Pet plastic bottle design to consider the problem

Author: mgg-Plastic bottle manufacturer

Injection molding products manufacturers need to consider the design of plastic bottles. (1) When designing a press-type plastic bottle, in the case of high-density polyethylene and polypropylene, the section of the plastic bottle is low-density polyethylene and other flexible plastic bottles in a rectangular or elliptical shape, material is low-density polyethylene and other flexible plastic bottles. It is best to do it into a circle. Such content is extruded from the plastic bottle.

Plastic bottles and plastic parts are mainly bottle caps and seals. The design of the plastic bottle should be subjected to a key test, how can the plastic bottle port in the plastic bottle of the plastic bottle, is a weak part of the performance of plastic bottle mechanics. Therefore, the bottom of the plastic bottle is typically designed in the inner concave shape.

The position of the plastic bottle angle, and the inner depression is too large. Because the stack of plastic bottles is very convenient, the stability of the ceiling of the plastic bottle has increased, and there is internal groove at the bottom of the plastic bottle. (2) In the case of the surface of the plastic bottle, the reference sticker is flat.

The surface design "box" in the plastic bottle is not moved in an incorrect position. When molding is formed, the portion that first contact is easily hardened. Therefore, the wall of that part will become thick.

The edges and rotation portions are type expansion, the end contact, and the walls thereof will become thick. Therefore, the edge and corner portion of the plastic bottle are designed to be rounded. If the surface shape of the plastic bottle is changed, the portion of the plastic bottle is relatively thinner, and the grooves and ribs around the surface of the plastic bottle can be increased, and the stiffness and detergent of the plastic bottle can be improved.

By strengthening longitudinal grooves or ribs, long-term load, sagging or deformation of the plastic bottle can be removed. (3) The printing surface of the plastic bottle is the site of consumer concentration. The print surface is flat, continuous; the plastic bottle can not be careful when designing the steering wheel, groove, ribs, etc.

Although the elliptical plastic bottle is strong, the manufacturing cost of the mold is also very high. Therefore, in order to ensure the stiffness of the plastic bottle, in addition to the material having a high stiffness, the stiffness and load resistance strength of the plastic bottle are improved by the shape of the plastic bottle. (4) Many plastics are valved, so the plastic bottle, the front end, the screw root of the front end, the mouth, the neck, etc., which is easy to produce cracks and cracks, so these parts are designed as a rounded angle.

For the intersection of the rectangular plastic bottle, in order to support most of the load of the plastic bottle, the portion of the wall will be thicker, and the stiffness and load resistance of the plastic bottle can be improved.
