Quanzhou Hawen Machinery has recently completed the production and shipment of two customized Hollow block moulds for a customer in Thailand. Both moulds are designed for a Poyatos Novabloc concrete block-making machine using 1400 × 900 mm production pallets.

Overview of Hawen Machinery' s Block Molds
Located in Quanzhou, China, Hawen Machinery specialize in producing concrete block molds for global markets. With over a decade of experience, they craft molds for hollow blocks, interlocking pavers, and curb stones, compatible with top-tier machines like Poyatos, MASA, and HESS. Using high-grade materials such as 16# manganese steel and NM500, Hawen' s molds achieve a lifespan of 80, 000 to 120, 000 cycles, blending durability with precision engineering.

To meet the customer’s different production requirements, one mould produces 26 blocks per cycle, while the other produces 28 blocks per cycle. The optimized mould layouts help the customer achieve high production capacity while maintaining consistent block dimensions and reliable forming quality.

Project Overview

• Destination: Thailand

• Product: Hollow block moulds

• Quantity: 2 sets

• Compatible machine brand: Poyatos Novabloc

• Production pallet size: 1400 × 900 mm

• Output of the first mould: 26 pieces per cycle

• Output of the second mould: 28 pieces per cycle

• 

Customized Design for Poyatos Novabloc Block Machine

Every concrete block machine has specific requirements regarding mould dimensions, installation points, vibration parameters and production pallet size. Before manufacturing, Hawen Machinery’s technical team carefully reviewed the customer’s machine specifications and  block samples.

The two moulds were then customized to match the customer’s Poyatos machine and 1400 × 900 mm production pallets. Special attention was given to cavity arrangement, block spacing and mould structure so that 26 and 28 blocks could be formed efficiently in each production cycle.

High-Capacity Hollow Block Production

Hollow blocks are widely used in floor and roofing systems. Accurate dimensions, uniform shape and sufficient strength are therefore essential for stable installation and reliable construction performance.

The first mould features 26 cavities, producing 26hollow blocks in one cycle. The second mould has an optimized 28-cavity layout, allowing the customer to manufacture 28 blocks per cycle. These high-capacity designs help improve daily output and make better use of the Poyatos machine’s available moulding area.

Precision Manufacturing and Quality Inspection

During production, the main mould components were precisely processed to ensure accurate cavity dimensions and a proper fit with the block-making machine. Careful welding, machining and assembly help maintain the structural stability of the mould under continuous vibration and compression.

After assembly, both hollow block moulds underwent detailed quality inspections. The Hawen Machinery team checked the mould dimensions, cavity layout, tamper-head alignment, installation points and overall compatibility with the Poyatos machine.

These inspections ensure:

• Consistent Hourdis block dimensions

• Uniform block shape and clean edges

• Smooth mould filling and demoulding

• Accurate alignment between the mould box and tamper head

• Reliable performance during continuous production

• 

Secure Packing and Shipment to Thailand

After passing the final inspection, the two moulds were carefully cleaned and protected against corrosion. Secure export packing was used to protect the moulds from impact, moisture and damage during international transportation.

The two high-capacity Hollow block moulds have now been shipped to Thailand and will support the customer’s concrete block production with outputs of 26 and 28 pieces per cycle.

Customized Concrete Block Mould Solutions from Hawen Machinery

This shipment once again demonstrates Hawen Machinery’s ability to design and manufacture customized concrete block moulds for different international machine brands and production requirements.

In addition to Poyatos machines, Hawen Machinery can manufacture moulds compatible with various European and international concrete block-making systems. Available mould types include hollow block moulds, solid block moulds, Hourdis block moulds, paving block moulds, interlocking block moulds and curbstone moulds.

If you need customized block moulds for a Poyatos machine or another concrete block-making machine, please provide the machine model, pallet size, block drawing and required output per cycle. Hawen Machinery’s technical team will develop a suitable mould solution for your production needs.

Ultimately, this cooperation reinforces a simple but critical truth in industrial manufacturing:
true reliability is not defined by promises, but by precision that performs consistently in production.
