Smartvent

Inventive Solutions for Moulding

Smartvent is a radical one-way vent technology that fits perfectly into vent holes to reduce the production of artifacts. Smartvent technology significantly speeds up the sintering process, it reduces porosity to improve the surface finish and ultimately it reduces cycle times. This radical breakthrough removes the need for other packing based solutions that were traditionally used in vent.

The vent is produced from a heat-resistant, flexible polymer. It's unique design features a petalled dome that fits perfectly within the mould and an open-ended mushroom like shape that sits just outside of it. The petals are designed to allow air to enter the mould more efficiently, reducing any artifacts.

Our patented Smartvent technology is particularly easy to use and produces consistent results. It is currently designed to fit 25mm (1”), 13mm (1/2") and 8mm (5/16") vent holes. Because Smartvent is designed to fit perfectly into venting holes, its performance remains consistent throughout the entire production process

 

Why smartvent?

  • Produces small rotational mouldings

  • Reduces scrap rate, cycle time and costs

  • Improves surface quality and finish

  • Solves the part-line blowhole problem

  • Simple to use and easy to install

  • Provides consistent results

  • Doesn't restrict part shrinkage

  • Can use with existing pressurisation systems

Some of the features of our vents are more specifically described in US Patent 11/033969.

FAQ

Smartvent has been designed to fit into an open hole that measures 8, 13, 19 or 25mm in diameter (depending on which size Smartvent you are using) and 4mm to 8mm in depth. In a cast aluminium mould, this simply requires a hole to be drilled through the mould in the appropriate location. In a sheet metal mould, the placement hole may require a collar to provide sufficient depth.

The location of the vent placement hole will be governed by standard vent hole considerations. Smartvent requires a minimum space clearance of 28, 33, 40, 45mm in diameter around the vent and 10mm of space beyond the vent dome in order to function at its best. The vent will perform better if it is located near a wall or some other feature that will provide some protection from the powder movement.

Fit Smartvent by inserting the closed end of the tube through the placement hole from the outside of the mould until the collar butts up against the outer wall of the mould.

The life expectancy of Smartvent may be increased significantly by mounting it in a PTFE (Teflon®) collar.

If you want to use Smartvent in an existing vent tube with an appropriately sized internal diameter please cut the mushroom off the Smartvent. This can then be fitted into the end of the existing vent tube so that the dome extends into the mould.
