Instrumentation & controls has introduced hydraulic automatic compression moulding press of four-column type. It includes machines of 15 tonne, 30 tonne, 50 tonne and 100 tonne capacity. The presses are equipped with large platen area, long stroke and fast cycling time. These machines operate using push button with full automatic cycle and provision is incorporated for inching down for tool setting. The machines can be set with heaters, temperature controllers and/or with air operated up and down guards in two parts. As a further safety feature air operated chokes can be incorporated and these are electrically interlocked with the action of the guard. The basic machines have eight tapped fixing holes in the top and bottom platens but other holes or tee slots can be provided at extra cost. The illustration shows the 30 tonne press and this press have an electric heater unit in each platen. The electric control panel can be set on either side of the press and an additional twin cycle button can be fixed on the opposing side, if required. The illustrated press is useful for making polymer film for testing in laboratories. There are three timers and pressures control to have air removal initially and then compression for a given period. It is fully automatic press manufactured for a polymer-manufacturing unit.
