Pet Bottle Preform Blank Corner Wall Thickness Is Small

When the surface of the PET bottle is marked, the surface of the label should be flat. A “sash” can be designed on the surface of the PET bottle to make the label accurately positioned without moving. At the time of blow molding, the part of the Pet Bottle Preform that inflates the first contact always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions of the pet bottle preform that are inflated and contacted, and the wall thickness of the portion is small. Therefore, the edges and horns of the PET bottle should be designed to be rounded. Changing the surface shape of the PET bottle, such as the relatively thin middle portion of the PET bottle, increases the circumferential groove or rib of the surface of the PET bottle, which can improve the rigidity and bending resistance of the PET bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the PET bottle under long-term load. The printed surface of the PET bottle is the part of the consumer's attention. The printing surface should be flat and continuous; if the PET bottle contains handles, grooves, ribs and other structures, care should be taken not to cause inconvenience to the printing operation. Elliptical PET bottles have higher stiffness, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the PET bottle, in addition to selecting the material with high rigidity, the shape of the PET bottle is also designed to enhance the rigidity and load resistance of the PET bottle. Since most plastics have notch sensitivity, PET bottles are prone to cracks and cracks at sharp corners, roots of the mouth threads, necks, etc., so these parts should be designed to be rounded. For the transfer of a rectangular PET bottle, it is necessary to support most of the load of the PET bottle, so locally increasing the wall thickness at that place is also advantageous for improving the rigidity and load resistance of the PET bottle. Jilian Plastic Mould is a manufacturer of high quality pet products. We have a good reputation and influence in the market. Our 5-Gallon Pet Preform have won the favor of many customers. I believe that we will not choose us. Let you down.
