CUSTOMISED LOST WAX INVESTMENT CASTINGS

Rajan Techno Cast provides lost wax investment castings as per DIN, JiS, BS, and GOST standards. In addition to lost wax investment castings, Rajan Techno Cast is capable of casting any material composition that meets international standards.

The wax pattern for lost wax investment castings is grouped into clusters before undergoing a ceramic-coating process. This process is done in temperature- and humidity-controlled rooms to get the best dimensional accuracy and an excellent surface finish.

Once the ceramic-coating process has been completed, the de-waxing process, in which the wax is removed by putting the ceramic mould in the hot bath of wax, is performed.

WAX PATTERNS FROM DIES

Rajan Techno Cast's die manufacturing facility is well equipped with CAD / CANI facilities. The dies (patterns / tools) are manufactured using the latest CAD / CANI technology. The company also provides technical support to the injection and production of wax patterns from dies (patterns / tools). Rajan Techno Cast's quality team ensures all wax patterns from dies are 360° dimensionally checked.
