Manufacturing Process & Quality Checks

• The process begins with the careful selection of high-grade raw materials such as polyethylene for HDPE pipes and polyvinyl chloride (PVC) for UPVC pipes.
• These materials are sourced from certified suppliers to ensure purity, quality, and compliance with industry standards to customers.
• The raw materials are then mixed with necessary additives to enhance properties like strength, flexibility, UV resistance, and durability.

  • The extrusion process is the core of pipe manufacturing. The prepared raw material is fed into an extruder, where it is melted at controlled temperatures to achieve a uniform consistency.
    • For UPVC and HDPE pipes, the material passes through a specialized die to form the required pipe shape and size.
    • For DWC pipes, a dual extrusion process is used to create the double-wall structure, which consists of a smooth inner layer and a corrugated outer layer for added strength and flexibility.

• After extrusion, the hot pipes are passed through a calibration sleeve to achieve precise dimensions and shape.
• The pipes are then transferred through a cooling system, typically involving water baths or spray cooling, to solidify and retain their structure.
• This rapid cooling ensures dimensional stability and prevents deformities, resulting in strong, durable pipes.

• Once cooled, the pipes are marked with essential details like brand name, pipe size, pressure rating, manufacturing date.
• This ensures traceability and helps customers easily identify the product specifications during installation and inspection.

• The pipes are cut to the desired lengths using high-precision cutters.
• Finishing processes are applied to smooth any rough edges and prepare the pipes for easy installation.
• Each pipe is inspected to confirm that it meets the required length, thickness, and quality standards.

• At JK Polyextrusion, quality control is a critical step. Each batch of pipes undergoes rigorous testing to ensure compliance with ISO, ISI, and other relevant standards.
 Testing procedures include:
• Pressure Testing: To verify the pipe’s ability to withstand high pressures.
• Impact Resistance Testing: To ensure pipes can endure physical stress without cracking.
• Chemical Resistance Testing: Particularly for HDPE and UPVC pipes, ensuring durability in
corrosive environments.
• Dimensional and Visual Inspection: Confirming pipes meet exact specifications and have no visible defects.

• Dimensional and Visual Inspection: Confirming pipes meet exact specifications and have no visible defects.

• Once the pipes have passed quality control checks, they are securely packaged to prevent any damage during transportation.
• Pipes are bundled or coiled (in the case of smaller diameters) and labeled according to size and type, ready for distribution.
• JK Polyextrusion ensures efficient logistics, delivering products to clients promptly and in
optimal condition.

• Throughout the manufacturing process, JK Polyextrusion adheres to environmentally responsible practices by reducing waste, optimizing energy use, and recycling materials
whenever possible.
• We prioritize sustainability to deliver high-quality pipes that not only meet industry demands but also align with our environmental commitments.
