Uniform and reasonable strength check method is very necessary and important for coasted sand casting technique

Professional China bucket tooth pin production supplier said the strength can be regard as the important mechanical parameter for entirety coated sand casting technique, so to find an uniform and reasonable strength method is very important and necessary to coated sand casting technique.

For example, professional China bucket tooth pin production supplier would adopts the core shoot machine to manufacturing the test samples first, but remember adjust the core shoot pressure is equal or smaller than 0.5MPa; due to the actual temperature for core box is continue hold with two hundred and ten degree, so to ensure the correct testing result, professional China bucket tooth pin production supplier said the suitable sample testing time must controlled about ninety seconds.

Professional China bucket tooth pin production supplier said the best testing thickness for testing sample must be half of standard testing sample, in the other words, the testing thickness must be eleven point two millimeters, and to maintain the correct strength testing result, professional China bucket tooth pin production supplier said the best strength intensity meter must be lever type intensity meter.
