  • Frequently Asked Questions
Here you can find some FAQ’s at Mechvis, our goal is to empower our sales team to provide focused, timely support that meets clients’ expectations efficiently.
  • What is the function of blown film machine?
    The blown film machine is equipment used to produce plastic films, widely applied in packaging, agriculture, industry, and other fields.
  • How do the screw and barrel work in a blown film machine？
    The screw and barrel of the blown film machine are mainly responsible for feeding the plastic pellets from the hopper into the blown film die. Through continuous forward pressure and the heating elements around the barrel, the plastic pellets are melted and pushed forward.
  • Is remote troubleshooting or technical support available?
    Yes, we offer remote diagnostics and online technical support to quickly resolve issues.
  • What safety features does the machine have?
    The machine includes emergency stop buttons, protective guards, overload protection, and automatic alarms to ensure operator safety.
  • How does screw design influence extrusion stability and film quality
    The screw design affects melting efficiency, pressure build-up, and material mixing. A well-designed screw ensures stable melt flow, reducing defects and improving film uniformity.
  • How does the extruder barrel temperature profile impact film production?
    Temperature zones must be precisely controlled to ensure complete melting without degrading the polymer, affecting output quality and extrusion efficiency.
  • What are common troubleshooting steps for layer delamination issues？
    Check resin compatibility, extrusion temperatures, screw design, and ensure proper adhesion layers or tie resins are used.
  • What innovations are there in extrusion screw technology for blown film?
    Innovations include barrier screws for improved melting, mixing screws for better dispersion, and energy-efficient designs reducing power consumption.
  • What types of plastic films can the blown film machine produce？
    It can produce various plastic films such as PE, PP, PA, EVOH, supporting 7-layer and above co-extrusion structures.
  • What are the advantages of 7-layer and above co-extrusion blown film machines?
    Multi-layer structures offer barrier, moisture resistance, reinforcement, and other functions, enhancing film performance for high-end applications like food packaging.
  • What does after-sales service include？
    Installation and commissioning, technical support, regular maintenance, and spare parts supply to ensure stable operation.
  • Does the equipment support automation and intelligent control?
    Our blown film machines are equipped with advanced PLC and touchscreen control systems, supporting automated operation and data monitoring.
  • Can the equipment achieve automation and intelligent control?
    Our blown film machines are equipped with advanced PLC and touchscreen control systems, supporting automated operation and data monitoring.
