Torr provides many of its elastomeric vacuum tools with plates. Some applications are:
- Manufacturing of laminates or sandwich panels, both production
and test articles.
- Compacting and curing of a mold that is set on the plate.
For this, Torr may have to seam or mold a custom diaphragm.
- Table-top compaction
Vacuum bagging tool with molded diaphragm and machined aluminum base for use with customer's mold. Note gas-springs for counterbalancing the lid.
Front closure holds seal in contact with plate during vacuum initiation. Process is 350°F, 85 psi.
Two EVTs with pleated diaphragms to accommodate mold and part shape. A separate
fairing bar assembly fits around the mold to reduce stress on the
diaphragm. Each tool has one vacuum port and one thermocouple connection
A typical table-top tool used for compacting and autoclave curing of various parts.
Tool has high-temp gas-springs to counterbalance the weight of the
top assembly, and front closures to hold the seal in contact with
the plate during vacuum initiation.
Tool with diaphragm bonded in a "loose" configuration so it fits the part
and reduces stress on the rubber. Note overcenter clamps along the
front edge for holding seal in contact with plate during vacuum
initiation. Front closures aren't required but help in situations
where tools might lose vacuum while staged outside the autoclave
or oven and you want to assure reinitiation.
