Do Our Best for Your Test Drop Weight Impact Testing Machine| Functions This type of machine is especially designed for drop-weight test of pipe and plate (including plastics, ceramic, Nylon, and building materials). Equipped with force measurement system, it fully satisfies instrumented impact tests complying with international standards. ASTM D 7136/D 7136M, ASTM D 7192, ASTM D5628 ASTM D 3763, ASTM E 23, ASTM D2444, ASTM E208 ISO 148, ISO 14556, EN 10045, DIN 50115 Compared with traditional pendulum impact testing machine, instrumented type is more useful for accurate analysis of material property during crack, facilitating the engineers to understand the most fragile part of materials when developing new materials. In addition to providing an measure of total absorbed energy displacement parameters, such as the pre-maximum force energy (Wm); the post maximum force energy; the general yield force (Fgy); the force at brittle fracture initiation (Fbf); the arrest force (Fa). Wance is the leading R&D and manufacturing of instrumented impact testing system in China, and has experienced experts for force transducer design. Combined with our high speed data sampling system, Wance provides the full complement of solutions for laboratory, ranging from 0.1J for engineering plastic to 100,000J for steel DWTT test. 1. Motorized control by computer: setup of drop height and striker mass, automatic lift and release of striker, automatic data acquisition 2. Automatic control: anti-rebound to prevent secondary impact, potion the zero point for different specimen, clamp the striker to preset height, and detect the door open/close. Dedicated control panel and touch screen can satisfy test requirements, real-time display of crosshead height, set up of drop height, mass and other parameters. Optical sensor is to detect impact speed before/after impact. 3. High speed instrumented test system offers high precision transducer, allowing to automatically sampling data and plot force-displacement curve for analysis. Sampling frequency is up to 2MHz, with 6000 points storage capacity on each channel, and dynamic loading measurement error is less than <2%. 4. Pneumatic fixture for plastic plate test Page

Drop Weight Impact Testing Machine| Spring driven device This mechanism provides high speed impact on specimen, depending on high strength spring beside of free drop. Speed detector Speed is measured by optical encoder. By measurement of speed at the instant before impact and after impact, the calculated kinetic energy difference before and after impact is the absorbed energy and friction losses. By correction of friction losses, the exact absorbed energy can be calculated. Anti-rebound device This device is to prevent secondary impact on specimen when tup rebounds after impact. It consists...

Drop Weight Impact Testing Machine| Safety protection shield Fully closed protection shield prevents broken specimen from splitting. Interlock door further improves safety. Control electronics SIMENS programmable PLC is used for automatic control, including striker clamp, lift, zero positioning and impact. Touch screen is used for test interface. Rotary encoder is used for measurement of height. Instrumented system 1) Principal Force transducer in striker transfers the force signal to high speed data conditioner for amplification. Then the signal is A/D converted by high speed sampling...
