Alu-V® (and Alu-V+ for greater size parts manufacturing) is a forced ventilation system developed by AZTERLAN to generate low-medium vacuum in injected aluminum molds in order to avoid defects in components manufactured using HPDC technology.
It reduces porosity and improves the soundness of manufactured components, favoring, in particular, the creation of parts with thin walls, the development of structural components and ensuring the weldability of injected parts.
- Evacuation of gases trapped in molds.
- Elimination of any impurity or residue after the lubrication process.
- Improved mold filling and component soundness.
Advantages
- Reduction of the porosity of the injected components.
- Manufacture of parts with thin walls.
- Improvement of the mechanical properties of cast components.
- Assurance of the consistency of mold filling.
- Improved process stability.
- Harmonization of the variability of the HPDC process (lubrication, pollution, mold temperatures,...).
- Improved cycle time by reducing the lubrication process.
- Reduction of the speeds of the second phase.
- Avoidance of die soldering and improvement of the life of the mold.
- Complete monitoring of the injection cell, with control of the most critical variables of the process.
- Integration of chill vents with a thickness of 1.5mm, with a life of 2.5 times greater (200,000 injections) and expulsion forces 35% less (<350N).
- Robust equipment designed for industrial application at aluminium HPDC foundries.
- Low maintenance.
- Self-cleanliness phase.
- Intuitive and easy-to-use display for different levels of knowledge and users.
- Advanced monitoring of the main process parameters.
- Easy to understanding the results generated by the system.
- Quick and reliable data collection.
- Straightforward programming synchronised with the piston movement.
- Detect air leakages in molds to prevent defective components.
- Mold adaptation study.
- Integration of the team in the client's production process.
- Staff training.
- Maintenance and calibration service.
- Technical support.

The Alu-V® and Alu-V+® systems offer all the vacuum pressure monitoring data synchronized with the casting curves.
This is highly relevant information that can help detect pressure leaks in the molds and, with this, prevent manufacturing defects due to poor mold closure.
“The Foundry of the Future is that of connected processes that is able to take advantage of the knowledge generated inside the company at the same time that it keeps learning from its manufacturing and market experience.
Along with a deep knowledge of metallurgy, Industry 4.0 technologies, advanced data management systems and machine learning technologies have landed in this industry to transform the way castings are conceived”.
