Vacuum Investing and Casting-Support Equipment without a Furnace
When your workshop already melts metal, a vacuum-support unit may address a separate investing or casting task. Relia reviews the required operation, flask interfaces and supplied accessories, keeping the exclusion of a melting furnace explicit.

RELIA · PRODUCT AND MANUFACTURING SUPPORT
Identify the vacuum operation you need
Relia's vacuum-support enquiry starts from the established supply boundary: the referenced units do not include a melting furnace. Relia connects the selected operation to chamber or flask dimensions, pump, seals and adapters. This helps your team assess the unit as part of its existing workflow rather than assume it provides every step of lost-wax casting.
| Your requirement | Relia product and service scope |
|---|---|
| Established scope | Vacuum-support unit without melting furnace |
| Buyer inputs | Operation, flask size and existing connections |
| Confirm before order | Pump, chamber, adapters and temperature-related interface |
| Separate equipment | Melting furnace and burnout oven where required |
02 · COMPATIBILITY
Check the existing workstation interfaces
- Existing workstation
- Provide flask, plate and process connections.
- Compatible interface
- Agree how the support unit fits the actual workflow.
Share flask, working-plate and process-connection requirements. The new unit needs an agreed relationship to the existing equipment rather than an assumption based on a similar bell-jar photograph.
Technical notes
Confirm pump inclusion, chamber or bell dimensions, flask adapter and connection sizes. List the melting furnace and burnout oven separately. Do not infer heating power, alloy capacity or maximum casting temperature from a product whose established description says Without Melting Furnace.

MANUFACTURING ROUTE · FEATURES AND CONTROL
Separate Vacuum Investing From Melting and Burnout
Vacuum can serve different purposes: removing entrained air during investment preparation or supporting a selected casting operation. Those tasks have different chamber, sealing and temperature-interface needs. Relia's equipment review identifies the exact function and its connection to the existing furnace, flask and pump arrangement. The package then states which pump, adapter or seal is included. Acceptance is defined for that operation with a relevant vacuum measurement and test setup, rather than inferring a metal capacity from a support-unit photograph.
- Identify the missing functionInvestment preparation or defined casting support
- Match the interfacesFlask/chamber, seals and connections
- Define supplied itemsUnit, pump, adapters and exclusions
- Test the intended operationConditions and agreed acceptance criterion
04 · SCOPE
Keep exclusions visible in the package
- Supplied equipment
- Define the vacuum unit and included items.
- Separate items
- List furnace, fixtures and other required accessories.
These references do not include a melting furnace. List any other items required separately, including fixtures and process accessories, so the equipment quotation matches your existing workshop.

05 · WORKSHOP CONDITIONS
Plan installation from the actual configuration
Confirm electrical supply, connections, placement and operating documentation. Review any installation or training work as an explicit part of the agreed supply and handover scope.
06 · HANDOVER
Agree a functional acceptance check
- Functional check
- State vacuum requirements with measurement conditions.
- Quotation boundary
- Identify pump, seals, adapters and excluded equipment.
Request the actual configuration sheet and define the acceptance check for its intended operation. Include vacuum-performance requirements with measurement conditions, not a bare vacuum number. The quotation should distinguish supplied unit, pump, seals, adapters and excluded equipment.

07 · PURCHASING
Quote the addition alongside the existing equipment
Retain the current workshop interfaces and the added unit’s scope together. Make missing pump, fixture or process inputs visible before accepting the equipment package.
Technical notes
Identify whether the unit is needed for vacuum degassing, flask support during casting or another defined operation. Provide flask dimensions, batch volume and existing equipment connections. A vacuum chamber used for investing and a casting station exposed to a hot flask have different configuration needs.
| Scope | Retain |
|---|---|
| Existing station | Relevant interfaces and requirements |
| Added unit | Confirmed functions and accessories |
| Handover | Documents and functional acceptance |
