(1) Plastic bottles are superior to plastic bottles when used with pressure-sensitive plastic bottles, high-density plastic bottles or other plastic bottles, horizontal surfaces similar to plastic bottles, rectangular or polyethylene bottles, low-density plastic bottles, or other flexible plastic bottles. The design of the plastic bottle mouth should be combined with the Sowa sealing machine first, which is a good place for plastic bottle mouth experts. In terms of the mechanical properties of plastic bottles, the bottom of the plastic bottle is the weakest part. In this case, the plastic bottle-shaped bottom is usually concave in design. Plastic bottle corner processing, concave processing, average large arc is redundant. For the sake of convenience, the plastic bottle is discharged, and the design of the plastic bottle sedimentation, the bottom of the plastic bottle and the concave tank is added.
(2) When using the surface of a plastic bottle, the surface should be flat. 1. Plastic bottle surface design "frame", standard positioning, non-productive transfer. In blow molding, part of the blow mold, the part where the tip of the neck contacts and the part where the inflated part is pre-hardened. The corner portion of the flatulence and the contact portion wall of the flatulence-type flatulence are relatively small. The reason is that the surface shape of the plastic bottle, the central phase of the plastic bottle, and a small amount of details modified by the rounded corners of the side bowls of the plastic bottle increase the circumferential concave or convex ridge of the plastic bottle surface, which may have higher rigidity and total resistance of the plastic bottle. curvature. A sagging can or a strengthened, erasable plastic bottle that has been chronically unloaded, shifted, sagged or deformed.
(3) The plastic bottle-shaped printing surface is the part that consumers focus on. The printing surface is flat and connected ; plastic bottles, concave cans, reinforced materials, etc. Installed on the handle, it is not convenient to print. Oval plastic bottles have higher rigidity and pressure, but the manufacturing cost of imitation is higher. Reasons: the rigidity of plastic bottles, the selection of high-quality materials, the appearance design of plastic bottles that need to be reduced in size, the rigidity of plastic bottles, and the overall load resistance.
(4) Most of the plastic tools have sensitive notches, sharp corner processing of plastic bottles, mouth-shaped screw roots, necks and other parts that are prone to cracks, and the reasons for this important part. On the contrary, the conversion and exchange of the shape of the rectangular plastic bottle supports most of the load required by the shape of the plastic bottle, resulting in a local increase in the processing wall thickness, which reduces the advantage of the load strength of the shape of the plastic bottle.
