Lipstick tubes are the most complicated and difficult of all cosmetic packaging materials. First of all, we must understand why lipstick tubes are difficult to handle and why there are so many requirements. Lipstick tubes are composed of multiple components. Functional packaging composed of different materials, from In terms of material body, it can be divided into volatile type and non-volatile type (airtight/non-airtight), plus most of the filling is automatically filled by machines (front filling, back filling, direct filling, etc.), including lipstick The loading of the tube is very complicated, the combination of different parts, the tolerance control is not good, or the design is unreasonable. Even if the way of lubricating oil is wrong, it will cause shutdown or abnormal function. These mistakes are fatal.
The Main Functional Parts Of The Lipstick Tube
The bead screw is the core component of the Lipstick Tube, that is, the bead, the fork, the spiral, the bead screw and the lubricating oil constitute the core of the lipstick tube. It is a bit like a pump core, but it is more complicated than the pump core. Some manufacturers brag that they are free of lubricating oil beads. Fork screw design, but currently not widely used.
The standardized drawing of the bead fork screw must be standardized, otherwise, the size cannot be grasped accurately, and after assembly later, there will be more complicated factors. Haha, the result can be expected. The injection molding material must pass the compatibility verification of the material body, otherwise compatibility will occur The problem, if there is a problem with the screw up and down, it will be over, and the bead fork screw is the top priority.
The base is generally made of heavy iron for the feel of the hand. If there is a problem with the heavy iron glue, it is equivalent to adding a risk to the inside of the lipstick tube. Coupled with the vibration during transportation, it will cause a lot of trouble to degumming inside.
Quality Control Indicators Of Lipstick Tubes
1. Basic Quality Indicators
The main control indicators include hand feel index, filling machine requirements, transportation vibration requirements, airtightness prevention, material compatibility issues, size mutual matching issues, aluminum-in-plastic tolerance and color issues, production capacity issues, and The filling volume should meet the declared value of the product.
2. The Relationship with The Material Body
Lipstick material body has hardness, too soft, the bead (cup) is not deep enough, HOLD cannot hold the material body, the lipstick flesh will fall out as soon as the customer applies lipstick, the material body is too hard to apply, volatile material body (does not fade Lipstick), if the airtightness is not good (the lid and the bottom are not well matched), it is very easy to cause the material to dry out, and the entire 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 the mature bead screw design and complete the general bead screw design as soon as possible.
How To Choose A Supplier Of Lipstick Tube
Be sure to complete the evaluation of the supplier's bead screw design before selecting a supplier. Never choose a supplier for the following reasons:
1. L'Oreal has also used it, (your material is different, your filling machine is also different)
2. This one is cheap
3. The channel of this supplier is not stable
4. The assembly line has no experience or is not standardized
5. A braggart. The easiest way is for suppliers who can’t provide suitable bead screw drawings to ask for help.
The common quality problems of lipstick tubes include material problems, process problems, and assembly problems. The problems after delivery are actually doomed during development, and 70% of the tragedies are doomed during development. Therefore, lipstick tubes are not easy to make, and experienced suppliers must be selected. It's not just a few parts and a few samples, just get mass production approval. Makeup is difficult, and I can't finish it in a sentence or two, but first I have to understand what is important, what is not important, what must be considered first, and what is the reason for what is required? This is the root. If you encounter specific problems, you can communicate in the Youpin product community.
