6 factors affecting the processing effect of plastic blow molding

In the plastic industry, many companies consider using blow molding technology to produce hollow products in order to save costs. This significantly reduces costs compared to injection molding,

Therefore, the methods of blow molding processing have also developed rapidly. Blow molded products are also suitable for a wide range of industries, such as the toy industry, packaging industry, electrical industry, and other industries.

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

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

2、 Check all usage functions. When used as a product, the fewer components and assembly work, the better, which can reduce the cost of the product.

3、 Inflation ratio. Pay attention to areas that trigger 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 aid.

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

5、 The slope of the product. All surfaces parallel to the direction of mold movement should have some slope, which should make it easy to open the mold and facilitate the removal of the product.

6、 The position of the mold line. Before opening the mold, the mold engineer needs to carefully consider how to divide the mold, as this will affect the subsequent production and appearance of the product.

Based on the above points, whether it is a small blow molded product or a large blow molded product, the energy and time required for development cannot be reduced. Factors that may affect the blow molding processing effect must be carefully considered in order to match the appearance and function of each blow molded product.
