Pet Preform Surface

Posted by nicolepreform on Mär 25, 2019 in News

The choice of Pet Preform parting surface is the first step in mold design. It is affected by many factors such as shape, appearance, wall thickness, dimensional accuracy and number of cavities. The parting surface of the general product is easy to determine. But for some parts with side cores, or when it comes to pillows, bumps and inserts, this is not easy.

Usually, the parting surface will follow the following principles:

1. For easy demolding

The parting surface, that is, the product can smoothly come out from the surface of the mold. Therefore, the position of the parting surface should be selected among the parts with the largest product section size. This is the most basic principle.

2. position

When determining the position of the product in the mold, the location of the parting surface should be such as to prevent the product from forming side holes or side buckles and avoid complicated mold structures.

3. shape

Typically, the parting surface is perpendicular to the direction in which the injection mold opens. The parting surface is only in other shapes in special cases. The shape of the parting surface is based on the principle of easy processing and demolding. For example, some curved products are classified according to the curvature of the bend.

4. Ensure product appearance and quality

Do not place the parting surface on the smooth outer surface of the product. In general, the appearance of the surface does not allow lines and other lines that affect aesthetics; some products have concentricity requirements, and all parts with the same concentricity must be placed on the same side to ensure their concentricity.

5. Consider lateral mold opening distance

Typically, the distance from the transverse mechanical mold opening is relatively small. Therefore, when the parting surface is selected, the direction in which the core distance is long should be selected in the direction in which the front and rear molds are opened and closed, and the short direction is used as the side type.

6. Consider clamping force

The lateral clamping force of the mold is relatively small. Therefore, for a large product having a large projected area, the direction of the large projected area should be placed in the direction in which the front and rear molds are opened and closed, and the side projected area should be smaller.

7. Good for ventilation

When the parting surface is used as the main exhaust, the parting surface should be designed at the end of the plastic flow to facilitate venting.

8. Mold parts are easy to process

When selecting a parting surface, the mold should be divided into easy-to-machine parts to reduce the processing difficulty.

9. r parting surface

For many products, there is a full circle of R angles on the parting surface. At this point, the classification is based on the best R classification and there is no sharp side.

Jilian Mold Production Of Completely Assured China Pet Bottle

Posted by nicolepreform on Mär 13, 2019 in News

(1) When designing extruded Pet Preform, if the material is made of high-density polyethylene or polypropylene, the cross-section of the pet bottle should be rectangular or elliptical, for low-density polyethylene or other flexible pet bottles. The 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. The design of the pet bottle opening 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 mechanical properties of the pet bottle. Therefore, the bottom of the pet bottle is generally designed to be concave; the corners of the pet bottle and the inner recesses are all excessively curved. In order to facilitate the stacking of pet bottles, increase the stacking stability of pet bottles, and the inner bottom of pet bottles should be designed with inner grooves.
(2) When the surface of the pet bottle is marked with a label, 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. Change the surface shape of the pet bottle, such as the middle of the pet bottle 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 pet bottles under long-term load.
(3) 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 inconvenience the printing operation. The oval pet bottle has a higher rigidity, 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 should be designed to enhance the rigidity and load resistance of the pet bottle.
(4) Since most pets have notch sensitivity, pet bottles are prone to cracks and cracks at sharp corners, roots of the mouth thread, neck, etc., so these parts should be designed to be rounded. For the transfer point of the rectangular pet bottle, it is necessary to support most of the load of the pet bottle, so locally increasing the wall thickness at this place is also advantageous for improving the rigidity and load resistance of the pet bottle.

Application And Recycling Of Pet Preform

Posted by nicolepreform on Mär 8, 2019 in News

Pet bottles are not only widely used in the packaging of carbonated beverages, water, juices and tea beverages, but are also the largest use of beverage packaging today, and are widely used in many fields of food, chemical, pharmaceutical and packaging.

Pet has a wide range of applications in the packaging industry, whether it is packaging film, sheet or beer bottles, use pet. But when these materials are discarded, they face the problem of how to deal with tens of billions of China Pet Bottle every year. It is expected that in the next five years, 50 million tons of PET will be used to make pet bottles every year. Therefore, pet bottle recycling can not only solve environmental problems, but also serve as a new raw material resource to alleviate the contradiction of shortage of PET raw materials in China.

Yes, in reviewing China’s 30 years of reform and opening up, China has made remarkable achievements in the economic field, but it has also caused very serious damage to the Chinese environment. Water pollution, air pollution, solid waste pollution, etc. The Chinese economy has shrunk. People have gradually realized this problem, and accordingly put forward a series of measures such as the strategy of sustainable development of green GDP and the circular economy strategy. Therefore, recycling pet bottles meets the real problems faced by China and has great benefits for environmental protection, resource conservation and sustainable development.

The physical recycling method of the pet bottle is relatively simple, mainly to dry and granulate the Pet Preform waste. The physical handling of pet bottles is closely related to the sorting process.

There are two main methods of physical recovery:
First, the discarded pet bottle is chopped, and HDPE, aluminum, paper and binder are separated from the PET and PET chips, and then washed, dried, and granulated;

Satisfied China Pet Bottle

Posted by nicolepreform on Mär 1, 2019 in News

The rheology of PET in molten state is better, and the effect of pressure on viscosity is greater than temperature. Therefore, the fluidity of the melt is mainly changed from pressure.

1. Processing of plastics Because PET macromolecules contain a lipid group and have certain hydrophilicity, the pellets are sensitive to water at high temperatures. When the moisture content exceeds the limit, the molecular weight of PET decreases during processing, and the product is colored. Become brittle. Therefore, the material must be dried before processing, and its drying temperature is 150 ° C, 4 hours or more, generally 170 ° C, 3-4 hours. Airborne methods can be used to verify that the material is completely dry. The proportion of recycled materials should not exceed 25%, and the recycled materials should be thoroughly dried.


2. The selection of PET for injection molding machine is short due to the short time after melting point, and the melting point is higher. Therefore, it is necessary to select an injection system with more temperature control sections and less self-friction heat during plasticization, and the actual product (aqueous slag) The weight should not be less than 2/3 of the machine’s injection volume. Based on these requirements, Ramada has developed a small and medium series of PET plasticizing systems in recent years. The clamping force is selected to be greater than 6300t/m2.


3, mold and gate design Pet Preform are generally formed by hot runner mold, between the mold and the injection molding machine template should have a heat insulation board, the thickness of about 12mm, and the insulation board must withstand high pressure. Exhaust gas must be sufficient to avoid local overheating or chipping, but the depth of the exhaust port should not exceed 0.03mm, otherwise it will easily produce flash.


4, the melting temperature can be measured by the air-launch method. Between 270 and 295 ° C, the enhanced grade GF-PET can be set to 290-315 ° C and the like.


5, the injection speed is generally faster, to prevent premature coagulation during injection. But too fast, the high shear rate makes the material brittle. The shot is usually completed in 4 seconds.


6, the lower the back pressure, the better, so as not to wear. Generally no more than 100bar. Usually no need to use.


7. Do not use excessive residence time for the residence time to prevent molecular weight from falling. Try to avoid temperatures above 300 °C. If the shutdown is less than 15 minutes. Only need to be air-blasted; if it is more than 15 minutes, clean it with viscosity PE and reduce the temperature of the barrel to PE temperature until it is turned on again.
