How to choose the servo injection molding machine that suits you ?

Dec 05, 2019

The purchase of servo injection molding machine is not a small investment. Buying too large an injection molding machine is a waste. Buying too small is not suitable. Therefore, choosing an injection molding machine that meets the needs of the customer's own products has become the most concerned content for each buyer. Of course, the merchant recommends the appropriate injection molding machine to the buyer, and introduces the buyer to how to choose the injection molding machine that meets the needs of the product. The first lesson for buyers.


In order to understand more systematically the various procedures of choosing servo injection molding machine, I write the following content and one of them in detail.


When choosing a servo injection molding machine, the criterion of selecting the injection weight alone is oversimplification, and it is not reasonable to use only the clamping force. Therefore, we must combine the two to make a reasonable choice.


Determination of injection weight of servo injection molding machine

    The injection weight is an important parameter of the injection device of the servo injection molding machine. It is the most commonly used parameter when selecting a servo injection molding machine, and it is also a key parameter. It is expressed in grams (g) or ounces (oz) (Note: 1 gram = 0.035 ounces, 1 ounce = 28.35 grams). Although this parameter is simple and easy to understand, it is also easy to be misunderstood. The reason is very simple. When the plastic is selected, the weight of the plastic part can be determined. Therefore, they can easily choose the machine based on the injection weight. In fact, the definition of injection weight refers to the maximum plastic injection weight that the injection device can reach when the injection screw makes a maximum injection stroke under the condition of air injection (without injection into the mold); this parameter reflects to a certain extent The processing capacity of the injection molding machine is measured; it can be measured or calculated from the theory (theoretical value and the measured value will have a certain degree of difference).
