SAW CUTTING |
 |
SINSO ACP CAN BE CUT BY USING WOODWORKING OR METALWORKING SAWS. THE SUPER FINE CUTTING BLADE IS RECOMMENDED TO PREVENT EDGE RAGGED. |
BENDING AND CURVING |
 |
SINSO ACP CAN BE BENT BY USING THREE-POINTED OR THREE-ROLLERED MACHINE. ALSO SINSO ACP CAN BE BRAKE FORMED FROM 0 TO 90 DEGREE BY USING HYDRAULIC BRAKE PRESS. |
ROUTING |
 |
SINSO ACP CAN BE ROUTED BY USING CIRCULAR SAW WITH STANDARD BITS 90 TO 110 DEGREE. THE BOTTOM OF GROOVE IS BETTER TO BE BETWEEN 1 AND 2 MM. AND THE REMAINING PE CORE IS RECOMMENDED TO BE 0.2 MM - 0.5 MM SAME AS THE ALUMINIUM SKIN AFTER ROUTE. |
WELDING |
 |
SINSO ACP EDGES CAN BE WELDED BY USING THE POLYTHYLENE ROD AND THE HOT WELDING TOOL. |
PUNCHING |
 |
HOLES CAN BE MADE BY PUNCHING MACHINE. |
