Machinery + Planning Inc. offers an optimised 3,000kN MHF 700D/300 horizontal injection molding machine, which is ideal for economical production of seals and O-rings, for example. Thanks to its extreme opening width with extended tie-bars, hydraulic nozzle lifting (Maplan Duale) with variable nozzle immersion depths and an extremely short nozzle, the machine provides extremely high flexibility and compatibility when using very different tool concepts, regardless of whether the tools are thick, flat, large or small. This makes it a universal machine with the maximum degree of freedom.

For demanding applications, such as cold runner engineering, the new MHF 700D/300 provides space for up to six tempering devices to be integrated into the machine frame. The machine can be equipped with a cold runner mold supplied by Maplan´s tooling partner OR.P. Stampi S.r.l. A little highlight here are the individually addressable needle shut-off nozzles, which are necessary for managing cavities with different volumes in one tool. The configuration and control of the nozzles is fully integrated into the new control system.

The shown tool has eight cavities of drip mats in two different volume sizes arranged in a 4+4 concept. The smaller ones contain around 12 ccm whereas the bigger drip mats consist of approx. 17 ccm of platinum curing HTV silicone. Standardised interfaces facilitate automation via handling and interlinking equipment. The time-proven FIFO units score points whenever perfect item quality and fast material or color changes are required. A newly designed strip inlet ensures that the material is fed reliably, even for delicate rubber mixtures. The switch cabinet is mounted to absorb vibrations and has an integrated cooling device to protect all control components reliably. The show-stopper here: The cabinet can be pivoted to improve access to the main hydraulics. The frame concept can be extended by one or several additional hydraulic systems.
