This project report discusses the production of 5 liter gasoline jerry cans using blow moulding. It describes a JHB EBMC blow moulding machine that can produce 356 bottles per hour. The machine uses electric and pneumatic parts with servomotors for high positioning accuracy. It has mechanisms to reduce defective products like parting line misalignment prevention. The process involves reheating preforms in an oven, blow moulding using air pressure to form the container, then removing excess material before placing the finished product on a conveyor belt.

- 1. EE 5001 Project Report Gasoline Container Blow Moulder Group: - Kaustubh.A.Deshpande, Prathmesh.R.Kumbhare Introduction This project involves the production of 5 liter jerry cans which are generally used for storing gasoline by using the blow moulding technique. We referred to the video link below:- https://www.youtube.com/watch?v=7Ktr24o5Vzg The video shows the working of the JHB EBMC machines which are used for stable moulding of high quality products. The machine uses only electric and pneumatic parts and thanks to installing a servomotor for motion, we ensure high positioning accuracy and stabilization of motion speed. High quality is maintained by the machine by using unique mechanisms such as parting line misalignment prevention mechanism which reduces the defective product rate, automatic adjustment of the mouth cutting positions when moulding multiple parisons, and calibrating force equalizing mechanism which eliminates the time for adjustment calibrator’s height and reduces the time spent for changing moulds. This machine is efficient and can produce 356 bottles per hour.
- 2. The image shows the various mechanism present in the machine. The blow moulding mechanism and the clamping mechanism are servo controlled. The clamping mechanism has 3 axes of operation while the blow moulding has one. The conveyor belt is non-servo controlled and is just started and stopped. Process The preforms which are previously injected are again passed through an oven to be reheated. The preforms are then picked up by the blow moulding mechanism. Once inside the mould, a pusher and high air pressure blows the container and the mould then opens to eject the container. The newly formed container is then held in position so that unnecessary parts formed during the moulding process can be removed. The finished product is then picked up by a clamping mechanism and put on the conveyor belt for further transport. The general overview of the blow moulding process is as shown in the figure below.
