First, the hot stamping version is the primary factor to ensure the quality of bronzing
At present, the gilding plate is mainly made of photographic etching process and electronic engraving technology, and the material is commonly used in copper plate or zinc plate. The copper plate is fine, the surface finish and heat transfer effect are better than the zinc plate. The high-quality copper plate can improve the gloss and contour definition of the bronzing. The traditional photographic corrosion technology produces a bronzing plate with simple process and low cost. It is mainly used for text, thick lines and general images. For the finer, uneven image thickness, the bronzing plate needs to use the second bad depth or adopt electric carving technology. The electric gilding version can express rich and delicate layer changes, greatly expanding the packaging performance ability. This process is conducive to environmental protection, but the investment in electric carving equipment is relatively large. At present, the depth of engraving is not ideal enough, which is easy to cause bronzing. The holographic anti-counterfeiting hot stamping plate has high technical requirements. It was mainly produced in Taiwan or abroad, and the plate making cycle is long. It is only used for the packaging of fixed and bulk products. At present, there are several units in Shanxi Yuncheng, Beijing and Shanghai that can be produced.
Second, bronzing equipment "workers want to do their best, they must first sharpen their tools"
The selection of bronzing equipment is a key factor in determining the quality of bronzing. The sheet-fed stamping machine has three types of flat flattening, round flattening and round pressing. The most widely used ones are flat-pressing machines, mainly including: Shanghai Yahua Printing Machinery Co., Ltd. TYM series die-cutting hot stamping two Machine, Tangshan Yuyin Group's TYMl020 automatic bronzing die-cutting machine, Tianjin Youheng Machinery Industry Co., Ltd. MK series automatic bronzing die-cutting machine, the maximum bronzing speed is 5000 hours. Germany Stowe FOLLJETFBRl04 type bronzing machine is a circular pressing circle representative, using the design concept of the offset printing machine, the maximum hot stamping speed can reach 10,000 sheets, and it is the fastest single sheet bronzing equipment in the world. The three embossing methods of round pressing, round pressing and flat pressing have their advantages and disadvantages: round pressing, round pressing and hot stamping are line pressure, the total pressure is small, and the pressure is easily completed with relatively small pressure. Large-area hot stamping, smooth movement, and round and round production efficiency is high, especially suitable for large-volume hot stamping, but because the copper plate arc surface processing is more difficult, the production cost is higher, the heating roller is also more difficult than the plane heating. The flat pressing operation is flexible and convenient, and is suitable for short-run products. Compared with imported bronzing equipment, domestic bronzing equipment has obvious advantages in performance and price. The price of domestically produced machine is only equivalent to the price of similar foreign products, l5~14, but the precision, stability and function of imported machine are obviously better than domestically produced. The machine is also more durable than the domestic machine, and is more suitable for processing fixed-package high-end packaging products. Therefore, product type and batch size are the key to determining the selection of hot stamping equipment. Whether you have BOBST and other high-end stamping die-cutting equipment has become the preferred condition for customers in the industry.
