Product Introduction
The Dual Layer Jewelry Flask Preheating Furnace is a purpose-built benchtop unit designed for flask preheating and plaster investment mold preparation in jewelry casting workflows. Its removable separation plate converts the 150 x 150 x 200 mm chamber between single-layer and dual-layer use, allowing casting studios to process either one taller flask or two smaller flasks in one cycle.
With a maximum temperature of 1150°C, digital temperature control, and a built-in observation window, this furnace helps operators prepare investment flasks before casting while keeping the heating process easy to monitor. The compact tabletop structure is suitable for jewelry casting studios, goldsmith workshops, jewelry schools, training centers, and casting supply distributors.
The dual-layer design is the key value of this model. In single-layer mode, the removable plate is taken out to use the full 200 mm chamber height. In dual-layer mode, the plate creates two separate chamber levels: an upper section of 100 mm and a lower section of 97 mm, allowing two smaller flasks to be preheated at the same shared temperature setting.

Key Features
Removable Separation Plate
Switch between single-layer and dual-layer chamber use without tools. Use the full chamber height for taller flasks, or install the plate to preheat two smaller flasks in one cycle.
Single or Dual-Layer Workflow
The flexible chamber design supports different casting jobs, from taller custom flasks to smaller batch production work for rings, earrings, pendants, and small components.
1150°C Maximum Temperature
The furnace reaches up to 1150°C, covering common flask preheating needs for jewelry casting and plaster investment mold preparation.
Digital Temperature Control
The digital display controller lets users set and monitor chamber temperature during the heating cycle. Both chamber levels share one temperature setting and one heating system.
Observation Window
The front observation window allows operators to check flask condition without opening the chamber door, helping reduce unnecessary heat loss during preheating.
B2B-Friendly Configuration
Voltage options, plug types, logo service, packaging options, and accessory configurations can be discussed for wholesale and distributor orders.

FAQ
Q: What is the Dual Layer Jewelry Flask Preheating Furnace used for?
A: It is used for flask preheating before casting and plaster investment mold preparation in jewelry casting workflows.
Q: Can this furnace be used for wax burnout?
A: No. This furnace is designed for flask preheating only. A separate wax burnout process is required before using this furnace for preheating.
Q: Can it be used for melting metal?
A: No. This is a preheating furnace, not a metal melting furnace. For melting applications, use a dedicated melting furnace or torch setup.
Q: What is the difference between single-layer and dual-layer mode?
A: In single-layer mode, the separation plate is removed and the full 200 mm chamber height is available. In dual-layer mode, the plate is installed and two smaller flasks can be preheated at the same shared temperature setting.
Q: Can both layers run different temperatures?
A: No. Both chamber levels share the same heating system and one temperature setting. They do not support independent temperature programs.
Q: What size flasks can I use?
A: Single-layer mode supports flasks up to about 200 mm height. Dual-layer mode supports flasks under 100 mm height per level. Keep at least 25 mm clearance around the flask.
Q: What voltage options are available?
A: The furnace is available in 110V/60Hz and 220V/50Hz options. Plug type can be arranged according to destination market requirements.
Q: Do you offer wholesale or distributor support?
A: Yes. Tooltos can support volume-based quotation, custom packaging, private labeling, and accessory configuration for qualified B2B orders.
