The control method of medicinal cosmetics plastic hose controls

cosmetics plastic hose manufacturer of plastic pipe and other cosmetic plastic molding, molding is molten cosmetic plastic fluid into a fixed geometry products process, therefore must be in a certain temperature range to shape. Forming the cosmetic plastic fluid in addition to do mechanical movement, also with the surrounding medium heat transfer, by cooling to hardening, cosmetic plastic first by viscous liquid into a plastic state, and then into a brittle solid state. Thus cosmetic plastic forming process is extremely complex, is a combination of a variety of different effects. The mechanical and thermal effect is of great significance.

medicinal cosmetics plastic hose plastic molding belongs to no mold molding, the process is simple, but its forming process is divided into molding and finalize the design of two stages. The first stage is a fu son cosmetic plastic pipe with a certain diameter size, the second stage is to put the cosmetic plastic pipe fixed shape. Cosmetic plastic molding and finalize the design is continuous, finalize the design is actually the continuation of the molding, but the time required to finalize the design than the molding time is long. The key factors of forming stages is cosmetic plastic rheological properties, decided to finalize the design phase of the factor is the thermal properties of cosmetic plastic and in the surrounding medium under the influence of cosmetic plastic hardening rate.

medicine with the control method of cosmetic plastic Dana method ( 丹纳过程) And dimensional method ( Vello process) ) Two, belong to a level drawn tube method. At present in our country with the more common is Dana drawn tube method.
