It can be performed with a host of materials, including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.
To the thermoplastic material of the ABS + PC glass fibbers, mainly used in the automotive industry.
Based on company´s materials of HRS (Hot Running Systems), one of the world's leading manufacturers of heated running system, the diameter of the main channel was changed to Ø 8 mm.
By this solution could be achieved non-waste injection, because the material will solidify only in the mould cavity, while the material in sprue is due to the use of heated running system still in a liquid state.
