As with the NR-3, STOLZ’s Round System has been adopted to supply and circulate dehumidifying air of –50˚C generated by a heatless dry air unit through a closed system.
An N2 gas connection port (ø6 mm) comes as part of the standard equipment for introducing N2 gas. (N2 gas cannot be circulated at the same time as dry air from the heatless dryer unit.)
The closed conveying system transfers plastic to the molding machine over an airtight circuit using suction force. Because secondary air is not drawn into the circuit, it shuts out moisture found in the surrounding environment, thus enabling thorough drying.
Contamination-free drying for maintaining clean room cleanliness is provided via a 3 µm fine-mesh filter element, clean blower and high performance line filter (recommended option).
The material supply blower is inverter-controlled, making it possible to adjust transport speed so as to minimize material damage and dust generation. For specifications, contact us.
Tank for stocking virgin optical resin material.
Pellet tank KA/KV/KX
A line filter can be installed on the molding machine hopper to thoroughly remove dust.
Line filter GF/GX
Specify the length of the bare stainless steel flexible hose used to convey stock. (Ferrule ends, 0.5 m markings from 1 -- 4 m, lengths over 4 m possible by connection) Suction hoses of the same length as material hoses are automatically selected.
Machines can be started and stopped automatically by simply setting the days of the week and times that the machine should run.
Integrated signal lamp (red) for signaling overloads or temperature errors. Incorporates warning circuitry.
Purpose-specific attachments are available.
