Processing Options
Most TEPEX® products can be cut with a straightforward sheet slicer. Depending on the type and quantity of material, the following cutting methods can be used for more complicated cuts:
- Slicer: only for straight cuts, standard method for sheets
- Die-cutting with forged knife blade: rapid method; low investment for thin sheets (<1.0 mm)
- Die-cutting with shear edge tools: for thick sheets, economical for large production runs
- Water jet cutting: suitable for small to medium production runs; less so for aramid-reinforced material, as high level of water absorption
- Laser cutting: somewhat faster than water jet cutting, less suitable for carbon
- Ultrasonic cutting: very suitable for aramid-reinforced material and for thinner sheets (< 0,5 mm)
Trimming
To some extent the same methods as for pre-cutting are used for cutting the formed products. The most suitable method depends on the material, geometry and volume.
- Die-cutting with forged blade: rapid method; low investment for thin sheets (<1.0 mm); high investment for thick sheets; economical for large production runs
- Matched die-cutting: also suitable for thicker components where metal tools are used; high investment required for thick sheets; economical for large production runs
- Ribbon saw: fast, economical, only for relatively straightforward contours
- Water jet cutting: suitable for small production runs; less so for aramid-reinforced material, as high level of water absorption
- Laser cutting: somewhat faster than water jet cutting, less suitable for carbon
- Ultrasonic cutting: very suitable for aramid-reinforced material; for thinner sheets
- Milling: fast, suitable for most applications, less suitable for very thin materials (<0.5 mm)

Bonding
A wide range of adhesives are available for all TEPEX® types. We will gladly advise you on the choice of the correct system.
Welding
Thanks to the weldability of the thermoplastic matrix, it is possible to weld TEPEX®. If the polymer system of the partners to be joined provides a match, the following methods which are suitable for volume production and have been widely tested in plastics technology may be used:
- Ultrasonic welding
- Vibration welding
- Induction welding
- Resistance welding
- Laser welding
Painting
Although very good surface finishes can already be obtained with TEPEX® in conjunction with suitable mould technology, in some cases further finishing of the components is desired. Most TEPEX® types can be readily painted; prior surface treatment may occasionally be necessary.
