Abstract
With the advancements of the times, the emergence of new materials has brought more space for development and imagination to architecture. Unique materials are accompanied by different specialized manufacturing methods and material performance. The rise of digitally assisted manufacturing and design, encourages designers to intervene in CNC tooling and material manipulations during the design process. The development of this trend in customized machine processing allows the designer new design possibilities and greater control through computer simulation and machine collaboration. This thesis paper discusses the manufacturing method of magnetic stretch molding, through the analysis of magnetic materials, the arrangement of magnetic fields and the tool path control of the machine for manufacturing and processing.In regards to the magnetic materials, the magnetic plastic is formed by mixing plastic resin and magnetic powder. Material ratios and mechanical test were conducted to establish a baseline for the performance characteristics and form generation traits of the magnetic plastic during stretch forming, through a magnetic field environment generated by the attraction and repulsion force of high strength magnets. According to the material restrictions obtained by these tests, custom CNC tools were designed and fabricated that could be used to control the coordinate positioning of multiple magnets in space. The magnetic forming is created through the positioning, polarity of the magnet field and the design of multi-point magnetic arrangement patterns.
The primary advantages of this type of magnetic plastic forming process, which can be directly controlled with the magnetic force of a single machine into various shapes, is the reduction in the mold manufacturing components when compared with general plastic material molding methods and in use cases in environments with limited manufacturing facilities.
