غطاء زجاجي 9 × 8 بوصة لآلات الصب بالتفريغ

The ground bottom rim sits perfectly flat on my casting machine, no wobble at all during the whole cycle. Thick walls too, so I don't feel like I'm about to crack it every time I set it down.

The acrylic is way clearer than I expected, so I can actually watch the whole casting cycle without lifting the jar. Thick walls and that ground bottom rim give it a nice solid seat on the machine.

I’d been worried about clarity, but the perfectly clear acrylic lets me watch the whole vacuum cycle without any distortion. The smooth, heavy bottom rim also makes it feel stable on the table. Only wish the opening were a touch wider for easier cleaning.
