Spin casting process with 3D-resin prototypes | Processo di spin casting con prototipi in resina 3D

In this video we show the various steps in the creation of the mould and the surface finishing of the objects.
SPIN-CASTING PROCESS: from the development of the prototypes to the creation of the objects
Creation of the prototypes in 3D (light-curing DLP-SLA resin)
Creation of the mould with silicone rubber
Spin casting with zamak
VIBROFINISHING PROCESS: from rough to finished and polished objects
Three vibrofinishing cycles: deburring, smoothing and polishing with abrasive and non-abrasive granules and compounds
A drying cycle with heated vegetal granules
The processes applied afterwards are the following: plating, galvanizing, electroforming, burnishing, cataphoresis, etc.

In questo video vengono mostrati i vari passaggi per la creazione dello stampo e per la finitura superficiale degli oggetti.
PROCESSO DI SPIN CASTING: dallo sviluppo dei prototipi alla creazione degli oggetti
Creazione dei prototipi in 3D (resina fotopolimerizzante DLP-SLA)
Creazione dello stampo con gomma siliconica
Colata centrifuga con zama
PROCESSO DI VIBROFINITURA: Da oggetti grezzi a finiti e lucidati
Tre cicli di vibrofinitura: sbavatura, levigatura e lucidatura con granuli e composti abrasivi e non
Un ciclo di asciugatura con granulato vegetale riscaldato
I processi applicabili successivamente sono i seguenti:
placcatura, galvanizzazione, elettroformatura, brunitura, cataforesi, ecc.

انها افضل ماكينات عملت عليها . شكرا للسيد /اندريه لقد دربني جيدا..❤

Qué bueno están!

Most impressive, grazie for the insight! Does zamak allow details under 0.5 millimetres in a spin casting and do you require higher RPM for that?

[@nicemspa3109]

Hi! It's not possible to make objects less than 1 mm thick. You can create details such as the details of a miniature's face, but they must be very small areas.

[@isekaiexpress9450]

@@nicemspa3109 Thank you for the reply! Is it possible to create such details (as ventilation grilles or miniature lettering) on surfaces, that provide stability?

[@nicemspa3109]

@@isekaiexpress9450 The writing, in addition to the thickness of the object, creates stability as the space available for the metal to slide is increased. The grid depends on its size and shape. There is always a need to vent air from the center of the grill.

@@nicemspa3109 thank you for the reply! During my internship at a major railway model manufacturer in Germany, i was told that the high pressure of 300 KN in die casting is necessary of the need to overcome the viscosity of molten zamak to fill in the EDM-etched stainless steel moulds and to prevent microcavities that may promote zinc rot. I thought it was a bit overboard and such quality could also be achieved with your spin casting machines.

[@kevinwilson2426]

Which silicone rubber is this? We use a RTV silicone rubber but never seen this silicone before. Is it a heat set?

[@nicemspa3109]

Our silicone rubbers don’t work with room temperature hardening like the RTV silicones. Our silicone rubbers need to be vulcanized in a press, with heat and pressure. This silicone rubbers are much more mechanical and heat-resistant. We sell as well RTV silicones, but are different from the one shown in this video

Which 3D printer are you using in this video? Thanks

[@nicemspa3109]

the 3d-printer shown in this video is "Anycubic mono 4k" - but isn't available. Our technicians now are using "phrozen mighty 8k". They told me that is very valid.

[@cucciolootto]

please can you help me, I can't remove the porosity in the 35MM pitch round rings, I inject the top right and the small air below, letting it come out of the rubber, but the porosity and holes always remain, do you have an effective remedy

[@prasadk4477]

can the silicon rubber die handle molten silver

[@nicemspa3109]

It is not possible to cast the silver alloy directly in contact with the silicone rubber. The high temperature of the alloy would immediately burn the silicone mould. You should proceed with the investment casting process.

White colour liquid you dip the resin what is that liquid name

[@nicemspa3109]

Hi! It's our releaser agent, we call it Releaser Agent type "J", specific for resin prototypes

[@ashishshegaonkar9003]

What is plung the prototype ?

[@nicemspa3109]

Hi! We mean to immerse well in our releaser. Releaser J is a special liquid that grants that the prototypes won't stick into the mould

[@ALIBABAEXCHANGE]

You moved the samples in a white substance. What is the name and brand of that substance? I would be very happy if you answer

[@nicemspa3109]

Hi, it's a special release agent produced by us.

Hi Georges, sure! Where your company is located?

non c'è nemmeno più bisogno di fare il taglio a triangolo per ritrovare il sopra con il sotto. basta prendere un pennarello indelebile e farci il segno 😁

[@nicemspa3109]

vero! Il risultato è comunque lo stesso :-)

[@cucciolootto]

poi vedo che anche voi, ancora nel 2023 date il talco con il pennello. il miglior modo di dare il talco uniforme e sprecando meno talco è mettere il talco dentro un sacchetto di cotone . dal 1993 io uso il sacchetto

Lo sappiamo, certi tecnicismi li spieghiamo durante il training..

rimango sbalordito, per fare il segno del centratore, basta mettere il funghetto in mezzo, e mettere la staffa superiore dentro e fai il segno e il gioco è fatto. per fare il segno vicino il bordo??? prendi un filo di ottone lo rigiri che ti vengono due punte e fai il segno. senza prendere un compasso. ciao ilario da firenze
