The bimetal extruder has a hard protective coating about 1-2 mm thick. It is suitable for working on difficult-to-machine extruder pipe surfaces for a durable and reliable experience associated with production. Recyclable non-specific plastics or produced plastic tubes have the potential to rely on extruders. When purchasing a new extruder, a bimetallic screw barrel is required, which provides a choice between options such as recycled plastic or sized plastic.

These options are cost-effective and can even be serviced without sacrificing extruder functionality and performance. It is the best source for optimum performance, moisture resistance, fatigue resistance, strength, and several other 
controlled processes. Over the life of the machine, several factors put additional stress on the extruder.

When it comes to materials to produce bimetallic products, the only options are recycled or substandard raw materials. Using recycled materials to produce drip irrigation or regular plastic pipes is considered an environmentally friendly option. It is eco-friendly as it helps reduce waste, which in turn helps reduce the cost of the materials used.

However, regrind plastics are more likely to contain trace amounts of impurities, particles, and other plastic-related additives, which can cause additional wear and even random performance when extrusion is performed. The recovered material was found to be rough, impure, and rough on the bimetallic extruder screw barrel, providing smooth functionality even after prolonged use of these materials.
