In the manufacturing process, DFM establishes design functions with more knowledge of manufacturing operations. The most effective method is manufacture which represents a part of the overall process and design development (Pueo et al., 2019). Manufacturing design principles can help designers to reduce the costs and difficulties of manufacturing a product, i.e., reduce the total number of parts of the product, develop modular designs, and use standard components. Design parts is planned to be multi-functional and multipurpose component designs which are easy to make, capable to avoid locking devices apart, possible to minimize assembly direction while maximize execution and minimize lifting (Grudzień et al.,2016). Manufacturing process is defined as a method or process that is applied to change the shape of an object. According to the economic side, the understanding of the manufacture process is a value-added activity, where the conversion of materials into products adds value to the original material (Bikas et al., 2016). As part of the manufacture, machining process is also a vital, which is conducted to produce an assembled parts using machine tools, which utilizes the relative motion between the chisel with the work-piece. The machining process is continued by the formation process which is the production process conducted by giving a load to the material until plastic deformation occurs so that the product is formed according to the desired shape and size. After that, the connecting stage is performed which is intended to combine two or more materials to get the desired product. The joining process follows the process which is conducted in the forms of welding, brazing, soldering, drying, gluing with glue, and connecting with bolts. The heat treatment process can be considered if material needs changes in its properties. This process is usually performed by a thermal treatment to metallic materials (Kim et al., 2016; Fang al., 2018). 3. Results and discussion 3.1. Fundamental profile on the heating coil 2D drawings are created and cannot be duplicated by outsiders in the form of CAD. Image produced from request based on existing library design. Several 2D models of sulfur melter heating coil (all units in mm) are presented in Figures 2 to 4.
