A COMPREHENSIVE PROCESS
Polyester is a common type of material used for making buttons. A special sort of properties contained in Polyester makes it suitable for making buttons. To make coloured buttons, we use a variety of chemical dyes that are added to the polyester. While manufacturing the buttons, a chemical catalyst does the work of hardening the polyester, and wax.
Once the process of Button Blanking and Button Machining gets completed, buttons go through the finishing and polishing stage. Then, they are placed on a conveyor belt and visually inspected for defects. The inspector checks each button for flaws and remove any cracked or mis-cut ones. Excluding the defected ones, buttons are then ready for packaging and sale.
1. BUTTON BLANKING
Unsaturated Polyester Resin is mixed with various additives and pigments to the desired formulation to cast to sheets which are then perforated into blanks. Similarly, the raw materials are cast in form of rods which are then sliced into blanks
2. BUTTON MACHINING
The cured blanks are given shape and design from the turning machines (Button making machines). Turning of buttons are done by single side turning machines; where only the front of the button is turned or both side turning machines where both the sides of the buttons are turned.
3. POLISHING AND FINISHING
The buttons are then deburred, smoothened and polished in ball mills.
4. INSPECTION AND PACKING
After polishing, the buttons are inspected for breakage or any other faults, packed and sold.
