About This Product
In the paste extrusion equipment, PTFE fine powder and extrusion aid are mixed, preformed into a cylindrical or cylindrical shape using a preforming machine, extruded into the desired shape using an extruder, and fired in a firing furnace. PTFE molded products such as tubes, wire sheathing, and sheets made by paste extrusion have high heat resistance, chemical resistance, flame retardancy, corrosion resistance, slipperiness, and electrical properties, and are used in automobiles, electrical products, chemical products, etc. Widely used in industries such as pharmaceutical piping and the medical field.
Among these, "porous membrane materials" used in automobile O2 sensor cables, coaxial cables due to advances in communication technology, and various filters have been increasing in recent years as a new field. In the medical field, we also manufacture thin-walled tubes used in catheter liners.
■Device
・Wire coating forming equipment
・Tube extrusion molding equipment
・Sheet extrusion molding equipment
■Main uses
Coaxial cables, automotive O₂ sensor cables, industrial tubes, medical tubes, ePTFE tubes, ePTFE wires, etc.
■Basic process
・1. Blend PTFE fine powder and extrusion aid in a mixer.
・2. Preform into cylindrical/cylindrical shape using preforming machine
・3. Extruded at room temperature and high pressure using a paste extruder
・4. Dry the molded product in a firing furnace → complete by heating to firing temperature (continuous or separate process)
■Electric drive type PTFE paste extrusion equipment
Normally, resin wire coating using the paste extrusion method is approximately 50 microns thin at the most, but Tabata Kikai Kogyo has equipment that can make this even thinner, 30 microns or less. Applications of this ultra-thin walled wire include catheter liners, etc.
Tabata Machine Industry is the first in the world to adopt an electrically driven PTFE paste extrusion device. The electric motor drive and precision drive mechanism enable extrusion molding at a stable speed.
