We are specializing in the production of various specifications of PET edible oil bottle perform,mineral water bottle perform, PET wide mouth bottle perform, 3 gallons, 5 gallons of preform and various ancillary lid and handle.

The characteristics of the raw material:

The raw material is with low heavy metal content, acetaldehyde content is low, the color value, characteristic viscosity stability. 

Due to the adoption of the process recipe and unique production technology, the product has excellent processing properties, low processing temperature, processing a wide range of products, high transparency, high rate of finished products, which makes the bottle making process, high production efficiency, less degradation, acetaldehyde content is low, in order to ensure the health and safety at the same time, effectively ensure the pure water, mineral water, distilled water and taste unique to their respective.

 

The main production of various kinds of capacity of PET bottles, beverage bottles,mineral water bottles, PET wide mouth bottle and various small bucket drums etc.

Q:What should I pay attention to when molding PET bottles?
Because PET macromolecules contain lipid groups and have certain hydrophilicity, the pellets are sensitive to water at high temperature. When the moisture content exceeds the limit, the molecular weight of PET decreases during processing, and the products become brittle and brittle. In this case, the material must be dried before being processed. The drying temperature is 150 degrees centigrade and more than 4 hours. The temperature is usually 170 DEG C and 3-4 hours. The air can be used to check whether the material is completely dry.
Q:PET how about the bubbles in the bottle embryo?
Depends on where the bubble is, what kind of bubble appears, it is best to have a good map to judge. Now give some suggestions: 1. increase the back pressure; 2, separate the big 2 note temperature; 3. check the cooling water is normal; 4. check the 2 screw vent.
Q:What is the difference between bottle blank and bottle embryo? What should be called "bottle blank" or "bottle embryo" before the bottle blowing?
As for which one to see their respective habits. Literally, the billet should be a semi-finished product, and the embryo should be something that has life.
Q:PET how long can the bottle embryo be filled with PET hot filling bottle after long time? What are the conditions for preservation of the bottle embryo?
The most important thing is that after blowing the finished products, especially the gas bottle, such as cola, will increase the leak rate, while dropping the experiment, more likely to drop the risk of leakage.
Q:What happened to the bottle embryo in the injection molding machine?
(1) the actual clamping force of the machine is insufficient. When choosing an injection molding machine, the rated clamping force of the machine must be higher than the tension formed by the longitudinal projection area of the injection molding product, otherwise it will cause bulging and flying edges.(2) the clamping device for regulating the poor, not straight or toggle mechanism, or the upper and lower mold is not balanced, mould parallelism cannot reach a phenomenon caused by unilateral side mold is screwed tightly while the other side does not close the case, when the injection will appear flash.(3) the mold itself is of poor parallelism, or it is not parallel, or the template is not parallel, or the tie rod is uneven distribution of force and uneven deformation, these will cause the mold is not close, resulting in flying edge.(4) stopping ring wear; nozzle spring spring failure; barrel screw or excessive wear; inlet cooling system caused by the failure of "bridge" phenomenon; the feeding amount of the barrel setting lack of buffer is too small and so may cause flash appears repeatedly, must be timely repair or replacement of parts.
Q:When using negative pressure to measure the tightness of bottle cap, use bottle embryo or bottle
The clamping head method uses the bottle mouth, whether it is a bottle embryo or a bottle, and cuts the bottle mouth test.
Q:How much molten PET temperature is molding in injection molding? Hot runner mold?
Melting requires absorption of heat and is endothermic. Crystals have a melting point called melting point. Amorphous crystals have no definite melting temperature. The inverse process of melting is solidification.
Q:How are plastic bottles made?
The bottle embryo is irradiated by a high temperature lamp tube to heat and soften the part of the bottle embryo. In order to keep the bottle mouth shape, the bottle embryo mouth needs no heating, so a cooling device is needed to carry out the cooling operation.
Q:How do I make the thread of this plastic bottle? Must I have a bottle of embryo in it?
What can be done is that one step blowing, with hollow blow molding machine, usually with PE raw material to blow, there are many such blowing bottles.
Q:When the bottle blower blows, the bottom of the bottle can not be formed.
1 out of six is inherently unstable, the more he will not be a problem, or blow molding machine, injection molding machine, temperature control, cooling water machine adjust slowly, 2 Taiwan 60 kg air compressor, 1 sets of 1.2 air compressor, the pressure is high, the temperature increase reduce speed,
