Which manufacturer is low in medical plastic? MGG has a sound service system, the supplied solid medicinal plastic bottle, PET pharmaceutical plastic bottle, pharmaceutical plastic bottle, medical plastic bottle cost, welcome to inquire. Because most plastics have unevenness, plastic bottles It is pointed out that the roots, necks and other threads, easy to crack and cracks, so these should be placed into rounded angles. When selecting a label plastic bottle appearance, it should be noted that the surface of the plastic bottle is smooth and the yi of the blow molded blank, always tends to hardeize the yi portion. So the part of the wall thickness.
The edges and corners areas, the parison blows the zui end contact portion, and the partial wall thickness is small. Therefore, the marginal and erase portions of the plastic bottle should be planned to be rounded. A plastic bottle whose shape varies, for example, a plastic bottle relatively thin, an annular groove or rib of a plastic appearance in the middle, and can further enhance plastic rigidity and resistance.
Longitudinal trenches or reinforcement can eliminate plastic bottles for a long period of time offset load, resulting in sagging or deformation. Plastic bottle processing project with blow molding machine is very common in the process, so it is necessary to pay attention to this process. What I want to tell you is that temperature changes are critical to the treatment of plastic bottles.
In the operation processing of the hollow blow molding machine, it is necessary to pay attention to temperature control to ensure that some of their production is suitable for plastic bottles. Inactivity: Zui high temperature does not occur at a certain pressure. It is a certain number of plastic capillary rheologic in the top of the cylinder head, when heated to a certain temperature, 50 mPa after 10 minutes after heating, constant pressure, if the material is not problematic, the material is re-adds the temperature of 10 degrees After 10 minutes of insulation, the constant voltage is applied, so continues to be suspended from the mouthmail, and the material temperature of the melt flow is inactive temperature of 10 degrees.
Activity temperature TF: means a highly elastic state of the amorphous polymer to a viscous stream state.
