Why Is the Production of Lipstick Tubes So Complicated?

Custom lipstick shell is the most complex and the most difficult of all cosmetic packaging materials. You must understand why lipstick tubes are so demanding.

The lipstick tube is a combination of multiple components. The functional packaging composed of different materials is divided into volatile and non-volatile types (airtight / non-airtight). Most of the filling is a machine. Automatic filling (front filling / backfilling / direct filling, etc.), including the loading of lipstick tubes, is very complicated, the combination of different parts, poor tolerance control, or unreasonable design, even if the lubricant is applied Errors can cause downtime or malfunctions. These errors are fatal

The main functional parts of the lipstick tube:

The bead screw is the core part of the lipstick tube, that is, the beads, fork, spiral, bead screw and lubricating oil form the core of the lipstick tube. It is a bit like a pump core, but it is more complicated than the pump core. Cross screw design, but currently not widely used.

The standardized drawing of the bead fork screw must be standardized, otherwise, its own size is not accurate. After the assembly, there are more complicated factors. The problem is that it is over when the problem is turned up and down. The bead snail is the top priority.

The base usually adds heavy iron for hand feel. The problem of heavy iron glue is equivalent to adding risk to the lipstick tube. In addition, the vibration of transportation causes the trouble of degumming inside.

Lipstick quality control indicators:

The main control indicators are hand-feel indicators, filling machine requirements, transportation vibration requirements, anti-airtightness, material compatibility problems, size inter-matching problems, aluminum plastics tolerance and color problems, production capacity problems, The filling volume should meet the declared value of the product.

The relationship between the lipstick tube and the body:

Lipstick material has a soft hardness, too soft, the cup is not deep enough, HOLD can't hold the material body, the customer will drop the lipstick meat as soon as the lipstick is applied, the material body is too hard to apply, volatile material Bleaching lipstick), if the airtightness is not good (the lid and bottom are not well matched), it is very easy to cause the material to dry, and the entire product fails.

Lipstick tube development and design:

Only on the basis of understanding the reasons of various requirements, can we design various test methods, standardize various indicators, novices must choose mature bead snail design, and complete the universal bead snail design as soon as possible.

Sum up:

The common quality problems of lipstick tubes include material problems, process problems, and assembly problems. The problem after delivery is that the tragedy is destined at the time of development, 70% of the tragedy is destined at the time of development, so lipstick tubes are not easy to do, and you must choose an experienced supplier. It is not necessary to get a few parts to install a few samples, just to obtain mass production approval. Make-up is difficult, one sentence or two can't be finished, but you must first understand what is important, which is not important, which must be considered first, and what are the reasons for the requirements? These must be considered. We are the lipstick shell supplier, if you are interested in our products, please feel free to contact us.
