Embodiment 1
[0029] see figure 1 , the present invention provides a kind of technical scheme: a kind of automobile control panel IMD injection molding process, comprises the following steps:
[0030] Step 1: Cut PVC or PET sheets;
[0031] Step 2: The cut sheet is placed in a 100,000-level purification workshop for purification; a 100,000-level purification workshop means that the particles per cubic meter in the workshop are controlled within 10W;
[0032] Step 3: After purification, take out the sheet and place it in a dryer for baking at 90°C for 2 hours;
[0033] Step 4: After baking, use light-curable ink to screen-print the sheet. The mesh number of the screen is 120 mesh / cm monofilament polyester screen; screen printing can be automated, with high production efficiency and UV ink light. Curing only takes a few seconds or more than ten seconds. The curing speed is very fast, and finer lines can be screen printed. The resolution is high, and the ink layer is thinner, and the printin...

[0041] Step 1: Cut PVC or PET sheets;
[0042] Step 2: The cut sheet is placed in a 100,000-level purification workshop for purification; a 100,000-level purification workshop means that the particles per cubic meter in the workshop are controlled within 10W;
[0043] Step 3: After purification, take out the sheet and place it in a dryer for 1.5 hours at 105°C;
[0044] Step 4: After baking, use light-curable ink to screen-print the sheet. The mesh number of the screen is 143 mesh / cm monofilament polyester screen; screen printing can be automated, with high production efficiency and UV ink light. Curing only takes a few seconds or more than ten seconds. The curing speed is very fast, and finer lines can be screen printed. The resolution is high, and the ink layer is thinner, and the printing area i...

[0052] Step 1: Cut PVC or PET sheets;
[0053] Step 2: The cut sheet is placed in a 100,000-level purification workshop for purification; a 100,000-level purification workshop means that the particles per cubic meter in the workshop are controlled within 10W;
[0054] Step 3: After purification, take out the sheet and place it in a dryer for baking at 120°C for 1 hour;
[0055] Step 4: After baking, use light-curable ink to screen-print the sheet. The mesh number of the screen is 165 mesh / cm monofilament polyester screen; screen printing can be automated, with high production efficiency and UV ink light. Curing only takes a few seconds or more than ten seconds. The curing speed is very fast, and finer lines can be screen printed. The resolution is high, and the ink layer is thinner, and the printin...
