Injection-molded parts are an indispensable part of modern production and life, occupying a very large share in the plastics processing industry. A high-end injection molding machine is very important due to its complexity, accuracy, manufacturing speed, etc.
Today, I would like to introduce you to the world's top 10 Plastic injection molding machine manufacturers, hoping to help you.

There are many different types of injection molding machines, and choosing the right type can bring greater benefits to your business.
Hydraulic presses have historically been the only option available to molders until Nissei Plastic Industrial Co., LTD introduced the first all-electric injection molding machine in .
Hydraulic machines, although not nearly as precise, are the predominant type in most of the world, with the exception of Japan.
The electric press, also known as Electric Machine Technology (EMT), reduces operation costs by cutting energy consumption and also addresses some of the environmental concerns surrounding the hydraulic press. Electric presses have been shown to be quieter, faster, and have a higher accuracy, however the machines are more expensive.

Servo injection molding machines claim to take advantage of the best features of both hydraulic and electric systems, but in actuality use almost the same amount of electricity to operate as an electric injection molding machine depending on the manufacturer.

In addition, in many cases, they will be classified by the function or application of the injection molding machine, such as our common PET preform injection molding machine, PVC Pipe injection molding machine, etc. Plastic Injection molding machine manufacturers usually prepare or customize corresponding injection molding solutions for you. You can ask your intended manufacturer in detail.
Usually, the important factors that affect the selection of injection molding machines include molds, products, plastics, molding requirements, etc. Therefore, before making a selection, it is necessary to collect or master such information: such as mold size (width, height, thickness), weight, special design, etc.; type and quantity of plastic used (single raw material or multiple plastics); appearance size ( length, width, height, thickness), weight of injection molded products, etc.; molding requirements, such as quality requirements, production speed, etc.
After getting the above information, you can follow the steps below to choose a suitable plastic injection molding machine
-
Model selection
Product and plastic will determine machine type and series.
Since there are many types of injection molding machines, it is necessary to correctly judge which type of injection molding machine or series should be used to produce the product, such as general thermoplastic or bakelite or PET material, single color, double color, multi-color-color, sandwich or mixed color . In addition, some products require conditions such as high stability (closed circuit), high precision, ultra-high injection speed, high injection pressure or rapid production (multi-circuit), and the appropriate series must also be selected for production.
-
Mold size
From the mold size, determine whether the machine's "large column spacing", "mold thickness", "mold minimum size" and "mold tray size" are appropriate to confirm whether the mold can be placed.
The width and height of the mold should be smaller than or at least one side should be smaller than the large column spacing; the width and height of the mold should preferably be within the range of the mold tray size; the thickness of the mold should be between the mold thickness of the plastic injection molding machine.
The width and height of the mold must conform to the minimum mold size recommended by the injection molding machine. Too small is not acceptable.
-
Stroke
The mold and finished product should determine whether the "opening stroke" and "clamping stroke" are sufficient to remove the finished product.
The opening and closing stroke should be at least twice the height of the finished product in the opening and closing direction, and should include the length of the vertical runner; the holding stroke should be sufficient to eject the finished product.
-
Clamping force
The "clamping force" tonnage is determined by the product and the plastic.
When the raw material is injected into the mold cavity under high pressure, the clamping force is generated, so the clamping unit of the plastic injection molding machine must provide enough "clamping force" to prevent the mold from opening. The clamping force requirement is calculated as follows.
The projected area of &#;&#;the finished product in the mold opening and closing direction is derived from the overall dimensions of the finished product.
Clamping force = the projected area of &#;&#;the finished product in the opening and closing direction (cm2) × the number of cavities × the pressure in the mold (kg/cm2).
The pressure in the mold varies with the raw material, generally 350-400kg/cm2.
The clamping force of the machine should be greater than the clamping force. For the sake of safety, the clamping force of the machine usually needs to be greater than 1.17 times of the clamping force.
So far, the specifications of the clamping unit have been preliminarily determined, and the tonnage of the machine has been roughly determined. Next, the following steps must be performed again to confirm which injection unit has a better screw diameter.
-
Shot ratio
Finished weight and number of cavities are used to determine the required "shot volume" and to select the appropriate "screw diameter".
When calculating the weight of the finished product, the number of cavities (how many cavities are in the mold) should be considered; for stability, the injection volume should be greater than 1.35 times the weight of the finished product, that is, the weight of the finished product should be within 75% of the injection volume.
-
Injection quality
Some engineering plastics require higher injection pressure and suitable screw compression ratio design to have better molding effect, so in order to make the finished product injection better, the selection of the screw also needs to consider the required ratio of injection pressure and compression ratio. .
In general, a smaller diameter screw can provide a higher injection pressure.
-
Injection speed
In this case, it may be necessary to check whether the injection volume and injection speed of the machine are sufficient, whether it needs to be equipped with an accumulator, closed-loop control, etc. Screws that can provide higher injection pressures generally have lower injection speeds, and conversely, screws that can provide lower injection pressures generally have higher injection speeds. Therefore, when selecting the screw diameter, the injection volume, injection pressure and injection speed (injection speed) should be comprehensively considered and weighed.
In addition, a multi-loop design can be used to shorten molding time by synchronizing compound actions.
