In the manufacture of metal products of complex shapes, the method of investment casting is widely used. Currently, the market is represented by a fairly large range of model injection molding compounds. From the simplest (a mixture of paraffin and stearin) to multi-component with improved properties. The most common and quite budget-friendly are model compositions based on paraffin, ceresin and polyethylene wax. This composition allows for precise casting of complex shapes. The advantages of these formulations are described in detail in the patents: RF-2088370, RF-2447969, RF-2162386, RF-2080204, RF-2060854.In addition, polyethylene wax is used in the manufacture of separation lubricants to facilitate the removal of rods from the model rod tooling.
