Method of integrating wear plates into a spray formed rapid tooling includes the steps of making a model of a desired tooling and constructing a ceramic pattern as the inverse of the model. The method also includes the steps of locating at least one wear plate on the ceramic pattern and thermally spraying a metal […]

Method for rapid tooling manufacturing comprising the steps of first building an SFF pattern made of plastic to be used to make a first die half. Then there is the step of spraying metal onto the pattern to form a first metal substrate. Next, there is the step of separating the substrate from the SFF […]

Heat pump system adapted to use a non-azeotropic refrigerant mixture preferably containing a high boiling temperature refrigerant as a primary component thereof is given an improved heat transfer efficiency and its pressure loss is minimized by arranging a refrigerant extracting means for removing the refrigerant stagnating in the system in an unfavorable state, in a […]
