The transfer basket is frequently used in life, and it can be used to store vegetables, fruits, sundries and other things. Transfer baskets are used frequently. In order to meet demand, the production of transfer baskets must be increased. At this time, a high-frequency, high-speed machine for producing transportation crate basket injection molding machine is needed.

What are the elements and principles of injection molding of the transportation crate basket injection molding machine?

(1) Molding material: molding shrinkage characteristics, flow characteristics, thermal sensitivity, mechanical characteristics of resin, etc.

(2) Molding machinery: mechanical injection pressure, injection volume, injection rate, plasticization ability, clamping force, mounting plate size, etc.

(3) Forming mold: dimensional accuracy and surface treatment of mold cavity, runner system design, cooling system design, ejector structure design, mold material, etc.

(4) Speed: filling speed, screw speed, pressure holding speed, mold opening and clamping speed, ejection speed, etc.

(5) Pressure: filling pressure, screw back pressure, holding pressure, mold opening pressure, ejection pressure, etc.

(6) Temperature: sol temperature, mold temperature, ambient temperature, baking material temperature, etc.

(7) Time: filling time, holding pressure time, cooling time, mold opening and clamping time, etc.

(8) Position: filling position, transfer holding position, storage position, loosening and retreating position, residual material amount, opening and locking position, ejection position, etc. ,

Explanation of commonly used terms related to transportation crate basket injection molding machine:

1. Mold clamping pressure: The motor provides power and the mold clamping unit is used to lock the mold to ensure the smooth filling and pressure holding of the melt in the mold cavity.

2. Cavity pressure: the pressure formed during the melt flow during molding. Depends on the pressure of the end of the injection and the pressure holding period. This pressure should not be greater than the clamping pressure, otherwise the PL surface of the product will be out of the way.

3. Injection pressure: The pressure required for melt flow during molding. This pressure is powered by the motor and applied to the sol in the metering chamber through the injection unit and the screw.

4. Holding pressure: The production of this pressure is the same as the production of injection pressure, but the effect is different. Its function is to compensate for the shrinkage of the melt in the cavity, so as to achieve the purpose of ensuring the appearance and size of the product.

5. Back pressure: In the process of plastic melting and plasticization, the melt continuously moves to the front end of the barrel, and more and more, gradually forming a pressure, which pushes the screw back. In order to prevent the screw from retreating too fast and to ensure uniform compaction of the melt, it is necessary to provide a reverse pressure to the screw, and this reverse pressure to prevent the screw from retreating becomes the back pressure.

6. Screw.

7. Shrinkage and post-shrinkage: After filling, the volume of the plastic product is reduced due to thermal expansion and contraction and internal molecular reorganization.
