Semi-finished products
Internal production of plates, rods, tubes and billets
PTFE, fluoropolymers and other high-performance plastics can be compression-moulded or extruded in different shapes. Vanéflon produces rods, tubes, sheets and near-net shapes in a wide variety of materials and sizes.
- Large range of tools and moulds to deliver customised products for your specific needs, as close as possible to your end dimensions
- High flexibility with an extended and automated production facility allowing for small to large production series
- Large inventory of >100 grades of fluoropolymers and compounds available
- Hot and cold compression moulding for small series in fluoropolymers
- High quality with full traceability and certification
- Post-treatment such as tempering , grinding, rounding and cutting options available
Aside from standard sheets, rods & tubes of which sufficient stock is typically available, Vanéflon is especially known for its near-net shapes and flexibility to produce smaller batches in fluoropolymer compounds.
SHEETS
Vanéflon produces standard sheets in different fluoroplastics such as PTFE (incl. all compounds), PCTFE, PFA, FEP and ETFE as well as other high-performance materials such as PEEK, POM, PET, etc.
Thickness and dimensions vary depending on the material used. Vanéflon uses different techniques to deliver products to your specific requirements such as compression moulding, hot moulding, etc.
Vanéflon is also able to saw/cut your sheets to your desired dimensions in order to meet your requirements as closely as possible.
RODS
Vanéflon produces standard rods in different fluoroplastics such as PTFE, PCTFE, PFA, FEP and ETFE as well as other high-performance materials such as PEEK, POM, PET, etc.
Aside from typical extrusion rods, Vanéflon can produce rods using cold or hot compression moulding both vertically and horizontally pressed. The latter has a major advantage as it offers constant material quality and uniform ultra-low residual stress due to constant pressure monitoring over the entire length.
Horizontal moulding makes the rods perfectly suited for high-precision machined parts while offering excellent chemical and mechanical characteristics. They allow for tight and stable tolerances while significantly reducing machining scrap.
TUBES AND BILLETS
Vanéflon produces tubes and billets in different fluoroplastics such as PTFE (incl. all compounds), PCTFE, PFA, FEP and ETFE as well as other high-performance materials such as PEEK, POM, PET, etc.
Aside from typical extrusion tubes, Vanéflon can produce billets using cold or hot compression moulding, both vertically pressed.
Vanéflon has hundreds of moulds available to press billets as close to final dimensions as possible. This allows for considerable flexibility in size and length, always with tight tolerances on both inside and outside diameters.
If needed, Vanéflon can produce its own moulds in the short term to be able to offer exactly what you are looking for.
NEAR-NET SHAPES
Near-net shaping is an industrial production technique ensuring the compression-moulded item is produced very close to its final shape, reducing machining time and material consumption. As such, this technique not only leads to cost savings, but also increases productivity, reduces lead times and improves the sustainability of the product.
Vanéflon can use this technique with all fluoropolymers like PTFE, modified PTFE and all PTFE compounds. The degree of “finished form” can be decided together with the customer.
FLUOROPOLYMER COMPOUNDS
Thanks to our large set of tools, grades and presses we can compression mould any possible fluoropolymer compound in every possible semi-finished form (sheet, rod, tube, etc.). This is particularly interesting for smaller series, test batches, tubes with dimensions close to final part dimensions or where short lead times are needed.
The most common PTFE compounds include carbon, graphite, bronze, glass, stainless steel, aromatic esters, etc. in various different percentages or combinations. Vanéflon can also produce several compounds in different grades in modified PTFE, PFA, PCTFE, PEEK, ETFE, etc. Vanéflon has over 100 different fluoropolymer compounds in stock and can typically deliver customised products within 3 weeks.
Our semi-finished products are as such especially useful for specific sealing applications in challenging production environments.
