Product category: Volumetric dosing and metering equipment, Gravimetric dosing and metering equipment

PLASTICOLOR Dosing Units

The PLASTICOLOR modular system has four dosing unit sizes with a performance between 70 g/h and 3,500 kg/h.

Dosing units can be used as individual dosing units, but can also be used in

  • Colour change systems
  • Dosing systems
  • Volumetric mixing stations
  • Gravimetric mixing stations
  • Gravimetric dosing-/mixing stations

PLASTICOLOR Color Change System

Changing colours by a flip of the switch: this feature is provided by using 2 or more PLASTICOLOR units.
Standard colour change systems consist of 2 to 8 PLASTICOLOR units, mounted at a common neckpiece. Special colour change systems for more than 8 components can be designed and supplied.
Every single unit is provided with a slide. The control enables you to shut down one dosing unit and to start another one at the same time.
This also closes and opens automatically the according slides. The metering of undesired material into the neckpiece is avoided. The second unit starts dosing exactly at the point where the first one stopped. The production is not interrupted.

Benefits of colour change systems:

  • Immediate colour change during production
  • Simple handling and operation
  • No more excess of pre-mixed material
  • Avoiding scrap production and waste

PLASTICOLOR Dosing Stations

A dosing station system combines not only dosing units, but all components from the machine feed point, such as the hopper for the main material, the hopper loader, the magnetic separator etc. It could be a multiple-component dosing system (e.g. catalyst/colour) or a multiple colour change system, for example.
Like in the individual unit, the main material flows freely into the screw of the processing machine. The screw of the PLASTICOLOR device feeds the material to be dosed into the main material flowing through the neckpiece.
The materials are mixed very consistently (homogenised) in the production machine. The short distance between dosing and processing prevents the materials from separating.

Dosing systems are mainly suitable for processes where the speed and throughput of the processing machine are constant to a large extent.

PLASTICOLOR Mixing Stations

Standard mixing stations consist of 2 to 8 PLASTICOLOR units. Special mixing stations for more than 8 components can be designed and supplied.

The following are available:

  • Volumetric mixing stations
  • Gravimetric mixing stations
  • Gravimetric dosing-/mixing stations
The modular design of the systems facilitates the easy and inexpensive extension of existing mixing stations or conversion from volumetric into gravimetric operation.

PLASTICOLOR Throughput Measurment Systems

Gravimetric systems and the measuring and control equipment associated with it, offer a wide spectrum of possibilities. They improve product quality, save material, and document production processes.

A number of control strategies are available, for example:

  • quantity control
  • meter-weight control
  • G.S.M. (Gramme per square metre control)
  • ramp-up and ramp-down control.
In connection with a suitable personal computer, it is possible to record, display, evaluate and print all relevant data. The throughput measurement can be combined easily with an existing PLASTICOLOR mixing station.

PLASTICOLOR Drying Systems

DESICCANT DRYING SYSTEM DDT
Desiccant-type systems work according to the absorption principle, i. e. closed-loop heating and dehumidification by a chamber containing drying agent.

HOT AIR SYSTEM IHT
IHT series dryers make use of environmental air. Hence, the drying result depends on the environmental conditions (relative air humidity and temperature). Hot air systems are mainly used for pre-heating or drying non-hygroscopic materials.

About us

Company details

Woywod – Endless Opportunities

Originally founded as an engineering company for extrusion technology at the end of 1970, Woywod Kunststoffmaschinen GmbH & Co. Vertriebs-KG has manufactured and sold PLASTICOLOR equipment and systems for the plastics processing industry since 1980. PLASTICOLOR stands for precision, durability, efficiency and an optimum cost-benefit ratio.

Next to PLASTICOLOR single dosing units, color change systems, volumetric and gravimetric mixing stations, Woywod also offers hopper loaders and driers (hot air and desiccant drying systems). Our modular design (add-on system) of equipment and systems for the mechanics and the electronics makes it possible to create individual, solution-oriented systems which are tailor-made for customers using.

PLASTICOLOR products are known and sold all over the world through a network of agencies, wholesalers and sales representatives. Innovative flair, technical advancement and practical solutions continue to be our strengths for the future.
