RIDSDALE PEEL-BACK TESTER(FOR INVESTMENT TESTING OF RESIN COATED SHELL SAND)IGENERAL PRINCIPLESThis apparatus assesses the proportion of resin coated sand which peels away from themain body of the cured mould.The Peel-Back Tester consists of a hopper assembly mounted above a 250 x 250 x 30 mmhot plate, controllable to ± 10 °C, which is set in an elevated position and pivoted at thecentre to enable it to be rotated through 180°. A sample tray sits beneath the assembly tocollect the sand material which peels away.When the required temperature of the hot plate has been reached and stabilised anaccurately weighed quantity of resin coated sand is released from the hopper onto the hotplate. After a pre-determined time the hot plate is rotated through 180° in order to removethe uncured sand, which falls on to the sample tray beneath the assembly.Peel-Back quantity and curing speed factor are calculated from the proportion of sand fallingon to the sample tray, compared with the original weight.SPECIFICATIONS: Net Weight: 27.5 kgDimensions: 580 x 300 x 500 mmPower Supply: 220/230VII PURPOSE: To determine if cured sand separates and allows some to peelaway from the main body of the core or mould.(a)(b)Switch on Peel-Back Tester and adjust the Eurotherm to 205 °C. When theEurotherm reaches the pre-set temperature carry out the following test procedure :-Obtain a representative sample of the material to be tested of 300 grams, weighedaccurately. Make sure the heating plate is in the horizontal position.111
RIDSDALE PEEL-BACK TESTER (cont’d)IIPURPOSE: (cont’d)(c)(d)(e)Transfer the sample to the stainless steel funnel, placing a finger over the bottom ofthe funnel to restrict sand flow.Swing the funnel over to the centre of the hot plate and release the sand sample ontothe plate. Leave for 18 seconds and then invert the hot plate 180° and allow to setfor an additional one minute.After one minute weigh the material that has been collected in the tray on the bottomof the machine and subtract this weight from the sample weight used to give you apercentage peel.112
