Utilizing a two-step extrusion process, this machine ensures precise and efficient production, making it ideal for industrial applications requiring high-quality PTFE products. It is key one of thread seal tape making machines.

Key features include:

Two-Step Extrusion Process:

  • Pre-Extrusion: The raw material is pre-compressed to form a compact structure.
  • Final Extrusion: The material is then extruded into a rope-like shape, which is stored in an insulated container to maintain its properties.

Constant Pressure Control:
By adjusting the oil flow through a regulating valve, the press achieves a stable and constant extrusion pressure. This ensures uniformity and reliability in the final product.

Variable Plunger Speed:
The plunger’s descent speed is intelligently adjusted throughout the process:

  • At the start, the plunger moves faster as the raw material contains a higher amount of extrusion aid, reducing resistance.
  • As the extrusion aid is depleted and the material hardens, the resistance increases, causing the plunger speed to decrease naturally.

User-Friendly Operation:
The press is easy to operate, with minimal manual intervention required. The constant pressure mechanism and variable plunger speed ensure smooth and consistent performance.

Continuous Production Capability:
Designed for industrial-scale production, the machine supports continuous operation, improving efficiency and productivity.

Canlender Machine

Calender machine are mostly two-roll calenders, where the two rolls rotate at the same speed but in opposite directions, causing the material to be compressed and thinned without generating shear stress. The key technical parameters of the calender include roll diameter, roundness, width, adjustable roll gap range, variable speed range, and heating method.

The surface of the rolls must be smooth and chrome-plated, polished to a mirror-like finish. The roll diameter should be no less than 30 cm. The heating methods can include hot water, steam, electric heating, or infrared heating. The lower roll of the calender is usually fixed, and to ensure uniform thickness of the raw material sheet, the surface of the lower roll is typically machined into an arc shape with an edge thickness error of approximately 3%.

The upper roll is adjusted by a pressing mechanism that moves it up and down to regulate the roll gap. The rolls are supported by ball bearings to ensure stable and efficient operation.

The width of calendered film is not only related to the diameter and width of the parison and the width of the calender roll, but more importantly, it is also related to the diameter of the calender roll. The larger the width of the calender roll, the larger the diameter of the calender roll is required. If you need to calender 200mm wide film, you need to calender in the diameter of 150mm, the width of 300mm calender rollers for calendering. Calendering roller barrel can be heated by 50 ~ 80 ℃ hot water to facilitate calendering, calendering roller speed can be taken 1.5 ~ 4.0 m / min. Appropriate increase in calendering roller speed and temperature, can expand a little calendering film width. The thinnest thickness of calendering film is 50um.
