UNIK's factory is located in Quanzhou, Fujian Province, covering an area of over 12,000 square meters. Below is an on-site record of the production workshop.
CNC Machining Center – The workshop is equipped with 4 large gantry machining centers and 4 advanced CNC programming machining centers. These machines perform rough and finish machining of mould cavities, achieving positioning accuracy of ±0.005mm.
Wire Cutting Workshop – Equipped with 27 wire cutting machines for precision contour machining of mould cavities. Cavity surfaces achieve Ra 1.6 finish without secondary finishing.
Heat Treatment Workshop – Equipped with advanced box-type fully automatic heat treatment equipment, capable of carburizing, nitriding, and carbonitriding processes. Furnace temperature uniformity is controlled within ±5°C, ensuring consistent heat treatment for every mould.
Inspection Room – Equipped with CMM, hardness tester, roughness tester, and a full set of metal inspection equipment. Every mould undergoes final inspection here before shipment.
The raw material storage area is clearly organized on the factory floor. UNIK primarily uses 42CrMo forged steel and Mn18 alloy steel. All steel materials come with material certificates traceable to the original mill heat number.
Step 1: Drawing Confirmation
After the customer provides the machine model, block drawing, or sample, UNIK engineers complete 3D modeling and produce machining drawings within 48 hours. Drawings are submitted to the customer for signature approval before production begins.
Step 2: Cutting and Rough Machining
Based on the drawing dimensions, steel is cut to the required blank size using a band saw. Blanks are machined with allowance to compensate for potential deformation during subsequent heat treatment.
Step 3: CNC Finish Machining
Rough-machined blanks enter the CNC machining center for finishing. Cavity dimensions are controlled to ±0.1mm tolerance. Draft angle is machined to 1.5 degrees per side. Corner radius is machined to 3-5mm. Surface finish on critical areas reaches Ra 1.6.
Step 4: Heat Treatment
Finished moulds enter the heat treatment workshop. The standard process involves vacuum quenching at 980°C followed by tempering at 580°C. Surface hardness reaches HRC58-62, while core hardness remains at HRC35-40. For high-wear applications, core pins receive additional nitriding treatment, forming a diffusion layer of at least 0.03mm.
Step 5: Grinding and Polishing
Heat-treated moulds undergo surface grinding. Whole board flatness is controlled to ≤0.5mm. Cavity surfaces are hand-polished to Ra 0.8µm or better, ensuring smooth demolding.
Step 6: Assembly and Inspection
After core pins are installed, all critical dimensions are inspected using a CMM — cavity dimensions, core pin positions, and mounting hole locations. Upon passing inspection, the mould receives anti-rust oil coating and is packed into a wooden crate for shipment.

Case Study 1: Kenya Affordable Housing Project
Customer Background – A construction company in Kenya contracted for a government affordable housing project, requiring approximately 500,000 interlocking blocks annually.
Challenge – The customer's existing moulds produced blocks with inconsistent interlocking features, resulting in gaps and leaning during wall assembly.
Solution – UNIK supplied a three-cavity interlocking block mould made of 42CrMo steel with carburizing heat treatment, with core pin alignment tolerance controlled to ±0.2mm.
Result – Consistent interlocking features were achieved. Wall assembly speed increased by 30%. The customer subsequently ordered 5 additional mould sets.
Case Study 2: Saudi Arabia Retaining Wall Project
Customer Background – An infrastructure contractor in Saudi Arabia needed to produce heavy-duty interlocking blocks for highway slope protection.
Challenge – The local concrete mix contained highly abrasive aggregates, causing ordinary moulds to last less than 50,000 cycles.
Solution – UNIK supplied a tool steel mould with additional nitriding treatment on core pins, achieving surface hardness above HRC62.
Result – Mould life reached 100,000 cycles. The customer has added UNIK to its approved supplier list.
Case Study 3: Philippines Paver Block Producer
Customer Background – A paver block producer in Manila, Philippines, with a daily output of approximately 4,000 blocks.
Challenge – The customer operated a HESS block machine, but previously purchased moulds had mismatched mounting hole patterns, requiring 2 hours of adjustment per mould change.
Solution – UNIK precisely replicated the mounting interface based on the customer's machine nameplate photo and old mould.
Result – The new mould achieved plug-and-play installation, reducing mould changeover time from 2 hours to 15 minutes.

Trend 1: Interlocking Blocks Shifting from "Functional" to "Durable"
Over the past five years, market requirements for interlocking blocks have shifted from "does it interlock" to "does it maintain interlock under harsh conditions." This has driven higher mould precision standards. UNIK has observed that the proportion of orders requiring core pin alignment tolerance within ±0.2mm has increased from 35% in 2021 to 58% in 2026.
Trend 2: Quick-Change Moulds Becoming Standard
Traditional mould changeovers take 2-4 hours, including disassembly, cleaning, reinstallation, and adjustment. Quick-change mould systems complete changeovers within 15-30 minutes. This technology has highest penetration in the Middle East and Southeast Asian markets, reaching 72% and 58% respectively. UNIK's UNT400/600/800 platforms all feature standardized interfaces supporting quick-change.
Trend 3: Data-Driven Mould Management
