The Reliable Jilian Pet Preform Manufacturers

May 22, 2019 by preform nicole  

The first stage of bottle manufacturing is stretch blow molding. The polyester is heated and placed in a Pet Preform Mould in which the polyester assumes the shape of a slender tube. (The process by which PET is pressed into the mold is called injection molding.) The polyester tube, now called the parison, is then transferred to a second bottle mold. A thin steel bar called a mandrel slides inside the parison, where it fills the parison with high-pressure air, and the stretch blow begins: the parison is blown and stretched into the mold due to compressed air, heat and pressure, Presents the shape of the bottle. In order to ensure a consistent flat shape of the bottom of the bottle, the individual components of the PET are simultaneously attached to the bottle during the blow molding process.

The mold must be cooled relatively quickly so that the newly formed part is properly set. There are several direct and indirect cooling methods that effectively cool the mold and PET. Water can flow through the pipes around the mold, indirectly cooling the mold and PET. Direct methods include the use of compressed air or carbon dioxide directly on the mold and PET.

Once the bottle (or, in continuous production, the bottle) is cooled and solidified, it can be removed from the mold. If a continuous molding process is used, the bottles need to be separated by trimming the PET between them. If a non-continuous process is used, sometimes excess PET will penetrate the mold during the manufacturing process and needs to be trimmed. After the bottle is removed from the mold and the excess PET is removed, the bottle can be transported.

Pet Preform Mould Technology Should Be Improved

May 16, 2019 by preform nicole  

We all know that when the pet bottle appeared, it was widely recognized and used in various industries. Whether it was in industry, manufacturing, technology or food, slowly over the past few years, everyone’s products for PET materials broke out. As a matter of doubt, the Pet Preform Mould market is slowly being impacted by other materials.

Especially for food packaging, there are many forms and materials, pet, glass, carton, canned food, packaging bags, etc.; the variety of various packaging forms greatly meet the food needs for packaging; The demand for pet bottles is naturally less. Now, no matter what kind of packaging, as long as the cost is low, the style is exquisite, and the food packaging that is favored by ordinary consumers can obtain lasting vitality in the market.

The pet bottle needs to be upgraded again, and it needs to be upgraded to solve its own shortcomings. It is recognized by everyone, and it has a certain weight in the market. It is not difficult to get a new favorite.

       As people's awareness of environmental protection continues to increase, pet preform manufacturers produce Pet Preform Mould with a large amount of water. The sound of resisting bottled water is not overwhelming in the near future. More and more, the voices of Europe and the United States are higher, and the cost of PET bottles will be reduced at a certain level. Instead, the rest of the packaging materials are used, and if there is an expert's idea, glass bottles are used to package the water.

After discussing the trade data of PET bottles in the previous period and the operation status of PET bottles, the future prospects of PET bottles are optimistic, but at the moment, the development of many small and medium-sized pet preform manufacturers in China faces many challenges.

PET bottle green packaging materials advocate the use of raw materials, it is possible to use the same raw materials, can be used to coexist with raw materials, despite the simple structure, simple reincarnation of raw materials. At the same time, despite the reduction in the amount of waste generated, the development trend of lightweight packaging film is revealed.

Jilian Plastic Mold Pet Preform Manufacturers Is Trustworthy

The gating system is one of the most important issues in the design of injection molded preforms. The gating system is a complete conveying path that directs the plastic melt from the injection molding machine nozzle to the mold cavity. It has the functions of mass transfer, pressure holding and heat transfer. It has a decisive influence on the quality of plastic parts. Whether the design is reasonable, affecting the overall structure of the Pet Preform Mould and its ease of operation.

The function of the gating system is to fill the plastic melt smoothly into the depth of the cavity to obtain a plastic product with a clear outline and excellent internal quality. Therefore, in the filling process, rapid order is required, pressure loss is small, heat loss is small, exhaust conditions are good, and the pouring system is easy to separate or cut from the product.
Ordinary runner casting system

The common sprue system, also known as the sprue system or the gating system, is the necessary passage for molten plastic from the injection nozzle to the cavity. The runner system includes a main runner, a runner, a gate, and the like.

Mainstream road

The main channel is part of the channel that connects the machine nozzle to the inlet of the branch channel, which is the first place where plastic enters the cavity of the pet preform mold. It can be understood as the flow path of molten plastic from the nozzle of the injection molding machine to the bypass.

Its size and size are closely related to plastic flow rate and fill time. Too much will result in too much cold material being recovered, increased cooling time, and increased enclosed air. It is easy to generate bubbles and loose tissue, and it is easy to generate overcurrent and insufficient cooling;

If the flow path is too small, heat loss increases, fluidity decreases, and injection pressure increases, resulting in difficulty in molding. Typically, the main runner is made into a separate runner sleeve that is placed on the parent template. However, there are some exceptions. Due to the low requirements, some small pet preform molds can be used to open the main channel directly on the parent template without the use of a sprue bushing.

