Abstract
This project are discusses about the development of Easy Metal Stamper Machine Prototype for
Welding and Metal Fabrication Workshop. The goal of this project is to provide a Metal Stamper
Machine that can be used in the teaching and learning process for mechanical workshop practices
courses in the Department of Mechanical Engineering, Politeknik Mukah Sarawak. Main factor for
development of Metal Stamper Machine is generating innovation in the process of identity imprint on
the students' workpiece. The development involves several stages starting with the design of the
machine; fabrication and test run of the machine. To test the functionality of this machine, test run has
been carried out on the machine and observations throughout the test run is recorded and a user
satisfaction survey was conducted. The findings of the test run and the user satisfaction survey
showed that this Easy Metal Machine Stamper project helps users in identity imprint work on the
students work piece. Thus, clearly shows the design and construction of this project has been
successful.

Introduction
Easy Metal Stamper is a product that is designed to enable students who are taking Mechanical
Engineering welding workshop practices to mark their finished welding plate with proper and easy
marking method. The design of this product focuses on the safety of the user and allows better
finishing on the welding plate. With its flexible design, this product uses simple mechanism to be
operated and can be used repeatedly without hassle. In addition, this product uses durable and strong
material such as mild steel and the product itself is made to be long lasting and able to be use
immediately. With the added safety features such as the “START” button, sensor and buzzer, this will
ensure the safety of the students who are using the stamper from injuring themselves. From the
research on mechanism we have made, by using motor, it will leave deeper and much clearer mark
from the letter and number puncher on the metal plate.
Students of Politeknik Mukah Sarawak who are undergoing Diploma in Mechanical
Engineering will be taking the subject Mechanical Workshop Practice on welding activities. From
Semester 1 until Semester 3, students learn the knowledge of various types of welding such as arc
welding, oxy-acetylene welding, tungsten inert gas (TIG) welding and metal inert gas (MIG) welding.
Students are then given a duration of 3 to 4 weeks to learn on how to weld and by the end of the final
week, the students are then ask to do practical task where they applied the knowledge they gain and
will weld any give mild-steel plate (with accordance to the type of welding practices) by their
lecturers. Once done, students are then asked to mark their respective plates by writing down their
names and registration number respectively so that the lecturers in charge are able to give scores on
the work done. The problem arises during the marking of the welding plates by the students once they
are done with their task. The current method that is being used to mark their metal plate is by using
paint marker or some may use a hammer with punchers. By using such methods, we have found out
that there were safety concern arises where students often hurt themselves from accidently touching
the hot surface of the metal plates. Apart from that, the usage of paint marker is not efficient because
most paint marker’s tip ended up ruined because most student will not wait for their metal plate to
cool completely and will simply write down the ir name and ruined the tip of the marker from the heat
of the metal plate. This eventually promotes on material waste as most markers aren’t fully utilized.
Further weaknesses using paint marker is that we also noticed that students could not do proper and
clean finishing on their plates. Normally, the tip of the paint marker provided is big and thus this takes
