HOW TO… PART 4 ‘CENTRIFUGAL CASTING’
In this episode you will see exactly how I cast my aircraft using the vulcanised rubber moulds made in episode #3. I use a centrifugal casting machine for all my production casting. It is a relatively simple piece of equipment with the skill being how to adjust its various settings to get the best quality castings possible.

This is fantastic! I've been looking for a detailed HOW TO on spin casting for fishing weight production. After watching this series, I can't think of any questions I have after this series! So great!

@StaplesandVine 4 месяца назад

Glad you found my video useful. Good luck with the fishing weights. 🙂

wonderful video! Do you know if this type of moulds can resist brass?

@StaplesandVine 2 года назад

Hi Rubeno, glad you liked the video. Unfortunately rubber moulds are totally unsuitable for brass casting, they will just catch fire - not good. Try searching 'lost wax / investment casting' . That is how brass is traditionally cast

Great video series! I love your videos in general. Im new to these processes for pouring pewter and had few questions. I was wondering what makes you choose the vulcanized rubber method vs the silicone? Is one better for some things then others? Does one result in better details? Also I was just curious, I questioned it and wavered back and forth but what makes you choose to do pewter castings over “cold-casting”? if you have tried that. Thank you in advance for any help and information.

@StaplesandVine Год назад

Thanks Justsomeguy glad you like the series. Lots of questions... 1. Vulcanised centrifugal rubber moulds give far better quality castings than the cold cured silicone with less distortion and finer detail. 2. Cold cure silicone moulds are only used by me for one-offs or to convert a 3d printed part into metal. 3. Silicone centrifugal moulds are available but are more expensive. 4. Resin / cold casting is fine but fails cannot be re-cyclyed unlike pewter castings which are just re-melted and you go again. 5. Tried resin casting - didn't like it. 😁

@Willy_Milano Год назад

Very nice. I thought that material was zamak. Do you also use it for your castings?

@StaplesandVine Год назад

I only cast in pewter. Zinc based alloys require a much higher temperature and are more dangerous to cast with.

@lancelottavola9685 2 года назад

I wondering what will hapens if you directioned the vent channels direct to the large feeding hole instead to the boards,be careful,I dont know if it spit the metal out,so its just one experiment...maybe it will be no problem to use high speed for beter detail in casting if the system work.

@StaplesandVine 2 года назад

Hi Lancelot, thanks for your comment. The molten metal will fill and block any air vent it comes into contact with so they must be kept separate at all times. Getting the air out is crucial for successful casting.

Depending on how hot the mould is run and the design of the parts the mould should withstand at least 500 castings.

It sounds like the grade of rubber is not suitable for the type of metal you are casting. What metal and rubber are you using?

@user-nm8sv4be3r Год назад

www SETEK rubber. 4%aluminum . 1% cuprum . the rest is zinc

@StaplesandVine Год назад

Even high temperature rubbers don't like Zinc casting (420C) . I suggest you speak to your rubber supplier and ask them to recommend a rubber for your application. If they can't supply you may have to consider a lower temperature metal (Tin alloy).

Hi Viggo, NO this method does not work for Aluminium. Aluminium melts at 660C, using this method you will end up with a fire and probably a visit to the hospital.

@ParadigmUnkn0wn 2 года назад

You can centrifugally cast aluminum, just not using this machine and rubber molds. I've never seen a centrifugal casting setup for aluminum that even comes close to being practical for the home shop hobbyist, or even small production shops. Stuff like that tends to get outsourced. I did see a very crude home setup here on RU-vid, but that rig didn't even have a containment shield. Even with a full fire suit I wouldn't be caught near a contraption like that. No casting project is worth suffering severe, possibly debilitating or fatal, burns.

The masters are often 3D printed or sculpted in Milliput then they are 'translated' into metal using the processes described in the 3 previous how to videos. 🙂

Definitely not, unless flames, explosions, fire-engines, ambulances and a trip to hospital are on your agenda. This process is for tin based alloys only.

@@StaplesandVine thats what i was thinking, but never delt with vulcanized rubber. and figured it was worth a quick ask.

@WhenDoesTheVideoActuallyStart 2 года назад

You're throwing a lot of oxides back into the melt. I wonder how badly it would affect the material properties in the last batches.

@StaplesandVine 2 года назад

The oxides are skimmed off the molten pewter frequently and the regular addition of fresh metal keeps it in good condition. Fluxes are added at the end of a casting session. But to be honest the behaviour of the metal remains very consistent. Atmospheric conditions have a greater affect

@marcosgutierrez373 Год назад

the metal used is aluminium?

@StaplesandVine Год назад

No, I cast in Pewter which is a Tin based alloy. These moulds would not withstand the high temperatures needed for Aluminium casting.

Solo estoy colando a 290-310 C, lo que no causa ningún problema para el molde. Algunos de mis moldes tienen 20 años.

@jasonlanning2394 6 месяцев назад

Why are the vents cut to the perimeter? Could they be brought back closer to the center, ensuring to avoid feed mouths and drilling to the top of the mold? Would this prevent overflow spilling. Thank you for the wonderful layout of your videos. They are very educational and provide all the right information.

@StaplesandVine 6 месяцев назад

Thanks for the comment Jason. The metal flowing down the vents is not a problem as the excess is easily removed on clean up. The primary goal is good casting quality which is way more important and more difficult to achieve. 🙂
