TECNOMOD  VACUUM  PRESS  MOLDING   [ PVT ]

 

 Advantages of the Process 

 

1 - High productivity

2 - The two faces of the piece are finish (flats)

3 - System of Closed Molds: without emission of pollutants:  it assists norm ISO 14000

4 - It spares specialization of the operator 

5 -Lights molds:  small molds don't require 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 the Molds, equipment and materials, 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 - It uses raw materials of easy supply and cheap as cut roving and ortoftalic resin

12 - Versatile: the Molds allow to manufacture pieces with sophisticated reinforcements as aramid , carbon fiber and any resin inclusive epoxy

13 - We can introduce beams of  PU and other inserts.

Process

1. After of the cure of the gelcoat, the reinforcement is placed in the female and it clears up the resin, already blended with load and catalyst

2. The male settles above the female and the vacuum bomb is connected

3. Retreat of the air and pressed of the piece. 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.
