Rockwell Hardness Tester for Plastics, Rubber, and Polymers

DESCRIPTION / TECHNICAL SPECIFICATIONS

When testing soft materials, precision is everything. This Rockwell Hardness Tester is specifically designed to meet the unique challenges of measuring the hardness of hard plastics, hard rubbers, synthetic resins, and a variety of other non-metallic materials. Unlike standard metal testers, this instrument is engineered to deliver accurate, reliable results without damaging or piercing the specimen surface, making it an indispensable tool for polymer manufacturers, R&D facilities, and quality control labs across multiple industries.

The core advantages of this tester lie in its motorized testing method and appropriate Rockwell scale selection. The entire testing cycle—including the loading, dwelling, and unloading of the test force—is fully automatic. This motorized system guarantees a consistent application of force every time, eliminating operator-induced variables and errors, which is critical when working with polymers where results can be highly influenced by testing technique. By utilizing specialized Rockwell scales such as HRE, HRL, HRM, and HRR, along with large-diameter ball indenters, this machine ensures a representative measurement of the material's hardness, not just its puncture resistance.

Though designed for plastics, its flexibility is extensive. This instrument is also highly effective for testing soft metals like aluminum, tin, and copper, as well as soft steel and friction materials. This makes it a versatile solution for facilities that handle a wide range of softer materials. Operation is straightforward, with test results clearly displayed on a large, easy-to-read precision dial indicator, providing quick and reliable readings even in a busy production environment.

Built for durability and reliability, this machine is a workhorse asset for your laboratory or production floor. Each unit comes equipped with the necessary standard accessories, including various sizes of ball indenters, large, medium, and V-shaped testing tables, and standard hardness blocks to ensure continuous calibration and accuracy. Trust your soft material quality control to an instrument that is purpose-built for the task.
