What is the single piece of flow in garment production?

Single-piece flow is also called unit synchronous flow, single-piece flow is the comprehensive and effective use of personnel, equipment, logistics, organized, planned, and targeted progress of each unit to balance production. In the production activities, the production batch is a batch, there is no stagnation between the front and rear processes, and each process is completed with self-inspection and a process, and the production mode of transmitting a process is called a flow of production mode, referred to as a single piece flow.

Characteristics of a single piece of flow:

1. Target management: production capacity targeting, and industrial engineers set the target capacity of each unit (process) of the product; 2. Time management: time quantification, and the industrial engineer sets the target operation time for each unit (process) of the product;

3. Fast production of finished products, rapid response to quality problems, and zero batch quality accidents;

4. Forward and backward pull type: it is different from the traditional production mode, the traditional production mode, the production line is passive, and can only wait for the materials, cutting, embroidery, and printing of the front department to determine the normal operation of production, while the single-piece flow production is in the initiative, and the front process must meet the production line, all for the sake of production. Forward push, not only on the flow of forward, it includes orders, materials, product reprocessing.

The post-pull is to meet the needs of customers and pull the whole production and the first chain.

A single piece of flow is a production line, starting from the line, each person does a process, to the last person, a piece of clothing is ready. Such an assembly line is very efficient, and there is no need to move around. When this process is done, it will automatically move on to the next process.

According to the usual practice in the past, it takes 2 to 3 days from the time the clothes are made online to the time when they see the finished product.

But according to the flow of a single piece, the finished product can be seen on the same day.

The production of the garment industry has been in a traditional way for many years, and it is more common to use the "baling" operation. The basic situation of this method is that the sewing process of a product is broken down into several processes, each of which is made by one or a group of workers. In each process from the front to the back, each person sews multiple products in a concentrated manner, and then passes the processing one by one in a "packing" method to complete the entire product.

The form of "single piece flow" is to subdivide the production process of a garment into multiple processes, arrange according to the pre-prepared "man-machine station layout drawing", and complete the "single piece flow operation" from front to back. Each operation unit post completes a relatively single production content according to the requirements of the "personal kanban" (work instruction), forming a continuous operation form of "one process after another, one product after another".

The garment assembly line generally adopts automatic hanging system or manual transmission or mechanical conveyor belt, which generally has the following characteristics:

Single-piece flow synchronicity.

Balance the basic requirements of organizing the production process of the garment assembly line.

Continuity: refers to the continuous flow of products between various processes, closely connected in the world, and always in a state of motion.

Proportionality: refers to the appropriate proportional relationship between the stages of the production process and the production capacity.

Parallelism: refers to the fact that the various production activities of the production process are carried out in parallel as much as possible in time.

Rhythmic: It refers to the production of the same number of products in the same amount of time in each production link, and the load of each working place is relatively stable, so that there will be no loose and tight, loose before and then tight, or tight before and then loose.
