Compression Moulding in plastic industry: Recent Episodes

View Details

Plastic cap compression moulding machine will be touched and used by everyone. Generally, we are most concerned about whether the small plastic cap can really prevent leakage and protect the liquid or other things in the container from spilling. come out.

1. There is an annular anti-leak ring on the inner wall of the top end of the general plastic cover; there is also a common plastic barrel cover to match the inner cover, so there is no need to design a leak-proof ring;

2. The lower end of the plastic cover is connected to an anti-theft ring by a tension rib;

3. At the same time, a plurality of sheet-shaped rotary pull wings are evenly distributed on the inner wall of the anti-theft ring; the plastic bucket cover designed by the method has the advantages of firm sealing, leakproof and anti-theft performance, safe and convenient use, and can effectively prevent the liquid in the container from being Subject to external pollution, it can ensure that various liquid product packaging meets national safety standards. So the plastic bottle cap can be used with confidence, it will help us to preserve the liquid in the container from other factors.

Plastic cap compression moulding machine, because the bottle cap is a tight part of the beverage packaging industry, the desperate consumption of market demand changes, will directly affect the market demand for caps, and the development of the beverage industry, the more demanding the product packaging High, followed by the demand for cap products. And the bottle cap products are in the key position of the beverage packaging industry, so the growth trend of the beverage industry will directly affect the demand for cap products. In recent years, the demand for the bottle cap product market has been stable and has a growing trend. However, the change in the packaging material used makes the change in the layout of the bottle cap product; the group will increase the utilization ratio of the cap. Although the aluminum cover is partially replaced by a plastic cover, it is used in wine and functional beverages, and the demand is stable, while the demand ratio of the claw cover is greatly changed.

The basic function of the plastic bottle cap molding machine shell

According to plastic bottle cap molding machine manufacturers,the plastic shell mold is a manufacturing tool that can press and shape the plastic shell of the product under the high-strength pressure according to the requirements of the designed drawings, and the upper mold and the lower mold of the mold and the use therebetween The design and fabrication of the cavity for filling the plastic pressed casing directly determines the quality level of the produced plastic casing, including whether the thickness is uniform and whether it is easy to perforate.

The basic role of the plastic shell mold is that its own standards directly determine the quality of plastic products. It is necessary to give full play to the basic role of the mold: on the one hand, it is necessary to start from the production of the mold, confirm the physical properties and chemical properties of the plastic of the precise shape of the plastic shell to be produced, so that it can be targeted in the process of making the mold. Corresponding cavity shape, cavity surface finish, gate and related slots, and finally control some unnecessary bubbles, silver streaks and dents within an acceptable range; on the other hand, from the use of the mold Starting, simple operation, high efficiency and intelligence are the optimal requirements of the mold.

If you can achieve the optimal operation parameters, of course, you can play the role of the mold to a greater extent, such as the control and application of clamping and parting. To a large extent, it embodies the designer's wisdom. In the process of clamping, in order to save manual labor, more automatic ejection structure should be adopted, and for the production of a large number of plastic casings, the parting should be reduced, thereby improving production efficiency. .
