The production of silicone heat transfer trademarks using a dispensing machine mainly involves the steps of silicone raw material preparation, dispensing, mold vulcanization and shaping, cooling and demolding, and post-processing. The following is the specific production process:
Silicone raw material preparation: Mix the silicone raw material with the color paste, stir evenly, add the cataylst and mix again. Then put the mixed raw materials into the vacuum table for vacuum treatment to remove bubbles and prevent pores after molding. Pour the vacuumized raw materials into the barrel of the dispensing machine.
Dispensing: Use a 12-color dispensing machine to automatically dispense glue according to the programmed trajectory and evenly apply the silicone raw material on the mold. The dispensing process is accurate and efficient, which can ensure the accuracy of the silicone pattern.
Mold vulcanization and shaping:
Apply a hot melt adhesive film on the mold coated with silicone.
Put the mold into the silicone trademark integrated machine for vacuum vulcanization and shaping. The vulcanizer heats and pressurizes the silicone material to make it fully flow and solidify.
Cooling and demolding: After the operation is completed, the machine automatically pushes out the mold and puts the mold on the cooling table for cooling. After cooling, use tweezers to take the finished product out of the mold and remove the excess scraps. In this way, a silicone trademark is ready.
Post-processing: The finished silicone trademark is trimmed, cleaned, dried and other post-processing procedures are carried out to ensure that the edges of the trademark are neat and the surface is clean.
