When choosing a vibration brick making machine, the focus is no longer solely on output per pallet. For many overseas buyers, a bigger concern is whether a single machine can produce paving bricks, solid bricks, and decorative concrete products while maintaining consistent density, surface quality, and dimensional accuracy — all while controlling energy consumption and operating costs.

Steam curing uses controlled heat and moisture to accelerate hydration. UNIK‘s delivered systems, including the 30-pocket finger car curing system for a Sri Lanka project (2025), achieve target strength within 10 hours.

A brick concrete mould represents a significant capital investment. Replacing a mould prematurely cuts into profit margins. Operating a worn mould beyond its useful life produces out-of-spec blocks, generates waste, and damages the block machine. The solution is systematic maintenance that extends mould life without compromising block quality.

Against the backdrop of modern municipal construction and prefabricated assembly methods, the demand for precast concrete components has surged dramatically. From blast barriers and drainage U-channels to box culverts and Lego-style blocks, precast elements are highly valued for their construction efficiency and consistent quality. As a critical link in concrete product machinery, the design precision and durability of precast concrete moulds directly determine both the cost and the quality of the final product.

Quanzhou, China – Fujian Unik Mould Technology Co., Ltd., founded in 2008 with over 15 years of export experience, today announced that its optimized hollow block moulding structure is delivering measurable improvements in efficiency and quality for customers across 28 countries. The optimized structure features precision-machined cavities with ±0.3mm tolerance, optimized clearance of 0.2-0.4mm between presser foot and cavity, and carburizing heat treatment achieving HRC59-62 surface hardness. Whole board flatness is maintained at ≤0.5mm. UNIK‘s facility in Quanzhou operates 27 wire-cutting machines, 4 large gantry machining centers, and advanced heat treatment equipment, with monthly mould output reaching 50 sets.

The mould directly shapes every block. Quality moulds use Cr12MoV or 9CrSi alloy tool steel with carburizing heat treatment. Surface hardness should reach HRC58-62 for wear resistance. Core hardness should stay at HRC35-40 for vibration absorption. Without proper heat treatment, moulds crack prematurely or wear unevenly.
