Selection criteria for injection mold materials

Selection criteria for injection mold materials, choosing materials correctly is not a simple task, because many factors need to be considered to keep the cost as low as possible. Perfect materials do not exist, in most cases, it is necessary to balance between different properties, and it is necessary to clearly know which properties are 'must have' and which properties are 'best to have', so we Factors must be considered when selecting materials: operating temperature, hardness, impact resistance, tear resistance, chemical resistance, ultraviolet radiation resistance, r-ray resistance.
