Generally speaking, most customers who have been engaged in the injection molding industry for many years have the ability to judge and select the appropriate high-speed injection molding machine for production.
However, in some cases, the customer may need the manufacturer's help to decide which machine specification to use, or even the customer may only have a product sample or concept, and then ask the manufacturer whether the machine can be manufactured or this model is more suitable.
In addition, some special products may need to be matched with special equipment to improve production efficiency. It can be seen that how to determine the appropriate high-speed injection molding machine production is an extremely important issue.
The important factors that usually affect the selection of ejectors include molds, products, plastics, molding requirements, etc. Therefore, the following information must be collected or provided before selection: size (width, height, thickness), weight, special design, etc., the plastic used Type and quantity (single material or multiple plastics); finished product appearance size (length, width, height, thickness), weight, etc.; molding requirements, such as quality conditions, production speed, etc.
Suitable injection machine:
1. Select type: model and series are determined by product and plastic. Due to the wide variety of injectors, it is necessary to determine which high-speed injection molding machine or series of products should be used to produce this product, such as general thermoplastics or PET raw materials, which are single color, heavy color, multi-color, sandwich or mixed color. or.
In addition, some products also require conditions such as high stability (closed loop), high precision, ultra-high-speed shooting speed, high shooting pressure, or rapid production (multi-loop), and the appropriate series must be selected for production.
2. Can be placed: Determine whether the "column distance", "mold thickness", "minimum mold size" and "template size" are appropriate from the mold size to confirm whether the mold can be placed.
The width and height of the mold can be smaller than or at least one size smaller than the internal distance of the large column; the width and height of the mold are preferably within the size range of the mold; the thickness of the mold should be between the thickness of the high-speed injection molding machine.
The width and height of the mold must meet the minimum mold size recommended by the injection molding machine. Removable: Determine from the mold and the finished product whether the "mold opening stroke" and "supporting mold stroke" are sufficient to take out the finished product.
The mold opening stroke must be at least twice the height of the finished product. In the direction of opening and closing the mold, the length of the gate should be included; the moving distance of the supporting mold should be sufficient to eject the finished product.
Lockable: The product and plastic determine the "locking force" tons. When the raw material is injected into the cavity under high pressure, a force to support the mold is generated. Therefore, the clamping unit of the high-speed injection molding machine must provide sufficient "clamping force" to prevent the extension of the mold.
