The PTFE Hydraulic Pressing Machine, also called PTFE tape extrusion machine,  is a high-performance special machine specifically designed for compressing pre-baked PTFE powder into a desired shape.

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

Key features include:

Two-Step Extrusion/Pressing 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.

Automatic Stop Function:
Equipped with some limit switches, the press automatically halts when the pre-set limit is reached, enhancing safety and minimizing waste.

In summary, the PTFE tape extrusion machine is an advanced, efficient, and highly reliable machine designed for the precise extrusion of PTFE powder materials.

Its constant pressure control, intelligent plunger adjustment, and user-friendly features make it an essential tool for PTFE thread seal tape production line.
