The lost wax casting technique is widely used to cast engineering components that demand extreme precision dimension, thin wall capabilities and high strength to weight ratio. Lost wax technique works on almost all metals and alloys and gives consistent output for all applications. The pattern or design is initially made from a fusible substance like wax, onto which plaster slurry is applied. After the plaster is set, the wax is melted away - lost wax! The wax leaves a cavity, in the shape of the pattern. The mold is preheated and the molten metal is poured into the cavity. The metal solidifies inside the mold and the cast part is regained after breaking away the mold. | |||||||||

A Technique Straight From The Pyramids Lost wax technique is also known by the term 'investment casting'. Egyptians developed a technique to make gold ornaments some 5000 years ago. Gold would have often used a form of investment casting right from the period of pyramids. The industry catered mainly to warplane components during the Second World War. After the war, decreased demand from defense applications helped the industry to focus on commercial applications including airframe components. The experience of catering to the demands of defense applications helped companies competently provide high-end parts to the civilian market. Almost all applications that require engineering parts requiring a combination of thin wall capabilities and highest levels of stress resistance rely on the lost wax technique. This includes high end air-frame components, engine and valve parts, marine parts and petrochemical and nuclear applications. It not only serves the high-end applications, the golf club head and lawn mower gear also use the same process. | |||||||||

Provides Strength and Stability Casting avoids the need of assembling or joining together various parts by welding or by fasteners. Single continuous structure gives predictable metallurgical properties through out the casting parts in all directions. This provides for easy testing for strength and stability of the parts (like jet plane door). It also reduces weight and saves on time and money, as few, if any, finishing touches are required. It can give precision parts that cannot be produced by other metal casting methods. Lost wax casting can produce engineering parts or components from alloys of aluminum, copper, titanium, stainless steel etc for whatever applications- be it dental implant or F1 engine, golf club head or rocket engine. |
