Water glass investment casting

Find a local office. The fragile wax patterns must withstand forces encountered during the mold making. Silica sol method dewaxes into the flash fire, and silica sol zircon sand makes the ceramic mold.

Step 2: Make an Investment

This was a project I did water glass investment casting a group for my Materials Science class. Since I had access to a laboratory full of materials testing equipment, I’ll give you some extra castimg data. But if you happen to have access to casting invesfment at home, you should be able to produce similar effects! Necessary materials: -glass -something to smash glass -materials to make an investment mold wax, investment plaster, flasks, a vacuum sealer -something big enough to hold glass over investment at around degrees C Please read through the steps first- this materials list is probably not comprehensive. I’m not an expert- none of us had tried working with glass before this project.

Investment casting (water glas process)

Water glass casting is one of the most common investment casting processes in China, but is seldom in other countries. So what is water glass casting? Water glass casting, one kind of lost wax investment casting process, uses water glass as the binder for the shell. The origin of water glass casting is in Russia. Process of water glass casting is what we described in investment casting process , with this method, it is suitable for steel castings , especially for carbon steel and alloy steel castings. It allows to produce steel castings ranging from 0. For each casting to be made, melted wax is injected into a mold to produce a wax pattern of the casting.

Step 1: Make Wax Pieces

Water glass and silica sol investment casting are the two primary investment casting methods nowadays. Imvestment creates the greatest pressure differential to fill the molds. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required. The main differences are the surface roughness and cost of casting.
