The difference of extrusion blow molding machine & injection blow molding machine

Products
The main difference between extrusion blow molding machine and injection blow molding machine is the type of products they produce. extrusion blow molding machine is often used to make more hollow products such as bottles and other containers. injection blow molding machine is used to form stronger products, which can include LED bulb covers, and other solid products. Extrusion blow molding can create more complex shapes due to how the product is formed. However, injection blow molding is capable of producing high-quality parts in large numbers quickly and accurately.

Molds
For extrusion blow molding machine, there is more design flexibility between the two mold halves, as each mold half forms its own wall shape.
In injection blow molding machine, a high-precision match between the two halves of the mold was required for complete control over the resin flow.
