Extrusion Blow Molding Machine Parts Name|What do parts for the machine?

blow molding machine parts name

Why the extrusion blow molding machine can quickly and stably complete the blow molding manufacturing process? Of course, the close cooperation between the parts of the extrusion blow molding machine is indispensable. This blog will introduce the extrusion blow molding machine parts name. And what do parts for the machine?

Here we go!

Before understanding the extrusion blow molding machine parts name, let us first understand how the machine works?
 

Extrusion Blow Molding Machine Manufacturing Process

Molten plastic raw material.

The parison is extruded from an extruder.

The parison enters the extrusion blow molding machine mold.

Cold cutter cutting parison.

Blow pin into the mold and blow.

Mold open.

Cold cutter removes the product.

Extrusion Blow Molding Machine Parts Name And Function

Extruder

Processing of plastic blow moulding raw materials, mainly plasticizing plastics. The core component of the extruder is the screw.

Its working principle is that the pressure and shear force generated by the high-speed rotation of the screw can make the raw materials fully mixed and plasticized. The raw materials used in extrusion blow molding are generally HDPE, PE, PP, and so on. Plasticizing these plastics requires the use of special screws for blow molding.

IKV Screw is an important Yankang extrusion blow molding machine part.

Compared with a traditional screws, the plasticizing efficiency is increased by 1.5 times, and the plasticizing effect is more uniform. Lay a good foundation for the production of high-quality plastic blow molding products.

Die Head

Controlling the parison to extrude uniformly, and controlling the wall thickness of the extrusion parison to be evenly distributed, especially for the production of multilayer extrusion blow molding products, the requirements for wall thickness are more stringent. The wall thickness of extrusion blow molding products is also a headache for many manufacturers of blow molding products.

If you have the same difficulty in blow molding machine wall thickness control, we prepare complete guidance of Blow Molding Wall Thickness Control. Maybe you’ll get helpful something from it.
 

As a blow molding machine manufacturer, Yankang breaks through the traditional die head design, develops a multi-layer die head, and is widely used in large size extrusion blow molding machines. the quality of. Greatly improved the quality of multilayer extrusion blow molding products.
 

Cold Cutter

Apart from cutting off the excess parisons, the product can be taken out after it has been formed.

Sealing Equipment

Pinch sealing at the open end of the parison.
 

Mold Clamping Device

The main function is to open, close, and clamp the mould, and control the movement of the mould on the blow station. Here plays a key role in the hydraulic system of the extrusion blow molding machine.
 

Blow Pin

In this structure, after the parison is extruded, the air is blown into the parison to expand the parison close to the inner wall of the mold.

Pneumatic System

The main control is the operation of the blowing needle, including pre-blowing, air blowing to the parison, and movement of the blowing needle. In addition, to a certain extent, it also controls the cold cutter and wall thickness control of the extrusion blow molding machine.
 

Control Panel

It mainly monitors and controls the running status, electrical system, heating system, temperature, and other aspects of the fully automatic extrusion blow molding machine, controls the step-less speed change of the DC motor of the extruder, the barrel heater, and the mold heater area. Temperature control, real-time monitoring of the working state of the fully automatic extrusion blow molding machine, and the entire molding process of the parison.

The above is the extrusion blow molding machine parts name and function. Understanding the role of the parts of the extrusion blow molding machine can not only better understand the extrusion blow molding machine. At the same time, when the extrusion blow molding machine fails, it can make basic judgments on the problems that arise.
