Does anyone know about thermoplastic injection molding parts?

In the US we link our customers to Chemical Data Inc (CDI) resin indices, which is now owned by ICIS. We move monthly or quarterly, depending on the amount the index moves

Hi Rodrigo. Some leading producers of rigid injection moulded plastic packaging parts in Europe link the material part of the price to the Platts Index (S&P Global). In this way the risks of material share change in part's price is addressed fairly. Such agreement is especially common for long-term relationships where the deal size is bigger, clients are more experienced in sourcing and the number of clients buying certain part is limited. The Platts Index data is relatively expensive, but representative enough (at least for olefins; probably also other petrochemicals). As a cheaper alternative to it you may perhaps consider indices published by some specialized German plastic magazines. In the plastic packaging industry the price change as a response to material price change is typically not so difficult to pass on to clients. A much bigger challenge is availability of specific material, as already ^Searchfunder member‌ mentioned.
