Product definition
Lipstick tubes are the most complex of all cosmetic packaging materials. Lipstick tubes are composed of multiple components and functional packaging composed of different materials. In terms of the material body, they are divided into volatile and non-volatile types (airtight/non-airtight). In addition, most of the filling is done automatically by machines (front filling, back filling, direct filling, etc.). Including the filling method of the lipstick tube, the combination of different parts, poor tolerance control, or unreasonable design, even if there is an error in the way the lubricant is applied, it will cause downtime or malfunction.
Manufacturing process
1. Basic materials
Lipstick tubes are divided into full plastic lipstick tubes, aluminum-plastic composite tubes, etc. The commonly used plastic materials are PC, ABS, PMMA, ABS+SAN, SAN, PCTA, PP, etc., while aluminum models are commonly 1070, 5657, etc. Some users also use materials such as zinc alloy and sheepskin as lipstick tube accessories to indicate that the product's temperament matches its brand tone.
2. Molding process
The plastic material of the lipstick tube is mainly injection molded, such as the cover, base, and related accessories inside the middle bundle core.
3. Surface treatment
There are many surface treatment processes available for lipstick tubes. For plastic accessories, surface treatment processes such as spraying, electroplating, evaporation, laser engraving, and inlay can be used, while aluminum products can be treated with oxidation electroplating, anodizing, and other processes.
4. Graphic printing
The lid and base of lipstick tubes can be processed with graphic and textual information using techniques such as screen printing, hot stamping/silver, transfer printing, heat transfer printing, and water transfer printing according to user needs.
product mix
1. Product Category:
Divided by components: cover, bottom, middle bundle core (middle bundle, beads, fork, and spiral), etc. Among them, the middle bundle is generally made of aluminum products, which have better hardness and metallic texture after anodizing treatment. There are also those made of plastic material injection molding.
Bead inner diameter: 8.5mm, 8.6mm, 9mm, 9.8mm, 10mm, 11mm, 11.8mm, 12mm, etc;
Bead ribs: 4 ribs, 6 ribs, 8 ribs, etc
According to product structure: traditional lipstick shell box, slender type, lipstick/lipstick box, lipstick, vermicelli, lip oil, etc.
Filling method: Bottom pouring, Top direct pouring
2. Cover up
Lipstick tube covers are usually made of aluminum, acrylic, ABS, or other materials.
3. Base
The base is usually made of acrylic or ABS plastic, but there are also aluminum substrates. Some suppliers also add iron inside to increase the feel, but if there is a problem with the iron glue, it is equivalent to adding a risk inside the lipstick tube. Coupled with the vibration during transportation, if it comes off, it will cause a quality accident, making the customer experience worse.
4. Mid bundle core
The middle bundle core is the core component of the lipstick tube, equivalent to the heart of the product. Whether the lipstick tube product has a good customer experience or not, the basic functions are based on the experience of the middle bundle core. It carries the torque, smoothness, blocking force, safety force, bead bearing force and other functions of the entire lipstick tube product.
The bead fork screw is generally a double helix structure with a long pitch, and the travel distance of the bead after one rotation is relatively large. Therefore, some users also refer to it as a fast screw. The bead fork screw is the core component of the lipstick tube, consisting of beads, forks, spirals, bead fork screws, and lubricating oil. The bead cup is the part of the mouth cup that directly contacts the lipstick meat body. The fork bead travels in a straight line, and the spiral bead travels in a spiral upward direction, cooperating with the fork to achieve the purpose of rotation and upward movement of the bead.
The bead fork screw is somewhat similar to a pump core, but more complex than the pump core. Some manufacturers also claim that the bead fork screw design does not require lubricating oil, but it is not widely used at present. The standardized drawing of the bead fork screw must be standardized, otherwise, the size cannot be grasped by oneself, and after assembly, there will be more complex factors. The result can be expected that the injection molding material must pass the compatibility verification of the material body, otherwise compatibility problems may occur, and it is not good to have problems when turning it up and down. The bead fork screw is of utmost importance.
Cosmetics application
Lipstick tube, as its name implies, is applied to lipstick and lipstick products,
But with the rise of lipstick products such as lip sticks, lip gloss, and lip gloss,
Many packaging factories use the packaging structure of lipstick tubes
Fine tuned and formed a full range of applications,
We will provide a detailed classification and description in the future.
Procurement precautions
Choose a lipstick tube supplier
Before selecting a supplier, it is necessary to complete an evaluation of the supplier's pearl fork screw design. Under no circumstances should you choose a supplier for the following reasons: L'Oreal has also used it; (Your ingredients are different, and your filling machine is also different); This cheap supplier's aluminum medium plastic channel is unstable; The assembly line lacks experience or is not standardized; Praising the big bull. The simplest way is for the supplier to be mysterious if they cannot provide suitable drawings for the bead fork screw.
2. Quality control indicators for lipstick tubes
There are tactile indicators, filling machine requirements, transportation vibration requirements, anti air tightness, material compatibility issues, size compatibility issues, aluminum plastic tolerance and color issues, production capacity issues, and filling volume requirements to meet the product's declared value.
3. The risk of using aluminum lipstick tubes
The process limitations in the stretching and cutting of aluminum products, if the structure of the product is not smoothed, may pose potential safety risks to consumers! Sharp edge testing equipment that meets the requirements of 16 CFR 1500.49 in the United States federal regulations can be used, and pressure-sensitive insulation high-temperature resistant tape that meets the MIL-I-23594B (1971) standard can be selected for testing to evaluate the risk of the product.
