Analysis of the reasons for the inconsistency of mink lashes

Before introducing mink lashes, I would like to popularize the concept that the mink hair we used is natural and real mink hair, not synthetic, nor the hair of other animals hair.

The thickness of mink hair ranges from 0.10mm to 0.15mm, and even the hair on the same mink is not the same thickness. We also use human hair as a raw material for making false eyelashes, and human hair has the same problem.
So in order to solve this problem, we will first classify the thickness of mink hair according to an interval range. Such as 0.10-0.12mm and 0.13-0.15mm
However, due to the huge market demand for mink eyelashes, the highest quality mink wool raw materials are very scarce at present. In the past, the purchased quantity of a single batch was about a few hundred kilograms, but the current purchase quantity is only a few dozen kilograms. Due to the demand for raw materials for mink hair, it also stimulates the breeding of mink. But real fine mink hair is still in short supply.
Let’s start with a formal introduction to the three reasons for the inconsistency of mink lashes:

First of all, it is due to the difference in the thickness of mink hair. Because mink hair is the same as human hair, it is similar to a circle from the point of view of the section. Therefore, the combination of mink hairs of different thicknesses will produce very slight differences in appearance due to different lengths and thicknesses. This is the objective factor that causes the inconsistent appearance of mink hair, and often can not be completely avoided.
Because each batch of mink hair, due to seasonal factors, the breed of mink, and the body state of the marten itself, there will be different thicknesses of hair.
We can only think of it as a distinction, but it is impossible to pick out all the thicknesses of 0.10, 0.11, 0.12, 0.13, 0.14, 0.15mm, which is a heavy workload and requires a high cost of labor. Based on our monthly production of 100,000 pairs of eyelashes, this is an impossible task.
So we can only carry out rough screening and classification through the inner diameter micrometer during the quality inspection. The second is that in the eyelash curling tube, we usually roll several pairs of eyelashes onto a tube at the same time, and the force on the eyelashes is uneven in the process of operation. The operation procedure of each worker is the same, but different workers are slightly different in the subtle manipulation. This is another cause of eyelash inconsistency.

The third reason is that due to the different thickness of the single root, the degree of thermal deformation is different, the deformation degree of coarse material is small, and the deformation degree of fine material is large. At the same heating temperature, we will adjust it according to the external temperature in winter and summer.

In order to prevent batch quality problems, we have added quality inspection in each process. From the beginning of the raw materials into the factory, it is necessary to test the water absorption, gloss, coarseness, and other indicators of the raw materials, and then carry out the trial production of this batch of raw materials. If no problem is found in the production process of the sample. This batch of raw materials can be stored in storage, and the material production should be carried out in strict accordance with the principle of first-in-first-out.

At the same time, each eyelash should have a special corresponding code, corresponding to the production of abrasives and the corresponding drawings. When the production of this eyelash is started, the drawings, molds, and work orders of the second product are not allowed in the production operation area. Prevent any possible cross-cutting errors, especially similar products, which are geographically strictly zoned.
After the completion of each semi-finished process, the quality inspectors will compare the quality template, we will distinguish the product perfect status, product qualified status, product acceptable status, product rework status, product unqualified status. All unqualified products can no longer flow into the production area, directly judged as waste, and sent directly to the waste area, and destroyed after the end of production on the same day. Waste products are not allowed to flow out of the factory area.
In the final state of the finished product, we only have two areas of qualified products and non-conforming products. For non-conforming products, it will no longer be repaired and will be directly judged as scrap.
We will not send problematic products to customers. Our philosophy is that product safety is the first, quality is the second, and efficiency is the third.
Of course, we are not saying that we have not received any quality complaints, because judging from the appearance, there are still subjective factors and deviations. We can agree with our customers on common acceptable and enforceable standards. This is why we spend a lot of time and energy establishing quality control standards and quality files for every customer.
