No. 643 Drop Weight Impact Testing Machine This is an instrumented impact testing machine that simultaneously measures the force and displacement of impact failure, allowing for the evaluation of the impact failure characteristics of plate-like materials such as plastics by measuring maximum impact force, displacement at maximum impact force, energy at maximum impact force, and puncture energy. 【Features】 (1) By changing test conditions such as the weight of the drop weight and the height of the drop, free fall tests can be conducted to detect impact force, displacement, and duration of action. (2) The impact velocity of free fall can be adjusted in the range of 1.40 to 5.05 m/s depending on the height of the drop weight. (3) The control unit can be connected to a PC to send test results to a spreadsheet software worksheet. (4) Test conditions can be input and test results can be checked on the touch panel of the control unit. (5) By equipping an acceleration device using springs (optional), impact tests can be conducted at higher speeds (1.40 to 16.00 m/s) than free fall. (6) When a sample holding device (optional) is installed, it can automatically press the sample when the door is closed, allowing tests to be conducted with the sample fixed in place.

The "Strograph" is a versatile testing machine that conducts characteristic evaluation tests for tensile, compression, and bending strength of various materials such as plastic and rubber. It can measure the mechanical properties of test specimens, including "tensile strength, elongation, yield point, endurance limit, stress, bending load, bending strength, and bending modulus." 【What is a Tensile Test?】 The purpose of a tensile test is to understand the characteristics in relation to tensile force. This test applies tension to the sample until it fractures, measuring the mechanical properties such as tensile strength, yield point, and elongation. From these measurements, the fracture state and yield state are calculated and used for material strength calculations. 【What is a Compression Test?】 A compression test involves placing test specimens, such as rectangular prisms, cylinders, or cylindrical shapes, between two parallel plates and applying a load to determine the relationship between stress and strain until failure occurs. 【Specifications of the Strograph】 You can choose from models with a capacity ranging from 500N to 50kN. Additionally, we offer a variety of grips (chucks) depending on the samples being measured. If standard products do not meet your needs, custom solutions are also available, so please feel free to consult with us. We have demo units available at our factory, so if you wish to measure samples, please do not hesitate to contact us.

The "Laboplastomill" is a testing device used for evaluating processing characteristics and simulating molding using small mixers and extruders. It is widely utilized by many customers in the field of polymer materials, including thermoplastic resins, thermosetting resins, and elastomers. There are various methods for testing, but it allows measurements to be conducted under conditions close to those of actual production molding processes, enabling the acquisition of practical measurement data from a small amount of samples. For more details, please refer to the attached materials. Additionally, we have a demonstration unit at our factory, so please feel free to contact us if you wish to conduct sample testing.
