TECNOMOD VACUUM TRANSFER MOLDING [ MTVT ]
Advantages of the Process
1 - Applicable to you ask with high degree of difficulty (undulations).
2 - The two faces of the piece are finish (flats).
3 - System of Closed Molds, without emission of pollutant: it assists ISO 14000.
4 - It spares specialization of the operator.
5 - Light molds: medium molds don't request crane to move them.
6 - Without closings: the external atmospheric pressure closes the Molds .
7 - Total control of the thickness of the piece point to point.
8 - It allows standardization of the process turning reliable and predictable.
9 - Low cost of Molds, equipments and raw material comparing with other systems of closed molds.
10 - Long useful life and it lowers maintenance they are guaranteed for the epoxy resin used to build the Molds.
11 – Raw material of easy supply as roving and ortoftalic resin can be used in most of the cases.
12 - Requested case: sophisticated raw material as aramid, carbon fiber, and varied resins besides epoxy is allowed.
13 - We can introduce beams of PU and inserted in general.
Process
1.After the cure of the gelcoat, the reinforcement is placed in the female
2. It installs the male for top of the female and connect the vacuum bomb. It opens entrance of the resin after extracting the air of the cavity of the Mold
3. Completion of the cavity. Time of wait for cure of the resin : 8 to 12 minutes
4. The pressure of the seal rubber liberates the male and the piece is removed
