Is one of the many molds produced by our company, its use is very good, then we know that the production of PVC plastic steel profile extrusion mold manufacturers tell you the factors affecting the service life of aluminum extrusion die!

What factors will affect the service life of the aluminum extrusion die?PVC plastic steel profile extrusion mold manufacturer told you as follows:

Today PVC plastic steel profile extrusion mold manufacturer with everyone to explore the impact of aluminum extrusion die service life are what factors? Interested partners come together to watch it!

1.PVC plastic steel profile extrusion mold manufacturer introduced to the overall mold inevitably exists concave fillet, when the fillet radius is less than 2 mm or deep and narrow die chamber concave fillet, or concave fillet processing left a knife mark, these are prone to cause stress concentration, and will thus cause cracking.

2. In order to reduce the ejection force of the blank within the tolerance range of the blank and to reduce the time that the blank stays in the mold cavity, the mold needs to be appropriately sloped, for example, the head of the bell-shaped shell products with the same diameter at the upper end of the dimensions than the lower end of the dimensions of the size of the larger by about 0.1 mm. For example, the upper end of the same diameter of the head of the bell-shaped shell is about 0.1mm larger than the lower end. This will reduce the ejection force from the mold and reduce the strain on the cavity surface of the concave mold. Do not have the reverse slope, that is, inverted tip, otherwise it will reduce the quality of the blank and thus reduce the service life of the mold, and in serious cases, it will cause stuffy material, resulting in damage to the mold.

3.PVC plastic steel profile extrusion mold manufacturer told us that the mold guiding device is also very important, it can ensure the mold in the work of the relative position of the mold parts of the accuracy, to prevent uneven wear and tear of the mold, reliable guiding structure to prevent the convex die and concave die nibbling each other is very beneficial to the die with a small gap is particularly important. Otherwise, it will produce bias load mold nibbling caused by early failure of the mold.

4. Choose a reasonable gap between the convex and concave molds, not only can effectively improve product quality, but also have a certain impact on the life of the mold. Too small a gap will produce mold gnawing, too large a gap, not only affect the product coaxiality, but also due to bias load so that the convex mold bending, resulting in the impact of convex mold life.

5.PVC plastic steel profile extrusion mold manufacturers introduced to the mold processing accuracy, decided to mold manufacturing process after a polishing process. Good or bad polishing will not only directly affect the service life of the mold, and the finished product surface finish, dimensional accuracy will have an impact.
