Product advantages

Advantage of QT12‑15C Automatic Hollow Block Forming Machine

1. Synchronous Variable‑frequency Table‑vibration System, Optimized For Hollow‑block Core‑mold Forming, Less Reject Loss

QT12‑15C adopts synchronous variable‑frequency table‑vibration design optimized for hollow‑block core‑mold cavity. Low‑frequency vibration in feeding phase pushes material fully fill narrow gaps around core molds to avoid partial material shortage. High‑frequency synchronous excitation removes trapped air bubbles in forming stage together with stable 21 MPa hydraulic pressing. Finished hollow blocks feature sharp cavity outline and even wall‑thickness with high density consistency. It reduces rejects such as cavity under‑filling, looseness and corner chipping. Finished blocks meet international building‑wall acceptance standards, cut raw‑material waste and guarantee quality for bulk hollow‑block orders.

2. Heavy‑duty Welded Frame & European‑tech Universal Drive Shaft, Low Failure Rate For Multi‑shift Hollow‑block Production

The main frame is fully welded by 12×12cm high‑quality square steel tubes from Laigang and Jigang steel mill, delivering high rigidity to resist continuous high‑frequency impact vibration during hollow‑block mass‑production. Universal drive‑shaft with proven European‑technology transfers power evenly and prevents motor burnout caused by unbalanced load. Reinforced mechanical design lowers damage risk of key components. It minimizes unplanned downtime and prevents order‑delay losses caused by equipment failure.

3. Taiwan Calyca Full‑set Hydraulic Components, Stable Pressure Output & Consistent Hollow‑block Quality

Full hydraulic system applies original Taiwan Calyca hydraulic parts with excellent sealing property and anti‑fatigue performance. It adapts to long‑time high‑frequency pressing for hollow‑block production and maintains stable pressure without pressure‑release or oil‑leakage. Stable hydraulic force guarantees uniform pressing effect for every mold and small dimension deviation for finished hollow blocks. It cuts frequent maintenance and spare‑part replacement cost in later‑stage operation.

4. Siemens Intelligent Control System With Remote Monitoring & Fault Diagnosis, Lower Reliance On Skilled Workers

Complete imported Siemens electrical components and HMI touch‑screen realize fully‑automatic pallet feeding, material feeding, vibration‑press forming, demolding and block discharging. Multiple groups of hollow‑block process parameters can be stored and one‑click recalled for product change‑over. Built‑in fault warning and remote‑monitoring‑diagnosis function allow overseas users to check machine status remotely without waiting for on‑site technicians. Electrical interlock prevents core‑mold collision caused by mis‑operation. Ordinary operators can handle mass hollow‑block production after simple training without senior skilled workers and save labor‑management cost.

5. Carburizing‑treated Manganese‑steel Hollow‑block Special Molds & Large 1300×900 mm Pallet, High Output & Diversified‑order Compatibility

Special hollow‑block molds adopt manganese‑steel with carburizing heat‑treatment and precise wire‑cutting. Core‑molds feature high hardness, wear‑resistance and impact‑resistance, keeping consistent cavity dimension after long‑time continuous production. Large‑size 1300×900 mm pallet supports more hollow‑block cavities per cycle with 15‑25 s molding cycle to improve hourly output. Wearing mold parts can be replaced separately instead of whole‑set replacement to cut consumable cost. Beside hollow blocks, it can produce standard bricks and grass blocks by mold swap. Optional face‑mix system expands production capacity for color pavers, improving return‑on‑investment.

6. Wide Raw‑material Compatibility, Utilize Local Industrial Residues To Reduce Hollow‑block Raw‑material Expense

Besides conventional sand, stone powder and cement, this machine can process fly ash, furnace slag, gangue, expanded perlite and other industrial residues for hollow‑block manufacturing. Customers can make full use of locally‑available waste materials and reduce cement dosage while guaranteeing block compression strength. Local‑resource utilization lowers long‑distance procurement cost and strengthens price competitiveness of finished hollow blocks.

7. Modular Split‑type Main‑machine, Container‑shipping Friendly, Pre‑delivery Full Test & Reliable Spare‑part Support

QT12‑15C forming main machine adopts split‑modular structure for convenient sea‑container transportation. Complete electro‑hydraulic joint test is finished before factory delivery. After on‑site positioning, leveling, power and pipe connection, mass hollow‑block production can be launched with simple commissioning. Original spare‑parts including universal drive shafts, Calyca hydraulic kits, vibration assemblies and hollow‑block core‑molds are continuously supplied to guarantee stable mass‑production and on‑time order fulfillment.
