Material testing is the foundation of quality, safety and performance across virtually every manufacturing industry. By measuring how materials behave under tension, compression, torsion, fatigue, impact and hardness, manufacturers can verify that their products meet design requirements, comply with international standards and perform reliably in real-world conditions. Whether you produce metal components, springs, automotive parts, rubber seals, plastic pipe or fasteners, selecting the right testing machine is essential to protecting your brand and your customers.
At CHENJI we supply precision electronic universal testing machines and a full range of material testing equipment used by laboratories and production lines worldwide. The sections below organise our machines by industry and application, with direct links to the machine that does the job, so you can move from your product to the correct testing solution in a few clicks.
Metal Testing
Metal testing covers tensile strength, yield point, elongation and compression testing of steel and non-ferrous metals used in construction, machinery and structural applications. A computer-controlled electro-hydraulic servo universal testing machine such as the WAW 1000 kN / 2000 kN hydraulic universal testing machine handles reinforcing bar and heavy sections, while the electronic series covers smaller specimens. For room-temperature tensile testing to ISO 6892-1 and ASTM E8 these frames are the standard choice.
For axial fatigue testing of metals and components, see the resonance fatigue testing machine, which runs at 50-250 Hz to build S-N curves efficiently.
Spring Testing
Spring testing covers load-deflection, fatigue and stiffness testing of compression, tension and torsion springs used in automotive and industrial products. The WDW-100/200/300/500 kN electronic universal testing machine is widely used for load-deflection work, and the smaller WDW-5 5 kN single column universal testing machine suits light springs and wire. Fatigue life of springs is measured on the resonance fatigue testing machine.
Automotive Testing
Automotive testing verifies components, fasteners, bushings and suspension parts for durability and safety in vehicle assembly. Tensile and compression testing of metal parts runs on the WAW-300 kN hydraulic universal testing machine, bolt and fastener performance is checked on the JWL-30 bolt anti-slip tightening test machine, and long-life components are qualified on the resonance fatigue testing machine.
Rubber Testing
Rubber testing covers tensile, tear and compression-set testing of rubber and elastomeric materials in seals, gaskets and hoses. Electronic universal testing machines with the correct grips run these tests, and the hardness of rubber and plastics is measured on a portable Leeb hardness tester or a bench hardness tester where a shore or micro-hardness method applies. The rubber testing category lists the recommended machines and grips.
Pipe & Plastic Testing
Pipe and plastic testing covers burst pressure, tensile and dimensional analysis of plastic pipes, fittings and polymer products. Melt flow behaviour of thermoplastics is measured on the CXNR-400D MFR/MVR melt flow rate meter to ISO 1133, GB/T 3682 and ASTM D1238, while thermal behaviour is studied on the CDSC-500A differential scanning calorimeter. Pipe and fitting strength is tested on a universal testing machine with the appropriate fixtures.
Metallographic & Hardness Testing
Metallographic and hardness testing examines microstructure and measures hardness to evaluate material quality and heat-treatment results. Hardness is measured with Vickers and automatic turret Vickers hardness testers, a Brinell hardness tester or a portable Leeb hardness tester, while microstructure is prepared on the MPS-2B grinding and polishing machine and examined on a metallographic microscope.
Impact, Torsion & Specialised Testing
Impact and pressure testing measures the energy absorbed when a notched specimen is broken, using the CXJU-22M Izod impact testing machine or a digital display impact testing machine. Torsion testing measures the shear behaviour of wire, shafts and springs on a torsion testing machine, and dynamic mechanical behaviour is studied on the microcomputer-controlled electro-hydraulic servo dynamic testing machine. Browse the impact and pressure testing and torsion testing categories for the full range.

Free Engineering Tools
Planning your next purchase? CHENJI provides free engineering tools to size your machine correctly and manage logistics. The UTM capacity selector helps you choose the right testing machine capacity for your material, and the container loading calculator helps you plan how many machines fit in a shipping container. Used together with the industry sections above, they let you specify a machine that matches your specimen and your shipping plan before you request a quotation.
If you would rather ask directly, send us your material, product and test standard and our engineers will recommend the machine, the fixtures and the accessories that fit your application. We help customers from specification through installation, and spare parts, consumables and calibration support remain available after delivery.
Frequently Asked Questions
Which testing machine do I need for metal tensile testing?
For general metal tensile and yield testing an electronic universal testing machine or a hydraulic universal testing machine is used, selected by capacity; for rebar and heavy sections a 1000 kN or 2000 kN hydraulic frame is typical.
How is spring performance tested?
Spring load-deflection and stiffness are measured on an electronic universal testing machine, and spring fatigue life is measured on a resonance fatigue testing machine at 50-250 Hz.
How is melt flow rate of plastics measured?
On a melt flow rate meter such as the CXNR-400D, which determines MFR and MVR to ISO 1133, GB/T 3682 and ASTM D1238.
How is hardness tested?
By Vickers, Brinell, Rockwell or Leeb methods depending on the material and the required scale; CHENJI supplies bench and portable hardness testers for each method.
Can CHENJI help me choose the right machine for my application?
Yes. Our engineers match the machine, its fixtures and its software to your material, specimen and test standard; send us your requirement for a recommendation and quotation.