The Preferred Pet Preform Manufacturers

May 5, 2019 by preform nicole  

 Food Pet Preform Mould are round in shape and have a square shape and an elliptical shape. The circular bottle body has a large application amount, and is characterized by uniform wall thickness, high external force resistance, low production cost, and low utilization rate of effective area during storage or transportation. The square bottle has a high effective area utilization and good stability, but it is more prone to bottle expansion and deformation.
    Why are the shapes of PET bottles in different foods different, but the shape of cans is the same? Because the cans are cold drawn and stretched, the round shape is very easy to make a deep drawing design. Other shapes are defective. PET bottles are injection molded or blow molded, and there is no requirement for shape, as long as it is easy to demould.
    From the aspect of production equipment, PET PET bottles are produced by injection blow molding equipment. When molding, the bottle mouth is first injection molded, thus ensuring the dimensional accuracy of the bottle mouth and thread parts, and then blowing the bottle body. The molding method of the device ensures a good sealing performance between the bottle mouth and the bottle cap.
    Food PET bottles are packaged in polystyrene (PS) bottles in terms of the variety of raw materials for bottles. Polystyrene is a non-crystalline resin material. Although it has good transparency, it has high brittleness, low strength, and raw materials. The molecule contains a benzene ring, which is not suitable for pharmaceutical packaging; it has a polycarbonate bottle (PC), which has high transparency and strength, but the price is relatively high;

    Polyester bottle (PET), which is used in pharmaceutical packaging, has high transparency, high strength, good moisture and gas barrier properties, and is widely used in pharmaceutical packaging;
    Polypropylene bottle (PP), the raw material of this bottle is high crystallinity PET, the molecules are arranged neatly and tightly, and the molecular force is strong. The reaction is strong in tensile strength, high rigidity, good gloss and good heat resistance. However, the flexibility and transparency are poor, and the amount of the drug package is large;
    High-density polyethylene (HDPE) bottle, which is crystalline PET, has good impact strength, good chemical resistance, good environmental stress resistance, and relatively low price. It is a bottle type with a very large amount of pharmaceutical packaging. First, its application has exceeded 1 billion.
    Therefore, we have learned from various aspects that the shape of food PET bottles is diverse for a reason.
    Jilian Plastic Mould is a Pet Preform Manufacturers that is favored in the market. We have various kinds of pet bottles, and also provide equipment for various products. Welcome customers who have needs to contact us. 

Pet Preform Mould Design Details Analysis

April 28, 2019 by preform nicole  

Change the surface shape of the pet bottle, such as the pet bottle body is relatively thin, increase the circumferential groove or rib of the surface of the pet bottle, can improve the rigidity and bending resistance of the pet bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the pet bottle under long-term load.

Analysis of the design details of the pet bottle:
The design of the pet bottle mouth should focus on how to make the pet bottle mouth better fit the lid and sealer. The bottom of the pet bottle is the weak part of the pet bottle mechanical function. Therefore, the bottom of the pet bottle is generally designed to be concave; the corners of the pet bottle and the concave portion are excessively curved. In order to facilitate the stacking of the pet bottle, it is not easy to increase the stacking code of the pet bottle, and the inner part of the pet bottle should be designed with a groove. For the corner of the rectangular pet bottle, it is necessary to support most of the load of the pet bottle, so locally increasing the wall thickness of the pet bottle is beneficial to further strengthen the rigidity and load resistance of the pet bottle. Therefore, in order to ensure the rigidity of the pet bottle, in addition to selecting a material with a relatively high hardness, the shape of the pet bottle is designed to enhance the rigidity and load resistance of the pet bottle.
1. In the process of blow molding, the tube blanking is gradually formed into the place where the Pet Preform Mould is first contacted, which is the part that tends to cool and harden first. Therefore, the wall thickness of this part also needs to be larger. The edge and the corner portion are the portions of the main tube that are blow molded to contact the pet preform mold, so the wall thickness of the portion is small. Therefore, the edges and horns of the pet bottle should be designed to be rounded. 2. When the surface of the pet bottle is labeled, the labeling surface should be flat. A "frame" can be designed on the surface of the pet bottle to position the label correctly without moving.
3, the printing surface of the pet bottle is the most concentrated part of the consumer's attention. Therefore, the printing surface should be flat and continuous; if the pet bottle contains handles, grooves, ribs, etc., the design should be careful not to cause inconvenience to the printing operation. The oval pet bottle has a high hardness, but the manufacturing cost of the pet preform mold is also high. In addition, when designing a squeeze PET bottle, if the material is high density polyethylene PE or polypropylene PP, the cross section of the pet bottle should be rectangular or oval, for low density polyethylene or other flexible pet bottles, Its cross section is preferably a circle. This facilitates the extrusion of the contents from the pet bottle. The pet parts used in conjunction with the pet bottle mouth are mainly caps and seals.
Most pets have notch sensitivity. The pet bottle is easily cracked and cracked at the sharp corners, the roots of the mouth threads, the neck, etc., so these parts should be designed to be rounded.

As a professional Pet Preform Manufacturers, Jilian Mould can effectively deal with the problems in the production process of pet products and bring satisfactory products to the vast number of consumers, so what are you still hesitating? A professional pet preform manufacturer is at your side, so let us know.
