According to the components: cover, bottom, middle bundle core (middle bundle, beads, fork and spiral), etc., wherein the middle bundle is generally aluminum, which has better hardness and metal texture after anode treatment, and also uses plastic material for injection molding.
Bead inner diameter: 8.5mm, 8.6mm, 9mm, 9.8mm, 10mm, 11mm, 11.8mm, 12mm, etc.; number of beads ribs: 4 ribs, 6 ribs and 8 ribs, etc.
According to the product structure: traditional lipstick shell box, slim type, lipstick / lip gloss box, lip balm, noodles, lip oil and so on.
Filling method: bottom pouring, top positive filling
The lipstick caps are generally aluminum caps or acrylic caps, ABS caps, and the like.
3, the base
The base is generally made of acrylic or ABS plastic, and is also made of aluminum. In addition, some suppliers add iron to the inside, but the problem of heavy iron glue is equal to adding a risk to the lipstick tube. In addition, the vibration on the transportation will form a quality accident and let the customer experience. Even worse.
4, the core of the core
The middle core is the core component of the lipstick tube, which is equivalent to the heart part of the product. Whether the lipstick tube product has a good customer experience, the basic function is in the experience of the middle core, which carries the torque of the entire lipstick tube product. , smoothness, resistance, insurance, and the ability of the beads to withstand.
The bead snail is generally a double-helical structure, and its pitch is long. The distance of the bead is large after one rotation, so the user also calls it a quick snail. The bead snail is the core component of the lipstick tube. The beads, forks, spirals, bead snails and lubricating oil form the core of the lipstick tube. The cup is the part of the cup that directly contacts the lipstick meat body. The fork (fork) The traveling track of the beads in the straight line direction, the traveling track of the spiral (Spiral) beads in the spiral rising direction, cooperates with the fork to achieve the purpose of the rotation process and the upward movement of the beads.
The bead snail is a bit like a pump core, but it is more complicated than the pump core. Some manufacturers say that the snail-free snail design is not widely used. The standard drawing of the beaded snail must be standardized. Otherwise, the size of the snail is not accurate. After the assembly, there are more complicated factors. The result can be predicted. The injection molding material must be verified by the compatibility of the material, otherwise the compatibility problem will occur. It’s not good to spin up and spin down. The fork snail is the top priority.
