Factory layout design is a way of installing equipment and means of production in a reasonable sewing line or workshop for good production, high productivity and labor safety. In the layout plan of the garment factory, conventional symbols are used to draw and note equipment symbols, occupancy dimensions, and aisle void sizes.
+ The shortest path to semi-finished products, for the fastest product delivery time
+ Takes up less space to save machines and workers
The person who designed the layout of the garment factory clearly understands the size and structure of the factory. The premises are based on technology regulations, the working positions are arranged reasonably, ensuring production organization
The garment factory must be large, airy, full of photos to the convenient transportation route
The production sites are not too far apart. Layout plan of the sewing factory, adding tables for semi-finished products, tables for products, inspection tables ..
Each position is marked and numbered according to the order of the sewing process. There is a notation with the symbol at the bottom of the original drawing with the number of machines and workers.
Layout plan of the sewing factory to design the area for the machine to reserve when changing the new product code
From the drawing of the layout diagram of the garment factory, it is necessary to check carefully before installing equipment and machinery.
Conditions for considering ground layout
Number of workers and employees (male and female)
Machines (size, quantity, weight)
Doors, doors (size, width, position, quantity)
Executive and management office (location)
Warehouse (location, area)
Area of each production location: 4.96 - 6.6 m2
Toilets, changing rooms, canteens, places to store bags…
Canteen: 1 m2/CN .
Changing room: 0.56 m2/CN .
Men's restroom: 1 house for 30 Sun (or less).
Women's restroom: 1 house for 20 Sun (or less)
Calculation of the area of 1 sewing position Type 1:
Calculate position length Dvt.
Dvt = Rm + Rg + k1 + Rt (mm, m)
Dvt = 700 + 350 + 200 + 350 = 1600
Calculate position width Rvt
Rvt = Rm (mm, m )
Rvt = 1200 mm
Calculate the area of the location Svt
Svt = Dvt . Rvt (mm2 ,m2)
Svt = 1.6 . 1.2 = 1.92 m2
Calculation of the area of 1 sewing position Type 2:
Calculate position length Dvt
Dvt = Rm + Rb1 + Rb2 (mm, m)
Dvt = 700 + 600 + 600 = 1900 mm
Calculate position width Rvt
Rvt = Rm + Rb2 + Rb3 (mm, m )
Rvt = 1200 + 300 + 300 = 1800 mm
Calculate the area of the location Svt
Svt = Dvt . Rvt (mm2 ,m2)
Svt = 1.9 . 1.8 = 3.42 m2
Calculation of sewing line area
Calculate the transmission length Dc (mm, m)
Dc = xvtd .Dvt + (xvtd-1) kd + 2.Rb + 2.kb
= (5 . 1.6) + (4 0.6) + (2 .1.5) + (2 .1.5)
= 16.4 m
Calculate the pass width Rc(mm,m)
Rc = xvtn..Rvt + (xvtn -1) kn
= (5 . 1,2) + (4 . 0.6)
= 8.4 m
Calculate the pass area Sc
Sc = Dc . . Rc ( m 2 )
= 16.4 . 8.4
= 137.76 m2
Calculating the area of the garment factory
– Calculate the length of the workshop Dxm (mm, m)
Dxm= xcd .Dc + ( xcd -1 ) k1 + 2 .k2
= (2 . 16.4) + (1 . 2.5) + (2 .1.5)
= 38.3 m
-Calculate the workshop width Rxm(mm,m)
Rxm= xcn .Rc+ ( xcn-1 ) k3+ 2 .k4
= (2 . 8.4) + (1 . 2.5) + (2 . 1.5)
= 22.3 m
Calculate the area of the garment factory Sxm ( m 2 )
Sxm= Dxm . . Rxm ( m 2 )
= 38.3 . 22.3
= 854.09 m2
Production positions, aisles, and gaps are drawn in the same scale (1/50, 1/100 )
Arrange production locations on existing premises or new premises → floor plan
Draw more doors, columns, management positions, toilets, stairs....
Draw more moving arrows for semi-finished products, note the names of the positions (or symbols), the size of the positions, etc.
Determine the length and width of the floor plan
Construction structure in the layout plan of the garment factory
Single-storey houses are the best, multi-storey houses reduce the required area but take up more space for stairs, elevators, corridors, and columns.
High ceiling: 3.5 – 5.5 m
House columns: large and small depending on the number of floors…
Stairs: 2 or more for multi-storey buildings
Floor: flat and bear the weight of machinery
Light: the widest window in the style of 2-3 floors
Path: the straighter the better
Illumination level: ironing intensity 200 lux, cutting 300 lux, sewing 200 - 1000 lux, testing 2000 lux. 1 tube lamp 40 w illuminating 3.3 m2
Ventilation: by air conditioners or blowers, exhaust fans
Important Note
In our country, the design of the premises of the sewing factory and sewing line is often ignored, but often keeps the installation of equipment from the beginning. The movement of goods carried by workers from one location to another, the installation of equipment out of order in the process, does not affect the production line much In advanced countries, the transportation is automated By conveyor, the installation of equipment needs to follow the process, especially the vertical line
