Lipstick tubes are the most complicated and most difficult of all cosmetic packaging materials. First of all, we must understand why lipstick tubes are difficult to make and why there are so many requirements. Lipstick tubes are a combination of multiple components and functional packaging composed of different materials. In terms of material, there are volatile and non-volatile (air-tight/non-air-tight), and most of the filling is automatic filling (pre-filling, post-filling, direct filling, etc.), including lipstick The loading of the tube is very complicated, the combination of different parts, poor tolerance control, or unreasonable design, even if the way of lubricating oil is wrong, it will cause downtime or malfunction. These errors are fatal.

The main functional parts of the lipstick tube

The beaded snail is the core component of the lipstick tube. Beads, forks, spirals, beaded snails and lubricating oil constitute the core of the lipstick tube. It is a bit like a pump core, but it is more complicated than a pump core. Some manufacturers brag about no lubricant beads. Fork screw design, but currently not widely used.

The standardized drawings of the bead snails must be standardized, otherwise, you will not be able to grasp the size, and there will be more complicated factors after the subsequent assembly. As a result, it can be predicted that the injection molding material must pass the compatibility verification of the material, otherwise compatibility problems will occur, and the problem will be over if the screw is screwed up and screwed down. The bead screw is the top priority. The base is generally for the hand feel, and it also adds weight to the iron. The problem of heavy iron glue is equivalent to adding a risk to the lipstick tube. In addition, the vibration in the transportation causes the trouble of degumming inside.

The main quality control index of lipstick tube

The main control indicators are hand-feel indicators, filling machine requirements, transportation vibration requirements, airtightness prevention, material compatibility issues, size interoperability issues, aluminum-plastic tolerance and color issues, productivity issues, and The filling volume must meet the product's declared value. The relationship between the lipstick tube and the material. The lipstick material has hardness, too soft, and the cup is not deep enough. HOLD does not hold the material. The customer will fall out of the lipstick as soon as the lipstick is applied. The material is too hard to apply. , Volatile material (non-bleaching lipstick), if the air tightness is not good (the lid and the bottom are not well matched), it is very easy to cause the material to dry, and the whole product will fail.

Development and design of lipstick tube

Only on the basis of understanding the reasons for various requirements can we design various test methods and standardize various indicators. Novices must choose mature bead snail designs and complete general bead snail designs as soon as possible.

Common quality problems of lipstick tubes include material problems, process problems, and assembly problems. The problems that occur after delivery are actually destined for tragedies during development, and 70% of tragedies are destined for development. Therefore, the lipstick tube is not easy to make. When the cosmetics manufacturer chooses to purchase the packaging supplier, it is best to choose an experienced supplier like Shantou Qicheng Packaging Products.
