Multi-Drop Hot Runner Injection Mold    

Why is a multi-drop hot runner injection mold system called that? The term hot runner is used because some parts of this system are physically heated so that it is easier to transfer plastic in a molten state from the machine into the mold cavities. If we compare this to the cold runner system, then the main difference between the two is simply that the cold runner system is not physically heated that is the hot runner system is in fact physically heated.

As mentioned above there is a cold runner system as well for the injection molding, so why do we need a hot runner system? The multi-drop hot runner injection mold system uses a heated manifold and runners which ensures a higher quality product to be manufactured.

And this is the main theme of the article, to understand how the hot runner system ensures high-quality product manufacturing. what exactly is a multi-drop hot runner injection mold system? How does it work and what are its advantages that ensure high-quality products?

What is a Multi-Drop Hot Runner Injection Mold System?

A multi drop hot runner injection mold system uses a heated manifold two-turn plastic into a molten state and keeps it Molten throughout the process. this is a type of injection molding system. In this system The molten plastic is injected into a number of mold cavities at the same time, to produce The plastic product. the molten plastic travels through the machine through internal channels that are called runners. Hence, the whole system is called the hot runner injection mode system.

The two main factors that a very important in the system are the temperature flow and the molten plastic flow pressure control. The temperature controller is very important. It maintains the temperature of all the components in the machinery to the desired temperature.

The temperature has a direct effect on the flow of the molten plastic as well as the degree of molten in the plastic. Therefore, maintaining the right temperature is very important in a multi-drop hot runner injection mold system.

The degree of pressure with which the molten plastic flows is related to the channels it flows through. Any variation in the pressure will cause damage to the product, therefore it is very important to maintain the pressure.

Features and Advantages of a Multi-Drop hot runner Injection Mold System

Now, we will look at the features of a Multi-Drop hot runner Injection Mold System. It serves as an advantage for manufacturers and ensures higher quality products.

Time-saving

It has smaller channels and therefore, it takes less time to run each cycle. You get your ready-made product from the machine. Thus, you don’t need to do the extra manual work of making the surface smooth cutting excess, or other stuff. The cycle itself is also shorter compared to the cold runner system which further decreases the cycle time.

No waste produced

Further, hot runners can be beneficial in reducing wasted plastic during high-volume shoots. Because cold runners are unheated, the channel needs to be larger. Thus more plastic needs to be shot during each cycle. If you are producing a large number of parts while iterating to get the design correct you could easily run up the cost of plastic above the cost of a hot runner assembly.

In a multi-drop hot runner injection mold system, a great benefit is that there is little to no waste. Manufacturers who manufacture large volumes of products will greatly benefit from this. In the cold runner systems where there is no heating, the channels or runners are much bigger. Bigger channels mean that larger amounts of plastic are used during each cycle. Making large amounts of different products will easily cost you a lot on the amount of plastic you use. However, in the hot runner Injection Mold System, there is a lot less waste done, close to non.

Precise and good looking products

The multi-drop hot runner injection mold system has a lot of advantages to offer when it comes to very challenging detailed geometry in the products. These types of products require very less error because there is a lot of detailing in them.

For such a product A very undisturbed even flow of the molten proper plastic is required. Therefore, the hot runner system is the best option. As it heats up the plastic throughout the process. A very even flow of molten plastic is produced that enters the mold cavity. Thus, resulting in the production of very good quality products.

If we compare this to the cold runner system, we will get a very uneven flow of molten plastic and the detailing on the product will not be visible. Therefore, a very low-quality product will be produced.

Automation in process of injection molding

There is an increase in the demand for automatic systems in the industries, including injection molding systems as well. As we go in the future, newer and more advanced technologies are being used in every industry.

Likewise, in the injection molding industry, the Multi-Drop hot runner Injection Mold System allows you to atomize your molding process. This system is very flexible and there is no danger of uncoordinated machinery.

The multi-drop hot runner injection mold system can be used to manufacture parts like, phone cases, Bottle caps, and any type of projects that require the manufacturing of large volumes of inexpensive plastic parts.

It is a much better manufacturing plastic products process compared to the cold runner system. Many industries are upgrading to this technology to improve the quality of their products and work efficiently.
