The use of PET bottle flakes to strapping and tear-resistant monofilament production is of great influence, the purpose is to keep raw material costs as low as possible, especially since the recycled material can be used without any problem, as long as the production line is correspondingly design. So far, the intrinsic viscosity of about 0.9 to 1.3 of PET virgin material to be mixed. Mixing ratio and packaged with the required strength and quality of scrap and humidity are associated. Moreover, production line design plays an important role. PET bottle scrap the application possibilities are subject to consistency and filter fineness of the filtration system of ad hoc decisions. It is also possible to increase the intrinsic viscosity of 1.0 and higher scrap, which can be 100% recycled material.

In conclusion

When processing PET bottle flakes, melt filter is very important. Many of the materials or the production process-related issues can only be resolved through proper melt filtration. Gneuss (Gneuss) rotary filter system RSFgenius company has some perfect features. It fully automated operation, the process is stable, and efficient. Therefore, it is fully in line with the direct recovery of scrap PET bottle requirements, which through its worldwide popularity in the proven.

pet bottle production process and presentation!

If the data is poor, PET bottle blow molding process of adjustment for the corresponding data conducted. Very stringent requirements on the process, even difficult blow qualified bottle. PET plastic bottle blow molding processing technology and equipment, PET stress analyzer introduction. One is pressurized bottle, PET bottle blow molding can be divided into two categories.

PET plastic bottle blow molding processing technology and equipment, PET stress analyzer introduction.

One is pressurized bottle, PET bottle blow molding can be divided into two categories. Such as filling carbonated beverage bottles; the other for non-pressure bottle, such as filling water, tea, oil bottle. Tea beverage bottles is blended with polyethylene terephthalate and polyethylene naphthalate (PEN modified PET or PET bottle with a thermoplastic polyarylate composite bottle, is the classification of thermal bottle, can heat above 80 ℃; it is a cold bottle of water bottles, The molding process hot and cold bottle bottle no resemblance to the heat resistance requirements discussed here mainly cold bottle of pressurized bottles molding process.

At the rear near the mandrel with 0.10 mm deep open side of the groove, so that the ends of the parison wedging groove, avoid blow station go to the parison forming station from the process, the parison its elastic shrinking lead to neck screw dislocation. Seal grooves play a role in reducing leakage during blow compressed air. 6, choose the value of length to diameter mandrel

Length and diameter of the mandrel is mainly determined by the parison, the mandrel diameter than the inner diameter of the bottle neck smaller, easy to release the bottle. But mandrel diameter should take large values ??as much as possible within the scope of the bottleneck inner diameter in order to avoid excessive blow-up ratio. Coaxial mandrel diameter should be within 0.05 to 0.08 mm. Bottle parts mandrel diameter is the outer diameter of the bottle and the bottle on the thickness, the range is usually dark green bottle bottle rod diameter equal to the outer diameter minus twice the wall thickness of the bottle. 7, the distance between the bottom of the mandrel and the size of the bottom of the parison is determined

The distance between the bottom of the parison thickness dimension is, its size is reasonable or not the value directly affects the thickness of the bottom of the bottle meets the requirements. Generally calculated as: thickness (B) of the parison bottom of the bottle is equal to the minimum thickness (T) of plus 0.1 times the weight of the bottle. Mandrel body material of choice for the alloy tool steel, hardness HRC52-54, slightly lower than the hardness of the mold collar. Mandrel surface in contact with the melt to the melt flow direction along the polished and chrome plated for easy filling and melt parison mold. PET bottle blow molding and demolding station, gas continues circulating in the mandrel, the mandrel to ensure a more uniform temperature distribution. Mandrel temperature value of each segment: the head (corresponding parison neck) take 45 ℃ ~ 55 ℃, middle (corresponding type body) take 40 ℃ ~ 50 ℃, the tail take 23 ℃ ~ 35 ℃. The parison injection station, due to high melt temperature, the mandrel is in the upper limit of the temperature range, the temperature of the mandrel go demolding station when lowered due to the cold and the lower limit. In the top of the stripping station after the bottle from the outside of the mandrel head air cooling to reduce the temperature of the mandrel.
