Manufacturing Advantage
Structural designers develop the pop-up mechanism first — layer count, fold behavior, opening angle — before graphic designers apply artwork to the cut lines. CMYK offset printing with gloss varnish finishing is used on art paper. The sound chip, LED components, and blow-out sensor are assembled and tested in-house. Each finished card is checked to verify the music triggers on opening, the lights activate correctly, and the blow-out response functions before packing. Quality control spans every production batch, and production records are maintained so repeat orders stay consistent with earlier deliveries. The blow-out interaction mechanism is covered by patented technology. Packaging support covers the standard OPP bag with envelope, with retail display box options on request. ISO9001, BSCI, and FSC certifications are held. MOQ is 500 pieces per design. Sampling takes 7-10 working days through the stages of graphic design, structural modeling, blank sample verification, coloring, and digital sample production.

FAQ
1.What details do you need for a price estimate?
Dimensions, quantity, color or artwork changes, music and lighting preferences, packaging, and whether you are adapting an existing design or starting new. A reference image helps us return a faster quote.
2.Can the blow-out response be programmed with a different sound or light pattern?
Yes. The standard setup uses a birthday melody on open and a cheering track after the candle is blown out. Both tracks, the LED behavior, and the trigger sensitivity can all be adjusted. You can supply your own audio, and we will load it onto the module.
3.How do I confirm the electronic functions work correctly before committing to bulk production?
After the blank structural sample, we provide a fully assembled sample with the sound module, LED lights, and blow-out sensor installed. This lets you test every function — open for music, blow to trigger the response, close to stop — under real conditions. Both stages together take 7-10 working days from artwork and audio sign-off.
4.Can I mix orders across different card categories in one shipment?
Each design must reach its own 500-piece MOQ. After that, different card types can be packed into a single shipment to simplify freight and documentation.
5.What is the production timeline after sample confirmation?
We schedule production once the sample is approved and the deposit lands. Total lead time depends on order volume and how long the electronic modules take to source. Placing the order ahead of your selling season allows enough room for sampling, component preparation, production, and transit.
