3 The research of this study involved the application of reverse engineering in
producing plastic keris mould for plastic injection molding. The main focus of this study is the methodology and the application of reverse engineering in a real
situation of product development. The process will follow normal reverse engineering steps and procedure and also will look on ways to produce a new
product by taking an existing part as a reference. In this study, the main property to be identified is a design process on how to produce the plastic keris. By taking the
product properties it will then identify the manufacturing process involved in plastic injection mold making. Therefore, the reverse engineering application is find out
how to produce the plastic keris by redesign the core and the cavity of the Dogbone Mould.
1.2 Importance and Benefits of Research
Most of the organization facilities are theoretically claimed to have the facilities to follow in the development of mold making. Reverse engineering are known as an
important element in product development. By combining reverse engineering and mold making techniques the facilities can be utilize and tested on its capabilities of
producing mold by applying a combination of CAD capabilities, measurements tools and other resources possible.
The purpose of this study is to develop and redesign a core and the cavity for a plastic keris and to analyze the manufacturing process and its requirement of the
product or part being study. Using an existing Dogbone core and cavity as a benchmark to produce another core and cavity for the plastics keris. Most of the
purpose is to know the reverse engineering application in producing the parts of the mold for injection molding.
4 The reverse engineering application in some of the industry needs a high cost in
term of machining and its equipments. It is also a barrier for the industry to redesign an existing product as their own manufacturing product. The product existed needs
a reverse engineering process to find the actual process of design and the manufacturing process implemented on it. Therefore, by taking reverse engineering
as a method to get close the manufacturing of the product, the cost of the product can be reduced. For this case the re-designed process is only the core and cavity of
the Dogbone Mould. If the process is verified accurate then the mold can be manufactured and they can produce without depending on other organizations to
fabricate or to purchase a mold.
Nowadays, with the knowledge in engineering field some of the components and part can be re-engineered to improve and developed their usage in manufacturing
process. There are many advantages of using reverse engineering especially for a product of injection molding: Bradley, 1998.
