GBPI GBH-S – Universal Material Testing Machine (Dual-Column Heavy-Duty UTM)

The GBPI GBH-S is a high-capacity, heavy-duty dual column universal material testing machine developed for comprehensive mechanical testing of rigid plastics, high-strength composite laminates, rubber elastomers, textiles, metallic foils, and industrial containers. Built in strict accordance with international mechanical testing protocols including ASTM E4, ASTM D638, ASTM D882, ISO 527 (Parts 1, 2, 3), and ISO 178, this dual-column universal testing machine (UTM) provides testing laboratories with uncompromising frame rigidity and broad force versatility.

High-force mechanical characterization is essential for validating the tensile yield point, ultimate tensile strength, flexural modulus, and compression deformation of engineering polymers and heavy industrial packaging. Operating as a dual column universal material testing machine, the GBPI GBH-S utilizes a high-rigidity structural frame driven by dual synchronized precision preloaded ball screws and an industrial digital AC servo drive system. This configuration guarantees exceptional crosshead axial alignment and eliminates frame deflection even under maximum 20 kN (20,000 N) loading conditions.

Multi-Range Class 0.5 Metrology & Fixture Versatility

The GBH-S accommodates interchangeable high-precision load cells ranging from 3,000 N up to 20 kN with Class 0.5 measurement accuracy (±0.5% of indicated value). A spacious test area allows quick mounting of specialized fixtures including mechanical wedge grips, hydraulic tensile clamps, 3-point and 4-point flexural bending anvils, compression platens, and puncture fixtures.

Intelligent Software & Real-Time Data Acquisition

The machine communicates directly with dedicated PC workstation software that captures high-speed force and displacement data. The platform automatically calculates tensile strength, yield stress, percentage elongation at break, flexural modulus, and compressive yield points.

The software features multi-curve comparison, customizable test certificate generation, user permission management, and tamper-proof electronic record archiving compliant with modern ISO 17025 and industrial quality assurance protocols.

Advanced Drive Dynamics & Operator Safety

Operator security is paramount when conducting high-force testing routines. The GBH-S incorporates hardware safety interlocks including adjustable optical displacement limit switches, automatic load cell overload detection at 110% of rated capacity, and a panel-mounted emergency stop button. The vibration-free servo mechanical system ensures high dynamic response during high-speed tensile elongation as well as low-velocity creep and relaxation testing, making the system an indispensable asset for rigorous material research.
