When it comes to blow molding, you probably have an interest in knowing more about the equipment used for it. Blow molding involves forming plastic, hollow parts. Companies use it to make bottles and other objects. A blow molding machine has a similar function to inflating a balloon. The equipment will heat the plastic and shape it to a mold. The right bottle blow molding machine is important to help your facility maximize its profits.

Understanding Molding

Usually, injection molding will melt the plastic and shape it with a mold. This is a preform. The machine will then move the part to a blow molder and put it another mold. Then, the machine will heat the plastic to soften it.

Types of Machines

There are two main types of blow molding machines. The first one is an injection blow molding machine. The second one is an extrusion blow molding machine.

The price of plastic containers is going down because of new technological advances. Companies are working harder than ever to create new containers. However, PET companies also must focus on ways to reduce energy costs. For example, in PET blow moulding, reducing compressed air pressure can reduce your energy costs.

Recirculating the high-pressure air is one of several ways you can reduce the energy usage of your PET blow moulding machine.

Ensuring the Right Air Pressure Configuration

The industrial plastic blow molding machines require a constant supply of compressed air. However, it can be challenging to maintain this constant supply. A PET application must move quickly and blow as many as 2,400 bottles each hour. This high volume can cause the filters and headers to drop in pressure quickly. To compensate for this, the air compressor will often operate at a higher level than needed. Sometimes, PET blow moulding machine manufacturers will need to turn down the production of a moulding machine so that other machines will have enough pressure.

Because of these dynamics, your compressed air system’s design is crucial. Usually, a manufacturer will create two separate compressed air systems. One is for high pressure while the other is for low pressure. This prevents the PET machine from impacting other machinery in the facility. This is the ideal system to reduce your energy usage.

Using Pneumatic Components

Another way to help the air pressure drop is to use localised air receivers. Pneumatic components can further help with this. You should put the receiver tank close to the blow moulder, using large piping to handle the demand. You can retrofit a small pneumatic component, so you optimise the airflow. You will need to consult an expert for this because it can be difficult to..

In the process of injection molding, warping is a common problem that you may have to deal with. You can tell when a product has become warped because part of it has the proper shape, but other parts of it are distorted in a way that a quality item would not be. There are many reasons why this problem may occur. For example, the injection blow molding machinery can be one cause of warpage in injection molding.

Faulty Machinery

Sometimes the injection blow molding machinery may be placing an excessive strain on the part that it is molding. If this is the case, you can try to reduce the amount of pressure on the molded piece. You can do this by reducing the forward time of the screw or increasing the time that the piece is cooling.

Molding and Design

In some cases, a problem with the design of the injection blow molding itself is the issue. Sometimes, the rate of flow from the water flowing through the channels in your molding may be too low. This may cause the part to overheat because it is not properly cooling during the cooling time. Increasing the water flow rate can solve this problem.

In other cases, the mold’s cooling circuits may need balancing. If this is the case, only some of the cavities may warp. Other cavities may continue to function properly. It is also possible that the gates that are on the mold may not be functioning properly. This may be because they are not in the right location or because they were not the proper design in the first place.

Problematic materials

In other cases, the material used to produce the molding may be warping during production. For example, if the designers did not have that material in mind when they created the molding design, the design may not work as originally intended to work. It is also important to use the right type of filling in order to avoid warping problems.
