With the development of COVID-19 pandemic and life demand, the demand of PET injection molding machine is increasing. There is no doubt that with excellent cost, outstanding quality and production and shipping efficiency, China PET injection molding machine is the best choice for importing. So how to choose the right PET injection molding machine for import? And what should we pay attention to when importing from China? We will give the following 14 tips.
1. Factors affecting the selection of PET injection molding machine
Usually, the important factors that affect the selection of injection molding machine include the weight repetition accuracy of the product, opening position, cycle time, etc. Therefore, the following information must be collected or available before making the selection.
1Product: size (length, width, height, wall thickness), net weight and total weight, etc.
2, material: raw material or granulation and with other and broken material ratio.
2. PET injection molding machine how to choose the model
After obtaining the above information, you can follow the following steps to choose the right injection molding machine.
Decide the machine type and series by product and plastic. When customers choose an injection molding machine, the first step is to determine the structure form of the injection molding machine according to the product taking out direction and mold structure: vertical injection molding machine, angle injection molding machine or horizontal injection molding machine. There is not much difference in the structural form of the injection molding machine of each major manufacturer, and the structural difference is mainly in the clamping structure.
3. injection molding machine clamping force selection
The clamping force is determined by the design structure of the product mold and the plastic to determine the "clamping force" tonnage. The clamping force is an important parameter of the injection molding machine. When the high pressure plastic melt fills the cavity, it will generate a large expansion force in the cavity, making the mold expand along the parting surface. In order not to allow mold expansion, the injection molding machine must provide a force greater than this expansion force to lock the mold, otherwise it will produce the phenomenon of overflow edge running material, this force is the clamping force.
4. According to the mold to choose the appropriate injection molding machine type
-
Connecting column
The inner pitch determines the width of the mold's external dimension. The mold that can be accommodated by the large inner pitch of the guide pillar is also large, and the mold that can be accommodated by the small inner pitch of the guide pillar is also small. The minimum contact area between the mold and the template cannot be less than 60%, and the effective area of the mold cannot exceed the area of the spacing in the connecting column, otherwise it is easy for the engine template to be unevenly stressed, and the product will locally produce flying edges and the template will be easily cracked.
-
Die size
The mold plate is a ductile iron plate supported behind the mold, the mold should not exceed the area of the inner distance of the template. To prevent the mold from bending during injection. The mold is too small and will produce too high bending stress on the template, and even make the template fracture. When injecting thin-walled products, the injection pressure is high, the injection speed is fast and the cycle time is short, the template should be thickened and the reinforced rib plate should be strengthened to increase the stiffness.
-
Mold capacity
The difference between the minimum and maximum mold that can be accommodated by the injection molding machine is the mold adjustment amount of the injection molding machine. The available mold thickness should be larger than the minimum mold capacity, so that the injection molding machine can open and lock the mold. Otherwise, the special work is increased (the effective thread of the guide pillar is increased and the minimum value of the program is changed). If the thickness of the available mold is also larger than the maximum mold capacity, special works should be considered (the frame and guide pillar and their threads should be lengthened, the steel belt of the second plate of the clamping frame should be lengthened, and the maximum value of the program should be changed). However, there is an upper limit for increasing the mold capacity, and the load capacity of the guide column (the maximum mold load weight) should be considered. The maximum and minimum mold capacity of dumpling type injection molding machine are the distance between the movable and fixed plates when the dumpling is straightened and the mold is adjusted to the maximum and minimum, respectively. This parameter determines the size of the mold opening space and the depth of the product. If the mold capacity is large, the depth of the product is deeper; conversely, the depth of the product is shallower. Fully hydraulic large two-plate injection molding machine has larger mold capacity and mold opening stroke than the same level of dumpling type injection molding machine, which is more suitable for deep cavity products and high height products.
5. Seeking PET injection molding machine manufacturer in China
Ways to find a PET injection molding machine manufacturer in China include
-
Online Platforms
