We manufacture REduced Pressure Test (RPT) Machine since 2001. The machine works on the Straube-Pfeiffer principal. Its purpose is to give a visual indication of the gas content in aluminum prior casting. The molten aluminum sample is kept inside the specially designed SS chamber with a glass dome and the required vacuum is attained in between 10 and 15 seconds. The molten sample is kept under vacuum for about 5 minutes, and residual gas inside the sample is indicated on the upper surface of the sample as well as very prominently indicated as blow holes when the sample is cut/machined. The size & the number of blowholes will depend on the gas content of the sample.
The sample if cooled under atmospheric pressure will not indicate the gas content as the one which has been cooled/solidified under vacuum and would have wrongly passed quality check prior casting.Some of the features of our machine are:
