Manufacturing Process of Screws and Nuts from PVC-U Hexagonal Bars<\/strong><\/h5>
<\/strong><\/div>

The production of screws and nuts from AKU\u00ae-DUR PVC-U hexagonal bars takes place in several precise steps to ensure high quality and mechanical stability. Various machining processes such as turning, milling, and thread cutting are used. <\/p>

<\/p>

Material Selection and Cutting<\/strong><\/h5>
<\/strong><\/div>

Starting material:<\/em>
The production begins with the selection of high-quality PVC-U hexagonal bars in the appropriate diameter and length dimensions. These bars are characterized by high dimensional stability, chemical resistance, and good processability. <\/p>

Cutting:<\/em>
The hexagonal rods are sawed or cut to the appropriate length according to the desired screw or nut size. Precise dimensional accuracy is ensured to guarantee uniform further processing. <\/p>

Turning and Milling of Screw Heads and Nuts<\/strong><\/p>

Shaping of Screws:<\/em>
\u2022 The cut PVC-U rod is clamped in a lathe to prepare the screw head and thread profile.
\u2022 The head shape can be designed as hexagonal, flat head, or round head as needed.<\/p>

Processing of Nuts:<\/em>
\u2022 Nuts are machined from the hexagonal rod using a milling machine.
\u2022 Subsequently, a hole is drilled for the internal thread.<\/p>

Thread Cutting or Forming<\/strong><\/p>

Cutting the External Thread (Screws):<\/em>
\u2022 The external thread of the screw is applied using a thread cutting tool or thread turning process.
\u2022 Precise control ensures a clean and dimensionally accurate thread structure.<\/p>

Cutting the Internal Thread (Nuts):<\/em>
\u2022 The internal thread is cut in the pre-drilled nuts using a tap, ensuring a perfect fit with the screw.
\u2022 Alternatively, the thread can be manufactured by milling.<\/p>

Final Processing and Quality Control<\/strong><\/p>

Smoothing and Deburring:<\/em>
\u2022 After thread production, screws and nuts are carefully deburred to remove sharp edges.
\u2022 Surface finishing can be applied to reduce friction and increase durability.<\/p>

Quality Inspection:<\/em>
\u2022 The manufactured screws and nuts are checked for dimensional accuracy, thread precision, and mechanical load capacity.
\u2022 In addition to visual inspection, mechanical load testing may be performed.<\/p>

<\/p>

Conclusion:<\/strong><\/h5>
<\/strong><\/div>

The manufacturing process of screws and nuts from AKU\u00ae-DUR PVC-U hexagonal rods combines precise mechanical processing with high material quality.<\/p>

Thanks to the easy formability of PVC-U, robust and durable fasteners can be produced that are chemically resistant, corrosion-free, and lightweight – an ideal alternative to conventional metal connections.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
