Abstract

The unknown fatigue life of injection molded plastic materials and the ineffectiveness of clamping both ends of the specimen in the collet of the Integrated Rotary Bending Fatigue Testing Machine with manual tightening and loosening are the obstacles faced. The purpose of testing and making a collet nut driver is to obtain a prediction of the fatigue life of injection molded plastic materials and to increase the effectiveness of clamping the end of the specimen with the help of a DC motor drive. The research method uses experiments which include injection molding of plastic materials of the type Polypropylene (PP) and Acrylonitrile Butadiene Styrene (ABS), checking the straightness and surface finishing of the specimen, fatigue testing at 1800, 2000, 2200 rpm, analysis of fatigue test results, and design-manufacturing collet nut drive with DC motor drive and transmission of a pair of spiral cone gears, manufacture of DC motor sliding movement mechanism along the reach of both ends of the specimen, installation of electric power circuits for direction and electric current switches for clockwise and counterclockwise rotation functions, and analysis of the results of the fatigue test and performance of the collet nut driver The results of fatigue testing at a bending stress (S) of 68 MPa for PP material show that at 1800 rpm, the fatigue life (N) was obtained at 2,014,605 cycles and at 2200 rpm, N was obtained at 1,506,486 cycles. Meanwhile, for ABS specimens, at 1800 rpm, N was obtained at 1,547,106 cycles and at 2200 rpm, N was obtained at 1,190,425 cycles, which means PP material has a longer fatigue life compared to ABS. The test results of the DC motor drive on the collet nut showed that the duration of tightening/loosening was 4.4 times faster than manually, which originally had a duration of 66 seconds, down to just 15 seconds for the DC motor drive.

Abstract

Manual work using drilling machines, manual grinding, and filing in penetrating holes in the profile of the hollow Aluminum frame in the shape of the glass door lock housing is the problem faced. Community service aims to obtain a portable door lock children's home hole prototype for hollow aluminum frame profiles for glass doors. The method applied is design discussions with partners, making a hole punch frame for a portable door lock housing for an Aluminum frame profile according to the dimensions of a 3 Ton jack, making a punch in the exact shape of a particular key housing hole with an electric discharge machine (EDM) Wire Cut, hardening and tempering steel punch, making sharp side profiles for the shape of the key housing using a CNC milling machine, trial of punching the door frame profile, and handing over the portable door lock home punch tool kit to the service partner. With the completion of the manufacture of the portable door lock children's home punch tool kit as a work aid, it can be used to support the production of glass door frames ordered by the wider community with good results, a fast process, and production costs can be reduced. In this way, there is a synergy between State Polytechnic of Malang (Polinema) and community members in the production of products needed by the community more efficiently and able to meet the needs of the general community.

Abstract

The problem lies in the inconsistency of the dimensions of the 90° S-shaped clothes hanger forming device for use in research requiring bending and deflection forces using the Tarno Grocki compression testing machine. This community service project aims to develop a 90° S-shaped clothes hanger forming device whose design can be used in research requiring bending and deflection forces using the Tarno Grocki compression testing machine and cannot be used as a stand-alone device without the aid of a hydraulic jack and frame as a production tool in a home industry. The method applied is modifying the design and device so that it can function using the Tarno Grocki compression testing machine and a stand-alone device with the aid of a hydraulic jack as a production tool in a home industry, including the construction of a support table, a trial run, and the donation to partners or home industries. The results of the community service in modifying the 90o S-Shaped Clothes Hanger Forming Device can be used as a production tool by the household industry, so that there is a synergy between State Polytechnic of Malang and the community in producing clothes hangers for the community's needs more efficiently and can meet the needs of the community in general.
