Resin Coated Sand Core Mould Making Used for Making Various Core Making or Shell
1,What is resin coated sand?
Resin coated sand, is molding materials that used for making various sand cores or molds,such as cylinder block, cylinder heads, watercourses, exhaustmanifold core and so on. It is silica sand mixed with core oil (linseed oil, resin, mineral oil) and other binding materials (dextrine, corn flour, sodium silicate). It has remarkable compressive strength.
Different type of precoated sand is suitable for different casting, we will design an unique formula for every custom.
2,The advantage of resin-coated technology
Advanced resin-coated technology assures superior quality, uniform curing and fewer casting defects Reduced wall thickness drives down sand and resin usage, minimizes waste Better heat transfer capabilities shortens cycle times and cure times Better shakeout properties reduces cleaning requirements and energy usage.
