Composite Solutions: Aerospace & Defense

What sets Unitech apart is the breadth of our manufacturing capabilities. While many aerospace composites companies can provide Hand Laid Up manufacturing, Unitech supplements this capability by providing Resin Transfer Molding, Compression Molding and Filament Winding manufacturing. This coupled with our tight tolerance composite CNC machining allows us to manufacture and assemble almost any aerospace composite part.

Total Manufacturing Space

  • 115,00 ft2

Clean Rooms

Unitech uses CCA clean rooms for all composite layup. All rooms are Humidity, Temperature and Positive Pressure controlled and all technicians wear Personal Protection Equipment to prevent FOD transfer.

  • 10 Clean rooms with over 16,000 ft2 of space

Autoclave Curing

Unitech Composites has 4 certified autoclaves with state of the art controls including heat up rate, dwell times, pressurization and cooling.

  • 5’ x 10’
  • 11’ x 25’
  • 6’ x 8.5’
  • 15 x 31’

Oven Curing

  • Unitech Composites has 7 ovens ranging from 2’ x 2’ x 2’ to 7’ x 8’ x 8.5’

Hand Lay-Up

Unitech has extensive experience manufacturing composite parts with prepreg hand lay up techniques. UCI’s continual investment in Ply Cutters, Clean Rooms, Autoclaves, Laser Projection Systems, as well as training and retaining our dedicated technicians is what allows Unitech to provide a range of low through high complexity composite parts which meet and exceed our customer expectations.

Filament Winding

Unitech has 3 automated Filament Winding machines that are used to fabricate composite parts requiring continuous filament laminates. These machines, helical and polar winders, are crucial to several components associated with the main rotor hub system for the MD Helicopters 902 program.

These machines are used to create custom layup solutions that can maximize strength to weight in structural applications as well as continuous tubular parts. Parts range in size from the smallest, a few square inches and a single layer thick, to sections of a helicopter Rotor Blade.

Filament Winding

  • Max length 18’
  • Max diameter 38”
  • 4 spools

1 Polar Winder

  • Max length 18’ 4’
  • 1 spool

Resin Transfer Molding

RTM manufacturing is a differentiator for our Composites manufacturing. Unitech can provide turnkey solutions including tooling design through part manufacturing. The key is designing the tool to ensure even resin flow and temperature cure. We manufacture everything from engine composite ducts to a complete Rudder section for the G280 business jet that requires a tool weighing 38,000 lbs.

  • 7 Oil Heater RTM Injection Stations
  • 2 Water Heater RTM Injection Stations

Compression Molding

Our Compression Molding cell is primarily used to mold small components for our Fighter Helmet Visor product line. Current capability allows us to expand the cell for larger product requirements and programs.

  • 30 Ton molding press
  • 2’ x 2’ Heated Platens
  • Fully automated programmable cycles

Composite CNC

Unitech companies have some of the best composite CNC capabilities in industry. We have different machines and sizes in order to meet the requirements of the smallest airframe bracket to large F-35 surface seals. We have 12,000 ft2 of space dedicated to CNC machining and routing.

Holding tight CNC tolerances is a specialty at Unitech. This is accomplished through the quality of the machines we use, set up and installation of the equipment and the expertise in our CNC programmers and operators.

  • 2 – 3 axis routers
  • 3 – 4 axis CNC
  • 7 – 5 axis CNC largest 25’ x 10’
  • True position and Thickness = 0.003”, Profile = 0.007”

Laser Projection Systems

Unitech uses state-of-the-art Virtek LPS-7, LPS-10 and LAP Laser Projection Systems to facilitate and guide in hand layup of composite parts. Virtek’s LPS-10 is a 3D laser system designed to increase productivity, ensure placement accuracy and helps control the process for repeatability.

  • 9 Laser Projection Systems for ply layup

Quality / Inspection

Both of our locations have NDI/NDT capability as well as Digital Inspection Devices.

  • 3 NDI Ultrasonic Inspection Tanks
    • Largest 18.5’ x 6’
  • 1 – CMM
  • 5 - 6 axis FARO Arms
  • 2 - 7 axis CMM Romer Arms

Other Equipment

  • 3 automated ply cutters
  • 3 Platen Presses
  • Paint booths - max size 28’ x 14’ x 9’
  • 3D additive printing
  • Eutectic Salt manufacturing
