The lifespan of precision plastic molds is directly related to the quality of the molds themselves, which is a consensus among everyone. However, the lifespan of precision plastic molds is also related to other factors. The quality of precision plastic molds is mainly related to design, material selection, processing, and assembly. From a design perspective, the main considerations are:

The quality of precision plastic molds is mainly related to design, material selection, processing, and assembly. From a design perspective, the main considerations are:
(1) The size of the mold frame and the wall thickness of the mold cavity; the relationship between lifespan and manufacturing costs, and the impact of the size of the injection molding machine on investment and production costs.
(2) The strength of embedded parts and their reliability in placement.
(3) Try to avoid individual parts or certain positions in the mold cavity from becoming weak links.
(4) Guide pillars play a very important role during the mold moving process, so their strength and wear resistance should be considered. Other material selections, processing, and assembly mainly consider the contradiction between cost and quality, which will not be elaborated here. Below we mainly discuss the relationship between the clamping mechanism and the lifespan of precision plastic molds.
(5) Before opening the mold for precision plastic molds, due to the locking force not being released yet, especially during overload, the core has not yet recovered, and the plastic has already cooled, resulting in significant friction between metal and plastic that exacerbates core wear.
(6) When opening the mold, due to the sudden release of locking force in elbow-type mechanisms, vibrations occur that can exacerbate damage to some stressed components.
