Design, development and realisation of a compound suitable for the realisation of injection moulding tank caps.
The objective of the design is to create a new material dedicated to the production of tank caps for the automotive sector. The set of specifications that must be observed is very complex, as the compound needs to be compliant with self-extinguishing classification V0, it must not contain halogens and lastly it must not allow the maintenance of tolerances below 0.05 mm post-conditioning in air conditioned room. last but not least, given the massive production volumes, the compound must fulfil strict reference target prices. The same compound was also formulated in a version useful for realising caps and manufactured items that are generally suitable for contact with drinking water in compliance with WRAS certification (Water Regulations Advisory Scheme).
Field of application: Automotive
Materiale: Compound base PBT
Purpose: Design, development and realisation of a compound suitable for the realisation of injection moulding tank caps.
Success factors: Self-extinguishing V0 classification, No Halogens, Shrinking with centesimal tolerances
