Direct Compression

Smooth surfaces

Commonly used to produce medical inserts

In direct compression molding, a polyethylene insert (or other material) converts rubber or other compounds to a finished or semi-finished part using individual molds.

One advantage is an extremely smooth surface finish obtained with a complete absence of machining marks. In addition, if desired, higher processing pressures are possible because the projected surface area of each individual mold is relatively small compared to the area of large molds used in compression molding.

Direct compression molding has been used for decades to produce various medical inserts. Direct compression was adopted because cutting and milling machinery in the past could not be technologically controlled.

With today’s high-tech options, we have the ability to accurately produce the complicated curves often required to make complex products.

Direct compression technology is high specialized and requires a great deal of planning and design. Consult with a TMI expert today.
