Vac-U-Vest #15 Investment Mixing Machine: 6-Flask Professional Capacity
The Vac-U-Vest #15 is a high-performance vacuum investing system engineered to bridge the gap between boutique studios and full-scale industrial casting houses. Manufactured in the United Kingdom, this robust unit provides professional vacuum investing for up to 6 flasks simultaneously. By integrating intuitive controls with a heavy-duty design, the Vac-U-Vest #15 ensures consistent, bubble-free results in every production cycle, eliminating the variables that lead to surface defects and metal porosity.
Streamlined Production Control
Maximize your workshop's efficiency with a system designed for rapid turnover and flawless execution.
- 6-Flask Capacity: Optimized for mid-to-high volume production, allowing you to invest multiple flasks in a single vacuum cycle.
- Precision Mixing Blade: Features a unique blade design that "unfolds" the investment under vacuum, ensuring 100% air removal from the slurry.
- Vacuum-Sealed Pouring: The mixing and pouring stages are coupled within a sealed environment, protecting the mold from air entrapment during the critical fill stage.
- Intuitive Interface: Simplified controls allow operators to achieve professional-grade results with minimal training and maximum repeatability.
Rugged British Engineering
Built for the rigors of a daily production environment, the #15 model prioritizes both machine longevity and operator health.
- Dust Containment: The fully enclosed chamber keeps silica dust particles trapped inside, drastically improving the air quality of your casting room.
- Stainless Steel Turntable: A durable internal turntable allows for the easy positioning of each flask beneath the pouring valve without breaking the vacuum seal.
- Heavy-Duty Construction: Designed with industrial-grade components that withstand the continuous vibration and pressure cycles of a busy shop.
- Integrated Water Wash: Features a built-in wash system for rapid cleanup between batches, keeping the mixing tank clear of hardened slurry.
Consistent Quality for Every Cast
Success in jewelry manufacturing depends on a predictable, repeatable process. The Vac-U-Vest #15 removes the human error often associated with manual investing by providing a controlled, air-free environment for both gold and silver casting. Its 6-flask capacity makes it an ideal workhorse for expanding shops that need to increase their daily output without sacrificing the fine detail and surface finish of their jewelry. Whether you are casting intricate filigree or solid heavy bands, this unit provides the professional-grade vacuum environment necessary for superior results.
