Primul, observe the appearance quality. Appearance quality is one of the most intuitiv indicators to judge mold quality. You can check if the surface of the mold is smooth, flawless and scratched, the edges of the mold are clear, flat, the presence of foreign objects, etc. At the same time, it is important to check if the mold's logo and manufacturer's information are clearly identiable and că ei urmări sursa și calitatea a mucegaiului .
În al doilea rând, măsura the geometry of the mold. Precise dies should have geometric dimensions that match the design drawings. You can use tools such as rigers, iarpers, height gauges to measure the size of the mold, inclusiv length, width, height, diameter, aperture, aperture, etc. Comparing the measurement results with the dimensions required by the design, if there is a large abatere, may mean that the machining precizie of the mold is not high or there is a problem.
The assembly and motion of the mold are then tested. Deasamblare și asamblare matriță la verificare că fiecare component of the mold fits well and is flexibil. Pay special attention to the mold guide parts, sliders, pushrods and other key parts of the assembly and movement, they direct affect the accuracy and stability of the mold. You can also check if the mold's movement is smooth, stable, and dacă matrița produce anormal sunet sau vibrații în timpul utilizarea a matriței.
La the same time, the mold material is checked. The quality of cemented carbide mold is closely related to the quality of the selected material. The composition and performance of the material can be understood by examining the material certificate of the mold or the relevant inspection report. For metal materials, metalographic tissue observation, hardness testing, etc. can be efectuat to determine the quality of the material. Cimentat carbură matrițe poate de asemenea fi testat pentru uzură rezistență și temperatură ridicată proprietăți pentru a asigura ei satisface cerințele dorite .
