatness, nozzle distance, viscosity changes or sheet movement. Before changing machine model, confirm resin behavior, product layout, substrate flatness and dispensing parameters together.
Can resin domed products be used outdoors?
Yes, but outdoor use should be tested carefully. UV exposure, temperature, moisture and product flexibility can affect the dome. Polyurethane resin is often the better starting point for outdoor or flexible products, while final performance should be confirmed with aging or sample checks.
Sample testing
Sample Testing Before Purchase
Sample testing reduces selection risk when product material, layout, outdoor use or dome quality is uncertain.
Can I send samples before buying a doming machine?
Yes. Sample testing helps confirm resin flow, adhesion, dome height, edge control, bubble risk and machine matching before purchase. It is especially useful for outdoor products, flexible substrates, premium labels, mixed layouts or customers buying resin doming equipment for the first time.
What should I provide for sample testing?
Send product photos, material, size, sheet layout, target dome height, expected monthly volume and use environment. If possible, send physical samples or printed sheets. Drawings and videos also help Robota understand product placement and positioning risk faster.
What will Robota check during sample testing?
Robota checks whether the product surface accepts resin, whether epoxy or polyurethane is more suitable, whether bubbles or edge overflow appear, and whether the product layout needs semi-auto, 3-axis automatic or CCD vision-guided dispensing.
Will I receive sample photos or video feedback?
Robota can provide sample photos, test feedback or video references when available. The goal is to help you understand the likely machine and resin setup before quotation, not to replace final production validation in your own factory environment.
Accessories
Accessories and Consumables FAQ
These questions focus on spare stock, replacement parts and process stability, not unnecessary add-on purchases.
Are basic accessories included with a new doming machine?
Yes. A new Robota doming machine normally includes the basic accessories and startup consumables needed for the selected configuration. Extra accessories are mainly for after-sales replacement, spare stock, production stability upgrades or changed resin/product requirements.
Which consumables should I keep in stock?
Most customers keep static mixers, nozzles, seals, common fittings and selected hose parts. The exact list depends on machine type, resin type, cleaning frequency and production volume. For repeat orders, small consumables can prevent unnecessary downtime.
Can accessories solve bubbles or unstable dispensing?
Accessories can help, but they are not the only cause. Bubbles or unstable dispensing may also come from resin viscosity, mixing ratio, trapped air, substrate condition, operating method or machine settings. Check resin, process and accessories together.
How do I order the correct replacement part?
Send the machine model, old part photo, resin type and a short description of the production problem. This avoids ordering a similar-looking mixer, nozzle, hose or fitting that does not match the current machine and resin setup.
Quotation and support
Quotation and Support FAQ
Use these answers to prepare a practical inquiry without turning the FAQ page into a heavy contact form.
What information is needed for a quotation?
Please provide product type, material, size, sheet layout, expected volume, use environment, target dome height, resin preference and clear product photos. This helps Robota recommend a machine, resin setup and optional accessories based on the real production requirement.
How long does it take to receive a recommendation?
It depends on how complete the product information is and whether sample testing is needed. For simple products, Robota can usually suggest a direction after reviewing photos and requirements. For complex or outdoor products, sample testing may be recommended first.
How should I think about machine lead time?
Lead time depends on machine configuration, order schedule, customization and testing requirements. FAQ pages can only provide a general expectation. Robota should confirm the final delivery schedule after reviewing the required setup and current production plan.
Can Robota support installation and training?
Robota can provide operation guidance, setup suggestions and production support based on the selected machine and application. The required support method depends on machine type, customer experience, factory condition and whether the setup includes automation or special resin requirements.
Can I become a Robota distributor or agent?
Distributor cooperation can be discussed after understanding your market, customer base, technical support ability and sales plan. This is a separate business conversation and should not replace machine selection or sample testing for your own production project.
