Coupling injection molding

However, the compression process is probably only accomplished by the core.The complete hydraulic tie rod clamping unit provides users with the most mobile choice.Expansion compression molding and injection-compression molding can change the compression ratio by using the core of the compression mold instead of the rigid clamping unit.However, this is onlyCouplingThis makes sense only in the context of departmental compression.Rely on the point of view of injection molding machine clamping unit.
Since it cannot be marked on its surface, it is in the process of injection molding optical parts.Therefore, the measurement of cavity pressure is limited.But in order to use this tight process parameter to monitor the quality of the coupling, people have adopted a non-contact measurement method using a special measurement pin to measure the cavity pressure.Couple the flow path to the diagram to open up new processing supervision skills.
On the contrary, high-end optical components are not included here.It just so happens that only the highest quality level can be used to produce optical components for practical applications.As far as the prism is concerned, not only its number of shapes and surface layout play a tense role, but the repeatability of production will also greatly affect the internal performance of the product such as internal stress or molecular orientation.Therefore, for a specific example, to evaluate the optical performance of the product during the production process of the coupling, it is even more stressful to only check the shape of the part, or to check the surface of the part with the naked eye, to perform the optical performance measurement.For example, the distortion of the wavefront measured by the sensor can be used as an identification result.Mathematics can be used to deduce a more intense mass function.The expansion-compression molding realized by the clamping unit is more suitable for the production of parts with a stable wall thickness at the cross section.The advantage of this processing method is that stress is not introduced into the produced parts after supplementary molding, because the pressure in the injection process is not applied by the screw but by the clamping, so the pressure in the cavity is symmetrical And the plastic melt can be cooled almost without stress, so that a part with a symmetrical micro-layout can be obtained.
The plastic melt filling process of this method is also the expansion stage completed in a closed mold, which is the same as the standard injection molding method.Probably, when the clamping force is gradually lowered, the screw is opened to a limited and accurately repeatable position.The achievable accuracy of this position control is a key factor in producing parts with reproducible wall thickness.The compression process moves the compression core of the mold to the compression position.
When this position is reached, the compression process begins and the replenishment process is immediately stopped.
