German dosing systems and components company ViscoTec has announced the release of a new treatment and supplying system for its 2-component dispenser. The new system, called ViScaFeed is a material treatment and supplying unit for fully automated applications. Just like its ViScaMix system, designed for manual potting applications, the new system was developed by Danish company Scanmaster. It feeds the company‘s 2-component dispenser, and can be used for potting and encapsulating electronic components, either by robot or another type of gantry solution, Henning Pedersen, CEO and owner of Scanmaster, explained.
The system has the same features as the ViScaMix. Only the dosing pumps in the system have been replaced by the larger 3VMP18 in order to increase supply capacity. If production numbers increase, the unit can be integrated into an existing PLC of a robot or XYZ table, the company explains. In this case, the system would take over both the treatment and the supply of the materials to the 2-component dispenser mounted directly on the gantry.
According to the company, ViScaFeed is well suited to abrasive, filled or shear-sensitive fluids and pastes – regardless of their viscosities. The two-component materials can be dispensed with a mixing ratio of 1:1 to 10:1.
The treatment and supplying system is controlled via the ViscoTec ViscoDos-2K-V by means of 2-point pressure control. The individual dosing parameters for the progressive cavity pumps in the dosing system (dosing quantity, volume flow, mixing ratio, calibration, pot life warning, and so on) can be conveniently set via the external controls. The dosing itself is precise; the mixing is done by common static mixers. Possible dosing speeds range from 10 to 600 ml/min, depending on the pump combination and mixing ratio.
The features of the system at a glance include:
Automated potting processes (including material treatment and supply)
Production of high quantities due to minimal downtime
Gentle dosing of materials – due to the ViscoTec endless piston principle
High precision dosing – regardless of viscosities and viscosity changes
Easy assembly of the 2-component dispenser on robots or axis systems
Material supply with 24 l stainless steel vessels (pressure tank max. 4,5 bar)
Filling through manual refill or vacuum suction.
