Piston Metering Head

Highly precise metering system for dispensing, filling, applying, sealing, adhering, fixing and covering. For handling of: non-abrasive to highly abrasive, non-filled to highly filled, liquid to highly viscous single and two-component materials. Area of application: Exact metering with repeated accuracy in the electrical and electronic manufacturing sector. Advantages: Guaranteed constant precision Exactly reproducible mixing ratio of the metering amount Can be used for metering at atmospheric pressure and vacuum-assisted metering The volume flow is continually supplied at the right ratio and at the right quantity, from the starting to the stopping phase Hardly any cleaning and maintenance costs Rugged drive mechanics, precision motor, linear guidance and integrated metering monitoring sensors
Function: The vacuum-sealed design and the fact that the metering cylinders are filled by pushing and not drawing result in bubble-free metering (the cylinders are only filled using the material feed pressure). The piston diameter for the resin and hardener determines the mixing ratio, regardless of the temperature, air pressure or viscosity. The dispensing material is expressed through an exactly simultaneous piston movement and thus guarantees a constant mixing ratio.	The resin and hardener are firstly combined in the static mixing tube. There is therefore no reaction of both components inside the metering unit and thus no cleaning and maintenance costs. The sealing/washing fluid prevents the sealing elements becoming prematurely worn by picking up and rinse off the resin-filling-materials, which have adhered to the rear seal and cylinder side. Any damaging influences because of air moisture are prevented.
