Modular design offers a number of arm lenghts, rotation options, stand height, and number of movement axes (up to seven). Direct lead-through teaching or CNC-type programming are available. Special features can include automatic parts identification to select spray pattern; closed-loop monitoring and adjustment of fluid flow, temperature and catalyst/resin ratio; low-level alarms for all ingredients; glass strand breakage alarm; ultrasonic part-position sensing with automatic offset adjustment; complete load/unload indexing systems.


Builds a standard line of robots to fit injection molding presses in the size range from 20-to 2000-ton clamp capacity. Robots can also be customized to fit particular applications. The complete line includes sprue pickers; vertical-entry, 3-axis pick-and-place robots; and side-entry, pick-and-place robots. Company supplies all-pneumatic robot models (x, y and z axis), or all-electric-drive robots, or a combination of pneumatics on the arm and head (x and z axis) with electric drive on the beam (y axis). Company will also design and build complete turnkey systems with downstream automation coupled to its parts-removal, vertical- and side-entry robots. (See data sheet p. 352.)


Provides robots specifically designed for vertical presses. A carriage telescopes into the open daylight, carrying new material charges in with it. Loading of phenolic, melamine, or polyester BMC materials is accomplished with load cups or loading boards. Granular or preform load systems are available. Charge placement in the mold can be precise when using preforms or BMC charges. Company's BMC extruder can be used to pre-size polyester BMC for loading. Preheating systems are available for phenolics and melamines, as well as other thermoset plastics. An air blast or optional brushes are used for mold cleaning. Part removal is accomplished after ejection from the top or bottom by suction cups, grippers, comb, or drop board. Parts are normally sensed to insure a clean mold before loading takes place. Molded parts can then be sequenced for further processing. Robot is interchangeable between presses and is mounted on wheels for easy removal for mold changes and manitenance.
