performance starve-fed compounding extruders with a Somos Gramix S gravimetric dosing system for up to seven components. The control system uses a touch
screen panel to enable simple progam- ming of system parameters such as line speed, extruder throughput, pellet length, dosing, drying and conveying. Protec says that up to 1,000 recipes can be saved locally, while communication options include internet and WLAN. ❙

Sikora will display its Purity Scanner for
Process Control will demonstrate its new PEX dosing system at Chinaplas. The system allows PE powder or pellets to be mixed inline with stabilisers, additives and peroxides for production of crosslinked pipes and tubes. According to the company, the key feature of the system is its gravimetric dosing technology, which allows liquid peroxide to be dosed at levels as low as 20 g/h. This is achieved through the use of special capillary tubes in the mixing chamber. The company says the inline dosing system eliminates the need for a premix and the associated risk of peroxide volatilisation. ❙

ProTec Polymer Processing will introduce a five-strand laboratory line for development of high quality long fibre reinforced polymers (LFTs). The Industry 4.0-capable lines use the company’s Somos excellence controller and are designed to provide LFT compounders with a flexible development option for testing and scaling up new formulations. Compared to its production lines, the lab lines
feature a narrower die able to handle five glass fibre strands (three if processing carbon fibre). Otherwise, the design is similar, which means they use high
inspection and sorting of plastic materials. This online system combines an X-ray camera with an optical camera system and is claimed to be the only available technology for detecting contamination on the surface as well as inside plastic pellets. Contaminated pellets are automatically sorted out. The latest version of the technology is the Purity
Scanner Advanced, which can be optimised to specific sorting tasks with the addition of optical high-speed cameras as well as X-ray, colour and infrared cameras. The company will also show its Purity Concept
system, developed for low throughput applications. These can be equipped with X-ray, optical or infrared technology and can detect contamination in pellets, flakes and films/tapes. ❙

Taigang Plastic Machine will show its high speed mixer and cooling blender, which is designed for premixing powder and granular materials prior to plastics processing. The mixer is said to provide a uniform mixing throughput the batch and offers good plasticiser absorption in PVC blending applications. It features a stainless steel mixing chamber and is designed for fast and effective cleaning, featuring a self-cleaning discharge system. The units can be used for manual or automatic production. ❙
