An environmentally friendly and resource-saving cleaning process can only succeed with a cleaning concentrate. For example, the ground start-up scrap can be processed with a cleaning concentrate into a cleaning granulate. In this way, the raw material […]
Sealing surfaces occur when two components meet. E.g. nozzle and cylinder head or cylinder head to cylinder (see illustration). Sealing surfaces must be absolutely flat, even and undamaged so that they seal without gaps at their boundaries. If this is […]
Cleaning granulate instead of cleaning concentrate?
The basis of a cleaning granulate in plastics processing is polyolefin. When changing color or material, e.g. from POM black to ABS beige, with a prepared cleaning granulate, the polyolefin comes into the system as […]
In addition to flow dead zones, damaged metal surfaces are also a cause of cost-intensive cleaning processes. Damaged metal surfaces can be found along the entire path of the plastic from the hopper to the cavity or to the exit […]
Leading granule manufacturers admit that they cannot produce granules without black specks. In the complex manufacturing process, flow dead zones cannot be avoided. In these zones with little to almost no melt flow, the plastic burns due to excessive thermal […]
