Operation Breakdown of Swim Short

This swim short is easy to prepare the layout. You may face problem to attach sticker which is surrounded the zipper. In my industrial engineering tutorial series, I am sharing an operation breakdown of Swim Short. You can refer to this operation bulletin to learn about various operations involved and machine requirements in making swim short or swim trunk. I describe the operation breakdown of Swim Short (Full Elastic Waistband). It is also known as swim trunk.

Operation Breakdown of Swim Short

Operation Breakdown of Swim Short is done by the following table. It is also known as an operation bulletin of swim short. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 70% efficiency are shown. The estimated time (SMV) shown in the below table will vary according to the product method followed and machine and equipment used in actual production. So please be careful while you use the above estimated time against each operation.

Operation Breakdown makes our work easy to set up a production line. We easily manage machine and operator requirements for any sewing line by this. But it is necessary to do an operation breakdown of swim short to prepare a machine layout. You can read my previous post on Operation Bulletin of boys Swimwear.
