What is SLS?
A Groundbreaking Innovation to
Solve the Labor Shortage in the Construction Industry
SLS Construction Collaborative Robot
Speed Leveling System
The emergence of SLS Construction Collaborative Robot aims to:
- Eliminate the repetitive and strenuous task of pushing heavy mortar
- Reduce the need for manual labor in leveling and smoothing processes
With SLS, anyone can easily take on plastering work.
The All-New 3K Experience with SLS:
Hard Work → Effortless
Dirty → Clean
Dangerous → SafeNot only young workers but also women and the mid-life generation
(50-65 years old) can easily participate in this field.
Wall surface leveling is a crucial step in construction.
Traditionally done manually, it is now revolutionized with:#SLS Automated Collaborative Leveling
- Enhances precision and flatness
- Reduces labor requirements
- Improves construction quality and project efficiency
Fast & Efficient –
SLS Automatic Leveling Method
Cement mortar or gypsum requires a high level of skill and learning to be properly leveled, making manual finishing challenging.
With SLS, the process integrates:
A spraying machine for application
A mechanized automatic cutting system
A laser-guided inspection system
Through a simple training process, operators can efficiently achieve fast, easy, and high-quality finishes.
Proven Efficiency in Real-World Applications
A 4-person team equipped with a complete SLS system can finish approximately 120-160 pings (396-528 m²) per day in a single operation, producing a smooth plastered surface.
This method is 5-7 times more efficient than traditional techniques and eliminates the need for highly skilled craftsmen.
