The HPM Division of Taylor's Industrial Services has a rotating, movable platen option for its Freedom Series injection molding machines that can reduce cycle time for insert molding, multicolor, coinjection and other processing by 30% to 35% and improve productivity by up to 133%, says HPM.
The lock-up of both platens ensures no pushover on the desired closed centerline position.
One way to ensure proper mating of the tool halves at the parting line is simply by having a level molding machine and parallel platens.
Options: Wide platens for models of 720 tons and up, tiebar puller, quick mold change.
Features: Clamp force applied at center of mold platen, hydraulically operated blow pins, top blow, single and dual stations, programmable control.
Heating platens with heat pipes was also considered.
Options: Heating, floating upper platen, PLC controls for different accuracy levels, vacuum cabinet for entire press, high-heat platens (up to 600 F), closed cooling system, data recording, multiple daylights.
Features: CFT--Proportional hydraulic control, 0-90[degrees] frame tilting; DFT--180[degrees] opening of upper platen, integrated pressure cushion; UFT--Proportional hydraulic control, programmable incline angle; SFTR--High clamp force, upper platen tilts 45d, frame tilts 90[degrees]; SFT--Upper and lower platens tilt 45-90[degrees].
Furthermore, the energy balance for a heating and cooling process is many times more favorable in comparison to the press for intermittent processing, because the hot platens in the ContiRoll are parted, according to the company.
These applications showed off the multi-functional flexibility of stack-type molds with one or more rotating turrets between the fixed and moving platens.
The clamping system guarantees plane-parallelism of both heating platens.
Other features include high-speed rotation and high-speed platens with variable-frequency electric drive and closed-loop control that is said to provide upper and lower platen repeatability within [+ or -] 0.
