Stuttgart, January 2018 – The extruder for powder coating production marketed as "ZSK 43 Mv PLUS world proven" comes with 43 mm screw diameter. It consolidates all the experience Coperion has accumulated while realizing more than 800 twin screw extruders for this field of application over the past 40 years.
The process section of the world proven model covers a very broad range of powder coating applications with three different screw configurations available. Typical throughput rates range from 250 kg/h to 600 kg/h for epoxy powder coating, and up to 750 kg/h for white hybrid powder coating or high-gloss products. For matte, highly filled polyester powder coating, the throughput rates are between 300 kg/h and 600 kg/h, for textured powder coating between 200 kg/h and 500 kg/h.
Standardized scope of supply speeds up ROI
The scope of supply is clearly defined. Apart from the process section it contains a volumetric feeding system and the main drive in the form of a water-cooled AC motor, an air-cooled frequency inverter cabinet, a mechanical safety coupling, the reduction gear, distribution gear, manifold, water cooler, the Siemens-based switchboard and the system startup. Additional powder coating screws and process engineering support from Coperion are optionally available.
The largely pre-defined structure of the ZSK 43 Mv PLUS world proven means that there are usually only four months between the receipt of the order, production at the Coperion facility in Stuttgart, and delivery, followed by startup at the customer's premises. What's more, the same capability of a custom-configured solution is provided at a considerably lower investment cost. Due to this fact and the high throughput rates, the return on investment can quickly be achieved. Coperion exclusively uses high-quality, tried-and-tested components – a strategy which results in high process stability with consistently good product characteristics and a long service life for all ZSK twin screw extruders.
