The Evolution of Block Mould Design: From Manual to CNC Precision
Quanzhou, China – Fujian Unik Mould Technology Co., Ltd., a specialist in brick machines and high-precision moulds, reports a notable increase in order volumes from South American brick plants during the first half of 2026. The company, founded in 2010 and headquartered in Quanzhou – a historic manufacturing hub along the Maritime Silk Road – attributes this growth to its focus on precision engineering, which delivers measurable improvements in production efficiency and energy management for its customers.
This news highlights a critical but often overlooked factor in modern block production: the direct impact of mould design on energy consumption. A fundamental advantage of UNIK's approach lies in its advanced CNC-machined cavities and precision engineering. This level of accuracy ensures consistent block dimensions and smooth surfaces, which reduces material waste and machine strain . By optimizing the fit between the mould and the block machine, and ensuring precise tolerances (as tight as ±0.3mm), UNIK moulds allow for smoother, more efficient production cycles. Documented results from optimized mould structures show that cycle times can be reduced by 15-20%, and reject rates can be kept below 1% . Fewer rejected blocks and less machine resistance directly translate to lower energy consumption per block produced, a significant operational cost for any brick plant.
The growing demand from South America reflects an industry-wide shift that UNIK has championed: the evolution from manual mould-making to CNC precision. The company's long-term strategy focuses on solving real-world production challenges, such as premature cracking and inconsistent block dimensions . This is achieved by employing:
Superior Materials: Using high-grade, wear-resistant steel like 42CrMo and specialized tool steels, chosen based on the specific concrete mix for maximum longevity .
Advanced Heat Treatment: Applying a carburizing process to harden the mould surface (HRC58-62) while retaining a tough, impact-resistant core (HRC35-40), ensuring moulds consistently reach 80,000 to 100,000 production cycles .
CNC Machining and Compatibility: Producing moulds that integrate seamlessly with major international brick machine brands, reducing the need for costly retrofitting and ensuring optimal performance from the first cycle .
UNIK's expertise has already led to significant global partnerships, with exports reaching 28 countries . The company's product portfolio, which includes hollow block, interlocking paver, and hexagonal paver moulds, is designed to meet diverse construction needs from affordable housing to infrastructure projects .
The recent surge in South American orders underscores a global trend towards more efficient, durable, and technologically advanced block production solutions. As the construction industry increasingly prioritizes sustainability and operational efficiency, the choice of mould is becoming a strategic decision. By focusing on material science, manufacturing precision, and a comprehensive 12-month warranty with after-sales support, UNIK positions itself as a key partner for brick plants seeking to modernize their operations and reduce their energy footprint .
