How much does the studio cost to make these things?

30-inch and 40-inch crystals and pearls are less than 80 when cold-packed and more than 200 when hot-packed, and 8-inch pearls are not expensive even when hot-packed.

If these things are taken as a whole, they should be within 500, right?

Did you do it yourself by diy?

Hot mounting can't be considered unless you are the owner of Shanxi Black Coal Kiln, and you can burn money like that.

Cold mounting is very cheap. You can buy a 24-32 inch cold mounting machine around 300 or 400, and a roll of cold mounting film can mount most people's photos by yourself as long as it costs about 300.

Cold mounting is actually the process of pressing the cold mounting film onto the photo without heating. Nowadays, the cold mounting machine usually has a rubber roller. Put the photo on the flat plate of the machine and press it aside. Then one person holds the photo and film, and the other person shakes the handle to let the rubber roller drive the photo forward, and at the same time cover the film on the photo. You can also use a hard bottom plate for cold mounting, but I haven't done this. Anyone who sells machines can teach you how to do it. The cold mounting machine is very cheap.

And "thermal mounting" is to mount photos through the high temperature and high pressure of the thermal mounting machine. Hot mounting has the characteristics of no deformation, no discoloration and permanent preservation. Generally speaking, the cheapest thermal mounting machine is the kind of machine similar to heating and cold mounting. The size you bought is about 3000 ~ 7000, but vacuum hot stickers are better. That machine is more expensive and has better effect.

Cold-mounted/hot-mounted photo albums are made one by one by a cold-mounted/hot-mounted machine, and then bound by a certain process, with a front cover and a back cover (both for sale). However, whether it is cold mounted or hot mounted album, it needs some practice to be familiar with it. You'd better find a patient businessman and let him teach you more:)

You understand correctly, in fact, the main reason is that the initial investment is relatively large, and the price of consumables in the later period is still very cheap.
