Investment Casting Process - Lost Wax Casting
Investment casting, also known as lost wax casting, converts molten metal in a single operation to precision engineered components with minimum wastage of material, energy and subsequent machining.
The process is extremely versatile and cost effective, and is excellent for complex components where fine detail and dimensional accuracy are required. It also reduces or totally eliminates the need for costly machining operations and, as several parts can be made as one casting, the time and cost involved for subsequent assembly is removed. This provides numerous advantages and flexibility for engineers and designers and can be a great alternative to other manufacturing processes due to the complex shapes and little surface finishing that is required to the finished parts and the varied metals and alloys that are able to be used.
Investment casting - using the lost wax casting technique - is one of the oldest casting methods known dating back over 5000 years and examples of its uses in producing jewellery and statues can be traced back to use with natural waxes.
