What factors affect the effect of blow molding processing

In the plastics industry, many companies, in order to save costs, often consider using blow molding as a manufacturing process for hollow products. Compared to injection molding, this method significantly reduces costs, which is why blow molding has experienced rapid development. However, in practice, the effectiveness of blow molding is often influenced by various factors. Next, the editor from Kunshan Juxinchang Company will summarize these factors for you.

The range of products processed by blow molding is very extensive, such as in the toy industry, packaging industry, electrical appliance industry, and other industries. Factors involved in the blow molding process, such as the position of the mold split (parting line), product slope, product layout, blow ratio, fillets, and appearance decoration, are considerations for mold engineers and blow molding engineers.

1、The position of the parting line: Before mold opening, the mold engineer needs to carefully consider how to part the mold, as this will affect the subsequent demolding of the product and its appearance.

2、The slope of the product: All surfaces parallel to the direction of mold movement should have a certain slope, which should be suitable for easy mold opening and convenient product removal. 

3、Check all functionalities: When used as a product, the fewer components and assembly work, the better, as it can reduce product costs. 

4、Blow molding ratio: During blow molding, pay attention to areas with very thin geometric shapes that may cause bulges or indentations. When the ratio of width to depth is too large, vacuum forming can be used as an auxiliary method. 

5、Radius principle: Avoid sharp edges, corners, sudden changes in surface, and sudden transitions in product diameter or wall thickness. 

6、The position of other inserts, vent slots, air intake needles, ejector pins, lettering, and labels should be carefully considered.

In summary, whether it's a small or large blow molding product, the effort and time required before development cannot be reduced. The editor from Kunshan Juxinchang Company reminds everyone to carefully consider the factors that may affect the blow molding processing effect, so as to ensure that every blow molding product matches both appearance and function well.
