Vacuum Fixturing
Creation of vacuum fixtures for CNC trimming of formed parts is quick and economical with the new HYVAC material from CGP. The material is also used to create simple go/no-go test fixtures when checking formed parts for size/fit requirements.
Is provided as a simple three-part kit consisting of resin, catalyst and fiber reinforced spheres. Resin and catalyst are combined and poured into a supplied mixing bag along with the spheres. Shake to coat the spheres with the adhesive, then pour the contents into a formed part. Anchor blocks to attach the fixture when cured are pushed directly in to the mixture.
The system may be operated from a basic shop vacuum system or connected directly to a high volume vacuum line on automated trimming machines. (CGP recommends a minimum 2.0” diameter vacuum line with unrestricted flow for optimal performance.)
Sections that require large cutouts from interior portions of the part may be blocked off with a thin layer of urethane or other non-porous filler adhesive.
Following a room temperature or oven cure, the system provides a stiff and highly effective custom fixture that may be installed on an automated router table or manual cutting system.
