Why Bimetallic Extruder Screw & Barrel is important?
Saving the cost in the production of pipe manufacturing is very important. The quality of the product is only good if the machine is good. So it is advised to invest in the best machinery components.
We have seen that many plastic pipe manufacturers want to know that why an extruder machine with a bimetallic screw and barrel is important. The answer is the bimetallic screw and barrels have a hard protective coating typically of 1-2 mm thickness. This made it easy to work with hard materials used in the extrusion process and also it provides an excellent product experience.
Now the question is
Why you need a strong Extruder?
When the plastic pipes are made with recycled or off-spec plastics, it creates more pressure on the extruder machine. When you buy a new extruder, it is best to choose a bimetallic screw and barrel as you can use cost-saving materials like recycled or some off-spec plastic without compromise the functioning of the extruder machine.
The bimetallic screw and barrel provide the best extruder performance, strength resistance against fatigue, and enhanced process control. In the operations and life span of extruder machines, there are various factors affecting them.
One of them is
Recycled or Off-Spec Raw Materials
The use of recycled materials for producing drip irrigation or plain plastic pipes is a great initiative to save the environment by reducing waste. This also reduces the overall material costs.
But these recycled materials contain impurities, particulates, and additives that cause or show weird behavior during extrusion. And if these recycled materials are rough, unclean, and harsh, the bimetallic screw and barrels provide smooth production with these types of raw materials.
Devikrupa Group provides 3-layer Cross-head. And with them, pipe manufacturers can reduce the cost of raw material by replacing up to 80% virgin material with raw material. In the crosshead, the middle layer contains recycled plastic while the inner and outer layers made from 20% of virgin material. This is highly suitable for carrying drinking water as recycled part does not come in contact with water. Manufacturers also use up to four colored stripes.
The PVC is the world’s third most widely produced synthetic plastic polymer. Without bimetallic components the PVC raw materials case strain to the extruder, that’s why the PVC extruder machines need twin screws. Choosing the PVC extruder machine with a bimetallic twin screw and barrel minimizes the wear, maintenance cost, and energy consumption.
What are the Advantages of High-Quality Extruder?
The best extruder has many advantages from economic to product quality. As the high-quality extruder requires less maintenance which saves production cost and maintenance of spare parts. Also, the extruder easily handles recycled or off-spec materials which saves raw material cost.
The extruder is the main component of the assembly and it directly affects the quality of the final product. The extruder requires less maintenance if operating is proper.
