ELMET premieres TOP 700 LSR dosing system at NPE 2024

At NPE 2024, ELMET premieres its new, ultra-compact TOP 700 dosing system for injection molding liquid silicone rubber (LSR).

The new system is the most compact 20 liter system on the market that provides the same high precision dosing of silicones and additives as the company’s flagship TOP 7000 Pro dosing system.

High performance with cost efficiency

The TOP 700 can achieve delivery rates of over five liters/minute at a maximum pump pressure of 210 bar, enabling short cycle times both when filling larger parts and with large numbers of small cavities.

Additives and colors can be dispensed from 1, 4 and 20 liter containers. In order to achieve the dosing precision that is particularly vital for very small parts, the volumetric meter for colors has a resolution of below 0.1 μl/l.

With optimized design of the follower plates, just 40 ml of residues are left behind when the 20 liter drums have to be changed, resulting in material utilization of up to 99.8%.

Cost of production is low as the system requires very low energy consumption of less than 50 Wh and minimal compressed air consumption. Moreover, maintenance cost remains low as all mechanical components are with a design service life of 20 years or more, as well as a modular structure and particular ease of servicing.

Reliable, versatile and safe

The new dosing system is ideal for applications requiring the highest levels of cleanliness such as medical technology, personal care, foodstuffs and optics. Virtually abrasion-free pumping also prevents metal particle contamination of the LSR.

As it can handle viscosities of between 0.001 Pas and 2000 Pas (shear rate 10/s) or 16,000 Pas (1/s), there is no limits to the consistency of the processed LSR. Its optionally OPC UA- and Euromap 82.3-compliant control system can be seamlessly integrated into the injection molding machine’s own control system.

The new TOP 700 also ensures safety by meeting the stringent requirements EN ISO 13849-1 which applies to machines and control systems. To avoid operating errors, the drums can be changed fully automatically from the drum rim from three sides within 2 minutes.

In addition, intuitive operation of the system, use of simple clamp connections, a guided drum change procedure and an integrated cooling system imply low-skilled and easy operation.
