At the beginning, the arguer was more than that in the garden, and there would be a "house" income every year. Production sale: new electronic components; sectors, high-frequency winding coil inductive components, sensors, and high-density digital optical discs with junction development, etc. (Ie the guarantee of the product to obtain a Z high function orientation temperature). In the manifold, the molten resin is retained, PE Plastic bottle and the differentiation, deterioration, deterioration, etc. The axial stretch reaches 2.2.The generation of wall thickness is completely yard in all parts of the bottle embryo and reaches NSR. The axial stretching of the elliptical or rectangular bottle cannot be too large, because if the axial stretch is too large, the bottle embryo is subjected to a larger stroke, which causes the bottom molding or the wall thickness. The stretch to 11 or more is hard to achieve, the Z large tensile ratio of PET is 12. It is relatively easy to adjust the temperature of the bottle embryo with an aluminum rod similar to the core, although the temperature of the inner wall is lower than the external, but the wall thickness will be compensated.One-step method is difficult to control in the internal temperature of the bottle embryo in some machines, although the average temperature of the step method is higher than the second step, but the colder bottle embryo means the prolongation of the cycle and the poor molding,The bottle embryo in one step is thicker.8 are not allowed, and the CSD bottle tension is usually 10 or more. The advantage of the radial stretching is 3.5 to 3. (The content of the article is from the network.
