No Bake is a casting
process that uses chemical binders to bond the castings sand. The
sand is then transported to the mold fill station in preparation for
filling of the mold. A mixer is then used to blend sand with the
chemical binder and the catalyst. When the sand exits the mixer, the
binder begins the hardening process. After the compaction process, a
rollover process is used to remove the mold from the pattern box.
The mould is then readied for handling the molten metal. After a
shakeout process, the casting sand is taken away from the casting.
Then various procedures follow including the finishing and the sand
can be reclaimed by thermal means.
The chemical nature of the binders makes this a highly specialized
process that has to been handled with considerable expertise and
knowledge. At VJP, we have developed our expertise in the process
over the years and today are able to harness the potential of the
process to create casts of the highest quality and to a great degree
