COMPRESSION MOLDING

Compression Molding & Sheet Molding Compounds

Compression molded parts are key to many aircraft applications in which strength, reduced weight and cost are a factor. Compression molding (or compression moulding–we’ll use both spellings interchangeably here) applies temperature and pressure to form, cure, and bond aerospace components. Compression molding introduces a resin, compound or rubber to a fabric, impregnating it in order to create a bonded compression material to perform to specific strength and force standards.

Sheet molding compounds, or materials used in compression molding can utilize thermoplastic compression molding compounds such as Nylon, PEEK, PEI and PPS. Or they can be thermoset such as  BMI, cyanate ester, and epoxy.

Compression Molding Applications

Compression moulding applications can include a variety of aerospace components such as composite fan blades, brackets, face sheets, covers, clips, structural and semi-structural parts, and many more.

Advantages of Compression Moulding

Some of the advantages for aerospace applications are:

  • Specific strength for specific purposes
  • Lighter weight
  • Less need for machining/tooling
  • Higher performance at a lower cost
  • Reduced part labor
  • Increased control over dimension and stability
  • Can sometimes combine simple parts into one more intricate component

Overview: How it Works

In general a two-sided mold is used, a cavity part of the mold which houses the compression molding compound and the plunger portion which is aligned to fit inside the cavity part. These two parts are squeezed together under heat and pressure tailored to the unique needs of the aerospace part being manufactured. The pressed part is then cooled and either sanded, filed, frozen, or tumbled to remove any excess or “flash” material.
