High Precision Double-Notch Sample Cutter for PE-UHMW Impact Testing and FNCT/PENT Sample Preparation Tool

TCQK-1 Double-Notch Sample Cutter Overview

The TCQK-1 Double-Notch Sample Cutter is a high-precision specimen preparation device designed in accordance with international standards. It is specifically used for preparing double-notch samples of ultra-high molecular weight polyethylene (PE-UHMW) molded materials. The equipment complies with technical requirements for environmental stress cracking (ESC) testing and slow crack growth resistance (PENT) testing of polyethylene pipes, making it an essential tool for FNCT sample preparation and PENT notch processing.

This sample cutter is capable of accurately machining standardized notches for use with simple beam impact testing machines, making it an ideal solution for preparing specimens for impact strength evaluation. When used in conjunction with impact testers, it effectively determines the impact resistance of PE-UHMW molded materials under stress conditions, ensuring reliable and repeatable test results.

In addition, the TCQK-1 is also suitable for the standardized preparation of notched specimens required for FNCT and PENT tests. As a professional specimen notching device, it is widely used by polymer research institutes, third-party testing laboratories, and pipe manufacturers for material durability and slow crack growth performance evaluation.

The device is equipped with high-precision guide rails and positioning components to ensure consistent and repeatable notch processing, making it especially suitable for high-efficiency batch preparation of test samples. The operation process is simple and intuitive, with easy tool replacement, making it ideal for both routine laboratory testing and continuous high-throughput use in industrial production. The TCQK-1 Double-Notch Sample Cutter not only significantly improves preparation efficiency but also ensures stable performance and data consistency for various standardized tests, making it the ideal solution for PE material lifetime evaluation and quality control.
