Innovative manufacturing and ecologically sound practises can often go hand in hand to create both a better environment and more efficient production processes. This has proved particularly true with the investment casting technology developed by DRYTECH LIMITED. In the past, the use of alcohol based fluids, as suspension for the solid matter from which investment moulding castings are produced, was commonplace. The fast evaporation of the alcohol allowed wax patterns to be re-coated more quickly than would be possible with water as a suspension fluid. The adverse effect of the process on the environment has lead to legislation in many countries, which requires that the use of alcohol based fluids be discontinued. By developing an environmentally friendly solution to the problem, with effective and practical automated drying and air conditioning systems, together with robot operation, Drytech has provided the manufacturing benefits of much improved, consistent quality, faster production cycles and reduced storage space requirements.
