JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Pinette Emidecau Industries (PEI) has delivered a new thermoplastic stamp forming system to Ibaraki Kogyo, in Japan. This equipment is for stamp forming composite aircraft parts.

The machine is the latest generation of TP stamping systems designed and built by Pinette Emidecau Industries over the past few years. Since PEI is a custom builder of moulding systems, none of these systems are exactly the same and they can be used to form a variety of thermoplastics that include PPS/PEI/PEEK and PEKK. As an example, the systems range from 80 to 1800 metric tons in tonnage. The controls, platen sizes, daylights and strokes are not the same on all of these machines. The controls include recipe storage and complete traceability for quality control and web remote control maintenance.
20 years of experience
The company started building these TP stamping systems more than 20 years ago when a major European supplier of fighter aircraft approached PEI with the technical challenge to build an automated forming system to mould PPS thermoplastic material (for structural wing parts). The material needed to be heated in an IR oven to ensure very uniform heating of the complete blank. The challenge was to meet the requirement of transferring and stamping the parts in less than four seconds.
To meet the quality requirements of the finished parts, the material should not be exposed very long to ambient temperatures outside the IR oven heating zones. To meet this objective, PEI builds the TP machines with a very compact designed system, with the IR oven attached to the forming press. This is also why PEI provides each TP machine with a very-high-speed transfer system with a very high press closing speed.
Quality and flexibility
Because a very high quality material is used, efforts are made to reduce scrap by using custom-shaped blanks. The company has the capability to build custom blank-holding systems that can hold many different blank shapes using several different methods to install the blank holders in the transfer system. PEI has also been a supplier of qualified equipment to many Tier 1 and Tier 2 aircraft parts suppliers worldwide. To work with these aircraft industry suppliers, the company has built a strong, efficient and highly reactive maintenance programme that can provide both service and maintenance contracts worldwide.
With its experience in equipment for the TP industry, the company hopes to continue building many more of these systems, as both Airbus and Boeing are striving to reduce weight in their fleet of aircraft. Accuracy, consistent performance and reliability are the targets of PEI equipment. The company has 25 years of experience in systems for both the aerospace and automotive industries and its employees can meet any forming needs.
