Follow the following steps to estimate how many machines and what types of machines you need to make your garment in an assembly line. The primary information you need to calculate number of machines are Read more...
17. Which Machines are needed to make Basic Polo Shirts?
Five types of machines are used in making basic Polo Shirt . Machines are Lock stitch (Single Needle), Over edge (Over lock), Button holing, Button attaching and Flat lock (Flat bed). Read more...
18. Which Machines are needed to make Basic Tee Shirts?
Three types of machines are generally used for making Basic Tee (Crew Neck) in mass production. Machines are Lock stitch (Single Needle), Over edge (Over lock) and Flat lock (Flat bed or Cylinder bed). Read more...
19. How to reduce line setting time?
Engineers and production managers always look for a way to improve factory’s labor productivity. But they look over things that lower labor productivity. Read more...
20. What is on-standard efficiency and off-standard efficiency?
When operators are not working on-standard jobs they are simply not producing any garments or any minutes. That is why to know operator’s actual performance on the on-standard jobs; operator’s efficiency is presented as on-standard efficiency. Read more...
21. How to calculate operator efficiency at work?
In apparel manufacturing, skills and expertise of a sewing operator is being presented in “Efficiency” term. An operator with higher efficiency produces more garments than an operator with lower efficiency in the same time frame. When operators work with higher efficiency, manufacturing cost of the factory goes down. Read more...
22. How to calculate efficiency of a production batch or line?
Like individual operator efficiency, efficiency of a production line or batch or section is important for a factory. Daily line efficiency shows the line performance. To calculate efficiency of a line for a day, you will need following data (information) from the line supervisor or line recorder. Read more...
23. Operation Break-down and SAM of the Full Sleeve Men's Formal Shirt?
Prior to defining SAM of the garment, detailed operation break-down is made by engineer. Both manual and machine operations are included in the operation list. Then a skilled operator is given to do operations one by one. 5 to 10 samples are studied. All operations are studied by GSD expert for motion analysis. Read more...
24. Engineers, Be careful with data what you presenting to your boss
Business owners normally seek for data about the performance of the factory from engineers. The primary KPIs are line efficiency, machine productivity of the current running orders, production capacity production cost etc. Read more...
25. Can anybody hit 100% Efficiency of GSD SAM?
I have intentionally referred ‘GSD SAM’ because most of garment engineers, industry experts and business owners believe that GSD based standard minutes are more accurate than other. You may feel that what a silly question it is. But I met numbers of young industrial engineers, who ask me questions in the same way I have titled this article. Read more...
26. How to Find Actual RPM of the machines running on the floor?
Though sewing machine manufacturers define machine rpm (maximum level) in the machine label and manual, in the floor machines are not being operated at maximum speed by the operator. Sewing operator runs a machine at lower a speed than specified maximum speed limit.
27. What is Pitch Time, Pitch Diagram and how to make a Pitch Diagram?
Pitch time: In industrial Engineering, Pitch time is a ratio of total SAM of garment and number of operations to be set for the style
28. How to grade sewing operators?
Generally workers are categorized as skilled, Semi-skilled and unskilled for deciding wages for them. Others grade operators as A, B or C according their experience and expertise on the job. If grading of the operators is done scientifically it will help in selection of operators during line setting of a new style.
