Helical speed reducers with hardened and ground gears assure high efficiency and help cut energy costs. First in First out and overlapping melt flow type is employed for machines of size VBM 250 and larger. Sliding parts are hardened and ground.
Special design ensures straight parison with litttle sag or curl.
High clamp force to assure fine parting lines and quick clean trimming and finishing of mouldings - even irregularly shaped ones. Hydraulic system is simple in design while ensuring high efficiency to reduce energy costs. Automatic control ensures consistent quality of products. Machines can be operated by less-skilled personel. They also have proportionale hydraulic control for mould movement and other functions.
