Kleinewefers Kunststoffanlagen KKA melt roller calender: highest productivity and maximum output

Kleinewefers Kunststoffanlagen KKA - Know-how right from the... Calendering designates a process where rotating rollers are used to shape, calibrate and compress web type materials. Polymer melts are processed in KKA calenders to produce mono-film without carrier and to directly laminate this film onto various web type substrates. Exactly tempered rollers with deflection compensation ensure high-precision nip geometries and guarantee first-class products based on polymer PVC, TPO, TPU. By combining KKA calender technology with extrusion tools, the field of application is extended to...

Kleinewefers Kunststoffanlagen ... planning stage until production. KKA Magmatec melt roller calenders reflect our concentrated competence and worldwide market leadership. The idea behind this melt roller concept was to achieve film production and coating in one single process. The technology used for the KKA Magmatec melt roller calenders emerged more than 55 years ago and has been continuously advanced and refined since then. In terms of mechanical and process engineering, the status quo of the MRC has been developed by KKA also on the basis of know-how from companies like "Zimmerplastic"...

KKA Magmatec in the process of production Coating plants operating with melt rollers can be used to produce a variety of products and widths from 1,300 up to 5,500 mm. The plants can be optionally equipped with 2- or 3-roller calenders. Application fields include coatings ranging from 80 to 2,000 g/m² of open and closed mesh or woven fabric, stitched fabric, knitted fabric, felts, nonwoven and paper with PVC, TPU, TPO (PP, PE), CPE, elastomers etc. Moreover, 3-roller calenders can also be used for film production, e.g. based on PVC, PVC/ABS or scrap with regrind material.
