Elmet: New LSR dosing system and new all-electric cold runner

Elmet is attending Fakuma 2021 as a one-stop shop supplier for the entire field of injection molding two-component liquid silicone rubbers (LSR). The centerpiece of Elmet’s presence is the new Smart mix TOP 7000 Pro dosing system. Also featuring at the fair will be Elmet’s newly developed all-electric Smart shot E cold runner system.

The Smart mix TOP 7000 Pro LSR dosing system is an all-round update of the TOP 5000 P. With a footprint of only 1150x790 mm, it is compact for dosing system suitable for 200 liter drums. The completely revamped pump unit has been further simplified and the number of parts minimized. Despite being capable of operating at pressures of up to 210 bar, the new unit’s slimmer design makes it significantly more compact. At the same time, this means that a significantly smaller volume of LSR is present in the system, so further increasing process reliability and reducing the purging volume. The reduced number of components facilitates cleaning and maintenance, while the reduced number of seals and the selection of optimized, FDA-compliant seal material reduce downtime.

Fully automated detection of follower plates and plate position now eliminates operating errors during drum changes and minimizes the corresponding handling time. According to the company, the optimized and recently patented follower plate design enables material utilization of up to 99.6 %. Instead of slide rails, full-surface slide plates facilitate drum changing, which can be carried out from three sides. The operator interface has been updated to a clearer structure. The material outlet is more readily accessible and has been positioned decoupled from the pump unit, so taking the load off the hoses leading to the injection unit.

The increased modular structure of Elmet’s new dosing system ensures a high degree of flexibility in adapting to changing requirements. Vie the new interface plate, the varied options available in the dosing technology range can also be retrofitted after delivery without the system having to be rewired. Another available option is the premium connectivity package which ensures worldwide access to the system via a web portal or associated app. In addition, a support request including a status report, which facilitates remote assistance by the Elmet support team, can also be initiated directly from the system. The integrated email function means users can be kept permanently updated about impending drum changes and maintenance work as well as any malfunctions.

Another new product at the fair will be Elmet’s Smart shot E valve gate cold runner system in which the needle is moved and positioned by a particularly compact servomotor. This allows needle opening to be adjusted in the µm range and the injection process into up to 16 cavities can thus be balanced with considerably greater precision than was possible with the previous pneumatically or stepping motor actuated versions. According to the company the technology enables a small nesting spacing of a minimum of 44 mm. Optimized cable management ensures that the cable duct can be removed as a single assembly without the need for a qualified electrician.
