If you need a quote, the manufacturer must ask whether you have 3D drawings or ready or samples available? Without a 3d drawing or sample or prototype, the manufacturer won’t give quote to you, not because they have a bad attitude, but because even they give you a quote, it should not be precised, and they can not go to the next. It also shows you are not actually working seriously on it. So when you want a quote, the first step is to have the design or sample or prototype on hand.
It is difficult for manufacturer to give you price when you don’t have 3D drawings or ready or samples.
They need these reference data to give you price.Even they give you price is not credible if you don’t have 3D drawings or ready or samples.
