# Advanced thermoplastic injection

In March 2019, a part of Colortec’s technical staff took part in a course delivered in the headquarters of the local organization IBIAE by the Spanish Plastics’ Centre (CEP in Spanish), in order to understand and obtain a 360º vision of the latest injection techniques. Some relevant companies in the plastics sector were present and enhanced the attendees’ perspectives with the experience of their workers. Some important and innovative issues about the injection of thermoplastics were discussed, such as the following topics:

- Contractions, deformations and breaks.
- Post-contraction problems due to inner tensions.
- Pinholes and deformations due to a bad design of the pieces and their computer simulation.
- Alterations in deformations by applying reinforcements (fibreglass).
- Mechanical properties of the pieces according to their level of crystallization and how mould temperature and the thickness of the pieces have an effect in the contraction.
- Design of nerves in order to grant robustness to the piece, instead of flection and torsion.
- Solutions to breaks and location of injection inflows.
- Moldflow simulations.
- Flow index (MFI/MVR) and its relation to mechanical properties.
- Study and optimisation of the parameters of maximum influence in the injection process.

With these and many other training activities, our objective is to keep our technical staff focused on the future and oriented to our customer, in order to offer the best service in our sector.
