Dongguan real promise is a professional production of beverage EOE EOE, aluminum EOE and iron EOE manufacturer, the company's products, with beautiful fine; design structural precision, good sealing performance, nothing more than diarrhea, not into the air, to ensure product quality and lasting. Here come from Dongguan real promise you briefly explain the system covered the stamping process checks.
1, the metal plate material inspection. To ensure proper use of materials prescribed in the process, each batch sent to the production line of the strip must be visually inspected on the following items: ① Size; ② batch goods packing list; ③ material is consistent with the arts.
2, the outer diameter of the dome. To ensure that the bottom cover stamping process and in accordance with normal production standards, should be in production of an outer diameter of the dome after inspection. ① quality check: bottom at two positions each measurement, bottom outside diameter measurement gauges; ② production line inspection: the outer diameter of the bottom plug, the outer diameter of the dome after checking whether the bottom plug.
3, no rounded edges and rounded edges of the cap height rear side edge height checks. All round cover, including aluminum and tinplate easy-open lid, all openings of each deputy dies, drawn two bottom (class 1 or regulation, after the replacement of mold), buried with Universal measuring instrument, vernier caliper , Universal micrometer around 6:00 bottom points determined not rounded edges (every 60 °), cover edge after highly rounded edges. Rounded edges of the cap is not high control ± 0.05mm, round edge rear edge height control in the range of ± 0.10mm, 0.25mm up any difference between the two points should be considered a serious defect.
4, buried degree examination. For each extracted two deputy dies back, using universal measuring instrument bottom buried, vernier caliper, universal micrometer each only bottom circumference equidistant (120 °) Three measurement, control at ± 0.10mm within the scope of any difference of up to two points should be considered a serious flaw 0.30mm
5, the pressure head with the inspection. Each punch die each take two and bottom separately, using a standard plug indenter were identified for each of the bottom cover, make a record. Experience: Take a standard head upside down on a plate, place the lid countersunk head pressure with the palm slightly 施力平 pressure observed with the situation, if necessary, painted the color of the outer edge of the indenter was observed after contact with the site.
