About plastic bottle molding machine-The difference between two-color pot head and regular scale head?

Figure 1 is a special screw for the striped pot, by which you adjust the spacing of the stripes. The ordinary pot does not have the need for this thread, just the balance of the weight of the various parts of the bucket, so the regular scale head is chosen.

In the plastic industry, there are two types of blow molding machine heads that are commonly used for producing plastic products: regular scale heads and two-color pot heads. The main difference between the two lies in the number of extruders used and the way in which they are configured.

A regular scale head typically uses a single extruder to melt and extrude the plastic material into a parison (a tube-like shape). The parison is then inflated and shaped into the final product. This type of head is suitable for producing single-color products or products with a uniform color throughout.

On the other hand, a two-color pot head uses two extruders to melt and extrude two different colors of plastic material simultaneously. These two streams of molten plastic are then combined in a mixing chamber and extruded through a single die head to form a parison with two distinct colors. This parison is then inflated and shaped into the final product, which can have a two-color or multi-color appearance.

Compared to regular scale heads, two-color pot heads offer greater flexibility in terms of product design and color choices. They allow manufacturers to produce products with intricate designs, patterns, and color combinations that cannot be achieved with a single-color process. This makes them a popular choice for producing high-quality plastic products with unique and eye-catching appearances.

However, two-color pot heads are also more complex and expensive than regular scale heads, and require greater skill and experience to operate. They also require more maintenance and may experience more downtime due to their higher complexity.

In summary, the main difference between a two-color pot head and a regular scale head is the number of extruders used and the way in which they are configured. While regular scale heads are suitable for producing single-color products, two-color pot heads offer greater flexibility in terms of product design and color choices, but come with greater complexity and cost.
