TECNOLOGIE OPEN SOURCE PER INDUSTRIA 4.0 - Code_Aster & Injection MoldingAndrea Pisa
Nello stampaggio ad iniezione dei polimeri (injection molding) la termica dello stampo riveste un ruolo fondamentale sulla qualità del pezzo prodotto. Lo stampo, oltre a conferire la forma, è progettato con un circuito di condizionamento utile a smaltire omogeneamente il calore necessario a far solidificare il pezzo mantenendo allo stesso tempo una temperatura superficiale sufficientemente alta da permettere lo scorrimento del polimero nella cavità. Durante l’avvio produzione lo stampo passa da temperatura ambiente alle condizioni di regime attraverso un transitorio che dura un certo numero di cicli di stampaggio non noto a priori, normalmente i pezzi prodotti in questa fase vengono scartati in quanto non conformi. In questo lavoro Code_Aster è stato utilizzato per ottimizzare un avvio produzione simulando l’evoluzione termica derivante da una serie di cicli di stampaggio a partire da una condizione di avvio definita. Lo script di simulazione è stato inoltre progettato per interfacciare Code_Aster con un file xml contenente i parametri con cui l’operatore può facilmente modificare le condizioni del ciclo produttivo (iniezione, raffreddamento ed estrazione), i parametri del circuito di condizionamento e tutte le condizioni geometriche al contorno. Il responsabile produzione, utilizzando questo script Code_Aster, sarà così in grado di individuare preventivamente i settaggi macchina migliori per ridurre i cicli necessari al raggiungimento della condizione stazionaria, risparmiando tempo e risorse. Lo sviluppo dello script prevederà l’accoppiamento indiretto delle superfici di condizionamento con una simulazione CFD eseguita su openFoam al fine di migliorare l’accuratezza dei risultati.

Electrochemical machining (ECM) is a process that removes material from a conductive workpiece using electrical current. In ECM, the workpiece acts as an anode in an electrolyte bath, and material is removed from the workpiece and transported to a cathode tool. ECM can machine complex shapes in a single pass with no cutting forces and leaves the workpiece stress-free. Key factors that affect the ECM process include electrolyte composition and flow, voltage, feed rate, and current density between the tool and workpiece. ECM is used for aerospace, medical, and automotive applications where other machining methods cannot produce the required geometry or precision.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

porosity)
– No thermal shrinking
– No micro/macro solute segregation
• Casting speeds: A→1.15A→1.20A→…
• Various cooling setups
Numerical Modeling Department 20
16. Numerical problems
• The simulation of casting is a very difficult
numerical problem. The fast transition from the
liquidus to the solidus temperature (energy
release-latent heat, viscosity transition from liquid
to solid) makes the equations very “stiff”: small
changes lead to instabilities and to the destruction
of the solidification front
• It is very difficult to find a convergent solution
• Unless one finds a convergent solution, one must
not trust the small details of the final result
Numerical Modeling Department 21
17. Numerical problems
• We tried many different numerical
approaches
• We were able to obtain convergent
solutions that we can trust!
Numerical Modeling Department 22
27. Primary Conclusions

not allow the increase of productivity
• Setup asymmetries
Fix
Numerical Modeling Department 32
28. Revisited problem 2015
• Basic factors related with productivity:
– Depth/Geometry of molten metal in mould
Modifications
Speed increase 15-20% !
Need to go even faster!
• Setup asymmetries
Fixed !
Numerical Modeling Department 33
29. Preliminary results 2015
• The shape of the solidification front
consists of 3 parts:
1. The growing solidification front in the mold
2. An almost cylindrical front in the air gap
region below the mold
3. A V-shaped final solidification front in the
water curtain region
Numerical Modeling Department 34
38. Conclusions
• The shape of the central solidification front
depends only on the casting speed
• The improvement IS NOT due to changes in
the shape of the front at the center
• Increased metalostatic pressure compensates
for solidification shrinkage porosity
• Thermo-mechanical investigation of cooling
beyond solidification
Numerical Modeling Department 44
39. Conclusions
• Increasing the height of the air gap leads
to secondary problems due to very slow
solidification rates and/or remelting at
intermediate radii
• Future trials:
– Modified cooling
– Thermo-mechanical investigation with ANSYS
