What are the requirements for the design of the joint mold?
The characteristics of squeezing together are that the two materials flow along the independent flow channels, which meets the exit of the near -mouth mode to jointly squeeze the export mold. When the melts with different streaming properties are squeezed out through a total of a total of the fascia, multi -layer flow will be formed. How to ensure that the pressure of the material in the common runway is consistent. Core issues. The docking of the mainstream tract and the common extrusion runway is the difficulty in processing. In processing, it is necessary to ensure the accuracy of the flow channel, but also consider during the crowding process. During the crowding process, the pressure of the head of the main machine and the co -crossed head may lead to the different pressures of the co -machine head, which may lead to the different pressure of the co -machine head. The overflow problem.
What are the requirements for the design of the joint mold?
In addition, the co -squeezing products with different functions. The processing requirements of plastic mold processing requirements are completely different from the technical indicators reached on the profile.
① When the soft and hard squeeze, the co -squeezing layer is required to have a solid combination with the main material. Therefore, when the design is squeezed out of the machine, the two materials should be ensured that the two materials have sufficient adhesion time in the head of the machine.
② When the new and old materials are crowded, due to the large proportion of the common case, the design of the co -squeezing header should mainly consider the balance between the old streaming and the mainstream lane.
③ When the two -color is squeezed together, the color of the color is thin and uniform. Therefore, when the head design and manufacturing, the binding part of the bastard and the mainstream road is the key. It is necessary to ensure sufficient precision.
