PEEK and Delrin are two popular engineering plastics used in CNC machined components. Although they may appear similar, they serve different operating requirements and design goals. This article compares their properties, machining characteristics, costs, and applications to help you choose the right material. Understanding the Materials What Is PEEK PEEK (Polyether Ether Ketone)…
PEEK has become one of the most widely specified engineering plastics in industries where conventional materials can no longer meet design requirements. As equipment becomes smaller, lighter, and more complex, engineers are increasingly replacing metal components with high-performance polymers in selected applications. At the same time, manufacturing PEEK components is very different from machining common…
Engineers love Delrin (POM) for its ‘plastic steel’ properties, but machining it to tight tolerances is notoriously difficult due to its tendency to deform. At Rollyu Precision, we don’t just cut plastic; we manage its internal stresses. By implementing a rigorous set of internal controls, we consistently hold tolerances within 0.05mm, ensuring part stability from the first prototype to…
POM, also known as Delrin or Polyoxymethylene, is one of the most commonly used engineering plastics in modern manufacturing. This thermoplastic is widely applied in components and manufacturing products because it combines reliable processing capability with balanced material characteristics. Today, these materials can be found in automotive, electronics, medical, and equipment manufacturing. What Is…
In the world of precision manufacturing, Acetal—scientifically known as Polyoxymethylene (POM) and widely recognized as Delrin polyacetal—occupies a unique position. Frequently described as the “bridge between plastics and metals,” polyacetal delrin is a high-performance thermoplastic engineered for high-load mechanical applications where commodity plastics fail. This guide provides a technical deep dive into acetal machining, covering everything from the melting…
Copper alloys used for CNC production are often selected for their fast cutting speeds, efficient chip control, and consistent machining quality. Among them, brass remains a common choice for fittings, electrical hardware, valves, and decorative industrial components. What Is Brass Brass is a copper-zinc alloy used for industrial hardware, fluid system components, electrical…
When machining high-performance engineering plastics, Delrin (POM) stands out for its excellent machinability. But a common question our engineers at Rollyu Precision receive is: “Can you tap Delrin, and will the threads hold up?” The short answer is yes, but if your part requires high load-bearing capacity or frequent disassembly, a standard tapped hole might not be enough. …
Brass and bronze look remarkably similar, but on the CNC machine, they behave worlds apart. Understanding bronze vs brass machining is crucial for optimal production. At Rollyu Precisio, we machine thousands of these copper alloy parts annually. This guide reveals their key machining difference s to ensure your project’s success. What is the Difference Between Brass and…
Phosphor bronze and aluminum bronze are both copper-based alloys, but they are designed for different engineering applications. Phosphor bronze is mainly used for conductivity and fatigue resistance, while aluminum bronze is preferred for strength, wear resistance, and corrosion resistance Quick Comparison: Phosphor Bronze vs Aluminum Bronze Property Phosphor Bronze Aluminum Bronze Electrical Conductivity…
