Secondary Processing
From braid and coil reinforcement through Tip forming, Marker band, Coating, Printing— we finish extruded tubing to the state just before final assembly.

Each process has its own page covering available methods and what to mark on your drawing.
PTFE will not bond to other polymers as-is. A reagent-free etch activates the surface so liners can be reflowed to an outer layer. The effect holds up to 12 months; older liners are recovered with a secondary etch.
Ink will not hold on untreated PEEK. A chemical-free pre-treatment raises surface adhesion so graduations and markings stay put.
A focused high-energy laser conformally removes or adds surface material, changing micro and macro surface behaviour. Conditions are designed per material and the process scales to mass production.
When extrusion, braiding and coating sit with three different suppliers, anything that goes wrong starts with an argument about whose fault it is. Run the whole process with us and there is one place to call and one place that answers for it.
Extruded tubing moves straight to the next line and finishes secondary processing in the same ISO 7 cleanroom. Nothing is packed, shipped or unloaded in between, so there is that much less to contaminate the part or move the dimensions.
No taking delivery of bare tubing, then finding a local finisher and lining up their schedule. It ships with tip forming and printing already done.
Mark the outer diameter at start and end, the transition length, and the end shape (round / flat / angled). Formed length can go up to 70 mm.
Distance from a datum, circumferential angle, hole diameter and count. For standard arrays such as PIG 8-hole or Straight 6-hole, the name alone is enough.
Marker material (Pt-Ir and so on), position and width. For printing, specify graduation spacing, type size and colour and we run it by laser or ink transfer.
Coated section (full length / distal N mm), and the friction coefficient or wet duration you need. If the purpose is PTFE bonding, tell us whether to etch.
Dimensions, material, application. Those three are enough to start. A drawing makes it faster.
