PUMP DOSAGE for liquids WD-SYSTEM – COLORING ON THE INJECTION OR EXTRUSION MACHINEFor liquid additives |
The devices of the WD series are high-precision dosing devices for assembly on the injection molding or estrusion machine.
Upon a shot signal from the spraying machine, the liquid additive (in most cases color) is metered into the main component to be freed.
The device works with peristaltic dosage
- Suitable for micro-injection molding
- Highly accurate by stepping motor with step monitoring
- State-of-the-art electronics and control
- Designed for 24 hours operation
- Material feeding directly on the intake of the spraying machine
ADVANTAGES
- Accurate volumetric dosing by stepping motors
- Constant metering
- Simple color changes
- Perestaltic pumphead
- Product-contacting parts optionally available in stainless steel (1.4301)
- Monitoring the dosed motor steps
- Large dosing range due to variable speed
- User-friendly color touch panel display
- Logbook function
- Export of data to a USB stick for external evaluation
BASIC EQUIPMENT
- Material chart: Variable
- Material: aluminum or stainless steel
- Electrical Connection: 230V/50Hz
- Product-contacting stainless steel (optional)
DOSING RANGE
- Motor speed 1% – approx. 0.01 gr / s*
- Motor speed 60% – approx. 1.50 gr / s*
* Depending on fluid material
The dosage on or at the machines gives the processors the flexibility they need to produce economically.
Option: WD system for powder and granulate
