Comprehensive description plastic injection molding brands hot stamping technology _ injection plate _ plastic hot stamping technology

Comprehensive description plastic injection panels stamping stamping technology is one of the commonly used plastic injection molding plate surface decoration process, strong decorative and better economy, simple process, the characteristics of wide application. Choose different hot stamping foil, gold, color can be obtained, silking, matte, and the decorative effect of different natural texture. Hot stamping technology can not only make texture and appearance of the plastic injection molding sign change greatly, at the same time also can be used in the decoration on the surface of the material. The following process technology content to make a brief introduction: 1. Choice for plastic injection molding plate stamping machine: a flat hot stamping machine, hot machine and climbing. Flat machine have two optional manual and mechanical. Scalding machine is suitable for mass production of plastic hot stamping signs, will climb hot stamping machine is suitable for curved panels stamping. 2. Hot stamping foil choice according to different materials with different varieties of hot stamping foil, hot stamping foil, many varieties have chromium electrochemical aluminum foil, foil, foil paint, wood grain foil and other varieties, there's a light at the end of the surface color gold silver, brushed gold silver, brush lines of gold, silver and other electrochemical aluminum products. There are different grades of, each have characteristics. Such as high abrasion resistance of electrochemical aluminum, rapid stripping electrochemical aluminum, etc. , suitable for different needs. When the choose and buy hot stamping foil, also can choose the hot stamping foil of a domestic joint venture, but must first try very hot, and quality is maintained, and used to mass production. 3. Choose hot stamping silicone rubber heating plate has different thickness: such as 0. 8毫米,1。 6毫米,3。 Different specifications such as 2 mm. Generally for shore hardness 70 ~ 80 & deg; , bottom plate for aluminum plate, small, fine lines and the use of thin silicone version, characters of broad-brush version is heated with thick silicone rubber. 4. Plastic injection plate stamping quality requirements: the appearance quality requirements are clear, complete line is straight and clean surface, uniform color, no color, no blister, blister defects affect the appearance. About internal quality requirements, different users have different requirements, in general, such as adhesion, abrasion resistance, ethanol resistance, resistant to salt water, surface hardness, heat resistance and other requirements, according to the enterprise standard inspection and recognition of users. 5. Stamping twill methods: made of PC plastic surface high speed cutting with diamond tools out of twill, the thickness of the grain is associated with the geometrical angles of diamond tool. After the diamond tool cutting plastic surface convex word, using electrochemical aluminum foil stamping and hot stamping machine. 6. Hot stamping temperature, pressure, time selection method is: the range of a hot stamping temperature to reach the hot stamping foil adhesive and plastic surface solid combination, hot stamping film stripping is good for you to complete. Hot stamping is the combination of heat and pressure, temperature, pressure, time to cooperate, to the principle of workpiece deformation character cannot become coarse, line can't collapse edge, time should be short, as far as possible to iron through the test to confirm the temperature, pressure and time. 7. The method of making plastic injection molding sign with PC plastic and ABS plastic grain, the use of injection molding machine and mold injection molding. In order to guarantee the quality, the best equipped with mould temperature controller. Now mould is used in the production high quality product of casting method, electricity, to ensure that the surface has a high degree of finish. Also high precision injection molding machine, by computer control temperature, pressure, time to ensure the quality of injection molding. 8. The working principle of hot stamping: refers to the hot stamping foil surface of the metal coating on the transfer to the products, make plastic injection sign with metallic simple sense, in order to reach polychromy effect. 9. Note: hot stamping production must be surrounded by as the center, to make the graphic clarity, deformation, maintain a good image as the key point, when hot stamping, should pay attention to the points: (1) to stamping, plastic injection molding plate surface cleaning treatment, selection of a suitable hot stamping foil, adjust the temperature of the hot stamping correctly. (2) try to very hot a few small kind, hot press pressure at high speed, control the depth of the hot stamping, then to control the depth of the positioning and locked. (3) after reaching a certain depth, to master a good hot stamping time, lift the hot stamping iron as quickly as possible. Can't repeat hot press, repeat will make products to blur, double strokes, and by not light. (4) pay attention to control the pressure, especially in soft plastic, pressure will make staying at the handwriting, handwriting deformation, when hot stamping to destruction by the edges and corners of edge horn shall prevail.
