The CRB is a tool which multiplies the number of injection points in the moulds for rubber, silicone or other thermosetting material. Its major interest is to allow a significant saving of material thanks to an injection as close as possible to the cavity, the hot runners being practically non-existent.
The CRB has also the following
advantages :
- better control of the temperature of the
compound in the global injection system,
- decrease of the injection and
vulcanisation time,
- decrease of the demolding
time of the runners,
- decrease of the injection burrs,
- better balance of the full-filling of the
mould,
- possible increase of the number of
cavities,
- possible injection of hard material,
- productivity increase,
- reduction of the production costs
