Injection although the importance of the housing industry has been more and more people know, but has not yet reached its height, so the status is not fully straighten, policies cannot be fully implemented, the strength of the support is insufficient, strength is insufficient, so we want to in the use of performance, how to improve the injection molding shell use below small make up to tell you about performance.
1, the hardness
Given in addition to corresponding relationship with the intensity, hardness is closely related to the injection molding casing wear resistance, impact toughness, reduction of area and elongation indicators such as licensing conditions, as much as possible to improve the hardness, forging die hardness and red hardness is an important performance of die materials, injection molding shell work under high temperature should be able to keep its shape and size does not change.
2. Impact toughness, reduction of section and elongation
Since the choice of impact toughness index of forging injection shell material is closely related to the property of forging load, for the injection shell used in impact load equipment such as hammer and screw press, if the impact toughness of forging injection shell material is low, the injection shell may crack and be scrapped. In this condition, it is necessary to choose the forging injection molding shell material with high impact toughness.
3. Tensile strength and yield strength
Different types of injection shells focus on the specific mechanical properties required by forging injection shell materials. At the same time, the mechanical properties of room temperature should not be taken into consideration and the more important performance indicators of actual working temperature should not be ignored. The pursuit of a high index that is blindly divorced from the reality should be avoided by all means.
