In general there are three main types of blow molding. Right Mould Open 10. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding ISB a preform.
Blow molding BrE moulding is a manufacturing process by which hollow plastic parts are formed. It is also used for forming glass bottles. Extrusion stretch blow molding.
There are three main stages in the injection moulding cycle. Left Blow Pin Out 7. Right Blow Pin Out 15.
The open design allows you to integrate the control of virtually any process variable. Blow Molding Process The first step involves mixing melting and pushing plastic extrusion to form it into a tube called a parison that will be used to make the part. On the basis of these two methods to carry out.
Once a parison of sufficient length is. The Overview of all the parts of Moulding Machine is shown in the above diagram under Segment A. The mold has two halves that are closed around the molten parison.
This tube is referred to as a parison. Service and Parts available 247 for Blow Molding Machines. The reciprocating screw rotates by means of motor and the reciprocating motion is provided by hydraulic system.
The two most common types of blow molding are extrusion blow molding and injection blow molding with many variants related to handling of the parison and molds. Blow molding is a simple five-step sequence. The parison die head is the heart of the blow molding machine and as such due care should be given in handling the same during operation dismantling cleaning or assembly.
It generally consists of. The bigger the part the higher the advantage for the blow molding process. Uniloy is a global leader in blow molding technologies and the only blow molding machine manufacturer to offer four unique blow molding technologies as well as blow molds and associated tooling.
When comparing injection molding to blow molding for a thermoplastic rubber hollow part blow molding has the edge. Single to 3-parison die head configurations.

The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass. Size limitations on parts which can be made by blow molding. The figure shown below illustrates the complete Blow Molding Process in A B and C segments.
The MACO Compact offers the advantage of a totally integrated package that includes state of. When you need parts or service you can call our service line. BLOkon 01 Manual Page 6 of 34 B INTRODUCTION -BLOkon is a complete proven reliable control system for Blow Molding Machine-System consists of three units1 Display unit 2 Input Output drivers 3 Transformer CVT.
Right Carriage In 12. Blow Molding Process-Pressure Distribution Applications Differences etc. The blow molding process begins with melting down the plastic and forming it.
A mold is used to make the part shape you desire. Understanding the role of the parts of the extrusion blow molding machine can not only better understand the extrusion blow molding machine. Blow molding is an umbrella term for forming hollow plastic parts by inflating a molten plastic tube or parison until it fills a mold and forms the desired shape.
Figure 317 depicts an extrusion blow molding process in which a cylinder of semi-molten plastic called a parison is extruded downward between two open mold halves. The Finish on the edges of the die rings and materials is very important. When stage 3 is completed the mould closes again and the cycle starts over again.
Right Carriage Out 13. Uniloys core technologies include UR reciprocating screw series blow molding machines industrial blow molding machines UAI accumulator head and. The cooling time and the demolding time which impact the cycle time.
High change-over costs from one part to another. 32 kg 70 lbshr maximum output. The Feed from the Extruder is given as an input into the Blow Molding Machine.
Extrusion blow molding and injection blow molding. Overview of Blow Molding. Blow-Moldable Polyolefins and Applications.
At the same time when the extrusion blow molding machine fails it can make basic judgments on the problems that arise. There are three main types of blow molding. This is based on.
All of our blow molding machines are made to last are easy to use and offer quality production. The main difference between the two lies in the preparation of the blank and then the blow molding process is the same. The original finish on these components should not be damaged.
Additional applications for schools. The above is the extrusion blow molding machine parts name and function. Stage 1- INJECTION OF THE PLASTIC MELTS INTO THE MOULD.
Extrusion blow molding is recognizable by the hollow tube that is extruded from the machine to create the parts. It can be used to blow mold almost any type of plastics that can be injection molded. Blow molding also known as blow moulding in the United Kingdom is a molding process in which heated plastic is blown into a mold cavity to create a hollow object.
Up to 24 cash back Blow molding troubleshooting guide Introduction This guide indicates possible causes and corrective actions for problems typically encountered in the blow molding process. Extrusion blow molding injection blow molding and injection stretch blow molding. The MACO Compact machine control system is a scalable system designed to meet even the most demanding blow molding applications.
Stage 1 injection followed by stage 2 holding pressure and plasticating and finally stage 3 ejection of the moulded part. Right Blow Pin In 14. The feed acts as the melted plastic and it is to be passed through.
It is not however intended to provide a com-plete listing of all blow molding challenges and problems. The part volume and the number of cavities. 38mm diameter 15 reciprocating screw extruder.
For additional troubleshooting information contact your Dow. This is caused by the large number of molds and core pins required. Right Mould Close 11.
A hollow mold then closes around the parison and cycles to the blow station. Explanations of the parts of Injection Moulding Machine are as follows. Blow molding is a special type of molding process however that leverages the properties of traditional glassblowing.
Versatile smaller machine with up to 3-parison die heads for smaller blow molded parts or single head for up to one-gallon size parts. Scalable Open Machine Control System for Blow Molding. ParisonTubular shape of hot plastic Mold.
Plastic barrel hollow blow can be divided into two categories. When at the blow station the parison within the mold is molded through utilizing air pressure while another parison is being extruded from the machine. Extruder updown H PRECAUTIONS To prevent damage from human and machine please obey the.
Think of it like inflating a balloon inside of a water bottle. The feed from the Extrudes. Reciprocating Screw Blow Molding Machine.
