The motor is water cooled and constantly monitored by temperature sensors that ensure the optimal temperature throughout the system. At the same time it allows an excellent control of “mould safe”. This motor, developed in cooperation with Moog, provides the system with torque and speed that result in a very fast and precise mould movement, perfectly controlled in acceleration and breaking.

The rotation of the system is provided by a brushless motor specially designed with hollow shaft installed directly on axis to the system, controlled by an inverter. The clamp closing/opening movement is operated by an electromechanical axis based on the technology of a screw ball. The lubrication of the screw ball is entrusted to a special pump developed specifically for this application, and completely independent of the lubrication of the links. Buy Our PET Preform Bottle and Plastic Caps for your Business and Specific Needs.It provides innovative solutions to improve efficiency of your logistics. The moving platen is supported by adjustable sliding blocks to ensure less friction and complete safety of the mould. This bottle-making method is called a two-step method, that is, a method of forming a preform through injection molding, and then forming a PET plastic bottle through blow molding. The lubrication system is cyclic and programmable by points, with safety devices that allow constant monitoring. PET preforms are processed by blow molding to form plastic bottles. The clamping system is based on a five-point double toggle with steel links and special bronze bushings. considerable energy savings, that come from the fact that the motor is automatically switched-off (thus reducing consumption to zero) once the accumulator is full.

Therefore the several advantages of this application are: This procedure allows to obtain maximum speed performance otherwise impossible, while maintaining precise and constant control on speed and pressure. A very small size motor, coupled to a pump with internal gear, provides for the recharge of the accumulators and creates the optimum conditions of use. The switching on/off of the pump is controlled by an inverter that shuts off the motor once the required level has been reached, thus minimizing power consumption and maximizing the system efficiency. The axis control, realized by a close-loop control servo valve (Moog), ensures the optimization of all the conditions required even in the most sophisticated moulding processes. This is the most complex movement of the machine and it determines the quality of the moulded product.

The injection unit is based on the technology of a rotary piston, hydraulically balanced under accumulators, without any thrust bearings.
