Vertical VS Horizontal Injection Molding Machine: Which One is More Suitable for You

Kebida

Horizontal injection molding machines and vertical injection molding machines are important machines for production in today's society, and have a wide market and development prospect, and a very large number of excellent injection molding machine manufacturers have emerged. There is no doubt that horizontal injection molding machines and vertical injection molding machines have huge differences visible to the naked eye, then they are also very different in terms of functions and areas of expertise. Today we will discuss their differences.

 

The difference between horizontal injection molding machine and vertical injection molding machine

  • The difference in terms of appearance

Vertical injection molding machine machine covers a small area, but the height is higher generally vertical injection molding machine height are more than 3 meters. Horizontal injection molding machine is the opposite, horizontal injection molding machine covers a large area, the height is shorter.

  • The difference in weight

Vertical injection molding machine weight is about 1-6 tons. The weight of horizontal injection molding machine is more than 10 tons.

  • The difference of molding products

Vertical injection molding machine molding products are smaller like connectors, plugs, wire plugs and other small precision injection molding products. The horizontal injection molding machine produces large products such as shoe soles, teeth, bowls, bottles and other large injection molding products.

  • The difference between injection molding methods

In fact, the vertical injection molding machine and horizontal injection molding machine injection principle is the same, but the vertical injection molding machine is vertical injection molding machine, horizontal injection molding machine is horizontal injection. The difference between the two is not much, but in the face of liquid raw materials, affected by gravity, the horizontal injection molding machine is more difficult.

 

Advantages of horizontal injection molding machine

  1. Since the main frame of the main machine is low, there is no height restriction on the installation plant

  2. If the product can be dropped automatically, the product can be formed automatically without using robot

  3. Horizontal injection molding machine has low body, feeding becomes easy and maintenance is simpler

  4. The mold should be installed as a crane

  5. With more than one side by side arrangement, the molded products are easily collected and packed by conveyor belt

 

Advantages of vertical injection molding machine

  1. The injection unit and clamping unit are located on the same vertical center line, and the mold is opened and closed in the up and down direction. The floor space is only about half of that of the horizontal machine, which translates to about twice the productivity in terms of floor space. 

  2. Vertical injection molding machine is easy to realize insert molding. Because the surface of the mold is facing upward, it is easy to put the insert into position. If the lower mold plate is fixed and the upper mold plate is movable, the combination of belt pulling conveyor and robot can easily realize fully automatic insert molding.

  3. The weight of the mold of vertical injection molding machine is supported by the horizontal mold plate for opening and closing action, so it will not happen that the mold plate cannot be opened and closed due to the forward collapse caused by the gravity of the mold similar to the horizontal machine. It is conducive to maintain the accuracy of the machine and the mold permanently.  

  4. Vertical injection molding machine can take out each plastic cavity by a simple robot, which is conducive to precision molding.

  5. The general clamping device is open around the mold, easy to configure all kinds of automatic devices, adapt to the complex and delicate products of automatic molding.  

  6. The vertical injection molding machine's pulling belt conveying device can be easily installed in the middle of the mold, which is convenient to realize automatic production of molding.  

  7. Comparable to horizontal injection molding machine, vertical injection molding machine is easier to ensure the consistency of resin fluidity and mold temperature distribution in the mold.  

  8. Equipped with rotary table, moving table and tilting table, it is easy to realize insert molding and in-mold combination molding.

  9. Vertical injection molding machine for small batch trial production, the mold structure is simple and low cost, and easy to unload.  

  10. Vertical injection molding machine has withstood the test of many earthquakes, and the vertical machine has better seismic resistance compared with the horizontal machine because of its low center of gravity.

 

When to choose vertical injection molding machine

  • When you design a new product, you should choose a vertical injection molding machine if you have the following needs.

  • You do not need to drop the part from the mold for disassembly. Gravity will not help the part fall out of an open mold.

  • You need to run concurrent operations, such as using two lower halves and one upper half in tandem.

  • When parts need to be inserted or overmolded to enhance the functionality and/or visual appeal of the product. The inserts used for insert molding will be held in place by gravity, which makes the operation easier to merge.

  • When part design and molding operations require more consistent resin flow within the mold and more accurate temperature distribution.

  • When your operation requires a smaller injection molding machine that takes up less floor space. Vertical injection molding machines typically have half the footprint of horizontal machines.

  • When your design requires less pressure and clamping force. Gravity will help hold the mold together during the injection molding operation.

 

When to choose a horizontal injection molding machine

Horizontal plastic injection molding machines are generally more common. So it's generally easier to find the right horizontal injection molding machine manufacturer and supplier to provide the appropriate service and support.

  • Your molded parts need to be manually removed from the mold by a human operator or a robotic arm. And gravity can also help to dislodge parts from the mold. A horizontal injection molding machine may be a better choice.

  • You need to make multiple parts for each molding cycle, with multiple part cavities in the mold. A horizontal injection molding machine can be a better match

  • Your parts or certain design features are cylindrical in shape.

  • You need a large number of parts in a production run

  • Your part design does not require insert or overmolding.

All in all, the horizontal injection molding machine is better suited for larger production lines, and he brings an important foundation for efficient production.

 

Conclusion

Whether it is a vertical or horizontal injection molding machine, they both have suitable areas and not small differences.

If you want a more suitable injection molding solution, then you should look for the most suitable injection molding machine manufacturer. Contact us or check our horizontal injection molding machine products to get the latest consultation.
