I purchased this VEVOR vacuum investing and casting machine for the GemStars Jewelry manufacturing workshop. The machine arrived well packaged and includes the vacuum pump, bell jar, pressure gauge, casting chamber, and accessories needed to begin setting up the jewelry-casting process. The machine feels sturdy, the controls are straightforward, and its compact size works well for a small jewelry-production workspace. I plan to use it for investment preparation and vacuum casting of custom rings, pendants, and other jewelry pieces. So far, I’m pleased with the equipment and the value it provides. I’ll have a better understanding of its long-term performance after completing more casting cycles, but the initial setup and build quality have made a good first impression.

Enige vertraging bij de levering, echter prima opgelost. Geweldig bruikbaar apparaat. Lees zeker eerst even de handleiding, en vergeet niet om vacuümpomp olie te bestellen. Voor het uitschakelen van de pomp zog dat het systeem drukvrij is anders zuig je de olie uit de pomp naar de vacuümkamer!
