Pastenextruder

The paste extruder from Keicher Engineering AG enables batch production of PTFE products such as thin-walled hoses, thick pipes (liners), wire insulation, and unsintered PTFE tapes. A mixture of emulsified PTFE powder and organic lubricants is pressed into so-called preforms. These preforms are subsequently extruded through a conical die, dried, and sintered.
