> Ideal for thin walled parts and over molding large inserts. > Vacuum chamber surrounds the tie bars enabling powerful vacuum of entire clamp area. > Eliminates defects caused by trapped gases and flow lines. > Enables simpler tooling - no vacuum channels or seals are required. > Insulates mold to reduce heat loss / inconsistency and save energy. > Assists in the reduction of mold fouling. > Shutter at front of press and standard mold slide enable easy access to parts
