Principle of resin hot melt welding machine: The method of using Joule heat generated when pulse current flows through high resistance materials such as molybdenum and titanium to heat and weld. Press the plastic rivet under the welding head, and the welding head will instantly heat up (1 second). The temperature control accuracy of the welding head can be controlled within 3%. The heat of the welding head acts on the plastic rivet, causing it to melt and produce a "mushroom" shape. After cooling (1-3 seconds), the welding head lifts up and the welding is completed.

1： Resin hot press product description:

Cooling function: It ends after the resin solidifies, so stable welding without resin pulling can be achieved.

Temperature feedback function: It can suppress temperature fluctuations caused by environmental and temporal changes. Realize stable welding based on temperature feedback. (There will be no resin splashing or cracking during ultrasonic welding.)

Cooling function: It ends after the resin solidifies, so stable welding without resin pulling can be achieved.

Used in various plastic molds for plastic column hot melt, hot melt adhesive, and nut heating embedding processes.

Welding characteristics:

1. The temperature of the welding head can be instantly raised, with precise temperature control within 3%;

2. Pressure can be precisely controlled;

3. The bottom of the rivet will not be damaged or broken.

4. It can achieve automated operation and weld several points at once.

2： Characteristics of plastic hot pressing machine:

1. Adopting advanced segment control temperature control system, the heating status of each segment can be flexibly set. Can control parameters such as temperature and time with high precision.

2. The rapid and stable heating, as well as the local instantaneous heating method, can effectively suppress the thermal impact on surrounding components.

3. Heating and cooling are carried out simultaneously during pressurization, preventing the joint from floating and virtual welding.

4. Display the temperature of each stage.

5. The closed-loop online feedback control of thermocouples improves the accuracy of temperature control, with a temperature control accuracy of around 3%.

6. Welding pressure, welding time, and welding temperature can be precisely adjusted.

7. It is very convenient to store 20 sets of welding parameters for product replacement.

8. Multiple solder joints can be completed at once, with high efficiency, good consistency, high welding strength, beautiful solder joints, and simple operation.

9. A welding head lifespan of 100000 times, creating value for your customers
