How Much Blow Molding Machine?

April 29,2022

Generally speaking, the price of blow molding machines ranges from tens of thousands to millions of Yuan each.

Different types of blow molding machines have different prices. In terms of categories, blow molding machines can be divided into three categories: extrusion blow molding machines, injection blow molding machines and special structure blow molding machines. Today, the editor is mainly talking about extrusion blow molding machines. Extrusion blow molding machine is a combination of extruder, blow molding machine and mold clamping mechanism. It consists of extruder and parison die, inflation device, mold clamping mechanism, parison thickness control system and transmission mechanism. The parison die is one of the important components that determine the quality of blow molded products, and the parison thickness control device is used to control the parison wall thickness.

In the commonly used plastic extrusion equipment, the extruder is also called the main machine, and the follow-up equipment plastic extrusion molding machine that is matched with it is also called the auxiliary machine. After years of development, the plastic extruder has been derived from the original single-screw, twin-screw, multi-screw and other models. The main plastic extruder can be matched with various plastic molding auxiliary machines such as pipes, sheets, profiles, granulation, etc. to form various plastic extrusion molding production lines to produce various plastic products.

First of all, I will briefly talk about the advantages and disadvantages of single-screw extruders.

The advantages are: the design of the single-screw extruder is relatively simple, the price is relatively cheap, and it is widely used. Disadvantages: The material conveying of the single-screw extruder mainly relies on friction, which limits its feeding performance, and it is difficult to add powder, paste, glass fiber and inorganic fillers; when the head pressure is high, the countercurrent increases, making the productivity is reduced; the surface renewal effect of the single-screw exhaust extruder material in the exhaust area is small, so the exhaust effect is poor; the single-screw extruder is not suitable for certain technological processes, such as polymer coloring, thermosetting powder processing Wait.

Let’s talk about the advantages and disadvantages of twin screw extruders. Twin-screw extruders are mainly used for extrusion molding of heat-sensitive materials and processing of special polymers. Twin screws for profile extrusion have intermeshing flights, grooves, and operate at lower rotational speeds. Compared with single-screw, twin-screw extruder has much superior feeding and conveying performance, especially those that are difficult to feed and easy to slip, such as fibrous, powdery and oily materials. The material residence time is short and relatively uniform, better mixing and larger heat transfer area, so that the material temperature is well controlled, which is particularly important for the processing of heat-sensitive materials.

When it comes to the price of blow molding machine equipment, it depends on what product you make and what size it is?

 What model and technical requirements are needed? Should the configuration be high or low? Only by giving detailed technical parameters and requirements, can there be an accurate price answer. Configuration is related to price. Buying blow molding machine equipment is the same as buying a computer. The higher the configuration, the more expensive the price.

It can be seen from the above that plastic extrusion molding machinery is one of the widely used models in the plastic processing industry, no matter now or in the future.
The specific price of blow molding machine equipment is difficult to determine. For example, Bekwell can produce dozens of models of blow molding machines.
Judging from the current market conditions, the specific price should be determined according to different equipment models.
