10.How to choose the mold head of a automatic blowing mold machines?

We pay attention to the introduction and training of talents, scientifically regulate the management system, and focus on cultural construction and team cohesion.
1. Determine the type of blow molding machine: The first step in choosing the mold head is to determine the type of blow molding machine you have. There are three main types of blow molding machines: extrusion blow molding, injection blow molding, and stretch blow molding. Each type requires a different type of mold head.
2. Consider the material: The material you will be using for your product is also an important factor in choosing the mold head. Different materials have different properties and require different mold heads. For example, if you are using a high-density polyethylene (HDPE) material, you will need a mold head with a larger opening to accommodate the material's higher melt flow rate.
3. Determine the shape and size of the product: The shape and size of the product you want to produce will also play a role in choosing the mold head. The mold head needs to be able to create the desired shape and size of the product. If you are producing a complex shape, you may need a mold head with multiple cavities or a custom-made mold head.
