Not enough detail on the formed parts:
Possible causes:
1-Try drilling tiny (1/16 inch) holes in the mold especially in recessed parts where
the vacuum will have a hard time pulling
2-Make sure the vacuum has no leaks and has good suction (check the filter)
3-Heat the plastic a little longer or use thinner plastic
4-Use a vacuum pump in conjunction to the shop vac
Using storage tanks and other vacuum pumps with the machine:
This machine is equipped with 2 suction ports on the left side they do not to be
plugged or covered since they will open only when suction is applied.
Possible options:
1- Use only a shop vac inexpensive and simple with great results for thin gauge
plastics.
2- Use a shop vac and an electric pump ( transition from shop vac to electric
pump is automatic just leave both on) connect the vacuum pump to the small
outlet (Use a shop vac for initial suction then use a vacuum pump that pulls about
26 or more In.Hg. and has a CFM of 2 or higher for secondary high source)
great for tall molds
3- Use only a direct vacuum pump, a simple and efficient way if you have an
electric pump that is 4 CFM ( cubic feet per minute ) and it pulls 25 In.Hg. or
more . Connect it directly to the small brass outlet.
4- If using a storage tank we recommend connecting it directly to the larger
outlet, you can still use a vacuum pump in conjunction and attach it to the smaller
brass outlet. Transition from storage tank to the vacuum pump is automatic just
have the electric pump running before using the storage tank.
