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: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?
There is no obvious difference between the two, meaning the same, that is not yet completely processed into semi-finished products.
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 northern weather is relatively dry, the injection bottle embryos need to wet about four days, and then pull out for eight hours, while the South can directly blow bottles.
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:Blowing mould - the production process of beverage bottle
The two step: divided into embryo injection and blowing bottles.Injection molding: plastic particles are heated, melted, injected into a mold of a bottle embryo, cooled and shaped into semi-finished products (similar to a test tube shaped bottle embryo, also known as Guan Pei).
Q:How much molten PET temperature is molding in injection molding? Hot runner mold?
Injection molding PET bottle embryo temperature at 270 degrees to 290 degrees melting is a hot runner mold.
Q:What is the process of blowing bottles in a bottle blowing machine?
Two the operation of automatic bottle blowing machine through the manipulator will be blowing together, eliminating the intermediate process of artificial bottle preheated in mold. Greatly speeding up the production rate, of course the price for higher than the semi-automatic.
Q:What about the white circle at the bottom of the injection bottle?
The phenomenon of silver white streak appeared on the surface of the resin molded flow direction. (Guangdong vallink modified plastics provided)When the 1: resin breaks down during overheating, the setting temperature of the heating cylinder is lowered.Insufficient drying of 2: resin.3: air mixing will also cause this phenomenon, then can improve the back pressure to try. The temperature of the heating cylinder under the hopper is too high and sometimes prevents air from being discharged.4: can cause too much injection speed. The reason is that the mold gate is too small and cut the high heat of the nozzle aperture is too small will exhibit the same phenomenon, so you have to reduce the injection speed, to prevent the burning, or the gate, or the nozzle diameter enlargement on the line.
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,
