61 Idle running test
6 1. 1. Before the idle operation test, the following items should be checked:. Measure the distance between the hot plates when the hot plates of the vulcanizer are opened: b. Check the parallelism between the lower plane of the beam and the upper plane of the base according to the requirements of Article 4.3. 6.1.2 The number of mold opening and closing in the idle operation test shall not be less than 10 times, and the following items shall be checked during the test: L. The plunger should be able to stay on any position and move in the opposite direction during the mold opening and closing process: b. During operation, the plunger should be able to rise and fall flexibly without obstruction and without scratches on the surface; measure the noise sound pressure level during the operation of the vulcanizer, 6.2 Load operation test
6.2.1 "Only after the idle operation test is passed can a continuous load operation test of not less than 4 fives be carried out, 6.2.2 Load operation The following items should be checked during the test: 1. Check the total pressure of the chemical machine and the pressure in the capsule (or air bag) through instruments; 2. All systems should be connected and there should be no blockage or leakage; 3. There should be no leakage in the water cylinder, plunger, hot plate and other components; 4. Measure the temperature of the plane and outer surface of the hot plate installation mold. 5. Inspection regulations
1 Factory inspection
, 1. Each product must be inspected before it is shipped out. 7.12 Quality inspection shall be carried out in accordance with Article 4104.116.1 and shall comply with its provisions. The product can only be shipped out after passing the inspection of the inspection department of the manufacturer of the lock. The product quality certificate and main measurement data shall be attached when it is shipped out.
7. 2 Type inspection
7.2.1 Type inspection shall be carried out in accordance with the requirements of the standard and shall comply with its provisions. 7.2 In any of the following cases, the machine shall be subject to type inspection: new products and old products are transferred to production for trial production and adjustment; when the product has major changes in batch structure, material and process; when the product has stopped production for more than three years and resumed production; when normal production is carried out, at least one machine shall be inspected annually; 7.23 When the random inspection fails, two more machines shall be inspected. If there is still one machine that fails, the cause shall be found out and the batch of products shall be inspected one by one.
