Jilian Mold 5 Gallons Pet Preforms Cheap And Beautiful

PET is a polyester and is an abbreviation for polyethylene terephthalate. PET materials are commonly used in the injection molding of Pet Bottle Preform, such as mineral water bottles, Coca-Cola bottles, juice bottles, and the like.

Characteristics of PET raw materials
 Excellent transparency, over 90%, excellent surface gloss and glassy appearance.
Good aroma and air tightness.
 Excellent chemical resistance. Almost all organic drugs are resistant.
 Good hygiene, PDA certification (the largest chemical laboratory in the United States).
 No toxic gases are produced when burning.
 Excellent strength properties and can be further improved by biaxial stretching.
Why do you need to dry the PET resin before the pet bottle preform is injection molded?
1. Remove moisture from PET material before injection molding
Because PET materials have a certain water absorption, they absorb a lot of water during transportation, storage and use. Excessive water content in PET materials can affect production as follows:

AA (acetaldehyde) acetaldehyde increased. The smell of the beverage bottle makes the drink tasteful (but has little effect on the human body)
IV (intrinsic viscosity) viscosity decreases. It has an effect on the pressure resistance of the beverage bottle and is easily broken. (mainly caused by hydrolytic degradation of PET)
2. Prepare PET high temperature preparation into injection molding machine for shear plasticization
Water absorption characteristics of PET
The moisture content of the raw material particles is usually from 0.1 to 0.3% (1000 to 3000 ppm).

PET moisture absorption

The main points of PET drying
Dry set temperature 165-175 ° C

Problems In The Production Of Pet Bottle Preforms

Blow molding products are widely used in all walks of life, containers, films, beverage bottles, toys... can be said to have been integrated into our lives. A summary of the quality problems that are prone to blow molding products for discussion:
1. The longitudinal wall thickness of the blow molded product is not uniform:
Causes: 1 The bottle of the pet bottle has a serious drooping effect. 2 The longitudinal cross-sectional diameter of the blow molded product is too different.
2. The lateral wall thickness of the blow molded products is uneven:
Causes: 1 Pet Bottle Preform extrusion skew 2 mold sleeve and the core inside and outside the temperature difference is large 3 product shape asymmetry 4 pet bottle preform inflation ratio is too large
3. The orange peel pattern or pitting on the surface of the blow molded product:
Causes: 1 The mold is poorly ventilated. 2 The mold leaks or the mold cavity is condensed. 3. The pet bottle preform is poorly plasticized, and the pet bottle preform has melt fracture. 4 The inflation pressure is insufficient.
5 inflation speed is slow 6 inflation ratio is too small
4, the volume of blow molding products is reduced:
Causes: 1 The wall thickness of the pet bottle preform increases, which leads to the thickening of the product wall. 2 The shrinkage rate of the product increases, resulting in a shrinkage of the product size. The inflation pressure is small, and the product is not inflated to the cavity design size.
5, blow molding products product outline or graphic is not clear:
Causes: 1 cavity exhaust failure 2 inflation pressure is low 3 pet bottle preform melt temperature is low, material plasticization is poor 4 mold cooling temperature is low, the mold has 'condensation' phenomenon
6. Blow molding products black spots or black lines:
Cause: 1 The residence time in the barrel is too long. 2 The molten material is retained in the blown barrel or in the nozzle flow path. There are foreign objects in the 3 blown barrel. 4 The electric heating ring is loose or weak or electrically unstable, which causes the material to be degraded. 5 imperfect nozzle blocked the nozzle. 6 improper blow molding conditions. The blown barrel has cracks or screw depressions. The beer machine parts are short of oil. 7 raw materials are contaminated

Jilian Mold 5-gallon Pet Preform Is Durable

The most common shapes for Pet Bottle Preform are round, square, oval, and the like. From the point of view of use, they each have their own advantages and disadvantages. Round PET bottles have a high stiffness but are not aesthetically pleasing. The square PET bottle has a beautiful appearance, but it is not easy to control the uniform thickness of the PET bottle during molding. Elliptical PET bottles have higher stiffness, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the PET bottle, in addition to selecting the material with high rigidity, the shape of the PET bottle is also designed to enhance the rigidity and load resistance of the PET bottle.

Changing the surface shape of the PET bottle, such as the relatively thin middle portion of the PET bottle, increases the circumferential groove or rib of the surface of the PET bottle, which 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. When designing extruded PET bottles, if the material is high-density polyethylene or polypropylene, the PET bottle should have a rectangular or elliptical cross section. For low-density polyethylene or other flexible PET bottles, the cross section is round. Shaped as good.

