Challenges in Producing Large PEEK Rods
Producing PEEK rods with diameters exceeding 100mm is notoriously difficult due to several inherent challenges associated with the material and the manufacturing process. Larger diameters are particularly prone to issues such as breakage, residual stress, and inconsistencies, making production a demanding task.
Why Large PEEK Rods Are Prone to Breaking
Residual Stress Development
During the cooling process, larger PEEK rods experience significant temperature gradients between the core and the surface. This uneven cooling can create residual stresses, leading to cracks or breakage in the final product.
Increased Risk of Voids
PEEK's high viscosity in its molten state makes it challenging to fill larger molds or extrusion dies evenly. This can result in internal voids or defects, which compromise the rod's structural integrity and make it susceptible to breakage under stress.
High Processing Temperatures
PEEK requires precise control of high processing temperatures and pressures. For larger rods, maintaining uniform heat distribution is more difficult, increasing the likelihood of weak points that can lead to fractures.
Prolonged Cooling Times
The cooling process for large-diameter PEEK rods is slower, and rapid cooling attempts to save time can result in material stresses that eventually cause breakage.
ARKPEEK's Capability: Producing PEEK Rods Up to 200mm
While many manufacturers struggle to produce PEEK rods beyond 100mm due to these challenges, ARKPEEK has developed proprietary techniques and advanced manufacturing processes that allow us to produce high-quality PEEK rods with diameters up to 200mm.
How ARKPEEK Overcomes the Challenges
Optimized Temperature and Pressure Control: Our state-of-the-art equipment ensures uniform heat and pressure distribution, even in large-diameter rods.
Specialized Cooling Techniques: By implementing controlled cooling processes, we minimize residual stresses and ensure the structural integrity of the final product.
Rigorous Quality Assurance: Every large PEEK rod undergoes thorough inspection to detect and eliminate defects such as voids or uneven density.
With our expertise, ARKPEEK is setting a new benchmark in the production of large-diameter PEEK rods, delivering reliability and performance where others fall short. If you require PEEK rods for critical applications, our ability to produce up to 200mm diameter rods ensures that your needs are met with precision and quality.
