Vents and equipment
LA PLASTECNICA vents
Are you tired of vents that don’t work because they don’t allow sufficient air to get into the mould during cooling? Are you tired of repairing blowholes on the flanges? Are you tired of finding steel wool in your finished part?
La Plastecnica vents stay open during cooling to allow air into the mould, preventing warpage and avoiding blowholes on the flanges.
They take the guesswork out of venting: La Plastecnica vents are produced industrially: the results obtained using them are consistent and repeatable.
La Plastecnica vents stay closed during the heating cycle, allowing quicker sintering and a significant reduction of porosity.

Here is the La Plastecnica vent range:
Intellivent
Intellivent was developed to fit into vent tubes common in rotational moulding tools. This vent fits into any tube with an internal diameter of between 18 and 20mm. Intellivent functions in a similar manner to Smartvent.
Supavent
Supavent is made
of a heat-resistant flexible polymer cleverly designed to create a one-way vent. Supavent allows air to go into the mould but does not allow it to escape. This gives better, more consistent mouldings. It speeds up the sintering process and so reduces cycle times. It also reduces porosity and improves surface finish. It gives repeatable results: because Supavent is a manufactured product designed specifically to fit into venting holes in moulds, its performance is consistent. It does not restrict part shrinkage, is easily incorporated into current pressurisation systems, and makes production of rotational mouldings easier. It reduces scrap rate, cycle time and cost per production cycle. Supavent makes blowholes like those on the parting line and around inserts a thing of the past.
Smartvent
Smartvent is ideal for very technical parts with fine kiss-offs, double walls or critical dimensions. Made from a heat-resistant, flexible polymer, Smartvent is a partial one-way vent that slots into the mould’s vent hole. It speeds up the sintering process so shortens cycle times. In addition it reduces porosity and improves surface finish. It gives repeatable results: like its brother Supavent, it is a manufactured product designed specifically to fit into venting holes in moulds, so its performance is consistent. Smartvent does not restrict part shrinkage. It is simple to use and install, and is easily incorporated into current pressurisation systems. It facilitates the production of small to medium-large technical rotational mouldings, reducing scrap rates, cycle times and cost per production cycle. Its use improves surface quality and finish, and makes blowholes like those on the parting line and around inserts a thing of the past. Smartvent provides less pressurisation than Supavent.
LA PLASTECNICA Equipment
Would you like to reduce your cooling time without affecting your product’s quality? Have you ever heard of Supacool or Technovents?
Tests run by rotational moulders show that, using Supacool to spray a water mist inside the molten part to cool it from the inside, you can shorten your cooling cycle by up to 60%.
For small to medium sized products, internal air cooling using a Technovent will significantly reduce cooling time and warpage.
