Servo Motor Hot Plate Welding Machine
The servo motor hot plate welding machine functions by heating the surfaces of individual components at the designated welding area and plasticizing them. Once heated, the two separate components are pressed and welded together using a vertically moving upper tool and a lower lift table.
The machine includes an upper tool and a lower tool, in which the respective components are fixed securely.
Operator Station
This is the designated operator station, also referred to as the embedding and extraction station.
The operator follows the manual production procedure and places a single component into the welding fixture.
Operator Procedure – Embedded and Extraction:
Embed the single component
Press the start button
Observe the equipment controller located on the right side of the station
Once welding is complete, take out the finished welded part
Embedded and Extraction Station Operator Manual Movement:
- Embed single
- Press start
- Observe the equipment controller from the right side of the operating
*Take out the welded complete part after the welding is finished.

Transmission Unit (Actuating Device)
Risk Warnings:
Risk of damaging or crushing the transmission unit
Risk of pinching between upper and lower dies
Risk of injury during die feeding movement
Horizontal Transmission Unit
The horizontal movement is powered by a servo motor and reducer, which drives a gear rack mechanism. This moves the hot tool sliding table horizontally.
This system features high load capacity and precise transmission.

Horizontal Transmission Unit
Horizontal movement: through reducer, the servo motor transmits the power to the gear rack mechanism to drive the hot tool sliding table to move horizontally. The gear rack transmission is characterized by high load bearing and high transmission precision.
Lower Transmission Unit
The vertical movement is powered by a servo motor and reducer, which drives a gear rack mechanism to move the lower cold die sliding table vertically. This mechanism ensures high precision and load capacity.

Manual Communication Valve (Compressed Air Supply)
Danger of eye injury caused by a bouncing hose!
The pressure storage device may pose a risk — this danger can also occur during an emergency stop.
Pneumatic equipment must be brought to a no-pressure condition before any operation.
This is automatically handled when the air supply valve is closed, completing the exhaust process.
Danger
→ Use the manual communication valve to turn the compressed air supply ON or OFF.
The compressed air supplied to the start-up control equipment assembly is processed by the maintenance unit.
At an operating pressure (nominal pressure) of approximately 6 bar, condensed water will accumulate and settle in the supply line.
