Vacuum Forming- Making a Master Buck From an ABS Mold

[@ChadsCustomCreations]

This is a great video, I am currently putting together a video with vacuum forming trying to make it educational in a way. Would you allow me to use some small clips from this video if I was to tag you and your channel?

[@PacificMoldDesign]

Absolutely. The more education that can be shared, the better.

@@PacificMoldDesign man that rocks, thank you so much for being willing!

[@keithburk9383]

Did you build the vacuum forming machine I like the design with the draw style heat bed and air ram for the buck. Great video thx

[@markgrayson4460]

Cool video. I have seen a few comments asking which brand and model of machine this is. Is it secret? Looks like a cool unit, is it possible to Get the model and brand of it?

[@Motorstorefrance]

Hello ! Where you buy your machine please or How I can build this ? Thank you so much :D

This link appears to be broken. It goes to main page but not to a place where I can order vac25

[@tiffanyjohnson3110]

Can you make smaller skull molds? I ordered your smallest ones & they're still too big & deep. I'm using air dry paper clay & I don't need them so deep cuz I adhere them to furniture & other touchable objects.

[@PacificMoldDesign]

Tiffany Johnson unfortunately no. We are working on several new items and expanding the offering.

@@PacificMoldDesign alrighty then, ty anyways.

[@chrome72]

What material did you use for the heated plastic?

[@PacificMoldDesign]

This iteration uses recycled ABS

[@chrome72]

Is there a lot of flex in the former abs? Like if you painted it would the paint crack because the abs isn’t rigid enough? Thanks for taking time to answer me

[@PacificMoldDesign]

@@chrome72 the material is compatible to a vehicle dashboard. It does flex

What is the thickest plastic sheet vaccum forming can handle?

[@PacificMoldDesign]

That really depends on the type of plastics being used and type of machine. For example, some machines have smaller heating elements which handles thinner/lower temp materials. Think about RC car bodies, plastic containers ect. Other industries that make things like hot tubs will need a larger unit with a massive heating element, vacuum chambers and pumps.

Life of die ?

[@PacificMoldDesign]

Depends on your item. 3-500 cycles

1. Bleed holes are always put in corners or along edges unless absolutely necessary. Not out in the middle of a surface. Why, because then you don't have to worry as much about them showing up in your final part. You can then use different thickness of materials and not worry. 2. You didn't affix the buck to the lower platen. You end the video showing the buck lower down like the plastic is coming off the buck. But that was faked, clearly it would never do this because YOU DIDN"T ATTACH TO PLATEN! 3. Buck material is wrong for real production runs, you want something with metal powder for longer tool life and better heat tolerance. Your tooling should last years if you choose the correct heat tolerant material. Both VAC 25 and 50 have terrible heat resistance for production vacuum forming. You generally want something closer to 300F and better. Many vendors out there offer better material. Alumilite products in general are hobbyist grade. They are not horrible just not what most pros would use.

[@PacificMoldDesign]

To your second point, we used a strong draft angle on this buck to avoid the need to attach to the platen. This allows for buck placement flexibility. This works for me... The buck material has survived well over 5000 pulls to date. Again, this works of our needs.

[@vampcaff]

Smoothon epoxacast 670HT. You act like there's some secret industrial material that's different from hobby grade. Too funny.

[@oldapplegaming8045]

@@vampcaff If you look at and buy industrial you would know they have better heat deflection, and options for higher aluminum content. Smooth-On is notorious for bubbling up and expanding under high heat required for tooling that needs to be heated. That is partly the blend they use and the low aluminum content.
