AdTech is a manufacturer specializing in the development of new materials and the production of Casting Thimble and Tundish Nozzle for hot top casting. The company has been developing and producing hot top casting products since 2012: Casting Thimble.
Transition Plate, Distribution Launder, Foundry Pouring Cups, Graphite Ring, Ceramic Fiber Distributing Launder
The products are used in metal solution casting equipment, especially in combination with the wagstaff air-slip casting table for precision casting. When casting, the aluminum liquid of the distribution plate is connected to the mold mold for molding, and the market is recognized by more than 98% of the existing customers. .
AdTech’s Casting Thimble is made of high-silicon melt 140 and Al-Si. It has strong corrosion resistance, high geometric precision, smooth casting surface, long service life, low maintenance cost and no pollution to molten metal. It is the hottest top casting. Good choice, meet the technical needs of aluminum alloy precision casting products such as aviation, transportation and electronic products that produce high added value and high technical performance requirements.
Features & application:
AdTech’s thimble is made of two kinds of materials: high fused silica materials and Al-Si materials. It is the best choice for hot-top casting with high corrosion resistance, high geometry precision, smooth surface, long service life, low maintenance cost and non-pollution to molten aluminum, especially suitable for Wagstaff equipment. The molten aluminium is poured into the mold crystallizer from distribution plate during casting. It can meet the technical requirements of precision casting of .aluminium alloy.

The advantages of Casting Thimble
- Featured with none-stick smooth surface, high geometric precision, low maintenance cost.
- No delamination or peeling, effectively reduce the pollution of aluminum liquid.
- Good thermal shock resistance and heat insulation, excellent cost performance.
Hot Top Aluminum Billet Casting Instructions for Use
Select the hot-top casting equipment platform mounting accessories for the corresponding specifications.
Install Distribution Launder, Casting Thimble, Transition Plate, Ceramic Fiber Distributing Launder, Graphite Ring on the upper side of the platform, casing and adapter plate. The graphite ring is installed on the inside of the crystallizer to ensure clean, no damage, no gap, side and The bottom is preferably sealed with ceramic fiber paper or ceramic fiber blanket to help keep the insulation.
After the whole hot-top casting platform is installed, evenly preheat the installed equipment platform to 260-350 °C. It can be electrically or gas-baked. There should be no open flame contact with the product lining, otherwise the crack damage will occur. The user undertakes to remove the adsorbed crystal water and use it safely and efficiently.
