The bottom plate of the mold should have qualified ejector holes

The mold should be equipped with a suitable flange ring and a standard code mold hole should be opened. The thimble should be set so that the plastic part will not be permanently deformed, whitened, and not affect the appearance of the plastic part when it is demolded. The front and back molds and inserts of corrosive materials such as PC, POM, PE need to use 420 steel (such as S136, M300, M310, etc. The steel used for the mirror mold is 420 steel (such as S136, M300, M310, etc. (Equivalent to Japanese Ace Steel) The surface hardness of the materials used in the blank, side nails, back nails, center brackets, and center brackets is not less than HRC60.). The back mold uses general P20 steel (such as MUP, M202, etc. The row position...

The lower the porosity of the part and the better the mechanical properties

Generally, the smaller the resin particle size, the lower the porosity of the part and the better the mechanical properties. From the perspective of convenience and economy, we choose SFX-1 material from Shanghai Chemical Plant. If the resin is processed below the transition point, when the temperature changes around 10°C, the volume of the preform will change by 1%.

The inspection frequency should be strengthened to check whether the packing leaks

During the maintenance of the control valve, focus on eliminating burrs and scars on the valve stem and stuffing box, blinding the valve stem, improving the smoothness of the valve stem, and avoiding moving parts from scratching the packing seal Surface and cause leakage. It is still necessary to continue to analyze and explore in future practice. , Use a pressing tool to compress each circle installed to make the packing uniformly stressed, and the number of packing circles is subject to no exposure.
