What is the replacement cycle for accessories of ABA blown film machine?

As a key equipment for plastic film production, the normal operation of ABA blown film machine is crucial for production efficiency and quality. However, as the usage time increases, some accessories in the equipment will gradually wear out or age, and need to be replaced regularly to ensure the stability and production efficiency of the equipment. This article will explore in detail the replacement cycle and influencing factors of the main components of the ABA blown film machine, to help users better maintain the equipment.

1. Die Head

The die head is one of the core components of the ABA blown film machine, which directly affects the quality of film forming. The replacement cycle of the mold head is usually long, usually 2-3 years, but the specific time depends on the following factors:

Production materials: When producing highly corrosive or high viscosity materials, the mold head wears out quickly and may need to be replaced more frequently.

Usage frequency: When the equipment operates continuously or under high load, the wear of the mold head accelerates.

Maintenance situation: Regular cleaning and maintenance of the mold head can extend its service life.

2. Screw and Barrel

Screw and barrel are key components for plastic melting and transportation, and their wear directly affects production efficiency and product quality. The replacement cycle is generally 1-2 years, depending on:

Material characteristics: When producing materials containing fillers or reinforcing agents, screws and barrels wear out quickly.

Operating temperature: High temperature operation will accelerate wear.

Cleanliness: Regularly cleaning residual materials can reduce wear and tear.

3. Heating Bands

Heating coils are used to provide the heat required for melting plastic, and their lifespan is generally 1-2 years. The replacement cycle is affected by the following factors:

Operating environment: High temperature and humid environments can shorten the lifespan of the heating coil.

Operating temperature: Long term high temperature operation can cause aging of the heating coil.

Maintenance situation: Regularly check the working status of the heating coil and replace damaged heating coils in a timely manner.

4. Air Ring

The wind ring is used to control the cooling and forming of the film, and its replacement cycle is generally 1-2 years. The influencing factors include:

Production materials: When producing high viscosity or highly corrosive materials, the air ring wears out quickly.

Usage frequency: High load operation will accelerate wear and tear.

Cleaning and maintenance: Regularly cleaning the air ring can reduce blockage and wear.

5. Filter

Filters are used to remove impurities from molten plastics, and their replacement frequency is relatively high, usually 3-6 months. The specific replacement cycle depends on:

Material cleanliness: When using raw materials with high impurities, the filter clogs quickly.

Production volume: High output equipment requires more frequent replacement of filters.

Filter type: Filters made of different materials have different lifetimes.

6. Transmission System

The transmission system includes components such as motors, reducers, and belts, and its replacement cycle is generally 2-3 years. The influencing factors include:

Load situation: High load operation will accelerate the wear of the transmission system.

Maintenance: Regular lubrication and inspection can reduce wear and tear.

Operating environment: High temperature and dusty environments can shorten the lifespan of the transmission system.

7. Pneumatic Components

Pneumatic components such as cylinders, solenoid valves, etc. generally have a replacement cycle of 1-2 years. It depends on:

Usage frequency: Pneumatic components with frequent movements wear out quickly.

Environmental conditions: Damp and dusty environments can accelerate aging.

Maintenance status: Regular inspection and cleaning can extend the lifespan.

8. Electrical Components

The replacement cycle for electrical components such as contactors, relays, etc. is generally 2-3 years. The influencing factors include:

Operating environment: High temperature and humid environments can shorten the lifespan of electrical components.

Load situation: High load operation will accelerate aging.

Maintenance: Regular inspection and cleaning can reduce malfunctions.

9. Cooling System

The cooling system includes water pumps, cooling towers, etc., and its replacement cycle is generally 2-3 years. It depends on:

Water quality: Using hard water or water with high impurities will accelerate the wear and tear of the cooling system.

Usage frequency: High load operation will shorten the lifespan.

Maintenance situation: Regular cleaning and maintenance can extend the service life.

10. Other vulnerable parts

The replacement cycle for vulnerable parts such as sealing rings and bearings is generally 6 months to 1 year. It depends on:

Usage frequency: Components with frequent movements wear out faster.

Environmental conditions: High temperature and corrosive environments can accelerate aging.

Maintenance: Regular inspection and replacement can reduce malfunctions.

The replacement cycle of ABA blown film machine accessories is influenced by various factors, including production materials, frequency of use, operating environment, and maintenance status. Users should develop a reasonable maintenance plan based on actual usage, regularly check the status of key components, and replace worn or aging parts in a timely manner to ensure the stable operation and production efficiency of the equipment. At the same time, choosing high-quality accessories and original spare parts can effectively extend the service life of equipment and reduce maintenance costs.
