Attivar adopts the most suitable technology for the production of gaskets and technical items in rubber or silicone: the choice is made after an in-depth analysis of the item, evaluating its geometry, the type of material, the expected production run, the choices regarding finishing processes and any constraints or requirements on the product.
In addition to the primary criterion of end-product performance, Attivar transposes its know-how of materials and production processes into consultancy aimed at optimising production costs and, consequently, the finished product with a focus on process automation.
The raw material (rubber or silicone) is loaded into a chamber and pre-heated; it is then injected through one or more nozzles into the mould, it goes through runners and then, depending on the article and specifications, enters each cavity through a veil, micro-holes or a direct injection.
As with injection moulding, the raw material is loaded into the chamber and pre-heated, but is then injected inside a mould that is not completely closed. The press then completes the clamping and compresses the injected material thus creating the typical circular plate, which is distinctive for injection-compression moulding. The parts produced with this moulding technology are then removed from the circular plate by means of a parting tool. This technology is particularly suitable for geometries with tighter tolerances.
The non-preheated raw material is placed manually or by means of a robotic arm inside the mould; then the machine compresses the material inside the cavities.
The material is placed inside a tray in the mould; the machine closes and the clamping force injects the material into the cavities through micro-holes.
Similar to transfer technology, but the material is preheated in the chamber and then injected into the mould tray, instead of being loaded directly into the tray. The material is then compressed through micro-holes and reaches the mould cavities.
Our tailor-made gaskets and seals can improve the performance and reliability of your product. We offer a wide range of materials and technologies to meet every production requirement.
