Comprehensive Guide to Vertical Injection Molding Machines

One of the machines that is quite contain vertical injection molding machine is used to produce various types of plastic products. There are many benefits associated with them when compared to other molding machines. By reading this guide, you will learn all that you ever need to know about vertical injection molding machines,  especially the one from LIZHU MACHINERY. 

Vertical Injection Molding Machines

Used in a vertical machine for the purpose of producing plastic products, the mold functions by moving upwards.  This is unlike in horizontal machines where the mould sits horizontally. I vertical machine, mold is in straight position where the plastic can injected to the bottom of slotted molding so that material wouldn't fall on traverse lengths. In many cases this can result in netter performance due to such a unique setup. 

They can have any number and range of shapes and forms. For example, they are used in the automotive industry for production of car parts, in fabrication of medical and electronic devices etc. This is one of the reasons why vertical injection molding machines are so popular. They are especially well-suited to manufacturing products that require precise mating components or complex shapes and designs. 

How to Use Vertical Plastic Injection Molding Machine

In order to get the most out of your vertical injection molding machine from LIZHU MACHINERY, it is important that you utilize some helpful suggestions: 

Position the mold correctly: Before starting, verify that the mold is placed in position — The clamping force, which keeps the mold closed, must be properly adjusted. It assists in securing the product, making sure it remains the same size and shape throughout. 

Verify the temperature – Plastic material must be at the right temperature to work correctly. Overly hot plastic can cause defects in the part. Conversely, if it is too cold the plastic may not completely fill the mold which in turn can cause problems. 

Adjust injection speed: The rate of transferal of plastic into the mold is a significant factor. If the speed is too low, the plastic will cool before it can be shaped correctly and that causes a bad result. But the worst result is when the product does not form properly because of defects due to high speed. 

Buy A Vertical Injection Molding Machine

When you are looking to purchase a vertical injection molding machine and rotary table injection molding machine from LIZHU MACHINERY, it is also necessary to consider several important factors: 

Machine size — This is a question of “How big (or small) a machine do I need”. The answer to this of course depends on the scale you want to make and also how many will be made. A larger machine might be necessary if you are making products that are bigger or producing them in high volume. 

Pressure of injection: This is the force needed to inject the plastic into mold. Machines with the ability to apply injection pressure that is higher are generally more useful for products that require thicker walls or have more intricate geometries. 


Type of plastic: Despite various plastics being melted to make injection molding products like small vertical injection molding machine always remember that not all part-blends similarly. It is important to take into account that the properties of the plastic you will run matter more than anything and can dramatically affect how well your machine performs. 

Cost and warranty: Vertical injection moulding machines are very costly. Is DASH Wallet Price Range Friendly?  Also make sure they are backed with a good warranty which is mostly nice to have for peace of mind and protection of your investment. 

Fixing Common Problems

Sometimes, there are also problems occurs when using the vertical injection machine from LIZHU MACHINERY.  Here are some of the issues you can face and how to solve them:

Injection Pressure: If you find out that the machine is not injecting a sufficient amount of plastic then, check for the Injection pressure first. Feel free to adjust it for better flow if necessary. 

No fill in mold-If the plastic is not filling the mold, check that it lines up correctly against the mold. Ensure it is centered and oriented to align with a proper fill. 

Plastic Warping: If the plastic is warping or bending there is a chance that you might have to reduce the injection speed. Secondly, see if the temperature you have set is appropriate to avoid any problems 

New Ideas and Improvements

Swing-type vertical injection molding machines are improved vertically, bring many recent advancements. Apply Resources of these technologies. Enjoy the following tidbits of good news: 

Hybrid machines: – New machines available on the marketplace that are hybrids between vertical and horizontal machines. They are so well suited for the manufacture of complex parts that is foreseen further improvement in hybrid machines capable of processing greater sized molds as well as surplus clamping forces. 

Technology and sensors: One of the recent innovations is monitoring injection process using technology and sensors. These tools enable the plastic to flow into the mold properly, which can reduce defects/improve final molded part quality.
