It is a batch-type film biaxial stretching device. It can experimentally evaluate and determine the processing suitability conditions and product value of the stretched film.
The demand for high value-added plastic films has been increasing in recent years, leading to a need for further improvements in the accuracy and functionality of testing machines. This biaxial stretching testing device employs a servo-driven system to enhance stretching speed and diversify stretching modes, allowing for tests under various conditions for biaxial stretched films, thus obtaining appropriate processing conditions for samples. - The stretching method adopts a center stretch type, and the drive system uses a servo motor, enabling high-precision stretching to produce uniform films. - Various stretching processes can be performed by setting stretching programs for different conditions. - Sample attachment can be done safely and quickly using a gas pressure grip. - Customization is possible to meet customer needs, including stretching ratios, load detection, secondary heating devices, and data processing. ● Sample testing is available at our factory in Itabashi, Tokyo, so please feel free to contact us.
