The plastic bottles produced by different processes are different. This article mainly introduces the comparison of the process principles, advantages and disadvantages, and the differences between the advantages and disadvantages of the squeezing molding molding and injection blow molding molding, so that readers have a more intuitive understanding of the plastic bottle molding process.

there are to make a bottle. The Answer to Which Kind of Technology Should Be chosen Depends on the Characteristics required, as mentioned in this article – What are the differences between injection and extrusion blow molding? What are their pros and cons in actual applications?

Note the quality of the body of 100ml lactic acid bacteria bottle.
The formation of molding has now developed into the first production method of plastic bottles. The advantage is that the cost of molds and oral molds is low, and the mold materials are rich; rich in product types; large -scale, complex hollow products; production efficiency and automation level high. The disadvantages include a certain restriction on the shape of the product; the wall thickness is controlled to be difficult; the size accuracy is low.

Drawing on the long -established glass container blowing process, putting the plastic embryo that is squeezed out or injected with a sticky stateIn the mold, the type of embryo is swollen by compressed air to make it close to the wall of the cavity. This is the hollow blow molding process. 采用挤吹和注吹工艺生产100ml乳酸菌瓶身质量对比。
Squeeze out the forming, injection blowing molding, and stretching and molding. Squeeze out the molding molding, squeeze out the melting material from the extruded device, place it in the squeezing embryo in the blow molding mold for bloating, cooling the mold and removing the product after cooling; The embryo, then transfer to the blow molding mold to swell. After the cooling is cooled, the mold is removed and removed; , Blowing the air to cool down the cooling, and finally remove the product.

] Squeezing out and blowing molding is the biggest, and it is also a type of blow molding molding method earlier. It is suitable for ,

, PVC

, thermoplastic engineering plastic and thermoplastic elastic body, as well Blowing molding is mainly used to produce packaging containers, storage tanks and other industrial parts. 挤出吹塑工艺图。 \u0026 nbsp;

The first is that the material squeeze out the tube -shaped embryo after the squeezing machine is melted and plasticized; the type of the type of the type reaches the predetermined length, and the section is interceptedPlastic embryos are placed in the blow molding mold while it is hot, closed and clamped the mold; then, the compressed air that blows into the type of embryo through the blowing mouth, the shape of the accurate swelling and forming cavity is opened. Products. \u0026 nbsp; The production cost of the container is low; the capacity can be produced multi-layer, thin-walled and complex container and other capacity is from 1ml-3000L

. However, flying edges during the production process, the size of the snail tooth is unstable, and the sealability is poor; the degree of automation is poor; the product cycle is long and the production efficiency is low.

\u0026 nbsp;

, but With the two major technologies of the type of blank wall thickness controller and non -core design, the molding process has obvious advantages in the production of thin -walled products and complicated tubes or bottle body.

\u0026 nbsp;

type blank wall thickness controller In the forming stage of the type, according to the bloating ratio of various parts, the wall thickness distribution of the type of billet can be adjusted, and the swelling molding is uniform.

Taking the automotive industry accessories as an example, the car door panel, top plate, and the common seamless door handles produced by extruded plastic molding processes are thin and thin but high, reducing fuel consumption and reducing the manufacturing cost. Therefore, more and more automobile accessories use squeezing and blowing molding processes, such as the production of fuel tanks and various pipelines.

\u0026 nbsp;

The design of the non -type without core is in the Household daily chemicals are shining. Taking the common Da Rong accumulation of the bottle as an example, due to the large bottle body and heavy quality, customers will prefer to choose products with handle. The coreless design does not need to consider the problem of the departure card. It can produce containers with the structure of the handle structure, and even the complicated foldable container.

\u0026 nbsp;

\u0026 nbsp;

injection Blowing molding is a combination of injection molding and blowing molding molding. First of all, the injection injects the melt into the molding mold with the pneumatic core tube to form a bottomed embryo. Blowing in the mold; after that, the blow molding mold introduces the compressed air from the core of the core to the interior of the embryo. The type embryo is closely fitted with the blowstorm cavity under the action of the air pressure. Xinchen Extrusion , dropped the product from the core rod or sent it directly to the packaging position to enter the next cycle process to produce.

\u0026 nbsp;

Injecting blow molding molding process The degree of automation and production efficiency is high; the product has no splicing line, the bottom strength is high, the wall thickness is uniform, and the size of the mouth is high and precise; no corner waste or flying edges, and the sewing line is fine; Mouth container. The disadvantage is that it is impossible to process products with too complicated shapes; container capacity is limited to 5ml-500ml

MSZ The model is an example. The requirements of uniform distribution, the three -site rotation lifting system can be performed 120

Rap the rotation, so that the three stations of injection molding, blowing and molding can be continuously continuous Flowing.

\u0026 nbsp; In addition, due to the use of hydraulic driving drivers The link structure, the model’s positioning is more accurate, the maintenance cost is lower, and it is faster and stable. The departure station with the conveyor belt to achieve automatic molding, automatic counting and automatic packaging, which can meet the strict requirements in the field of pharmaceutical and health.

100ml lactic acid bacteria bottle as a reference, comparison It can be found that the bottom of the lactic acid bacteria bottle with squeezing and blowing molding has flying edges and cut marks at the bottom of the bottle. There is a certain risk of leakage; and the bottom of the lactic acid bacteria bottle with blowing molding is smooth, the wall of the bottle body is uniform, the position of the bottle mouth is accurate, the intensity is high, and there is no shrinkage.

\u0026 nbsp;

from this can be found When producing the same product, the former has innate advantages, without flying edges, no waste, and accurate size, and then operate with three stations at the same time without gap; cooperate with the transportation belt, the detection equipment can directly enter the packaging. The level of service is extremely high. Therefore, within the scope of the packaging of the packaging, the use of injection blowing molding process into a bottle can improve production efficiency and reduce production costs.
