The Expandable Cavity is
maintained under compression during molding (left). As the mold opens, segments are released automatically to the expanded
position (right) and the part is released.

Wide Variety of
Applications
The Expandable
Cavity was developed for molding parts with undercuts such as threads, dimples, and protrusions.
Typical molded parts would include:

Broad Range of Benefits
Simple
Design
The revolutionary design and engineering of the Expandable Cavity
saves steps and solves problems that have complicated molding for years. In addition to simplifying new tooling design, it can
be retrofit to any existing molds.
More Reliable
Complete reliability of the Expandable Cavity is assured, not only by the simplicity of design, but also by the use of superior
materials and proprietary processing techniques. You can count on minimal down time and higher productivity over the long
term. Ther expandable has been field tested over several million cycles.
More Compact
Using the Roehr Expandable Cavity allows you to design more
cavities in each mold. click here for examples.

Speeds Molding
Process
The Expandable
Cavity concept completely eliminates the need for side-action mechanisms and the additional machining steps they require.
Various part ejection methods can be employed.
Speeds Developement
The expandable
Cavity concept simplifies the engineering required to design and manufacture a new cavity. This means that your new
products go into production in less time than was previously possible.
Lowers Developement &
Processing Costs
The Expandable Cavity saves money at every step from initial tooling to processing to
maintenance. Intelligent engineering reduces or eliminates a number of factors that have in the past added complexity and
cost. Items such as complex design details, core slides and required mechanical components, added maintenance and
replacement of high-wear items oftem found in traditional slide action molds are eliminated |
