Vacuum forming

I have tried vacuum forming, and I have practiced now. Today, I report still in progress.

To start vacuum forming, must to prepare tool of vacuum forming. This tool sell at the shop of plastic model, but it's expensive. So, I make by my hand in economy. :D I got little wood box and crevice tool of vacuum-cleaner in 100 yen shop.  (this store is like an one dollar shop or 99 cent shop in USA) And I bought a punching sheet and sponge tape in other store. The cost of materials is under 1000 yen (about $10). :) 

Next, I assemble a vacuum forming tool.
1. Cut short crevice tool, make a hole in the box for crevice tool. insert a crevice tool in the box, and fix by glue.
2. Put a punching sheet on the box by glue, and moreover gummed tape. And put sponge tape. 
Box size is 11cm X 11cm. The inside diameter is 9cm X 9cm. But this inside area is a little wide to miniature. So, I made frame that made in paper and sponge tape to make little area.

Prepare two plywoods (11cm X 11cm), make hole 6cm X 6cm each, sandwich a sheet of plastic 7cm X 7cm (0.3mm thick) between plywoods, and fasten with a clip. This photo is plastic sheet after heat and vacuum. I have tried and practiced some various mold. I practiced in the mold of kouglof in this photo.
I guess that this hole is still a little wide. I will make new frame that inside area 5cm X 5cm. 

Well... I have made a lot of trash now. XO I understand:
simple form(circle or square plate etc.)could vacuum forming well.
detail and very little or thin line etc. could not or difficult. 

But I guess I could do it. I need more time to succeed....

Especially, it's amazedness that plastic sheet melt, and it become like a melted cheese, and change the form when put on a mold and vacuum. It's interesting to do. :D

Recently, some Japanese miniature creators have done vacuum forming or simple heat press. So, I decided to ride on the boom too. :D I learned this technique and knowledge in some site of plastic model and miniature creator. I thank them they have opened generously the knowledge in their site. :-)

What a great idea! I did some vacuum forming in college with a large machine. I never thought it would be possible to make your own for miniature! Please keep sharing your progress on your homemade tool. It's amazing!
