I. Product Overview
The spin welding machine operates on the principle of rotational friction heat generation to rapidly melt and precisely weld the contact surfaces of plastic parts. This high-efficiency equipment eliminates the need for glue or screws, providing high weld strength and excellent sealing. It is widely used for welding circular plastic workpieces such as water cups, filter elements, and household appliance accessories. Simple to operate, stable, and durable, it is an essential assistant for plastic processing.
II. Safety Instructions
Before startup, ensure the equipment is properly grounded and the wiring is intact. Never operate with wet hands to prevent electric shock.
While the machine is running, do not place hands or clothing near the rotating stations or mold areas to prevent crushing or burn injuries.
Before changing molds or adjusting parameters, you must disconnect the power and ensure the equipment has come to a complete stop before proceeding.
Keep the work environment dry, clean, and well-ventilated. Stay away from flammable and explosive materials to eliminate hazards.
Unauthorized or untrained personnel are strictly prohibited from disassembling or modifying the internal structure of the equipment.
III. Operating Procedures
1. Startup Preparation
Connect the power and air supply. Check that the air pressure is stable between 0.4 and 0.6 MPa. Turn on the power switch to enter standby mode.
2. Mold Installation
Accurately fix the upper and lower molds into their respective stations. Tighten the screws to ensure the molds are secure and properly aligned for welding precision.
3. Workpiece Placement
Place the upper and lower plastic workpieces into the respective molds. Ensure they are positioned correctly and stably without tilting.
4. Parameter Settings
Adjust the rotation speed, welding time, and pressure based on the material and size of the workpiece. Matching parameters will ensure optimal welding results.
5. Initiating Welding
Press the start buttons with both hands (safety anti-mishap design). The equipment will automatically complete the rotation, friction, melting, and pressure-holding stages.
6. Removal & Inspection
After welding, the equipment resets automatically. Remove the finished product and check that the weld is crack-free, without excess overflow, and firmly sealed.
IV. Maintenance and Care
After daily work, clean plastic debris from the molds and workbench to keep the equipment tidy.
Regularly apply lubricant to sliding parts and bearings to reduce wear and extend service life.
Periodically inspect the air source, circuits, and screw tightness. Stop the machine immediately if any abnormalities are found.
When not in use for an extended period, cut off the power and air supply, cover with a dust shroud, and store in a dry environment.
V. Troubleshooting
Weak Welding： Check if parameters are correctly matched, if the workpieces are aligned, or if the molds are loose.
Excessive Overflow： Appropriately reduce the welding time and pressure, and adjust the fit of the workpieces.
Equipment Fails to Start： Check if the power and air supplies are connected and ensure the emergency stop button has been reset.
