Detailed Manufacturing Process Flow for PVC Rigid Sheet (Vacuum Forming)

The production of high-quality សន្លឹក PVC រឹង (ទម្រង់បូមធូលី) is a sophisticated process involving precise control over material selection, extrusion, calendering, and finishing. This meticulous approach ensures the final product meets stringent performance and aesthetic requirements for vacuum forming.

1. Material Preparation and Compounding:

• Resin Selection: High-grade PVC homopolymer resin (e.g., K-value 60-70) is selected for its optimal molecular weight and processing characteristics suitable for rigid applications.
• Additives Blending: The PVC resin is compounded with a carefully formulated mix of additives. This includes heat stabilizers (e.g., calcium-zinc systems) to prevent degradation during processing, lubricants (e.g., paraffin waxes, stearic acid) to improve flow and reduce friction, processing aids (e.g., acrylic modifiers) to enhance melt strength and surface finish, impact modifiers (e.g., MBS) for improved toughness, and often UV stabilizers or colorants as per specific application requirements.
• Homogenization: All components are thoroughly mixed in high-speed blenders to ensure a homogeneous dry blend, which is crucial for consistent sheet quality.

2. Extrusion or Calendering:

• Extrusion (Typical Method): The compounded PVC dry blend is fed into a twin-screw extruder. The material is melted, homogenized, and continuously pushed through a flat die to form a sheet. Precise control of temperature profiles across different zones of the extruder (typically 160-190°C) is maintained to prevent degradation and ensure optimal melt viscosity.
• Calendering (For Thicker Sheets/High Volume): In some cases, for very thick sheets or high-volume production, the melted PVC compound might be fed into a series of heated rollers (calenders). These rollers progressively reduce the material thickness to form a continuous sheet of desired gauge and surface finish. This method allows for excellent gauge control and surface quality.

3. Cooling and Sizing:

• Cooling Stack: The hot sheet exiting the die or calender rollers passes over a series of highly polished, temperature-controlled cooling rolls. These rolls rapidly cool the sheet, solidifying it and imparting a smooth, consistent surface finish. The temperature gradient is meticulously controlled to prevent internal stresses and warpage.
• Gauge Control: Advanced laser or beta gauge systems continuously monitor the sheet thickness, and feedback loops automatically adjust the die gap or roll pressure to maintain precise dimensional tolerances (typically ±5% of target thickness).

4. Edge Trimming and Winding/Sheeting:

• Edge Trimming: The edges of the sheet are trimmed to remove any irregularities, ensuring uniform width. These trim materials are often collected and recycled back into the process after appropriate re-pelletizing, contributing to sustainable practices.
• Surface Protection: For certain applications, a protective film (e.g., PE film) may be applied to one or both sides of the sheet to prevent scratches and surface damage during transport and handling.
• Cutting/Winding: The continuous sheet is either cut into specific lengths (sheeting) or wound onto large rolls, depending on customer requirements for downstream vacuum forming processes.

5. Quality Control and Testing Standards:

Throughout the process, rigorous quality control measures are implemented. Finished sheets undergo comprehensive testing to ensure compliance with international standards such as:

• ISO 9001:2015: For Quality Management Systems, ensuring consistent product quality.
• ASTM Standards: For material properties like tensile strength (ASTM D638), impact strength (ASTM D256), density (ASTM D792), and dimensional stability.
• REACH & RoHS Compliance: To ensure adherence to chemical substance regulations and restrictions on hazardous substances, particularly for export markets.
• FDA Compliance (for medical/food contact grades): Specific formulations meet FDA regulations for direct and indirect food contact or medical device components, where applicable.

The service life of a សន្លឹក PVC រឹង (ទម្រង់បូមធូលី) component, when properly designed and applied, can exceed 10-20 years, even in challenging environments, primarily due to its inherent resistance to degradation from chemicals, moisture, and impact.
