The most easily damaged component in the entire PP (polypropylene) hollow board production line is usually the "mold". The design and manufacturing of molds have a crucial impact on the quality, efficiency, and cost of hollow board production. The following is a detailed analysis of the causes and influencing factors of mold vulnerability.
1. Mold structure and working principle
The mold is used in the hollow board production line to shape the melted PP material into the desired hollow board structure. It extrudes molten plastic through an extruder, cools and shapes it through a mold. Any damage to the mold may directly affect the quality of the product and the continuity of production.
2. Reasons for vulnerability
Temperature changes: Molds often need to withstand alternating high temperatures and rapid cooling during operation, which can lead to material fatigue and increase the risk of mold damage.
Material wear: The extruded molten PP material will experience friction with its surface when passing through the mold. Long term friction may cause wear on the surface of the mold, affecting the quality of the molding.
Cooling system issue: The cooling system of the mold is crucial for stabilizing the temperature. If the cooling is not in place, it may cause the mold to overheat, affecting the fluidity and cooling speed of the plastic, thereby causing deformation or damage to the mold.
Material quality: If the PP material used contains impurities or other additives, it may corrode the mold during the extrusion process, leading to a shortened lifespan of the mold.
3. Impact of mold damage
Product quality decline: Damage to the mold will directly affect the thickness, density, and surface smoothness of the hollow board, thereby reducing the overall quality of the product.
Production interruption: Once the mold is damaged or malfunctioning, the production line must be shut down for repair or replacement of the mold, resulting in a loss of output.
Rising maintenance costs: Frequent mold damage can lead to increased maintenance costs for businesses, including repair costs and production losses.
4. Other vulnerable components
In addition to molds, there may be other vulnerable parts in the PP hollow board production line, such as:
Extruder screw: If not handled properly or using inferior materials, the extruder screw may experience wear, breakage, and other issues.
Cooling system: including cooling water pumps and cooling pipelines, etc. If these components leak or block, it will affect the system's cold and hot balance, thereby affecting production.
Cutting tools: Tools used for cutting finished products may also experience wear and tear after prolonged use, which can also affect the cutting quality of hollow boards.
