Our post-processing processes for extruded plastics
Post-processing of extruded plastics requires comprehensive materials expertise, years of experience, and technical processes optimized for the particular requirements posed by the material. The main post-processing processes that we offer in-house and in conjunction with our partner companies are described below with reference to examples.
Low-flash cutting of extruded plastic profiles to length; mitre cutting possible
The rotation, stroke and tooth pitch of the saw blades are optimized for the material. The possible wear is taken into account, for example for sawing of glass-fibre reinforced plastics. This enables the plastic profiles to be cut to the desired length with low flash.
Our machinery and equipment: Pull-push saw, sliding mitre saw
Utmost flexibility and precision for custom requirements
The material of the milling tool, machining speed, cooling and stress-free workpiece restraint fixtures are matched perfectly to the plastic’s specific properties, thereby preventing overheating and deformation of the parts.
Our machinery and equipment: Double-column CNC milling machine for high machining speeds
Optimum preparation of threaded and push-to-connect joints
Holes, of any geometry – round, elongated, square, hexagonal, etc. – are also machined with cutting speeds, cooling and workpiece restraint fixtures geared to the plastic used. Optimum results are thereby assured.
Our machinery and equipment: Bench drill, double-column CNC milling machine, special machinery
Production of apertures to custom specifications and with low flash
Punches, dies and workpiece handling are adapted to the specific requirements of the plastic and reflect our comprehensive material expertise and many years of experience. Punching free of deformation and reliable series production are thereby assured.
Our machinery and equipment: Hydraulic punching press, rotary punching machines, computer-control punching press
Precision edge smoothing following sawing, milling and punching
The extruded products are treated in low-stress processes either manually or with use of a range of machinery, depending upon the specific requirements and properties of the plastic.
Our machinery and equipment: Brushing station with brass brushes, portable dry-ice jet
Protection against damage during transport and further processing
A film can be applied to the profiles at the extrusion stage to protect the surfaces. Alternatively, the customer’s choice of film can be applied manually following extrusion.
Our machinery and equipment: Extruder with additional function for automated film application
Self-adhesive assembly surfaces
Application of self-adhesive elements in accordance with custom requirements
Like the protective film for surfaces, self-adhesive tape can be applied to the plastic profiles during the extrusion process. The strong adhesive force of the tape enables it to bond without difficulty to a range of surfaces.
Our machinery and equipment: Automated application function added to the extruder
Hot forming enables the ends of extruded plastic profiles to be widened with a special punch to create a spigot and socket joint.
The challenge lies in adapting the process to the particular thermal conductivity properties of the plastic used, such that only the region to be formed is partially melted, and the geometry is formed with high mould fill and without cracking.
Our machinery and equipment: Moulding tools with integral heating, cooling, clamping and feed
Printing of the plastic surface to custom specifications
We use proven, low-stress ink-jet and laser printing methods to apply durable markings and labelling in a range of colours to extruded plastic products.
Our machinery and equipment: Ink-jet printers, laser printers
High-quality packaging for safe transport
The plastic profiles are vacuum-sealed with aluminium composite film to protect them against damage, soiling and damp during transport and storage. Cardboard packaging, multi-packs, mesh boxes, long pallets, etc. are used.
Our machinery and equipment: Sealing tongs, suction cup lifters, etc.