This facilitates the extrusion of the contents from the PET bottle. In order to make the PET bottle wall thickness uniform, it should be noted that the shape of the PET bottle should be symmetrical. Minimize extreme stretching points and parts. Arc transitions are used at all transitions. The printed surface of the PET bottle is the most concentrated part of the consumer's attention. The printing surface should be flat and continuous; if the PET bottle contains handles, grooves, ribs and other structures, care should be taken not to cause inconvenience to the printing operation. When the surface of the PET bottle is marked, the surface of the label should be flat.

A "sash" can be designed on the surface of the PET bottle to make the label accurately positioned without moving. At the time of blow molding, the portion where the parison inflates first contacts always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions where the parison inflates the last contact, and the wall thickness of the portion is small.

Therefore, the edges and horns of the PET bottle should be designed to be rounded. Since most PETs have notch sensitivity, PET bottles are prone to cracks and cracks at sharp corners, roots of the mouth threads, necks, etc., so these parts should be designed to be rounded.

  If you have questions or needs related to pet products, then don't miss the Jilian mold. We are experts in this field. We have been loved by consumers in the market with our durable 5-Gallon Pet Preform. And praise, I believe that our other series of products will not let you down.

Design Planning For Pet Bottle Preform

Under normal circumstances, the planning of Pet Bottle Preform is mainly conceived under the premise of easy use, even if there are special circumstances. Because children are naive in behavioral and cognitive attitudes, often in the absence of attention of the guardian, some chemical or pharmaceutical PET bottles are opened, and even the ingestion has irreparable consequences. Therefore, it is necessary to plan some operational obstacles when planning the PET bottle, which has a relatively positive effect. The obstructive container is designed to be designed for child safety, mainly by intelligence rather than strength, thus eliminating the dangerous performance of children. For example, the opening method of the PET bottle is the method of pressing down and rotating, and the cap is pressed together to rotate the cap to open the bottle cap. Otherwise, no matter how much the rotation may be used, the force may not be opened. This is very good to avoid accidents in children. For the obstructive PET bottle, it is now the most upscale and fashionable planning idea. It is abundantly explained that this is a humanized plan and expresses the best concern for people.

In the PET bottle packaging, the degree of humanization and convenience is an important indicator. However, we carefully observed the PET bottle packaging in the domestic shopping malls, and put the appearance of PET bottle raw materials and PET bottles to a more important level. Whether the PET bottles are easy to use or not is retreated to the next position. However, it is necessary to realize that the appearance of PET bottles gives people a first impression. It can bring visual impact to customers for the first time. However, the comfort and convenience of human consumption is continuously brought to customers. Experience, it can retain customers and bring repeat customers to the product.

Jilian Mold 5-gallon Pet Preform Hygiene

Pet Bottle Preform are widely used in life, but they may release a strong chemical odor during processing. What should we do with this situation?

Changing the additive, the polyol is much less odorous. The use of a cleaner resin or an odorless resin is also very effective. The addition of an adsorbent such as zeolite serves to remove the odor of the material. The addition of an antibacterial agent to PET not only reduces the odor emitted by it, but also delays the aging, discoloration and embrittlement of the surface of the product.

Of course, what method is used also needs to be selected according to the source of the odor. In addition, the temperature control should be properly mastered during the processing, as well as environmental sanitation to ensure that the quality of the produced product is qualified.

Cleaning Method For Pet Bottle Preform

Blowing Pet Bottle Preform will have stains after long-term use, so we need to clean it regularly to ensure the cleanliness of blown PET products and achieve better results. Which cleaning methods can be used? Good cleaning effect?

When cleaning blown PET products, you can use the cleaning method, that is, use electric heater to heat it to above the melting point of PET, then stop heating, remove the heater, remove the starter, first use copper or copper shovel Go to the majority of the melt and then use brass wool for the final cleaning. Solvent cleaning can also be used, ie by means of acidic or alkaline chemicals, organic or celestial solvents, but recycling equipment should be provided to avoid environmental pollution. Among them, the equipment of the acidic or alkaline chemical cleaning method has low cost, but the cost of the chemical agent is high, and the cleaning efficiency is low, and the metal is generally corroded; the cleaning efficiency of the organic solvent is high.

In addition, the blown PET product can also be ultrasonically cleaned. This cleaning method has a good cleaning effect, but the cost of equipment and chemicals is high and corrosion problems are best used for post-cleaning to remove inorganic residues. Of course, there are also cleaning methods such as salt baths, ovens or fluidized beds.
