Liquid Gravimetric Dosing Machines

MCLiquid: reliable and spill free liquid dosing

image12

 

Coloring with liquid can be a challenging operation. It all depends  on reliable dosing, often at extreme low dosage rates. Variation in  viscosity of liquids and spill-free handling are the main issues. 

Movacolor has developed a modular liquid dosing system with one  universal motor unit, two pump types and several spill-free packaging  concepts. This offers you the possibility of composing your optimum  configuration.


Peristaltic pump

The peristaltic pump is used in processes with frequent color change. Available as gravimetric & volumetric dosing system.

   

Advantages: 

  • Easy color change
  • The gravimetric system provides a constant output
  • Low dosing rates
  • Easy to clean


Disadvantages:

  • Limited life time of pump hose
  • Limited pressure build-up
  • In volumetric mode the output depends on viscosity

A gravimetric peristaltic pump is an ideal combination for color  changes. The gravimetric control automatically compensates for the  disadvantages of a peristaltic pump: the output of a peristaltic pump is  heavily depending on the viscosity of the liquid, the type of pump hose  used and the age/ wear of the pump hose.

Mono pump/ gear pump

In case of long runs we advise to use a mono pump. Available as gravimetric & volumetric dosing system.

   

Advantages: 

  • long life time
  • can build pressure up to 10 barg
  • output independent of viscosity
  • easy change of pumps
  • extreme low dosing rates (gear pump)
  • high dosing rates (mono pump)


Disadvantages:

  • system should never run dry
  • difficult to clean

Both systems are also available in a volumetric configuration. 

To complete the package we supply in-line mixers and special nozzle adapters for easy installation and easy cleaning. MCLiquid: your total liquid dosing concept.

  

Features MCLiquid

  • 100% traceability by gravimetric control
  • 8” full color touch screen 
  • Automatic material calibration
  • Recipes storage function
  • Free choice of pump type and packaging concept
  • Total integrated solution including
    mixers and neckpieces
  • Industry 4.0 ready

Inline mixer for injection molding or extrusion

image13

 

For the most PET injection molding or extrusion  processes the normal inline dosing principle works without the use of  inline mixers. But when the plasticizing screw of the extruder or injection molding machine has a limited homogenization capability, it is beneficial to use an inline mixer.

A selection from our inline mixer product range (for information about these products, please contact our dosing specialists):

 

Optimum performance with Inline mixers

Whether or not to use an inline mixer depends on the kind of plastic  production process. The dosing specialists of Movacolor can give you a  professional tailor made advice based on your type of production  process. Movacolor has developed a range of inline mixers that perform  optimal in homogenization and coating of low melting colors or  additives.

Motorized inline mixers

The motorized inline mixers in the Movacolor product range are ideal for use in the most demanding applications for  both injection molding and extrusion applications. The complete inline  mixer construction is made of robust stainless steel, together with the  small 3-phase motor this results in a compact, solid and durable end  product. The inline mixer is available as single inline mixer or  combined water-cooled neckpiece inline mixer.


Inline mixers for PET

For PET applications a special inline mixer is designed with  integrated water cooled flanges. The inline mixer is available with the  50 mm outlet or the 90 mm outlet depending on the size of the PET  processing machine. Both type of inline mixers can be carried out with  an extra water cooled flange for mounting a second Movacolor dosing  unit.

Easy cleaning of inline mixers

The inline mixers have a user-friendly design which makes it easy in  use. The disassemble process of the inline mixer is made simple. Just  remove the 3 phase-motor of the inline mixer with the counter rotating  mixer blades and all parts are reachable for maintenance and cleaning.

Inline mixers and hybrid systems

With a MCHybrid 30 or MCHybrid 200 blending and dosing system the main materials or regrinds  are mixed in a compact gravimetric batch blender. Next to that the  additives are dosed gravimetrically in-line, directly on the throat of  the IMM or extruder. 

By using the blending and dosing technology of the MCHybrid 30 and MCHybrid 200 in one machine, you are able to control the capacities of the main materials in any given ratio and dose materials like regrind and masterbatch at low percentages with great accuracy.
