Connecting the TAS to the mould:

Ensuring that the two nose o rings are in place (just the one o ring on older models), wipe some silicone
grease over the o rings to help protect them from wear.
With the spring clip in position on the Locksert connect the Turbo Autosprue™ (TAS) to the mould by
simply pushing the TAS firmly into the Locksert until a positive click is heard as the spring clip locates,
and locks the TAS in the insert.
Once locked in position the TAS nose will be flush with the base of the Locksert and the mould face.
To check that the TAS is correctly locked in place, pull firmly whilst rotating the TAS body.
To remove the TAS from the Locksert simply turn the spring clip through 90º and gently pull on the TAS
body to release the TAS.

Operation:

With the TAS firmly locked into the mould Locksert connect the machine nozzle to the quick release
input connector. Connect the red 4mm start pipe to the 4mm air fitting on the side of the TAS body.
Place the 10mm nylon drain pipe in a vented waste container ensuring that it is firmly fastened in the
container to avoid the pipe becoming dislodged during flushing with solvent and air.

When the machine starts the TAS valve will open and allow free passage of resin mix into the mould. On
completion of the injection the machine will close the TAS and flush the mix-head, injection pipe and the
internal fluid path of the TAS and then deliver the waste solvent to the vented waste container.
The TAS is suitable for use in all orientations - vertical, upside down and horizontal, and exhaustive tests
have proven that the TAS operates and flushes efficiently with a long service life in all positions with all
commonly used thermoset resin systems, whether filled or unfilled.

All tests have been conducted using one of Magnum Venus Plastech’s injection machines fitted with the
SP3 non-pressurised solvent pump system. In conditions of low air pressure (below 5.0 bar) efficient flush
and cleaning may not occur, leaving build up and traces of catalysed resin within the valve, feed pipe and
drain pipe. Ensure therefore that all flushing systems are maintained correctly and operated at the
recommended supply pressure range of 6 - 7 bar.

SAFETY NOTE:

Ensure that relevant Personal Protective Equipment, especially eye protection, is worn when testing or servicing the
Turbo Autosprue.

Note:

 NEVER - Operate TAS without sufficient cleaning/flushing solvent flow.
 ENSURE – The correct cleaning/flushing solvent pressure of at least 6 bar
 IMMEDIATELY - Renew nose outer red silicon seal (3265) if damaged
 DO NOT - Unlock or attempt to remove TAS from the mould:

1. During the injection or flushing operation.

2. Until the resin in the mould has cured.

 ONLY USE - Genuine spare parts from Magnum Venus Plastech.
 RENEW – Locksert clip if damaged or contaminated.
