Our metal detectors for the plastics, rubber and chemical industries
reliably detect pieces of metal and metal inclusions – regardless of the
material – and automatically remove them. In doing so, they play an important
role in protecting machines and tools, boosting production reliability and
ensuring high-quality products.
Machine protection: The plastics, rubber and chemical industries often use expensive equipment, such as injection-molding machines, calenders, extruders and blow-molding machines. The continuous operation of these machines is tremendously important to a company’s profitability. However, operations can come to a standstill due to the tiniest pieces of metal, which can block melt filters, hot runners and nozzle tools, obstruct check valves or cause damage to plasticizing screws and cylinders. It is advisable to use metal detectors and separators to prevent these problems from occurring, because the timely detection and removal of contaminants increases process continuity and productivity.Quality assurance: In general, product purity is a key quality concern. In addition, quality issues can arise if metal contaminants lead to blockages in production equipment and cause too little material to be injected into the molds of plastic parts. In some segments, such as hygiene products, consumer protection is another argument for why metallic contaminants must be avoided at all costs. The use of metal detectors can lower the reject rate, prevent complaints and enhance customer satisfaction.
Our product range is modular in its design, which means that it can be adapted to all specific requirements that various manufacturing processes entail. We have standardized solutions for all process steps:
How easy is it to install the metal detector in the production line – and
how easy is it for your staff to operate the device?
In our white paper, we provide a detailed
outline of the issues, their causes and the necessary countermeasures for
eliminating metal contamination in the plastics processing industry.
Separately purchased recyclate often contains various different polymers as well as metal contaminants such as aluminum, brass, and stainless steel. Learn in our Case Study how Sitraplas has solved this problem.
