Mold injection blow molding, what are the benefits of mold injection blow molding?

In view of the current situation, the development of the plastic mold industry indicates that the dispersion rate of industry-related common sense will become more and more light. The common sense point introduced below is the benefits of injection molding and blow molding:

Mold electroplating, what are the notices of mold electroplating?
Mold electroplating, what are the notices of mold electroplating? Due to the development of new technology and aluminum templates, especially for injection mold planning, aluminum molds are also more and more widely used in blow molding, R.I.M. molds, rubber molds, layout foam molds and R.T.M. Although it may not be suitable for all application platforms, in fact, its application has become more and more widespread. Everyone is expected to extend the production and service life of the mold, for example, to accept ancient workers …

  • 1. When the melt is injected into the cavity of the parison mold, it is subject to an inevitable orientation effect in the circumferential direction. In addition, the temperature of the parison during inflation is lower than that of extrusion blow molding, and the orientation effect caused by inflation can be saved more, which helps to improve the strength and other functions of the container.
  • 2. The container size (especially the neck rib size) has high precision: it is easier to ensure the uniformity of the container wall thickness as required, and the container specifications are uniform.
  • 3. No joint seam is formed on the container, no trimming is required, and generally no scraps (5% to 30% when scrapping occurs during the extrusion blow molding).
  • 4. A sliding bottom module can be set on the blow molding mold, so the plan flexibility of the bottom style of the container is greater.
  • 5. It is more suitable for molding rigid plastic containers and wide-mouth containers.
  • 6. The gloss of the container is high, and the container made of transparent polymer is always transparent.
