The aim of using this machinery is to reduce handling time produce quality products in less time.




Common Machines Used for Garment Manufacturing

Cutting Machine


An effective cutting room with good cutting machines is the best foundation in any production unit. The major operation is the cutting room is to cut the spread out fabric. This is the most decisive function - because once the fabric has been cut, very little can be done to correct serious mistakes.

Relatively speaking, fusible interlinks are precision products and it is essential that they are fused on correct equipment. Under strict temperature control. The duration of time required is also programmed. During fusing, it is necessary to apply equal pressure over the component to ensure the following factors.

  • Intimate contact between top cloth and interlining.
