Brimar uses drape forming (also called oven forming) when a plastic part requires a more general, or gradual bend than heat bending processes can provide.  It works well on both large and small parts.

A male mold is produced with the desired curve for item to be formed.  Thinner material may be placed in the mold while it is cold and both the mold and material are heated to forming temperature.  Once the material and mold have been returned to room temperature, the material will retain the shape of the mold. 

If thicker material is required, it is heated to forming temperature, then placed in a mold and clamped in place.  After is has cooled, it retains the shape of the mold.
