What Are Multi-Level Water Circuits?
Multi-level water circuits are complex internal channels drilled into components, often used in industries like toolmaking, injection moulding, and heat transfer systems. These circuits allow liquid — usually water — to flow through the part in a controlled way, typically for cooling or temperature regulation. Creating them requires advanced drilling techniques to achieve precise depth control, angle transitions, and internal connectivity.
LDC Engineering’s Expertise in Water Circuit Drilling
At LDC Engineering Ltd, drilling multi-level water circuits is a specialist service. Using their deep hole drilling and gun drilling technology, they can create straight and angled bores, stepped or staggered channels, interconnected paths at different depths, and accurate coolant paths in mould tools or dies. This work demands tight tolerances, skilled planning, and high-end machinery — all of which LDC Engineering provides in-house.
Drilling Capacity That Supports Complexity
LDC offers gun drilling up to 38mm in diameter to 4m depth, and deep hole drilling up to 68mm in diameter to 2m depth. This flexibility allows them to produce both simple heater holes and highly intricate cooling channels within large or high-performance components.
Applications of Multi-Level Water Circuits
This form of drilling is essential in toolmaking and mould production, where it helps maintain temperature in plastic or die-cast moulds. It is also widely used in automotive and motorsport for precision cooling in engine blocks and housings, as well as in aerospace and defence sectors for thermal management in components under stress. In industrial equipment, internal temperature control improves both safety and performance. These circuits improve component reliability and extend operating life.
Reliable Precision for Complex Components
LDC Engineering delivers accurate, specification-led water circuit drilling for toolmakers, manufacturers, and engineers across the UK. Their expert-led process ensures performance, precision, and consistency every time.
