Lipstick Tube is the most complex of all cosmetic packaging materials. The lipstick tube is a combination of multiple components. It is a functional packaging composed of different materials. From the material body, there are also volatile and non-volatile (air-tight/non-volatile) types. Airtight), and most of the filling is automatically filled by the machine (pre-filling, post-filling, direct filling, etc.), including the filling method of the lipstick tube, the combination of different parts, the tolerance control is not good, or the design is not Reasonable, even if the way of lubricating oil is wrong, it will cause downtime or malfunction.

product structure:

1. Product classification:

Divided by components: cover, bottom, middle beam core (medium beam, beads, fork and spiral), etc. The middle beam is generally made of aluminum, which has better hardness and metal texture after anodizing, and plastic injection molding is also used. shaped.

Bead inner diameter: 8.5mm, 8.6mm, 9mm, 9.8mm, 10mm, 11mm, 11.8mm, 12mm, etc.;

Number of beads: 4 ribs, 6 ribs, 8 ribs, etc.

According to product structure: traditional lipstick case, slim type, lipstick/lip gloss box, lip balm, vermicelli, lip oil, etc.

Filling method: bottom irrigation, top irrigation

2. Cover

Lipstick tube caps are generally aluminum caps, acrylic caps, ABS caps, etc.

3. Base

The base is generally made of acrylic or ABS plastic, and some use aluminum as the base material. Some suppliers also add heavy iron in order to increase the feel. However, the problem of heavy iron glue is equivalent to adding a risk to the lipstick tube. In addition, the vibration in the transportation will cause a quality accident in case of degumming, allowing customers to experience It's worse.

4. Middle beam core

The center beam core is the core component of the lipstick tube, which is equivalent to the heart of the product. Whether the lipstick tube product has a good customer experience, the basic function is in the experience of the center beam core. It carries the torsion of the entire lipstick tube product. , Smoothness, blocking force, insurance force, bead endurance and other functions.

Beaded snails generally have a double helix structure, and their pitch is long, and the travel distance of the bead after one rotation is large, so some users also call it a fast screw. The beaded snail is the core component of the lipstick tube. Beads, forks, spirals, beaded snails and lubricating oil constitute the core of the lipstick tube. The cup is the part of the mouthpiece that directly contacts the lipstick body. ) The travel track of the beads in a straight line, and the travel track of the Spiral beads in the upward spiral direction, cooperate with the fork to achieve the purpose of the rotation process and the upward movement of the beads.

The bead screw is a bit like a pump core, but it is more complicated than the pump core. Some manufacturers say the design of the lubricating-free bead screw is not widely used. The standardized drawings of bead snails must be standardized. Otherwise, you will not be able to grasp the size. After assembly later, there will be more complicated factors. As a result, it can be predicted that the injection molding material must pass the material compatibility verification, otherwise compatibility problems will occur. It is not good if you screw up and screw down. Beaded snails are the top priority.
