How to heat and vulcanize the molding compound

1. The standard vulcanization temperature is 165 degrees Celsius. Based on the 10mm die frame heating for 25 minutes, the vulcanization time of the die frame must be increased by 2 minutes for every additional 1mm of the die frame, and the die frame should not exceed 30mm.


2. Before adding vulcanization, the compression molding machine must be preheated to the set temperature of 165 degrees Celsius. When vulcanizing, the model to be vulcanized should be placed in the compression molding machine and gently pressurized for about one minute, and then the surface rubber is softened. silicone compression molding, Carry out the compression molding operation and start to calculate the compression molding time.


3. If the temperature of the compression molding machine drops more than 30% of the set temperature when starting the compression molding, and the compression molding machine fails to rise to 155oC within 10 minutes, the best vulcanization effect will not be achieved. It is recommended to use a larger one Compression molding machine with heating power.


4. The temperature display on the molding machine is not very accurate. Please use a temperature detector to measure the actual temperature on the molding machine when purchasing the molding machine to achieve the best vulcanization effect.


5. Natural cooling and water cooling can get the same result. When using water cooling, the cooling time can be shortened. The rubber mold still retains its plasticity when it is not completely cooled. Please do not open the mold.
