What aspects affect the effectiveness of plastic blow molding processing

In the plastic industry, many companies consider using blow molding technology to produce hollow products in order to save costs. Compared to injection molding, this greatly reduces costs. Therefore, the method of plastic blow molding has also developed rapidly. Blow molded products are also widely applicable, such as in the toy industry, packaging industry, electrical industry, and other industries.

The position of the mold separation (closing line), product slope, product layout, inflation ratio, rounded corners, and appearance modification involved in the plastic blow molding process are factors that mold engineers and blow molding engineers need to consider. The specific analysis of Juxinchang is as follows:

1. Position of the mold line. Before opening the mold, the mold engineer needs to carefully consider how to divide the mold, which will affect the subsequent production of the product and the appearance of the product;

2. Product slope. All surfaces parallel to the direction of mold movement should have a certain slope, and the slope should be such that the mold can be easily opened for easy removal of the product;

3. Check all usage functions. When used as a product, it is better to have fewer components and assembly work, as it can reduce the cost of the product;

4. Inflation ratio. During inflation, pay attention to areas with extremely thin geometric shapes, which may be protruding or recessed. When the width to depth ratio is too large, vacuum forming can be used as an auxiliary method;

5. Principle of radius. Avoid sharp edges, corners, sudden changes in surface, sudden changes in product diameter or wall thickness;

6. The positions of inserts, exhaust slots, intake needles, top pin holes, engraving, and labels need to be carefully considered.

In summary, whether it is a small blow molded product or a large blow molded product, the energy and time required before development cannot be reduced. It is necessary to carefully consider the factors that may affect the plastic blow molding processing effect in order to match the appearance and function of each blow molded product well.
