How to solve the quality failure of the carbon spiral tube production line forming

How to solve the quality failure of the carbon spiral tube production line forming


   The corrugation shape of the outer surface of the carbon spiral tube production line is irregular: the corrugation of the two mold halves does not match, so the running speed of the two mold halves should be re-adjusted to synchronize, or the two mold halves should be aligned after the mold is closed. The two halves of the transmission chain used for mold opening were severely worn, and errors were accumulated during the synchronization operation, which caused the two halves to be misaligned after a period of time during the mold opening operation. The drive chain should be repaired and replaced. If the working speed of the extruder screw is unstable and the amount of extruded melt is inconsistent, the shape error of the formed tube blank is relatively large, and the failure of the screw drive system needs to be repaired. The pressure of the compressed air is unstable, which leads to a large error in the shape of the blown wave shape. The stable air supply pressure should be adjusted. The melting temperature of plasticization is unstable, with different heights. Pay attention to check the temperature control device of the barrel and forming mold to keep the process temperature stable. Wrong choice of raw materials and unreasonable formula combination. Raw materials should be adjusted and formulas should be recombined. The surface of the tube is dull: the melting temperature is low, and the raw material is not completely plasticized. The processing temperature of the barrel and mold should be appropriately increased. The water temperature is too high, so the water temperature should be lowered. The length of the tube blank forming straight section is insufficient, the shaping pressure is small, and the mold structure size needs to be improved.



  The pipe is brittle: the calcium carbonate addition ratio in the raw material formula for forming the pipe is too high or the lubricant addition ratio is unreasonable, the formula should be improved. Appropriately add some acrylate processing aids to the raw materials to increase the gel rate of the melt. If the moisture or impurity content in the raw materials exceeds the standard, the raw materials should be dried or replaced. Insufficient pressure in the forming tube blank mold makes the forming quality of the tube wall poor; the mold structure should be improved. The melt temperature control of the formed tube is unstable, and the high or low melt temperature is easy to make the tube brittle after it is shaped. Pay attention to the temperature of the plasticized melt not to rise and fall to cause excessive temperature difference.

Carbon spiral tube production line

   The adhesion between the inner and outer walls of the carbon corrugated pipe production line is poor: the temperature of the melting material in the forming mold is low, and the temperature of the forming mold should be appropriately increased. If the proportion of lubricant in the raw material is too large, the amount of lubricant added should be appropriately reduced. If the billet is too fast, the two layers of materials are not welded firmly, so pay attention to appropriately slow down the speed of the billet.

  Longitudinal scratches on the inner wall of the pipe: There are scratches on the mandrel forming the inner wall of the pipe, or residual material adheres to the working surface, the scratches should be polished, or the residual material on the working surface of the mandrel should be removed. If there is lubricant sticking, the amount of lubricant added in the raw material formula should be adjusted in time to remove the residue in the sleeve.

  There are cracks or ripples on the inner wall of the pipe: the air pressure used to form the inner wall of the pipe is too high or the air pressure used to form the outer layer is insufficient, resulting in cracks or ripples on the pipe wall. The air pressure used for tube wall forming should be adjusted appropriately. The compression ratio in the forming mold is too small, and the carbon bellows production line causes the joints at the ribs of the shunt cone bracket to have low strength and cracks are prone to appear. The compression ratio of the cavity structure to the melt should be appropriately increased.
