Production Capacity for Different Concrete Products
The production capacity of a block making machine is not determined by machine cycle time alone. Product dimensions, mold cavity arrangement, pallet configuration, concrete mix, operating conditions and working hours all affect the final output.
For the QT8-15, the current reference capacity is 17,000 pieces per 8-hour shift for 390 × 190 × 190 mm blocks.

What Can the QT8-15 Produce?
The QT8-15 can be configured with different molds for a range of concrete products. This allows one machine platform to support different product lines as market demand changes.
Hollow Concrete Blocks
Hollow blocks are commonly used for walls, partitions and general building construction. The required block dimensions and cavity arrangement determine the mold configuration and production capacity.
Solid Concrete Blocks
Solid blocks can be produced by using a suitable mold configuration. Product size, weight and required output should be confirmed before the mold is manufactured.
Concrete Pavers
The QT8-15 can also be configured for paving products where accurate dimensions, consistent compaction and repeatable molding are required.
Curbstones
Curbstones and other larger concrete products require dedicated molds and may require different pallet handling and downstream arrangements according to their dimensions and weight.
The machine's versatility comes from the combination of its forming system and interchangeable mold configuration, rather than from using one universal mold for every product.
Hydraulic Vibration Forming System
The QT8-15 combines hydraulic pressure with controlled vibration during the forming process.
Its rated hydraulic pressure is 31,5 MPa, while the vibration system provides a stated vibration force of 95 kN. The vibration frequency is adjustable within the specified 3800–4500 r/min range.
This forming method helps compact the concrete mixture inside the mold while maintaining a repeatable production cycle.
The actual product quality depends on more than machine pressure and vibration. Concrete mix design, aggregate grading, moisture content, mold condition and operating parameters also need to be matched to the product being manufactured.
Siemens PLC and Automatic Control
The QT8-15 uses a Siemens PLC and frequency conversion control system for automated machine operation.
The control system is designed to coordinate the forming sequence and provide more consistent control of the machine's operating parameters.
Key functions include:
Automatic production sequence control
Frequency conversion control
Controlled vibration operation
Hydraulic system coordination
Repeatable forming cycles
Simplified operator interaction
Automation can also reduce repetitive manual operations and help maintain a more consistent production rhythm during extended operation.
Heavy-Duty Machine Construction
The QT8-15 has a machine weight of approximately 14 tons, reflecting its heavy-duty construction for hydraulic and vibration forming.
The main frame uses 8 mm square tube steel to provide structural support during repeated forming cycles.
A rigid machine structure is important for maintaining alignment between the mold, pressing components and vibration system during continuous production.
For projects with long operating hours or higher production requirements, the machine foundation, installation area and maintenance access should be considered during factory planning.
QT8-15 Mold Configuration
The mold is one of the most important components affecting the final product.
Different molds determine:
Product dimensions
Number of cavities
Products formed per cycle
Block or paver shape
Product thickness
Surface pattern
Expected production output
Kimberly Machinery states that its molds use Q345B high-manganese steel with heat treatment, with a stated service life of more than 100,000 cycles. Actual mold life depends on material selection, production conditions, maintenance and operating practices.
Choosing the Right Mold
Before ordering the QT8-15, provide:
Product drawings or dimensions
Product type
Target production capacity
Required cavity arrangement
Product thickness
Surface or interlocking pattern, if applicable
This allows the machine and mold configuration to be checked together rather than treating the mold as a separate purchase after the machine has been selected.
Is QT8-15 the Right Machine for Your Production?
The QT8-15 is intended for manufacturers that need more production capacity and flexibility than a smaller block machine while still requiring a relatively compact forming system compared with higher-capacity industrial models.
It can be considered when your project requires:
Regular production of concrete blocks or pavers
Multiple product types using different molds
Automatic hydraulic vibration forming
Stable production cycles
Integration with batching and mixing equipment
A production setup that can be expanded with additional handling and automation equipment
The right machine should ultimately be selected according to target output, product dimensions, factory conditions, labor availability and investment plan.
For buyers comparing different models, Kimberly Machinery offers a broader range of machine de fabrication de blocs de béton configurations, including QT-series machines with different production capacities.
QT8-15 in a Complete Production Setup
The QT8-15 is the forming section of a concrete block manufacturing system. A complete plant normally requires equipment for material preparation, concrete mixing, block forming, pallet handling, curing and finished-product handling.
A typical process is:
Raw Material Storage → Batching → Mixing → QT8-15 Forming → Pallet Transfer → Curing → Palletizing → Packing
The exact equipment configuration should be determined by the required output, product range, factory layout and desired automation level.

Factory Requirements and Installation Planning
The QT8-15 itself measures approximately 9800 × 3600 × 2800 mm and weighs around 14 tons.
However, the machine footprint should not be treated as the total factory area required for production.
The plant layout should also provide space for:
Raw material storage
Batching and mixing
Machine operation
Fresh block transfer
Durcissement
Finished-product storage
Pallet circulation
Accès à la maintenance
Loading and transportation
Electrical Planning
The machine's stated total power is 44.9 kW.
The final electrical requirement should be confirmed according to the complete equipment configuration rather than the main machine alone.
Before installation, confirm:
Local voltage
Frequency
Three-phase power supply
Transformer capacity
Total line electrical load
Cable and electrical protection requirements
Kimberly Machinery can provide electrical load information for project planning after the equipment configuration has been confirmed.
Raw Materials and Concrete Mix
The QT8-15 works with properly prepared concrete mixtures based on the selected product and mold configuration.
Typical materials include:
Cement
Sand
Aggregates
Water
Fly ash or other supplementary materials where applicable
The mix design should be matched to the required product strength, dimensions and local raw materials. Consistent batching, aggregate grading, moisture control and mixing help maintain stable forming conditions.
For QT8-15 projects, the batching and mixing equipment should therefore be sized according to the machine's target output and product requirements.
