The Shell Sand process or Croning process was invented by Dr Johannes Croning in Hamburg Germany in 1944 This process is the oldest core and mold making technology that utilizes synthetic resins Although many additional sand core and molding making technologies have since been introduced the Shell Sand process is still a very effective.Sand casting is a process that utilizes non reusable sand molds to form metal castings On one hand casting is a deceptively simple manufacturing process anyone who has formed castles at the beach knows sand can be used to make detailed shapes However in a foundry dealing with the heat of molten metal many factors must be considered for.Read More
Sand Core Making Cores are produced by blowing ramming or in heated processes investing sand into a core box The finished cores which can be solid or hollow are inserted into the mold to provide the internal cavities of the casting before the mold halves are joined.Mar 15 2016 ACIDS The acid used is a sulfonate organic acid (methanesulphonic and similar) in water solution chloride free There are four different types of acid (medium weak and very weak) the choice of an acid is essentially conditioned by the sand temperature (in summer a weak acid is preferable in winter a stronger one) but also by the type of sand of resin and by the required hardening speed.Read More
