The requirements of food, medicine, daily necessities, cosmetics, and so on packaging bottles are becoming more and more strict with the demand, and the use of traditional extrusion and blowing can not meet the requirements of plastic packaging bottles. At this time, the use of one-step injection and draw-blowing machine is inevitable. What are the advantages and disadvantages of one-step injection and draw-blowing machines?
The processing technology of injection and blow forming is the product injection molding of the embryo tube, and then the stretch injection molding, and then the mold. The products produced by this type of processing process have no flash edges, no waste plastic, very few shortcomings, and also have a mouth, bottom end, slit line, and more compatibility and higher stiffness.
Advantages:
1. One-step injection molding machine, from type embryo injection to stretch injection molding, only each machine and equipment is completed, thus saving a lot of labor, energy consumption and land.
2. The products produced by the one-step injection molding machine can be thinner than those produced by the non-Rashen injection molding production, and the products are not easy to return to moisture, not easy to environmental pollution, forming diversification, and the unqualified rate is low.

3. The one-step automatic blowing function is very good for the bottle mouth of high-precision, external thread parts of the goods, very for the formation of some flat utensils is also very good control.
4. Save cost, because the one-step automatic blowing machine system does not repeatedly warm the bottle embryo can maintain a high speed of forming, the basic principle is to use the heat guaranteed when the bottle embryo molding to carry out the whole process of lashes injection molding, so the goal is to promote the heating energy cost of reheating needs to be zero, much much to reduce the water cooling time of the bottle embryo. The practical equipment of the cooling water machine is maintained.
5. Remove adverse molding conditions and reduce the molding process: The one-step method is the scientific research achievement of improving the molding precision and optimizing the structure of the process flow. The technology throws off a part of the complicated process flow and consists of an improved process flow, which is a technology that immediately maintains the smooth production of goods, improves the yield, and saves energy.
6. Greatly reduces the cost of transportation. The transportation costs of PET bottles, bottle embryos, and PET raw materials were comprehensively investigated.
