Abstract

This project is conducted to study about the design and machining process of fabricating core and cavity plate for two-plate family mould. The main purpose of this project is to improve the current mould by redesigned and fabricated the twoplate family mould that contain four testing specimens of tensile, flexural, impact, and hardness test. The main machining method to fabricate this mould is through CNC milling machine where the machine model that used are Hass VF-1 allocated in UTeM. The mould design is created with AutoCAD software where the 2-dimensional (2D) diagram visual is produced. It is then converted into 3-dimensional (3D) by using EdgeCAM and the G-Code for the CNC Milling machine is generated together with the drawing. The machining process started with the machining of ejector holes, the profiles, and finally the runner where the machining began with the core plate, cavity, backup and end at ejector plate. The mould was then assembled and a trial test run was conducted whether the mould produced the test product and it’s a success on first trial with the same parameter for the old mould. Thus, it can be concluded that by improving the parameter of the injection moulding for the new mould, the quality of the product can be improved and defects can be minimized.
