PE PP PC PET Plastic Injection Molding Machine

ARBUEO A170T PE PP PC PET plastic injection molding machine is a highly efficient plastic product production equipment, suitable for processing thermoplastics such as polyethylene (PE), polypropylene (PP), polycarbonate (PC) and polyethylene terephthalate (PET). The equipment heats the plastic to a molten state, uses the thrust of the screw or plunger to inject the molten plastic into the mold cavity, and obtains the molded product after cooling and solidification.

1. High Efficiency
With a screw diameter of 42mm and a theoretical injection volume of 312cm³, the PE PP PC PET plastic injection molding machine can produce plastic parts quickly. The maximum screw speed of 200rpm further increases production speed. For example, it can complete multiple molding cycles in a relatively short time and produce hundreds of parts per hour. This high productivity is essential to meet the needs of large-scale production.

2. Precise Injection
The injection pressure of 203MPa allows for precise filling of the mold. This produces high-quality products with consistent dimensions and smooth surfaces. In applications where precision is critical, such as the production of electronic components or medical devices, this PE PP PC PET plastic injection molding machine can provide accurate results.

3. Stable Performance
The clamping force of 1700kn ensures stable molding. The tie rod spacing of 470x470mm provides a stable framework for different mold sizes. This allows the PE PP PC PET plastic injection molding machine to produce a wide range of products with consistent quality.

4. Powerful Motor And Heating System
The PE PP PC PET plastic injection molding machine's 23 Kw pump motor power and 11.75 Kw heater power ensure stable operation and fast heating of plastic materials. This reduces production time and energy consumption. The efficient heating system can quickly heat the plastic to a temperature suitable for molding, thereby increasing productivity.

5. Sturdy Structure
The PE PP PC PET plastic injection molding machine has a sturdy structure with dimensions of 5.3x1.3x2.1 m and a weight of 5.8 t. This ensures durability and a long service life. It can withstand the rigors of continuous production and is unlikely to be damaged by frequent use.

6. Continuous Production
The PE PP PC PET plastic injection molding machine's 25 kg hopper capacity and 185 L fuel tank capacity enable continuous production without frequent interruptions. This is especially beneficial for large-scale production runs where downtime costs are high.

FAQ

1. What are the injection molding temperatures of PE, PP, PC, and PET plastics?
The injection molding temperature of PE is usually between 160°C and 280°C; the injection molding temperature of PP is about 200°C to 270°C; the injection molding temperature of PC is higher, usually between 260°C and 340°C; the injection molding temperature of PET is about 250°C to 280°C.

2. Are bubbles easy to be generated during injection molding of PE and PP plastics?
Both PE and PP plastics may generate bubbles during injection molding, which is usually caused by the incomplete discharge of moisture or gas in the material. Therefore, it is necessary to ensure that the material is fully dried before injection molding.

3. What are the common defects in PC plastic injection molding?
Common defects in PC plastic injection molding include shrinkage, surface imaging, gas marks, and weld lines. These defects are usually related to the mold design, injection pressure, and temperature control of the plastic injection molding machine.

4. How to avoid burning during PET plastic injection molding?
Burning during PET plastic injection molding is usually caused by the injection speed of the plastic injection molding machine being too fast or the temperature being too high. To avoid burning, the injection speed and temperature can be appropriately reduced, and the mold design can be optimized to improve exhaust.

5. How does the plastic injection molding machine control the injection volume?
The plastic injection molding machine controls the injection volume by adjusting the rotation speed of the screw and the injection time. This ensures that the amount of plastic injected each time is consistent, thereby improving product quality.

6. What is the effect of the mold temperature of the plastic injection molding machine on plastic products?
The mold temperature of the plastic injection molding machine has a significant effect on the cooling rate, shrinkage rate, and surface quality of plastic products. Appropriate mold temperature can ensure that the product has uniform cooling and shrinkage, thereby improving the dimensional stability and surface quality of the product.

7. How to adjust the injection speed of the plastic injection molding machine to optimize product quality?
The adjustment of the injection speed of the plastic injection molding machine can affect the filling speed and pressure distribution of the plastic in the mold. A faster injection speed can shorten the filling time but may cause bubbles and burning. Therefore, the injection speed needs to be adjusted according to the material type and mold design to optimize product quality.

8. How does the plastic injection molding machine prevent plastic from being trapped in the mold?
To prevent plastic from being trapped in the mold, the plastic injection molding machine usually uses an ejector mechanism and mold design to ensure that the plastic product can be smoothly ejected from the mold. In addition, the injection pressure and temperature control can be optimized to reduce the possibility of retention.

9. Is PC plastic prone to cracking during injection molding?
PC plastic may crack during injection molding, which is usually caused by excessive injection pressure, low mold temperature, or stress concentration in the material. To avoid cracking, the injection pressure and temperature control of the plastic injection molding machine can be optimized, and the mold design can be improved to reduce stress concentration.

10. How to avoid warping during PET plastic injection molding?
Warping during PET plastic injection molding is usually caused by uneven cooling and shrinkage. To avoid warping, the mold design of the plastic injection molding machine can be optimized to improve cooling, and the injection pressure and temperature control can be adjusted to ensure uniform shrinkage.

11. What effect does the clamping force of the plastic injection molding machine have on plastic products?
The clamping force is the pressure applied by the plastic injection molding machine when closing the mold. Sufficient clamping force can ensure that the mold is closed tightly to prevent plastic leakage. However, too high a clamping force may cause mold damage or deformation of the plastic product.
