This study developed crash box design on origami patterns. These typically have got the dents whichserve as pre-folding. Therefore, the collapses modesarepredictable and stable. The geometry variation of crash box comprises four factors, i.e. basin length (c), distance between the basins (b), thickness (t) and number of segments (M). Meanwhile, the design of optimal variations utilized L9 Taguchi and deformas pattern analysis. The method of this study used software finite and the element of crash box modelling consists of three components, e.g. impactor, crashbox, and fixed support. The material used is AA7003-T7 modellingas thebilinear isotropic hardening. Model loading waconveyed 64 km/h on the impactor. The research shows that the response of quality characteristics of energy absorption is the larger the better. The energy absorption respectively covered 1)thickness (t), 2) segment (M), 3) distance between basins (b), and 4) basin length (c).Whereas, the highest energy absorption of the crash box occupied by the origami pattern no. 3 with c = 9 mm, b = 60 mm, t = 2 mm and M = 6, Â reaching 7,247,826 J.

Crash box serves as a kinetic energy absorber during collision. It has a tube shape, which is located between bumper and chasis. The crash box design requires development in order to reduce buckling mode and obtain symmetry folding mechanism, so it will achieve greater energy absortion. The researchers find a method to reduce tension due to impact by providing dents in crash box geometry. This research observed origami pattern crash box design having dents functioned as pre-folded so that collapse mode can be predicted and stable. In this research, the crash box was modeled according to the size of bumper and chassis on the MPV car. Testing simulation was performed by modelling Impactor as rigid body and crash box as flexible. Fixed support was housted in the surface of rear side of the crash box. Simulation process was started from the impactor moving to supress crash box. This Impactor collision led to deformation on the crash box. Crash box material was AA7004-T7, it was modelled as bilinier isotropic hardening. Based on the research result, the addition of pre folded pattern is able to reduce impact force at the first impact and has stable characteristic as well as predictable collapse mode.

Crash Box attached between bumper and chassis of a car serving as a kinetic energy absorber during the collision. In previous research, origami pattern crash box was tested at low speed, high speed, and frontal impact and oblique impact directions. They resulted predictable collapse and stable deformation patterns. It is directly proportional to the energy absorption during the impact. Origami pattern crash box was modeled in square but it cannot be used if it is applied in MPV car, the geometry is unsuitable to the bumper and chassis. Therefore, in this research, the crash box designed according to the size of bumper and chassis of MPV car where its shape is rectangular on the surface. This research will compare the deformation pattern between origami and rectangular crash box adapted to conditions and dimensions of the MPV car. Design built using CAD software and simulation is performed using FEM (Finite Element Method) software. Simulation test modeled with impactor, bumper and crash box, while offset frontal test with 16 km/h impact speed conducted using material bilinear isotropic hardening modeling. Result show that origami pattern crash box has predictable deformation pattern than rectangular pattern crash box.

In the car, the body structure is designed in such a way so as to transfer and absorb energy. This serves to minimize the result of this accident related to kinetic energy. This needs a system to absorb the kinetic energy maximally, so as a result of a frontal collision events that can be reduced optimally and kinetic energy can be absorbed by a front body structure. Devices used for absorbing kinetic energy in the car is usually called a crash box, which is located between the main structure and bumper. Crash Box generally tubular thin shaped. It has been a lot of research about the crash box. In this study using crash box origami patterns and using methods taguchi orthogonal array L9 (34). AA7003-T7 aluminum material modeled as bilinear isotropic hardening, the loading method is Frontal Impact Frontal Angular Position with impact angles of 5, 15 and 30 degree by using the finite element software simulation methods.

Metal casting with investment casting method is metal casting which has the ability to produce accurate parts and has a controlled fineness. Current technological developments are very influential in the development of investment casting. One of them has been found mold-lay filament as a substitute for wax, which is now wax is one of the main components in investment casting process. Mold-lay filament is printed using a 3D Printer machine. In this study, the wax in the investment casting process was replaced by a mold-lay filament with the specifications 0.75kg / 0.55 lb of 1.75mm MOLDLAY filament, prints at temperatures of 170-180° C. The result show that mold-lay flutes are also able to come out well from slurry molds, but require more time than wax, this is because one of the plastic mold-lay compositions, which takes a long time for the moldlay fillment to come out of the mold. Further research suggestions are needed further testing in terms of roughness of the product with moldlay filament and compared with wax. This will also see if there are any remaining moldlay filaments from the mold.
