Production Requirements

Material Type and Thickness

You need to pick a slitting line that matches your copper. Copper comes in many types and thicknesses. Each type needs special handling. Most slitting lines work best with copper between 0.0078″ and 0.125″ thick. If your copper is thinner than 0.002″, razor slitting is a good choice. For copper thicker than 0.250″, you need to use shearing. The table below shows how the type and thickness of copper matter:

Factor	Details
Thickness suitability	Slitting works for copper from 0.001″ to 0.250″; razor slitting for less than 0.002″
Thickness limitation	Most slitting machines are best for copper under 0.500″ thick
Thicker copper (>0.250″)	Shearing is better because of machine limits
Copper type	Soft copper works well with shear slitting
Material form	Slitting is best for copper that comes in coils
Edge quality	Slitting gives smooth, clean edges without burrs
Blade maintenance	Copper can wear blades, so skilled care is needed

Tip: Always check what thickness your Copper Coil Slitting Line can handle before you buy.

Coil Width and Weight

You should think about how wide and heavy your copper coils are. These things decide how big and strong your slitting line needs to be. The tables below show common sizes:

Slitting Line Type	Coil Width Range (mm)	Coil Weight Range (tons)
CR Slitting Line	200 – 1800	0.5 – 35
HR Slitting Line	300 – 1800	1 – 35

 

Parameter	Range
Width	3 mm to 1220 mm
Thickness	0.15 mm to 6 mm

• The widest coil sets the biggest width your machine must handle.
• Coil weight changes the size of the decoiler, slitter head, and recoiler.
• Knowing the right width and weight helps you pick the best machine and saves money.

Production Volume

Your output goals help you know what machine you need. If you want to make a lot, you need a slitting line that can hold bigger coils, run faster, and has more automation. The table below shows how your goals change what you need:

Specification Aspect	Details and Relation to Output Goals
Coil Weight	Up to 20 tons lets you process more copper at once.
Coil Width	Wide range (800-1600 mm) means you can use big coils and work faster.
Line Speed	Up to 120 m/min helps you finish jobs quickly.
Slitting Accuracy	±0.03 mm keeps your cuts neat, even at high speed.
Automation	PLC automatic control makes work easier and saves time.

Note: When you know your production volume, suppliers can help you pick the best Copper Coil Slitting Line.
