Aluminium alloys was used in the automotive parts industry increased for compensate steel parts material due to its lightweight and good surface. Since aluminium alloys are there relatively low mechanical properties although they can be deformed easily but the major limitation is their low formability. Especially the less bending radius which is often bending surface damaged easily. In the present work five-difference ratio of sheet thickness and bending radius for study to the bendability of cold rolled aluminum alloys AA6016 at low bending radius. The bending test by Air-bending method according to ISO 7438: 2010. To compare the results every 15 degrees. The mechanical behaviour surface roughness microstructure and damage evolution in the fillet region were analysed by experimental research. The experiment clearly showed that the Spring-back angle and bendability tend to decrease as the bending angle and material thickness increase. Due to the high tensile stress on the bending surface it effected to the surface roughness increases rapidly and led to the damage on the specimen bending surface. The initial cracks occur on the middle of the outer surface curvature and propagation in the shear plane pattern to the middle of the sheet thickness along the grain boundary. This is the consequence of plastic deformation by bending test.

The plastic outlet problem is a rigid inflexible material. When assembling with a metal outlet set then it is usually not completely homogeneous. When used The outlet burns out quite often. And the plastic itself is less heat resistant. This allows the plastic to melt burn easily and conform to the upgrade of technology capabilities in precision mold manufacturing. And high complexity The researcher has foreseen the factors in making Developing the design and manufacturing of rubber plug molds economic opportunities for Natural Rubber Applications Therefore came up with the idea to develop the design and material selection. And the factors that affect the production is the mold and the process of forming. To help entrepreneurs to exchange knowledge and study the knowledge from this research to continue in the application of natural rubber to increase future value. From the results and experiments it was found that the study of the method of creating a prototype compression molding kit by using rubber forming techniques can be applied and used by various components of forming rubber can be used to develop forming Rubber plug sockets are possible and this process can produce prototypes from natural rubber.

The objective of this research was to develop the engineering students in accordance with the Bachelor of Engineering (B.Eng.) curriculum (industrial engineering) through the work-integrated learning program under which the students worked in the production line from Monday to Friday and studied the theories on Saturday. The learning program continued throughout the semester under the collaboration with Thai Cutting Tools Manufacturers (TCTM) of which 26 companies participated in the program. The program determined the development plan for the students of IE.102 course: Basic Production Process for Engineers through the project-based learning (PBL) program in accordance with the CDIO standard (Standards No.1-4). Twenty-seven (27) students of the work-integrated learning (WiL) program worked in 7 companies which were manufacturers and developers of cutting tools machine tools high precision parts and machines. All participating companies were designer and developers of new products and innovations and their products were distributed in and outside the country. Hence the students learnt from working in the production line to create new products according to the production plan. The products newly created through the integrated production method consisted of machine tools automated machines lathe milling drilling fitting grinding welding and metal sheets. The students learnt to use the tools to assemble and create the machines and developed the technology operation skill for production of high precision products. The learning and working were combined and applied to create those products. The students’ skills were developed in compliance with the CDIO standard (Standards No. 5) as the program required them to work in the workspaces to create the products in compliance with the CDIO standard (Standards No.6). The students created the cutting tools in compliance with the CDIO standard (Standard No.7) such as drills center drills end mills reamers insert tools and cutter tools. The students also created shafts gears bushes bolts and wedge assembled the parts in the power transmission of the machines the electric and electronic circuits of the machines and the electric motors and created the machines and molds for production. The teaching arrangement learning assessment and examination of the students’ competency were assessed from the integrated learning skills. Each student undertook the practices to develop the personal and interpersonal skills. The program development was based on self-learning under the supervision monitoring and recommendation of the lecturers specialized in the product design product creation and production management to develop the students in compliance with the CDIO standard (Standard No.7).The students practiced different skills such as conceiving designing implementing and operating respectively.
