How much do you know about the plastic injection molding machine?

The injection molding machine has been the main molding equipment for the production of thermoplastic or duroplastic plastics in various forms of plastic products using plastic molding tools. It can be divided into vertical, horizontal, and fully electric. The injection molding machine can heat the plastic and exert high pressure on the molten plastic to eject and fill the molding cavity.

Choose the right type: select the right injection molding product and the right plastic to determine the model and series.

As there are many types of injection molding machines, it is necessary to determine at the outset correctly from which injection molding machine or series the product is to be produced, such as general thermoplastics or bakelite raw materials, or PET raw materials. Colour, two-colored, multi-colored, intermediate or mixed, etc. In addition, some products require conditions such as high stability (closed circuit), high precision, ultra-high fire rate, high gun pressure, or fast production (multi-loop), and the appropriate series must also be selected for production.

What should we consider when using the injection molding machine?

Can be deposited: To assess whether the "large column space", "thickness", "minimum shape size" and "matrix size" of the injection molding machine are suitable to confirm whether the mold can be used.

The width and height of the shape shall be less than or at least one size smaller than the inner distance of the large column;

The width and height of the mold should be within the size range of the mold plate;

The thickness of the mold shall lie between the mold thickness of the injection molding machine;

The width and height of the shape shall be the minimum size recommended by the injection molding machine and shall be too small.

What should be considered after using the injection molding machine?

Finally, the "closing force" of the injection molding machine is determined by product and plastic.

When the raw materials are injected into the molding cavity with high pressure, a molding support force is generated. Therefore, the injection molding machine closure unit must apply sufficient "closing force" to prevent the tool from opening. The calculation of the tensioning force requirement is done as follows:

Calculate the projected area of the finished product in the direction of the switch form from the appearance size of the finished product;

Lowering force = projected area of the finished product towards switch shape (cm2) x number of mold cavities x pressure in form (kg/cm2);

The pressure in the form varies with the raw materials, generally 350'65374400kg/cm2 for raw materials;

The tensile strength of the machine must be greater than the tensile strength and, for safety reasons, the tensile strength of the machine is generally one,17-fold the tensile strength;

At this point the specifications of the closing unit have been provisionally defined, the tonnage of the model has been roughly defined and then the following steps have to be taken to confirm which screw diameter of the injection unit is best suited.
