Detailed introduction of lipstick tube of cosmetic packaging material
The lipstick tube is the most complex and difficult of all cosmetic packaging materials. First of all, we must understand why lipstick tube is difficult to do and why there are so many requirements. A lipstick tube is a combination of multiple components. Functional packaging composed of different materials can also be volatile and non-volatile in terms of the material body. In addition, most of the filling is automatic filling by machine, including the loading of a lipstick tube, which is very complex and the combination of different parts, Poor tolerance control or unreasonable design, even if the way of lubricating oil coating is wrong, it will cause shutdown or abnormal function. These errors are fatal.
Main functional parts of a lipstick tube
Bead fork screw is an important part of the lipstick tube, that is, bead, fork, screw, bead fork screw, and lubricating oil constitute the core of the lipstick tube. It is a bit like a pump core, but it is more complex than the pump core.
The standardized drawings of bead fork screws must be standardized, otherwise, their dimensions are inaccurate. After the later combination and installation, there are more complex factors. The results can be predicted that the injection molding materials must pass the material body compatibility verification, otherwise, the compatibility problem will happen, and the problem of screwing up and down will be over. The bead fork screw is the top priority. Generally, the base will aggravate the iron to feel it. If there is a problem with the heavy iron glue, it is equivalent to adding risk to the lipstick tube. In addition, the vibration in transportation will cause great trouble in degumming.
Main quality control index of a lipstick tube
The main control indicators include hand feels indicators, filling machine requirements, transportation vibration requirements, airtightness prevention, material compatibility, size matching, plastic tolerance and color in aluminum, production capacity, and filling volume to meet the declared value of products. Relationship between lipstick tube and material body lipstick material body is soft and hard, too soft, beads are not deep enough, and hold cannot hold the material body. As soon as guests apply lipstick, the lipstick meat will fall out. The material body is too hard to apply. Volatile material body. If the airtightness is not good, it is very easy to cause the material body to dry, and the whole product will fail.
Development and design of lipstick tube
Only based on understanding the reasons for various requirements can we design various test methods and standard various indicators. Newcomers must choose a mature bead fork screw design and complete the general bead fork screw design as soon as possible.
