CHAPTER 11 : TYPE OF PROCESSES

There are 3 type of processes in modern manufacturing industries :

• Continuous Process
• Batch Process
• Individual Products Production

1. Continuous Process 

Process which raw materials enter one end of the system and the finished product comes out the other end of the system and the process itself runs continuously. Continuous process using long period of time such as minutes, days or month. It's depending on process in manufacturing industry.

2. Batch Process

There is no flow of product material from one section of the process to another. Each batch of product may be different, many chemically company  based products are manufactured by using batch processes. Because as we known a lot of chemical company using a lot of material.

3. Individual Products Process

Process which is the most common of all processing systems, with this manufacturing process, a series of operation produces a useful output product. The item being produces may be required to be bent, drilled, welded, and so on. At different steps in process, the workpiece is normally a discrete part that must be handled on individual basis.

There are 3 type of processes and in modern automated industrial plant, the control of machines of processes can be divided into the following categories :

• Electromechanical Control
• Hardwired electronic control
• Programmable hardwired electronic control
• PLC (Programmable Logic Control)
• Computer Control (NC)
