You can provide us your detail information. Such as the product outlook, function, colors.... we will quote you roughly cost and prototype sample charge. If it is workable, then our engineer will start drawing the 3D picture and making function board. The prototype will start making when you approval the 3D drawing and demo board function. After that, we will send the prototype to customer to do approval. The plastic mold will be starting making if customer confirms us the prototype. It will take 30-35 days.
Next step we will make pre-production sample to send to customer to do approval again. If everything is going well then we will tell customer how long mass production the item.
Normally, the production lead time is around 30 –45 days which depend on the order QTY and what kind of product does.
