Plastic Machining

Teflon is technically a thermoplastic, yet it behaves unlike any other polymer in its class—it cannot be melt-processed by conventional methods due to its extreme melt viscosity. That contradiction is exactly what makes PTFE so valuable across aerospace, chemical processing, and medical industries. Below we break down Teflon’s molecular structure, explain why it resists both […]

The trucking industry is categorized as heavy-duty, and it requires the utmost accuracy, dependability, and creativity to ensure that goods are moved appropriately. PAI Manufacturing is at the nexus of these efforts as it leads the industry in innovation for heavy-duty truck parts manufacturing. In this article, we analyze how PAI Manufacturing leverages its matchless

PTFE’s low surface energy makes it naturally slippery, but that same property creates a challenge when you need a truly smooth, defect-free finish on machined parts. Polishing Teflon requires the right abrasives, controlled pressure, and careful temperature management to avoid smearing or deforming the soft material. This guide covers mechanical, chemical, and thermal polishing methods

Holding tight tolerances on PTFE is difficult because the material creeps under stress, expands with temperature changes, and springs back after machining. Standard tolerances for PTFE parts range from ±0.001″ to ±0.005″, but achieving the tighter end of that range requires deliberate strategies around stress relief, fixturing, and tool selection. This guide covers the practical

In working with plastic materials, ABS is mainly known to be flexible and extensively utilized in many sectors. But can ABS be machined using a CNC machine? What do you need to know beforehand? This guide highlights the CNC machining of ABS plastic, its peculiarities, possible issues, and how to deal with them. It doesn’t

Machining Teflon PTFE: The Complete Guide to CNC Processing, Challenges, and Applications Polytetrafluoroethylene (PTFE), widely known by the DuPont brand name Teflon, is one of the most demanding yet rewarding engineering plastics to machine. Its unmatched chemical inertness, near-zero friction coefficient, and broad temperature tolerance make it indispensable for seals, bearings, gaskets, and insulating components

CNC machining of acrylonitrile butadiene styrene (ABS plastic) is standard in modern manufacturing because of its flexibility in making final components, robustness, and cost efficiency. However, the results are optimal only when the machining parameters, mainly feeds and speeds, are well understood. These factors significantly affect surface texture, shape accuracy, and overall efficacy. This guide

Nylon is synthesized from petrochemical-derived monomers—primarily adipic acid and hexamethylenediamine—that undergo condensation polymerization to form the tough, flexible polyamide chains the material is known for. Understanding these raw-material building blocks matters because resin chemistry directly affects machinability, moisture absorption, and mechanical performance in finished parts. This article breaks down nylon’s key ingredients, synthesis routes, and

PTFE (Teflon) sheets are soft, slippery, and prone to deformation under cutting forces—making them one of the trickiest plastics to machine accurately. Success depends on the right combination of sharp tooling, controlled feed rates, and proper workholding. This guide walks through every step of CNC milling Teflon sheets, from material fixturing to finish-pass strategies, so

Nylon is one of the most widely used plastics in machined components, found in everything from bushings and gears to structural brackets and electrical insulators. Its combination of high tensile strength, low friction, chemical resistance, and light weight makes it a practical alternative to metal in many mechanical applications.
