Abstract

Vacuum forming machine is a machine that performs vacuum forming process in which a plastic sheet is heated to suitable temperature,stretched around into a mould and then comformed to the mould by creating vacuum pressure between the plastic sheet and surface of mould.There are many products manufactured by vacuum forming process.They are becoming increasing popular because of the low cost and convenient modification.However,the vacuum forming machine in the marketplace is expensive and large.This would be extremely unwise to buy an expensive vacuum forming machine just for personal use or the small amount of usage.Therefore,in this project,a simple and low cost vacuum forming machine was designed and developed for learning purpose.At first,the dominant requirements were determined,that is low manufacturing and maintenance cost,easy to operate,safe and etcetera.In this project four design concept of vacuum forming machines were designed with the methods such as brainstorming.objective tree.morphological chart and etc.The Pugh method was used to select the best design concept.All designs were evaluated based on product design specifications that are performance.appearance and economy.Finally,Design concept 4 was selected due to its outstanding features compared to others.Then,Design concept 4 was drawn in detail by Software CATIA V5R20.Product analysis were carried out in order to calculate and determine the required amount of power supply to heat the plastic sheet until it is soften.The results have known that 1.5mm thickness of ABS plastic sheet can be soften and formed after being heated at around 44 W in 3 min.After that,a prototype was fabricated and tested.The estimated price for the prototype of vacuum forming machine is about RM 108.89.
