Overview of the Equipment
The vacuum drying oven is designed specifically for drying heat-sensitive, easily decomposable, and easily oxidizing substances. When working, it can maintain a certain degree of vacuum in the studio and be able to fill the interior with inert gas. Especially for some items with complex components, they can be quickly dried. It uses an intelligent digital temperature regulator for temperature setting, display, and control.
Description of Baking Trays
| No. | Content | Parameter Description |
| 1 | Stamping Baking Tray | One press is beautiful and elegant. It is divided into straight-edge baking plates and rolled-edge baking plates. Rolled-edge baking plates are prone to dead corners and cannot be cleaned thoroughly, gradually being eliminated. The mainstream product is a straight-edge baking tray, with thicknesses of 0.8, 1.0, and 1.2mm. Divided into mirror and frosted baking discs, with holes at the bottom. |
| 2 | Hand Welded Baking Tray | Hand welded, with a baking tray thickness of 1.5mm, can be used as a dual mirror clean baking tray. The bottom of the baking tray has a high level of flatness. Easy to take and transport with eight sloping edges on all sides. |
The Description of Water Tank
| No. | Content | Parameter Description |
| 1 | Heating Water Tank | The heating sources for water tanks are divided into electric heating water tanks and steam heating water tanks. The types of water tanks are divided into closed-water tanks and open-water tanks. Closed water tanks have fast heating, small volume, low energy consumption, and a small footprint. The open water tank has a large volume, slow heating, high energy consumption, and a large floor area. |
Description of Vacuum System
| No. | Content | Parameter Description |
| 1 | Vacuum Pump System | When the vacuum requirement is low, use a water ring vacuum pump, and the vacuum degree can meet -0.096Mpa. When high vacuum is required, a vacuum unit can be configured to meet the requirements of high vacuum and high heating efficiency. At this point, the vacuum degree can meet the requirement of less than 50pa. |
