4.12 Various pipeline systems should be connected reliably and smoothly without leakage. 4.13 The steam jacket, hydraulic (gas) cylinder, etc. must be subjected to a water jade test. The test pressure shall not be lower than 1.5 times the working pressure. The pressure shall be maintained for 10 minutes without leakage.
4.14 During vulcanization, the heat transfer of the inner wall of the steam jacket should be uniform, and the temperature difference between the crown parts of the two half molds shall not exceed 5℃. 4.15 The pattern and the model must be firmly inlaid. When the pattern width is not more than 12mm, the gap value should be less than 0.03mm. When the pattern width is greater than 12mm, the gap value should be less than 0.05mm. The surface roughness Ra value of the model inner cavity shall not be greater than 3.2um, and the surface roughness Ra value of the pattern shall not be greater than 6.3μum. 4.16
