Suitable for the preparation of self-hardened resin sand compressive and tensile standard samples.

Used to measure the particle size distribution of the molding material. Its structure consists of motor, body, control box, swing seat, etc.

It is used to measure the gas generation amount and gas generation speed of various types (core) sands, coatings and other molding materials, and can measure the effective amount of coal powder in molded sand.

It is used for direct measurement of the breathability of cast molds in the casting workshop, and also for the breathability of standard samples in the dry or wet state of raw sand for casting and mixture. Digital display and automatic printing functions (with computer communication interface including software).

Used to measure the compressive resistance, shear resistance, bending resistance, tensile strength of molded (core) sand at room temperature. Automatic mechanical loading is adopted, sensors collect data, digital tables display test results directly, and can maintain the maximum destructive force value. It has data storage and output printing functions. The touch screen displayer, equipped with a USB port, and data processing generates .txt files (text format files).

The test machine uses a high-precision stepper motor as the power source. The microcomputer displays the test data and test status in real time. The control of the test process is achieved through the automatic control of the microcomputer. This machine can conduct mechanical properties testing and analysis research on various metals, non-metals and composite materials, and is widely used in aerospace, petrochemicals, mechanical manufacturing, wires, cables, textiles, fibers, plastics, rubber, ceramics, food, pharmaceutical packaging, aluminum-plastic pipes, plastic doors and windows, geotextiles, films, wood, paper, metal materials and manufacturing industries, and can calculate the maximum test force value automatically, break force value and other test data.

The WAW-300D microcomputer control hydraulic universal testing machine uses manual and electro-hydraulic servo dual control mode control technology, computer data acquisition and processing, and can realize closed-loop control and automatic detection high-precision material testing equipment. The under-mounted main engine of the oil cylinder (gap sealing oil cylinder) is mainly used for tensile, compression, bending and shear tests of metal and non-metals. Suitable for metallurgy, construction, light industry, aviation, aerospace, materials, colleges and universities, scientific research institutions and other fields. The test operation and data processing meet the requirements of GB228-2010 "Room Temperature Materials Metal Tensile Test Method".
