Press Tooling & Components

In 2015, owing to continued aerospace customer demand, we further broadened our composite manufacturing capabilities with the procurement of our first composite press.

Maintaining our continual investment strategy approach we purchased a new, high specification composite press (Langzauner Perfect Press). This gives us the capability to supply press tooling components up to 600mm x 800mm.

Langzauner Composite Press Capabilities:
  • Maximum Temperature 250°C centigrade (oil heated platens)
  • 1300 kN Pressure capability
  • Pressure, temperature and ram displacement can all be independently controlled
  • Servo driven hydraulics (maximising energy efficiency)
  • Fully programmable at the work station – for new parts/programmes
  • Integrated sliding loading table
  • Full digital cure traceability data logging

In 2016, once again owing to increasing aerospace demand for press tooling components, a second Langzauner press was purchased. This further underpinned our machinery duplication approach. Should we suffer equipment failure we can switch manufacturing to the duplicate machinery thereby, minimising/eliminating disruption.

For simple press tooling components such as flat sheet processing and development projects we also have a third, more basic composite press on-site. This further helps maximise the availability of our larger composite presses for more complex press moulding processes.

Our composite presses are utilised to produce complex aerospace composite press tooling components for highly demanding OEM customers. The composite press moulding process enables faster cycle times which is better suited to volume production.

We have a dedicated production unit for manufacturing pressed components. Our modern facility is fully equipped with a dedicated pre-forming room and storage facilities for kitted prepreg and preforms.

Curing times are typically between 5 – 60 minutes dependent upon resin system/material requirements. We work closely with our material suppliers to ensure we remain at the forefront of composite press prepreg manufacturing. We can also offer “snap cure” prepregs, requiring very short press cure cycles.

Advantages of Pressing:
  • Volume production of structural components where applicable using multi-impression tooling
  • Double “A” surface finish
  • Short cure cycle (5-60 mins) versus autoclave curing (4-12 hrs)
  • Minimised consumable materials (no bagging, breather etc).
  • Fully automated pressing cycle ensures uniform performance every time.
  • Fast turnaround, minimised trimming and fitting – often simple de-burring dependent upon complexity.
  • Multi-stage/phase curing capabilities (insertion of specialist cores)
Project Suitability Considerations:
  • Typically more durable (press moulds machined from aluminium or steel)
  • High volume manufacturing (not suited to low volume/prototyping)
  • Draft angles need careful consideration
