1. Purpose

This machine is a mid-frequency centrifugal casting machine, which is more stable for the casting of dental cobalt-chromium, nickel-chromium, and other metals. The melting power can be adjusted at any time. It is more user-friendly, making it an essential equipment for oral casting.

II. Technical Indicators

1. Power supply: AC 220V 50Hz (a voltage regulator is required in areas with higher voltages) Input power: 3KVA;

2. Centrifugal motor: 0.37KW

3. Ground resistance: shall not exceed 4 ohms

4. Maximum molten gold amount: 50 grams

5. Model: LZZP-I

III. Usage Instructions

1. Connect the device power cable to a power source with sufficient capacity. The ground wire must be securely attached. Turn on the power switch.

2. Place the casting ring on the U-shaped arm of the centrifuge, insert the steel crucible into the working coil, loosen the central pressure clamp, rotate the balance nut to bring the centrifuge into equilibrium, and then tighten the central pressure clamp. Move the molten metal working coil to the middle position between the two air vents, lower the upper cover, and observe that the locate indicator light is on and the door light is on. If the locate light does not turn on, it indicates that the working coil is not positioned correctly. Move the rotating arm again until the locate light turns on after lowering the upper cover.

3. Press MELT, rotate the POWER CONDITIONING knob to approximately 13A on the Voltage meter to observe the molten steel condition. Once the steel has melted, press CASTING and rotate the centrifugal arm. After about three to four seconds, press STOP. Once the rotating arm stops, open the upper cover and remove the cast. The melting time for 30G steel is approximately 70 seconds; if it exceeds this time, please stop the machine and contact the manufacturer.

4. It is recommended to adjust the knob to the minimum position after each steel melting process, and slowly increase it when melting next time.

4. Precautions

1. This machine uses an air-cooled cooling system. After each steel melting process, it is required to wait for 5 minutes before the next casting. After 5 consecutive castings, it must cool in standby mode for 20 minutes before the next casting. After the casting is completed, the power supply should not be turned off immediately; instead, it should cool in standby mode for 2 minutes.

2. Do not exceed 15A when melting steel; otherwise, the machine may automatically protect due to excessive power or experience malfunctions. The protective response of the machine is an absence of display on the ammeter, with no melting process. Adjust the power conditioning knob to the minimum and press melt again, then slowly increase the knob to the appropriate level!

3. During steel melting, not only should the value on the dccurrent (ammeter) be observed, but also the value on the select voltage (voltmeter) must be noted. When the melt button is pressed, when the dccurrent (ammeter) reads around 15A, the voltage drop on the select voltage (voltmeter) must not exceed 10V; otherwise, the melting process will take too long.
