Tensile tests for plastic film, just like tensile tests in general, measure the force required to break a specimen and the extent to which the specimen stretches or elongates <br /> <br /> <br /> to that breaking point. Tensile tests produce a stress-strain diagram, which is used to determine elastic modulus, ultimate tensile stress, and maximum elongation. The data will be used to specify plastic material for packaging and as a quality control check of plastic materials. In order to perform the above test, a special tensile testing machine is needed. The main objective of this research is to design and manufacture tensile testing machine for plastic film. This research work is the result of cooperation between industry, represented by the PT. Norita Flexindo, a local packaging company located in Cileungsi, <br /> <br /> <br /> Bogor, and The Faculty of Mechanical and Aerospace Engineering (FMAE), Institut Teknologi Bandung (ITB). Due to the complexity of the work, this final project is split <br /> <br /> <br /> into two parts. The first part, which is the design and manufacturing, will be covered in this report, while the testing is performed by another student, Randy Ryantama (student ID number 13105033). <br /> <br /> <br /> The main reference for this research work is the ASTM D882-02. Based on this standard, a conceptual design for the tensile testing machine is formulated. After thorough <br /> <br /> <br /> component selection and analysis, a detailed design is obtained. As a continuation, a prototype is manufactured. The manufacturing process is completed in the workshop of <br /> <br /> <br /> PT. Norita Flexindo. Following the completion of the prototype, a testing procedure is formulated and performed. This portion of the work which includes sensor selection, measurement set up, and data acquisition program writing, is covered in the second part of the research work by Randy Ryantama. Test result concludes that the prototype is functioning properly and may be further developed into a commercial product.
