Power Selection Logic

Thin Sheet vs Thick Plate

Choosing the correct laser power starts with understanding the thickness range of the materials you process. Power determines cutting capacity, speed, and overall production efficiency.

For thin sheet metal, lower power machines (3kW–12kW) are sufficient and often more efficient. These machines provide high cutting speed, lower energy consumption, and reduced operating cost.

For thick plate applications, higher power is required to ensure full penetration and stable cutting. As thickness increases, insufficient power leads to:

• Slow cutting speed
• Incomplete penetration
• Poor edge quality

Power vs Thickness Reference

Power Range	Recommended Thickness	Application
3kW–6kW	1–12 mm	Thin sheet metal
6kW–12kW	10–25 mm	Medium thickness
12kW–20kW	20–40 mm	Heavy plate
20kW–30kW	30–60 mm	Industrial cutting
30kW–80kW	50–100 mm+	Ultra-thick plate

Selecting power based on actual material thickness ensures optimal efficiency and avoids unnecessary energy consumption.

Industrial vs Workshop Applications

Application environment also plays a key role in power selection.

For small workshops or flexible production environments:

• Lower power machines (3kW–12kW) are preferred
• Focus is on versatility and cost control
• Suitable for small batch production

For industrial-scale production:

• Medium to high power machines (12kW–80kW) are required
• Focus is on productivity and continuous operation
• Suitable for large batch and heavy-duty applications

Application Comparison

Scenario	Recommended Power	Focus
Small workshop	3kW–6kW	Flexibility
Medium factory	6kW–20kW	Balance
Heavy industry	20kW–80kW	Efficiency & capacity

Understanding production scale helps avoid over-investment or under-capacity.

Model Matching

3015H for Sheet Metal

The 3015H model is the standard configuration for sheet metal processing. With a working area of 3000×1500 mm, it is ideal for cutting standard sheet sizes.

Typical characteristics:

• Best matched with 3kW–12kW power
• High speed for thin and medium sheets
• Suitable for precision parts and batch production

3015H Application Positioning

Feature	Value
Working area	3000×1500 mm
Recommended power	3kW–12kW
Application	Sheet metal processing

This model is widely used in industries such as electrical cabinets, furniture manufacturing, and precision metal parts.

6025H–8025H for Heavy Industry

For larger plates and heavy-duty applications, 6025H and 8025H models are more suitable.

• 6025H: 6000×2500 mm working area
• 8025H: 8000×2500 mm working area

These machines are designed for:

• Large plate cutting
• Thick material processing
• Structural steel fabrication

Large Format Model Comparison

Model	Working Area	Recommended Power	Application
6025H	6000×2500 mm	6kW–30kW	Heavy fabrication
8025H	8000×2500 mm	20kW–80kW	Large structures

Choosing the correct machine size ensures efficient material handling and reduces repositioning time.

High Power Selection

When to Choose 30kW–80kW

High power laser cutting machines (30kW–80kW) are designed for demanding industrial applications where thick plate processing and high productivity are required.

You should consider high power systems when:

• Cutting thickness exceeds 40–50 mm regularly
• Production requires high throughput for thick materials
• Replacing plasma or flame cutting processes
• Working in industries such as shipbuilding, heavy machinery, or steel structures

High Power Application Comparison

Scenario	Recommended Choice
Thin sheet production	Not required
Mixed production (thin + medium)	12kW–20kW
Thick plate production	20kW–30kW
Ultra-thick industrial cutting	30kW–80kW

High power machines provide:

• Faster cutting speed for thick plates
• Reduced processing time
• Improved edge quality compared to traditional methods

However, they also require:

• Higher initial investment
• Stronger infrastructure (power supply, cooling, gas system)
• More advanced maintenance management

Choosing the right laser power from 3kW to 80kW depends on three key factors: material thickness, production scale, and application type.

• For thin sheet metal, 3kW–12kW systems offer the best balance of speed and cost
• For medium to heavy plates, 12kW–30kW provides strong performance
• For ultra-thick materials and heavy industry, 30kW–80kW is the optimal choice

Matching power with machine model—such as 3015H for sheet metal and 6025H–8025H for heavy applications—ensures maximum efficiency and return on investment.

By selecting the appropriate power level based on real production needs, manufacturers can achieve higher productivity, better cutting quality, and lower overall operating costs.
