Resin Mould for Ceramic Slip Rotary Moulding (CSRM) System

Abstract:

A type of porous resin was proposed to replace the existing plaster mould for Ceramic Slip Rotary Moulding (CSRM) system. The proposed resin is often used in high pressure casting of ceramic sanitary ware and table ware. The effect of resin mould in terms of mechanical strength (flexural properties), porosity percentage and percentage of water absorption as well as moulding process were recorded and compared with previous studies of plaster mould. Five (5) samples of porous resin were prepared according to ASTM 790 for flexural test and ASTM D570 for water absorption test. To determine the porosity percentage, mercury porosimeter test was conducted. The result shows that higher the water plaster ratio resultant in higher porosity percentage and water absorption. The result showed that, the proposed porous resin has great potential in replacing plaster mould as mould material for CSRM system. The mould has a uniform open pore to enable the filtration process to take place within the mould and the slip and has a great mechanical strength. However, porous resin is still a semi-permanent mould with definite service life.
