Custom Precision PC & Acrylic Tubes

Standard manufacturing tolerances for extruded plastic tubes typically range from ±0.15mm to ±0.25mm for outer diameter (OD) and wall thickness, depending on the material and profile size. For high-precision applications, EXLONG can achieve tight industrial tolerances down to ±0.1mm through advanced inline sizing and vacuum calibration systems.

The choice depends heavily on your application’s mechanical and environmental demands. Polycarbonate (PC) is highly recommended for industrial and high-impact environments due to its superior shatterproof durability and heat resistance. Acrylic (PMMA), on the other hand, offers unmatched optical clarity, a more premium surface gloss, and exceptional UV weatherability, making it the ideal choice for outdoor displays and architectural branding structures where yellowing must be prevented.

Yes, absolutely. EXLONG specializes in complex non-standard geometries. Our technical tooling capabilities allow us to custom-extrude specialty formats including square profiles, hexagonal pipes, spiral twisted decorative tubes, and inner/outer ribbed shapes tailored precisely to your engineering blueprints.

Yellowing is primarily caused by prolonged UV exposure and thermal degradation of the polymer chain. EXLONG prevents this by utilizing premium, virgin optical-grade PC and PMMA resins embedded with specialized UV stabilizers and anti-yellowing agents. This ensures our clear and frosted tubes maintain high light transmission and structural aesthetics in both outdoor retail and architectural applications.

Yes. We utilize advanced co-extrusion technology to merge different colors or materials into a single, seamless tubular profile. A common application is our dual-color PC tubing, which integrates a frosted/opal diffusion face with a solid black or white functional tracking base, ensuring structural rigidity and zero light leakage for streamlined product assembly.

Yes. All custom plastic tubes extruded by EXLONG are manufactured using 100% pure, virgin resins that fully comply with strict global environmental standards, including RoHS and REACH regulations. We provide material certification to guarantee safety and compliance for international supply chains.

Maintaining flawless optical quality is our priority. We achieve scratch-free surfaces by utilizing mirror-polished extrusion dies, specialized soft-touch pulling equipment, and automated inline masking films. Additionally, all finished tubes are individually packed in protective sleeves or specialized crating to ensure they arrive at your facility in pristine condition.

We do. Yes. We offer precision custom-cutting for long tubes, ranging from 10 mm to 6,000 mm in length. We also offer in-house secondary fabrication such as CNC machining, hole drilling, punching, chamfering and slotting to suit your specific technical drawings.

For standard sizes, we can utilize our extensive library of existing molds to eliminate tooling costs. For custom shapes or non-standard dimensions, technical tooling design and sample production typically take 10 to 15 days. Minimum Order Quantities (MOQs) are flexible and vary depending on the profile weight and specific material requirements. Please contact our sales team for a precise quote.
