One-step and two-step PET cosmetics packaging production of cosmetics packaging production machine

Factors influencing the PET cosmetics packaging production wall thickness control is more, mainly involves the cosmetics packaging production wall thickness distribution of the embryo, cosmetics packaging production equipment performance, cosmetics packaging production factors such as the quality of the mould, notably the embryo of wall thickness distribution is most important. And the wall thickness distribution and the quality of the PET raw materials, the injection equipment performance, cosmetics packaging production is related to the quality of embryos die. Especially the embryo 'one-step' cosmetics packaging production mold directly affects the quality of the wall thickness distribution of the PET cosmetics packaging production. First of all, the PET raw materials must meet the requirements of injection grade cosmetics packaging production, otherwise it is a good equipment is not likely to produce uniform wall thickness distribution of embryo. Second, to the injection pressure, injection molding, mold core rigidity, mold temperature, mold assembly accuracy, precision injection template parallelism between these elements are well controlled. In the cosmetics packaging production of high quality billet, billet heating quality of cosmetics packaging production becomes the guarantee cosmetics packaging production wall thickness uniformity of the key. 'Two steps' than 'one-step' four station equipment temperature control to cosmetics packaging production embryo is relatively easier. This is because of the 'two steps' cosmetics packaging production embryos in the process of heating, combining the rotation and revolution movement, and the heating time is longer, so easy to make cosmetics packaging production temperature uniformity in embryo. 'One-step' four station cosmetics packaging production of embryos in the process of heating without rotation, so the wall thickness distribution of cosmetics packaging production embryo has a higher request, the performance of the heating system and the control requirements more stringent. In actual production, the processors are often in the process of the final system caused by improper process set PET cosmetics packaging production wall thickness distribution. The following are the most common three kind of unhealthy phenomenon appeared: low upper thick thin at the bottom of the cosmetics packaging production. This is by drawing speed is too fast, a plastic, improper control of pressure is too low, second time, when the tensile plastic upper and lower parts of improper temperature control. At the bottom of the thin upper thick low cosmetics packaging production. The reason is that the tensile speed too slow, a plastic pressure is too high, second time is not suitable, tensile plastic cosmetics packaging production embryo when the upper temperature is low, the lower temperature is high. Low overall cosmetics packaging production of cosmetics packaging production wall is too thin. The main reason is the cosmetics packaging production stretching temperature is too high and cosmetics packaging production embryo-cells stretching ratio is too big. Because cosmetics packaging production embryo quality determines the qualification rate of products, so must be tested for cosmetics packaging production embryo. Germany Krones company developed an online cosmetics packaging production inspection equipment of the embryo that can detect the concentricity of embryo, cosmetics packaging production quality indexes such as diameter and wall thickness distribution, an hour can detect 72000 cosmetics packaging production base. The device can be installed after the automatic stacking machine, also can be installed in the Krones company Contiform transverse feeding wheel hollow plastic molding machines. PET cosmetics packaging production efficiency is the cosmetics packaging production equipment is very important technical indicators, what do you think the system efficiency of cosmetics packaging production machine what are the factors? Affects the system efficiency of cosmetics packaging production machine has the following several factors: low cosmetics packaging production quality of embryo, including the design of cosmetics packaging production embryo, dimensional accuracy, wall thickness uniformity; Low cosmetics packaging machine production of cosmetics packaging production embryo heating system; Second-ranking cosmetics packaging production machine cosmetics embryo stretching and plastic packaging production system; The mould and the low cosmetics packaging production system. Influence the efficiency of the PET cosmetics packaging production system is a major factor in the electromagnetic valve, cosmetics packaging production precision of mechanical and electrical magnetic valve, reaction time and life is very important to improve the single lumen output. My company USES NORGREN company designed for our custom solenoid valve, due to the piston parts of the valve for all hard seal, the reaction time accuracy up to one over one thousand of a second, life up to 50 million times, and thus ensure the tech-long cosmetics packaging production equipment of high efficiency. In addition, the other main factors influencing the system efficiency is the overall level of machining and assembly precision. Only high precision parts and strict assembly was able to create a stable high-speed cosmetics packaging production machine. 'Two steps' equipment production efficiency is the key: optimization of cosmetics packaging production embryo heating system, reduce the heating time. Low improve cosmetics packaging production operation of embryo transfer transmission speed; * improve the performance of cosmetics packaging production embryo fast and stable positioning; Low to shorten mold opening and closing and clamping head lift time; The increase in low cavity number.
