Cement Hollow Block Mould for Block Making Machine

PRO is a Chinese manufacturer and supplier of concrete block moulds for automated block-making machines. The mould solutions are designed for MASA, HESS, and other compatible equipment, covering standard and customized hollow block production requirements.

This Cement Hollow Block Mould for Block Making Machine uses Hardox steel and manganese steel in key wear areas. It is available for 4", 6", 8", and 12" blocks with 2-hole, 4-hole, 6-hole, and 8-hole configurations. The stated service warranty is up to 90,000 cycles.

Main Specifications

Final machine compatibility and mould dimensions should be confirmed against the customer's machine model and approved technical drawing.

Mould Design

Wear-Resistant Cores

The mould cores and core bars are designed for repeated pressure and friction during block production. Hardox steel is used for key wear-resistant components, while the mould core receives carburizing heat treatment.

The specified hardness is 60–65 HRC, with a 1.2–1.35mm carburizing layer. This structure is intended to reduce premature wear and support longer tooling service.

Replaceable Components

The mould uses replaceable mould cores and core bars. When key wearing parts reach the end of their service condition, individual components can be replaced instead of automatically replacing the complete mould.

This structure can reduce maintenance costs and production downtime for manufacturers operating block machines continuously.

Interchangeable Base Plates

Interchangeable base plates are available for applicable mould designs. Changing the base plate allows different block sizes or profiles to be produced without replacing the entire mould assembly.

The available configuration depends on the machine model and required block design.

Dimensional Accuracy

Mould Tolerance

Mould dimensional accuracy directly affects the consistency of finished concrete blocks. Cavity dimensions, core position, hole geometry, wall thickness, and base plate alignment therefore need to match the approved block drawing.

PRO does not apply one universal tolerance to every mould because dimensions and machining requirements vary according to the block model and machine. The final tolerance is confirmed according to the approved technical drawing and production specification.

For projects requiring a defined tolerance, such as ±0.1mm or ±0.2mm, the requirement should be included in the RFQ or technical drawing before production.

Mould Comparison

PRO vs. Standard Moulds

For block manufacturers, the purchase price is not the only factor affecting mould cost. Service life, replacement parts, dimensional consistency, and maintenance requirements can have a greater impact on long-term production costs.

The 90,000-cycle figure represents the stated PRO service warranty and should not be considered a universal production-life guarantee. Actual service life depends on concrete mix, machine pressure, vibration, production frequency, cleaning, maintenance, and operating conditions.

A meaningful price comparison should use the same machine model, mould dimensions, steel materials, block configuration, quantity, and service requirements.

Assembly Structure

Screw-Locking

The freely assembled screw-locking structure simplifies installation, disassembly, and replacement of wearing components. It is suitable for customers who need regular mould maintenance during continuous production.

Welding Assembly

Welding assembly is also available when required by the customer's machine configuration or mould design. PRO can provide welding and assembly design based on technical drawings.

Block Applications

Hollow Construction Blocks

Cement hollow blocks are widely used as walling and infill materials in construction. Their hollow structure can reduce weight and provide useful thermal and sound insulation properties.

Insulating Blocks

Different cavity configurations can be used for block designs requiring lower weight or improved insulation performance. The final block performance depends on concrete mix, cavity design, production conditions, and construction requirements.

Decorative Blocks

Concrete blocks can also be produced for architectural and decorative applications where block shape, profile, and surface appearance are important.

Machine Compatibility

MASA and HESS

The Cement Hollow Block Mould for Block Making Machine is designed for MASA and HESS block-making machines. Other machine models can also be evaluated based on machine drawings, existing mould samples, and finished block dimensions.

For replacement orders, buyers should provide the machine model, mould dimensions, pressure head specifications, base plate details, and block drawing whenever available.

Custom Production

Block Size and Holes

The available designs cover 4", 6", 8", and 12" blocks with 2-hole, 4-hole, 6-hole, and 8-hole configurations.

Custom cavity arrangements, dimensions, and profiles can be evaluated for projects with non-standard block requirements.

Mould Drawings

PRO can develop customized moulds using machine drawings, existing mould samples, finished block samples, or technical drawings as references.

For large-volume projects, customers can specify dimensional tolerances, steel grades, heat treatment, assembly method, and inspection requirements before production.

Production and Maintenance

Core Replacement

Fast-replaceable mould cores and core bars simplify routine maintenance. Replacing worn components individually can help reduce downtime compared with changing a complete mould.

Inspection

Before delivery, customized moulds can be checked against the approved drawing. Inspection requirements may include cavity dimensions, core alignment, hole configuration, base plate positioning, and overall mould dimensions.

Procurement Information

Before ordering a Cement Hollow Block Mould for Block Making Machine, buyers should confirm the block machine brand and model, finished block size, number of holes, mould dimensions, steel material, required hardness, heat treatment, assembly method, and expected production volume.

For customized orders, providing machine drawings or photographs of the existing mould can help reduce compatibility risks.

PRO provides mould manufacturing, assembly and welding design, technical consultation, and customized tooling for standard and high-volume block production.

Frequently Asked Questions

How long can the mould last?

The mould has a stated service warranty of up to 90,000 cycles. Actual service life depends on the concrete mix, machine pressure, vibration, production frequency, maintenance, and operating environment.

What is the mould hardness?

The specified hardness is 60–65 HRC. The mould core also has a 1.2–1.35mm carburizing layer to improve surface wear resistance.

What dimensional tolerance can PRO provide?

Tolerance is confirmed according to the mould drawing and machine requirements rather than using one fixed value for every product. If a project requires ±0.1mm, ±0.2mm, or another specific tolerance, the requirement can be included in the technical drawing or RFQ for confirmation.

Can worn mould parts be replaced separately?

Yes. The design allows key components such as mould cores and core bars to be replaced separately. This can reduce maintenance costs and avoid unnecessary replacement of the complete mould.

Which block sizes can be produced?

Available block sizes include 4", 6", 8", and 12", with 2-hole, 4-hole, 6-hole, and 8-hole configurations. Customized dimensions and cavity designs can also be evaluated.

Is the mould compatible with MASA and HESS machines?

Yes. The Cement Hollow Block Mould for Block Making Machine is designed for MASA and HESS block-making machines. Compatibility with other machines can be confirmed using the machine model, mould drawings, or existing mould samples.

Can PRO customize a mould according to our machine?

Yes. PRO can customize mould dimensions, block cavities, hole configurations, assembly structures, and other tooling requirements according to machine drawings and finished block specifications.

What information is needed for a quotation?

Buyers should provide the machine brand and model, block dimensions, hole configuration, mould size, required material, hardness, production quantity, and any dimensional tolerance or inspection requirements. An existing mould drawing or block drawing is helpful for accurate quotation and compatibility confirmation.
