Lipstick tube is the most complex and difficult of all cosmetic packaging

Lipstick tube is the most complex and difficult of all cosmetic packaging materials

First of all, we have to understand why lipstick tube is difficult to do and why there are so many requirements. Lipstick tube is composed of multiple components and functional packaging composed of different materials. From the material body, it is also divided into volatile and non-volatile (airtight / non-airtight), plus most of the filling is automatically filled by machines (pre-filling, post-filling, direct filling, etc.). Loading, including lipstick tube, is very complex, the combination of different parts, poor tolerance control, or unreasonable design, even if the lubricating oil is applied in a wrong way, it will cause shutdown or abnormal function, these errors are fatal.

ONE lipstick tube main functional components
Bead fork snail is the core component of lipstick tube, that is, bead, fork, screw, bead fork snail and lubricating oil constitute the core of lipstick tube, which is a bit like pump core, but it is more complex than pump core, and some manufacturers boast that oil-free bead fork screw design is not widely used at present.
 

 
Bead fork snail standardized drawings must be standardized, otherwise, their own size can not grasp, after assembly, more complex factors, the result can be expected that the injection molding material must pass the material compatibility verification, otherwise compatibility problems will occur. Screw up and screw down the problem is over, the bead fork snail is the most important thing.
The base is generally for the feel, but also aggravates the iron, heavy iron glue problems, which is tantamount to adding a risk in the lipstick tube, coupled with the vibration in transportation causing great trouble in degumming.

 

• Basic quality index. The main control indicators include handle index, filling machine requirements, transportation vibration requirements, anti-air tightness, material compatibility problems, size matching problems, aluminum plastic tolerance and color problems, production capacity problems, and filling volume to meet the declared value of the product.

 

• The relationship with the material body. Lipstick material has soft and hard, too soft, beads (cup) is not deep enough, HOLD does not live on the material body, guests wear lipstick on the lipstick meat out, the material body is too hard to apply, volatile material body (do not decolorize lipstick), if the air tightness is not good (lid and bottom match is not good), very easy to cause material body dry, the whole product failed.

THREE Development and design of lipstick tube

Only on the basis of understanding the reasons of various requirements can we design various test methods and standardize various indexes. the novice must choose the mature bead fork snail design and complete the general bead fork snail design as soon as possible.


FOUR How to choose the supplier of lipstick tube

Be sure to complete the evaluation of the supplier's bead fork snail design before selecting the supplier. You must not choose the supplier for the following reasons:

•  L'Or é al has also used it, (your material is different, your filling machine is also different)
•  this cheap
•  this supplier aluminum medium plastic channel is unstable
•  the assembly line is inexperienced or non-standard.
•  the easiest way to provide suitable bead fork snail drawings
