HCK 180 ton injection molding machine plastic hair comb making machine servo motor injection molding machine
The basic working principle of the injection molding machine is to heat and compress the plastic particles, so that they are melted and injected into the mold, and then cooled and cured to form the desired shape.
The specific steps include:
Feeding system:
The plastic pellets enter the machine through the hopper.
Heating system:
The plastic pellets are heated to a molten state in a heating drum.
Injection unit:
Molten plastic is injected into the mold through a screw or hydraulic system.
Cooling system:
The plastic in the mold is cured and formed after cooling.
Demoulding: The cooled finished product is removed from the mold by the ejection mechanism.
Injection Molding Features of Plastic Hair Combs Material Selection
Plastic hair combs usually use materials such as polyethylene (PE), polypropylene (PP), etc., which have good durability and cost-effectiveness.
Mold design:
Mold needs to be precisely designed to ensure that the tooth spacing, thickness, and shape of the comb match the desired needs.
Production efficiency:
The injection molding machine can achieve high-efficiency mass production and is suitable for large-scale manufacturing.
Quality control:
By adjusting the injection pressure, temperature, and cooling time, product quality can be optimized and defects can be reduced.
We are prefessional production base specialized in designing and manufacturing plastic injection machines and enjoy high reputation in the Plastic machinery industry.

Moulds can be costomized
Combs are known as tools for grooming human hair (see for example patent Reference 1).In such a comb, a line of roughly needle-shaped teeth protrudes from the main body.
As the material of the comb, it is known that there are various materials, but the comb that has been coated on the resin forming parts usually has a good handling.In particular, the comb formed by ABS resin is coated, the surface becomes smooth, and the friction with the hair is reduced.
In addition, such combs are thought to have the effect of discharging the human body as a ground wire against the static electricity trapped in the hair.
However, after the coating of the resin forming part, no coating is performed at the part of the junction with the electrode used for the coating when it is presented from the coating solution.
Therefore, the part of the contact with the electrode exposes the resin, or the burr formed when the peeling electrode is generated.In other words, the part of the junction with the electrode that does not perform the desired plating is the so-called non-plating part.
Because such a non-coating is not attractive, the coating has been applied to the area to make it smooth so that it will be the same color as the surrounding coating.
However, the coated part is easier to peel off than the coated part, immediately exposing the inner resin.This can lead to unsightly combs.
In addition, if the immediate part of the tooth as described above is in the vicinity of the tooth, when the comb is used to peel the part will contact with the hair.
May cause damage to the hair.In addition, due to the low conductivity of the non-plated part, the static electricity trapped in the hair is difficult to diffuse through the human body to ground.
