Problems solved by technology
[0004] The above-mentioned processing technology can actually be applied to the processing of blow molding bottles made of various resin materials, including PET, PP, etc. The appearance is relatively ordinary, and it has no obvious features when placed on the dressing table. If you want to improve the aesthetics, you need to undergo additional processing to achieve the required aesthetics. In this way, you need to increase the process steps. The more process steps, in addition to the cost In addition to the corresponding increase, the processing time of the product will also be extended, resulting in low production efficiency

Abstract
The invention discloses a manufacturing process of cosmetic cracked bottles, which relates to blow molding technology and can solve the problem of poor decorative effects of cosmetic bottles made by common blow molding processes. The preform is formed by injection molding; then the preform is subjected to surface coating treatment; then the preform coated with film is heated and blown to form a cracked bottle; then the formed cracked bottle is sampled and tested for adhesion; Finally, the finished product can be packaged before leaving the factory; the present invention has the following advantages and effects: the processing sequence of first coating and then blow molding can make the coating layer crack during the blow molding process, so that the surface of the cosmetic bottle has a crack effect, and the cosmetic bottle is significantly improved. Compared with the ordinary process, the one-time molding process can reduce the processing steps and shorten the processing time, so it can improve the production efficiency of cracked bottles.
Description
technical field [0001] The invention relates to blow molding technology, in particular to a manufacturing process of cracked cosmetic bottles. Background technique [0002] After cosmetics are produced, they often need to be packed in cosmetic bottles. With the improvement of living standards, people's aesthetic consciousness is getting stronger and stronger, and gradually put forward higher aesthetic requirements for product packaging. [0003] At present, the Chinese invention with the authorized notification number CN108044914A discloses a processing technology for PE blow molding bottles, which includes the following steps: (1) melting of raw materials: heating and melting the PE raw materials in the barrel to reach a molten state; (2) Blank blow molding: The motor drives the screw to rotate to fully stir, squeeze and compact the PE raw material in the molten state, and then the screw extrudes the compacted PE raw material into the blow molding device at a constant speed...
