High-performance steel molds for producing up to 20 rings per shift
🏗️ We manufacture:
Heavy-duty vibroforms for the production of reinforced concrete well and sewer rings (KS-type), available in the following diameters:
800 mm
1000 mm
1500 mm
2000 mm
All dimensions comply with GOST 8020-2016 and are compatible with EN 1917 (for manhole components in the EU).

✅ Key Advantages:
High concrete compaction due to powerful vibration
Accelerated setting for faster demolding
Reinforced construction ensures long service life
Easy to operate with standard lifting gear
Compact design — perfect for production sites or precast yards
Designed for compliance with GOST 8020-2016 and EN 1917
🔁 Production Cycle:
Fill the mold with concrete
Activate vibration (high compaction begins immediately)
After 5–10 minutes, use a hoist to remove the inner core
After ~15 minutes, remove the outer ring, reset the mold, and repeat
🎯 Up to 20 rings per day per mold!
