[China Aluminum Industry Network] After hot printing is a high-quality technology, it is used more in cigarette pack printing, and its three-dimensional effect is beyond the reach of other technologies. After the hot printing, the large area laser electro-aluminum is generally stamped on the spot color ink, and then the UV ink is printed on the electro-aluminum. Its printing materials. Printing inks, printing equipment, and printers are highly demanding. The following points should be noted in this technology: 1 Select an electro-aluminum with a surface tension of (4.0-4.6) X10-2N/m to ensure that the ink has good adhesion. 2 In the hot stamping process, it should be noted that hot stamping does not allow paste version, reverse drawing, hot stamping and other appearances. Otherwise, the embossed aluminum stamped on the second printing will fall and accumulate on the blanket, which will seriously affect the product quality and production efficiency. 3 Summarize printing, hot stamping, and hot printing to control the ambient temperature and humidity of the shop, and try to prevent human factors from reporting. 4 When designing, it should be noted that whether it is possible to hollow out or separate hot stamping in a large-area field hot stamping to reduce the difficulty of hot stamping. Self-tapping threaded inserts are suitable for creating heavy-duty, wear-resistant and vibration-proof fastenings in materials with low shear strength, such as aluminium, brass, bronze, cast iron or duro and thermoplastics. Threaded inserts with cutting slot are available in steel and stainless-steel versions.
