About cpp casting film machine

Types of CPP Casting Film Machines

CPP casting film machines are manufactured using a variety of methods and technologies. Here are some ways to categorize them:

  • Based on Process Technique

    Extrusion Blown Film Machine for CPP is one of the common types. It extrudes heated polymer from a die into a thin tube. The tube is then caught and blown into a large bubble. The bubble cools and solidifies, and it's flattened and cut into rolls.

  • Based on Automation Technology

    Automatic CPP Film Extrusion Machines are equipped with automated systems for controlling the extrusion and cooling processes, reducing the need for manual supervision. On the contrary, Manual CPP Casting Film Machines require manual operation and oversight for film production.

  • Based on Film Application

    Single-layer CPP film extrusion machines produce simple films. Their production lines are short and efficient and take less time to train on how to use them. Multi-layer CPP casting film machines, however, are more complex, and their layers have different features.

    Some Film Machine Extruders are designed to produce Films meant for packaging. Others may be tailored for industrial Films, while some are for agricultural use. Packaging Extrusion Machines have a simple production line. Their skills are not as advanced as those of the Packaging machines. They mostly produce single-layer films meant for packaging.

  • Based on Production Speed

    Fast CPP Film Extrusion Machines offer high production speeds, enabling rapid film production. Standard-speed CPP film extrusion machines operate at regular production speeds, providing a balance between speed and film quality.

Specifications and maintenance of CPP casting film machines

Specifications for CPP film machines may vary, depending on the manufacturer and model. Some typical ones include the machine's capacity, which is usually given in terms of the output, the film's thickness, and the processing speed. The capacity can range from 200 to 400 kgs per day. The thickness can range anywhere between 0.5 to 2.5 microns. The processing speed can be anything between 150 to 300 meters per minute.

Other common specifications are the film width, heating system, die head type, the chill roll temperature, the drive system, and the motor power. The film width can range from 1000 to 2000 mm. The heating system can have up to 8 heating zones for better temperature control. The die head type can be an R-type die head, M-type die head, or T-type die head, with the R-type being the fastest. The chill roll temperature usually ranges from -5° to 10° C. The drive system is usually a geared motor or a universal motor. The motor power consumes approximately between 5 to 15 kW.

Maintenance

  • Regular lubrication: Regular greasing and lubrication of the components will help to keep them operating for longer without wearing out. This will extend their life span, as it will reduce their dependency on the constant usage.
  • Cleaning: Cleaning the machine often from film residues, dust, and other contaminants will keep the casting machine in good condition. Neglecting the cleaning will result in blockages and reducing its efficiency.
  • Replace and repair: With time and use, certain parts may wear out and affect the film's quality. These include the rollers, films, heating elements, and blades. The function and performance of the casting film machine will decline. So, the parts must be replaced or repaired as needed.
  • Calibrate: Machines' settings may shift over time due to regular use. So, they must be recalibrated periodically to maintain the accuracy of the film's thickness and the efficiency of the production line.
  • Dust extraction: Dust must be extracted from the machine and surrounding areas. It is important because the buildup of dust can become a major fire hazard and pose health risks to operators.
  • Cooling system: The casting film machine requires a proper cooling system. This is critical for its optimum performance because the machine generates a lot of heat during the process of casting films. Ensuring that the machine has a working and efficient cooling system will prevent it from overheating and damaging it.

How to choose a CPP casting film machine

When selecting a CPP casting film machine, choosing one that meets manufacturing needs and requirements is essential. Several features, such as the film width, output capacity, die system and type of control system, should be considered.

  • Film width: The film width is an essential feature to consider since it determines the machine's casting area. The required film width will depend on the application and product specifications. Ultimately, it will impact production efficiency.
  • Output capacity: The output capacity of a CPP film machine indicates the production volume of films the device can manufacture within an hour. It is typically presented in kilograms per hour (kg/h). A higher output capacity film machine will enable greater production efficiency, therefore, meeting higher demands.
  • Die system: Buyers have to decide whether they want a single die or a multi-die system. A single-die system is more suitable for those who want to produce films with different types of thicknesses. Meanwhile, a multi-die system is more suitable for mass production of films with consistent thicknesses.
  • Control system: The control system determines the degree of automation, precision, and ease of operation of the film machine. Buyers can choose between a manual, semi-automatic or fully automatic control system. In addition to that, they can also choose between a PLC-based digital touch screen, computer-based controls, and other different types of control systems. Consider the desired control features, accessibility, and simplicity before making a choice.
