FABRICATION OF VACUUM FORMING MACHINE

Abstract

Vacuum forming machines are widely used in the advertising industry for making 3D signage, packaging industry for packing different components such as plastic casing for headphones etc. and orthotics parts in the medical field. The machine is available worldwide but is very expensive. This thesis aimed to develop a cost-effective Vacuum Forming Machine that can form ABS, HIPS, and acrylic material in a vacuum forming process. The design was achieved through reverse engineering and integration of high vacuum system, smart sensors, and a simple user interface. The machine can form complex 3D parts with high accuracy and consistency. Production of the machine involved outsourcing part and sub-assemblies to various mechanical fabrication shops. The development of this machine strengthens the industry-university linkages and fosters cooperation. This locally developed machine has potential for export and can be repaired in Pakistan, creating jobs and improving the quality of formed parts.
