Requirements in plastics processing
In plastics processing, surface pre-treatment and activation determine adhesion in bonding, printing and painting. Low surface energy and electrostatic charging are the typical hurdles.
Suitable processes
Which process fits best depends on the part, the contamination and the batch size — we advise on a technology-neutral basis. For this industry, the following are particularly relevant:
- Plasma & corona pre-treatment — surface activation for better adhesion (corona also for films and web material)
- CO₂ snow blasting — dry, gentle cleaning of sensitive plastic parts
- Electrostatics & ionisation — discharging and cleaning of electrostatically charged surfaces
Test the process at TeSe
Whether a process meets your industry’s requirements on your actual part is shown by a trial: 1–2 hours of testing free of charge. In-depth feasibility studies: CHF 1’200 per day, 50% creditable against a machine purchase.
