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: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?
Bottle embryos should be kept in a constant temperature and humidity environment, preferably within a month. Otherwise, it will produce bottle embryo deformation and oxidation.Resulting in tensile, blow molding, there will be a risk of cracking.
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:50G how much is the bottle mold?
50G bottle embryo prices need to see what kind of manufacturer, the price is different.
Q:Blowing mould - the production process of beverage bottle
Bottle: cooling to room temperature after heating thermostat bottle, and then into the blowing mode, after stretching blowing make plastic tube embryo uniform distribution, and close to blowing mold, after high pressure blowing into complete cooling air, cool completely when blowing gas opened, forming complete beverage bottle.
Q:How much molten PET temperature is molding in injection molding? Hot runner mold?
Melting is the process of heating a substance from a solid to a liquid. It is a more common type of change in the state of matter.
Q:What are the parameters needed to buy a bottle blowing machine?
When the nozzle is filled with the mold, the temperature of the melt will be reduced because of the close to the mold of the bottle at low temperature, thus affecting the transparency of the bottom of the embryo. To avoid this, set a heating ring around the nozzle, or try to take proper thermal insulation between the nozzle and the mold. In addition, the diameter of the runner and gate is appropriately increased, and the transparency of the bottom of the embryo is also increased.
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 are plastic bottles made?
First of all, to design, determine and manufacture molds, glass raw materials to quartz sand as the main raw material, and other accessories at high temperature dissolved into liquid, and then injected into the mold, cooling, incision and tempering, forming glass bottles. Glass bottles generally have rigid signs, signs are also made of mold shapes.
Q:When the bottle blower blows, the bottom of the bottle can not be formed.
The bottle bottom is white, the temperature of the bottle embryo is low, the pre blowing flow is large and the pre blowing time is long
