Medical injection molding molds are usually relatively strict, injection molding production and processing requires finding experienced manufacturers and paying attention to 11 details.
If the injection molded part is multi-colored, try to simplify the structural characteristics. Ensure that the more complex parts are coordinated and the total width of non-transparent ribs is as small as possible, between 0.5- 0.6mm to avoid shrinkage.
Injection molding mold accessories need to be symmetrical in front, back, left, and right, and left and right mold symmetrical.
The front mold of the injection molding needs to rotate 180 degrees and cannot be moved.
The interval between injection-molded company products needs to be based on the interval of the plastic machine barrel nozzle. Some dual-color injection machines have adjustable barrel nozzle spacing, and some do not.
Injection molding has two separate ejection systems, and the top rod is also two separate ones. The two company products of the front mold are also the same, and the guide pillars are the same and rotate in relation to each other. Do not make parallel surface relationships.
The guide pillar plate of the injection molding can only be calibrated with torsion springs and cannot be forcibly calibrated with screws because the rear mold needs to rotate.
The edge lock of the injection molding needs to be around the mold management center and must be symmetrical for the left and right molds, otherwise it will not be good when the rear mold rotates 180 degrees and is different from the front mold.
If the interval between the adhesive injection of the injection molding and the nozzle of the medical plastic machine is different, the top pinhole needs to be made into a waist shape because the interval between the plastic machine top pins cannot be adjusted. Pay special attention that most injection nozzles of domestic brand dual-color injection machines cannot be adjusted.
Pay special attention to the position of the plastic machine parallel surface nozzle brought by the user, whether it is the X axis or the Y axis, to determine the reasonable layout of company products.
The injection molding inlet and outlet water positions need to be on the top and bottom, and the inlet and outlet of each circulating water system need to be on the same surface and cannot seep into the sky. The water output is on the ground side because the front mold needs to rotate 180 degrees. Be particularly aware that the size of the mold accessories cannot exceed the relative height of the stainless steel water tank that the plastic machine cannot handle, otherwise the water cannot be transported.
The medical injection molding needs to rotate 180 degrees when it is just starting to inject to be well-molded and in the correct position for easy removal.
