Design Razor Blade Assembly Machine

Jack was tasked to re-design and project-manage the manufacture of a £370,000 razor blade assembly machine for a new product range. Before starting the new designs, Jack worked with the assembly team to build trial rigs to validate the manufacturing process and understand the key conditions for it to work. Alongside this, he worked hard to continually develop his knowledge of tolerances, material selection and cost-effective design so that the machinery would function correctly. 

Jack was pro-active in his approach to tasks and, in order to progress his knowledge of good machine building practice, participated in design reviews with senior engineers, presenting his designs and using feedback to improve the functionality.


Jack ensured that the machine order achieved its assembly completion date. One of the unique mechanisms he designed solved an assembly problem in a way that is faster and more consistent than existing methods. In addition, the mechanism that assembles the blade cartridge to the handle used 70% fewer parts than previous and requires half the man hours to assemble. 

“The machinery that Jack has designed has been assembled and commissioned quickly and effectively. It was clear from an early stage that he has the potential to develop into a very capable design engineer; he has a positive attitude and has achieved all of the targets set. His progress has been rapid and he is seen by his peers as a competent, reliable and hardworking designer. I consider that he is well above the standard that would normally be expected at this stage in his career. We hope that Jack will join Orwin permanently on completion of his degree. Overall, he has made a signifi cant contribution to the success of the projects that he has worked on and has become a valued member of the design team.”
