Q1: What are the advantages of twin screw plastic extruders compared to single screw extruders when used for profile metal production?
A: For strict profile extrusion applications, parallel twin screw plastic extruders have significant advantages. Its excellent mixing and conveying ability ensures sufficient homogenization of fillers, colorants, and recycled materials. The final plastic profile exhibits excellent mechanical properties and surface smoothness, which is difficult to achieve with a single screw configuration.

Q2: How does your plastic profile extrusion machine handle recycled materials?
A: Our plastic extruder adopts a reinforced screw geometry design and exhaust system, which can efficiently process recycled materials. The optimized screw configuration achieves mild and sufficient plasticization, while the vacuum exhaust port effectively removes volatiles, moisture, and degradation products. This allows for the addition of 30% to 50% post consumer or industrial recycled materials during the extrusion process of plastic profiles without affecting the quality of the finished product.

Q3: What is the thickness tolerance that your company's plastic extrusion production line can achieve?
A: Thanks to advanced automatic die heads and precision three roll calenders, our plastic profile extrusion machine can achieve a thickness tolerance of less than ± 2%. This high precision is particularly critical for hot forming applications - uniform profile thickness ensures consistent heating and reduces material waste during the forming process.

Q4: Can plastic extruders be customized for specific material formulas?
A: Absolutely possible. One of the major advantages of our plastic extrusion equipment is its high degree of customizability. We provide custom designed screws, barrel structures, and feeding systems to accurately match your specific material formula - whether you are processing high filling masterbatch, engineering plastics, or have high requirements for the final board's barrier properties, we can meet them.

Q5: What is the delivery cycle? What after-sales services does Nanjing Kelongwell provide?
A: The delivery cycle of a standard plastic profile extrusion machine is usually 60-90 days, depending on the degree of customization. As a professional manufacturer, Nanjing Kelongwell Chemical Machinery Co., Ltd. provides comprehensive after-sales service, including installation guidance, on-site debugging, operation training, and sufficient spare parts inventory to ensure that your production line always operates at its best.
