18. Characteristics of Batch Production
1/7 U.Aravind, Lecturer, Department of Mechanical Engineering, Lakshmi Ammal Polytechnic College., Kovilpatti.
• Products are produced in batches of
small quantities
• Products are highly standardized
• Both Special purpose and general
purpose machines are used
• Semi skilled and skilled workers are
employed
• Material handling is used
• Supervision is not so easy

19. Characteristics of Batch Production
1/7 U.Aravind, Lecturer, Department of Mechanical Engineering, Lakshmi Ammal Polytechnic College., Kovilpatti.
• Preventive as well as routine
maintenance are followed
• Product layout and process layout
combination is used
• Machine breakdown is not so serious,
because work can be shifted to another
machine
• Flow of material is intermittent
• Unit cost is more
• Production is started only after the
receipt of sufficient supply orders.
