Description
Understanding the Importance of Coplanar Double Notch Preparation
Notch geometry plays a decisive role in impact and fracture-related testing. Even minor inconsistencies in notch depth, alignment, or residual width can lead to significant variations in test results. For PE-UHMW and other engineering plastics, where fracture behavior is highly sensitive to stress concentration points, precise coplanar notch preparation is mandatory using a reliable coplanar double notch machine in the USA.
A professional-grade coplanar double notch device ensures that both notches are perfectly aligned with the specimen centerline, eliminating asymmetry that could distort impact energy absorption results. This level of precision is critical for U.S. manufacturers and laboratories seeking to validate material performance, comply with international standards, and maintain competitive product quality.

TT-DN50 Coplanar Double Notch Machine Designed for U.S. Industry Needs
The TT-DN50 is purpose-built to deliver consistent, high-accuracy notch preparation for demanding testing applications. As a specialized coplanar double notch maker, it enables the preparation of two coplanar notches in a single operation, significantly reducing preparation time while ensuring geometric accuracy.
Unlike conventional notch tools that require multiple passes or manual alignment, this advanced coplanar double notch equipment completes both notches simultaneously, ensuring perfect symmetry and repeatability. This makes it an ideal solution for U.S. laboratories handling high testing volumes or conducting certification-level impact testing.
Applications of the TT-DN50 Coplanar Double Notch Machine
The TT-DN50 is primarily used in conjunction with a 50J pipe Charpy impact tester for evaluating the double-notched Charpy impact strength of PE-UHMW molded materials. This application is critical in the pipe, infrastructure, and industrial polymer sectors, where impact resistance directly influences product reliability and safety.
In addition to Charpy testing, this versatile coplanar double notch tool is also suitable for preparing FNCT and PENT specimens. These tests are widely used in the U.S. to assess slow crack growth resistance and long-term performance of polyethylene materials used in pressure pipes and industrial applications. By supporting multiple testing methods, the coplanar double notch machine in the USA enhances laboratory capability while reducing the need for separate specimen preparation systems.
Compliance Using a Precision Coplanar Double Notch Instrument
The TT-DN50 coplanar double notch machine in the USA is designed to support specimen preparation in accordance with globally recognized standards, including GB/T 18743.2-2022, ISO 21304-2, ISO 9854, ISO 16770-2004, and ASTM F1473. These standards define strict requirements for notch geometry, alignment, and residual width, making precision preparation essential for valid test results.
For U.S. laboratories working in regulated industries, compliance with these standards is a fundamental requirement. A reliable coplanar double notch instrument ensures that specimen preparation meets audit expectations, supports certification processes, and enhances the credibility of reported test data.
Engineering Design That Delivers Unmatched Accuracy with a Coplanar Double Notch Device
At the heart of the TT-DN50 is a unique structural design that guarantees precise alignment between the notches and the specimen centerline. This ensures that both notches are strictly coplanar, eliminating angular deviation that could compromise impact testing accuracy.
The coplanar double notch machine in the USA incorporates an electronic micrometer for real-time measurement of notching depth, providing exceptional control over residual specimen width. This feature greatly enhances the accuracy and consistency of notch preparation, making the TT-DN50 one of the most dependable coplanar double notch devices and pipe testing equipment available for U.S. testing facilities.

Dual-Knife System for Balanced Cutting Performance
One of the defining features of the TT-DN50 coplanar double notch machine in the USA is its synchronized dual-knife cutting mechanism. During the notching process, both knives apply equal cutting force on either side of the specimen, ensuring uniform material removal and eliminating radial deformation.
This balanced cutting approach offers several advantages. It improves notch symmetry, reduces internal stresses introduced during cutting, and extends the service life of the blades. Because the knives are subjected only to axial force without lateral stress, wear is minimized, resulting in longer maintenance intervals and lower operating costs. This makes the TT-DN50 not just a precision coplanar double notch making machine, but also a cost-efficient solution for long-term laboratory use.

Enhancing Laboratory Efficiency and Throughput
In modern testing environments, productivity is as important as precision. The TT-DN50 coplanar double notch machine in the USA enables laboratories to prepare coplanar double-notched specimens in a single operation, significantly reducing preparation time compared to traditional methods.
This efficiency allows U.S. testing facilities to increase throughput without compromising quality. Whether handling routine quality control testing or large-scale certification projects, the TT-DN50 coplanar double notch tool supports faster turnaround times and improved workflow efficiency, making it an essential asset for high-performance laboratories.
Technical Specifications Supporting Reliable Operation
The TT-DN50 coplanar double notch machine in the USA is engineered with technical specifications that ensure consistent performance across a wide range of applications. It features a knife thickness of 0.23 mm with a tolerance of ±0.03 mm, providing precise and repeatable notch geometry.
The blade cutting angle of 14° ±2° ensures clean material penetration with minimal surface damage, while the 19 mm blade width supports stable cutting across different specimen thicknesses. The clamp opening range from 2 mm to 20 mm allows flexible specimen handling, and the supported specimen length range of 80 mm to 120 mm accommodates standard test formats.
With residual width accuracy of ±0.02 mm and notch accuracy of ±0.02 mm, the TT-DN50 delivers the precision required for high-level impact testing. Multiple notch depth options, including 5.5, 4.3, 4, 3, and 1.3 mm, provide versatility for different testing standards and material requirements.
Improving Quality Control in Polymer and Pipe Manufacturing
For U.S. manufacturers producing polyethylene pipes and high-performance polymer components, impact resistance and crack growth behavior are critical performance indicators. Accurate notch preparation directly influences the reliability of these test results.
By integrating a professional coplanar double notch machine in the USA into quality control workflows, manufacturers can ensure that every test specimen meets dimensional standards, reducing variability and increasing confidence in product performance. This leads to more reliable production decisions, fewer test repeats, and improved customer satisfaction.
Supporting Research and Development Excellence
