Aluminum cosmetics hose printing process introduction

Aluminium cosmetics hose printing process introduction in the metal hose, aluminum tube with high strength, beautiful appearance, light quality, non-toxic and tasteless, metal hose printing is curved surface printing, print for copper plate and photosensitive resin version, the trainees in offset printing technology: metal hose is mainly refers to the aluminum tube, after hot stamping and annealing aluminum billet began to enter the printing process. Metal hose features of paste has certain viscosity, adhesion and deformation, the use of flexible metal hose is more convenient, not only convenient for extrusion and completely sealed, can isolate external light source, such as air, water, fragrance is good wait for a characteristic, metal hose material processing convenience, high efficiency, product packaging and fast, cheap, welcome by consumer. According to the material of the hose, the use of metal hose is divided into three types: 1. Tin tin hoses hose is very expensive, and is rarely used, except for some special medicines, need because of the nature of the product. 2. Lead the hose lead poisonous and harmful to human body, currently in use is less, only used for fluoride products. 3. Aluminum tubes with high intensity, appearance beautiful, quality is light, non-toxic, tasteless, low prices. Widely used in cosmetics, toothpaste, medicine, food, household goods, pigment and other packaging. Aluminum metal hose production process in the production of aluminum tube method is aluminum plate stamping into cylindrical tube body, through the head and tail of the gear cutting processing after printing. From the end of wash pipe, internal coating, coating to printing, cover the whole process of completed in a pipeline automation production line. Printing process of aluminum metal hose 1. In the underlying oil and cosmetic PE hose and hose for aluminium, aluminium tube printing first need to bottom oil, color printing with white primer, coating thicker, smooth surface. In order to achieve special effects, the base can be replaced with different colors, like pink and light blue. 2. Dry the base must be bottom oil into high temperature oven to bake. The hose does not go brown when dry. There is a little viscosity best surface. 3. Printing patterns and text hose graphics is commonly used in the field, multi-color overprint don't overlap. Rubber tube rotary printing more than one time the hose. Tube on the spindle rotation plate, itself does not rotate, after contact with the rubber tube friction rotation. 4. Printing dry rubber hose must pass oven drying, drying temperature and time should be according to the ink oxidation resistance to choose.
