During the operation of the hollow board production line, if cracks are found in the produced hollow boards, it is necessary to immediately identify the cause of the cracks and make corresponding adjustments to restore production to normal. Below, we will introduce the reasons that may cause cracks in hollow boards, as well as corresponding solutions and preventive measures.
1、 Reasons for the appearance of cracks
Raw material issues: Low quality plastic pellets, excessively damp or aged materials can all lead to fragile finished products.
Temperature control: Insufficient or excessive temperature during the extrusion process can affect the flowability and forming of the material, which may lead to cracking.
Mold issues: Defects, wear, or blockage in mold design can lead to uneven stress during extrusion, resulting in cracks.
Uneven cooling: Insufficient cooling system or uneven flow may cause cracks in the hollow board due to uneven shrinkage during the cooling process.
2、 Solution to Cracks
Adjust raw materials: Ensure the use of high-quality, compliant plastic pellets. If necessary, dry the materials to avoid the influence of moisture on them.
Temperature optimization: Adjust the temperature setting of the extruder according to the material characteristics to ensure that the melt remains in a suitable flow state and can evenly fill the mold.
Mold maintenance: Regularly inspect and maintain molds, and replace or repair them as necessary to ensure their good performance during the production process.
Cooling adjustment: Check the flow rate and uniformity of the cooling system to ensure that each part has the same cooling effect and avoid cracking of the hollow board due to excessive temperature difference.
3、 Methods to prevent cracks from appearing
Training operators: Regularly train operators to increase their understanding of equipment, raw materials, and production processes, and improve the standardization of production operations.
Regular equipment inspection: Regularly maintain and inspect the equipment to ensure the stability and reliability of the hollow board production line.
Improve production process: Optimize the production process to ensure quality control at every node, thereby reducing the occurrence of defective products.
