Advance technology and society living were changed in a modern lifestyle, because of global competition that growing so fast they were in need of something that more simple and easy in way to provide their life support. Plastic is the material of which are very suitable and able to meet the demand, currently no less than 250,000 types of product mainly plastic based. To produce goods made from plastic we needed plastic mould. One of the stages of mould manufacturing process is the spotting process, the test match between the cavity and core with the current partingline field meet. Polman Negeri Bandung which is the first polytechnic in Indonesia which has prodi Tool Making and is an expert contributor to the manufacture of mold, until now in the Tool Making laboratory still has no mold spotting machine needed. This research was conducted to find a solution for the mold maker to mould spotting can easily, quickly and the results are good. Before the machine created in the initial stages will be creating the design first, process of design early machine use method of VDI 2222, here in after to get better design and have materials efficiency and proces, so to get design improvement with applying of method of DFMA. The result obtained from this research is the design of horizontal mould spotting machine (HMSM) 300 kN, that meets the Polman needs and using the method of DFMA (design for manufacture and assembly) by Boothroyd and Dewhurst, the design becomes more efficient by design improvement on average 91 % and the cost of materials and process efficiency by 20.23 % from early design.
