CORETECH
CoreTech is DZanetech’s dedicated in-house core shop, developed as part of our forward integration strategy to offer foundries a reliable, high-quality source of sand cores for various casting applications. Strategically designed to support our clients' production needs, CoreTech combines advanced technology with technical expertise to deliver dimensionally accurate, high-strength cores — on time, every time.
Our facility is equipped to produce a wide range of cores using both Cold Box and No-Bake systems, ensuring flexibility for different moulding processes and metallurgical requirements. We work closely with foundries to manufacture custom cores according to their exact specifications, helping reduce downtime and improve casting efficiency.
WHAT CORETECH OFFERS
Custom Core Manufacturing
DZanetech offer tailored core-making services to match unique foundry specs, including binder preferences, sand types, and dimensional requirements.The custom core manufacturing service allows foundries to outscource their core production, reducing the burden of maintaining in-house core-making facilities.
By leveraging DZanetech's expertise and equipment, clients can focus on casting operations while DZanetech handles core production, ensuring consistency, reliability and quality. This service is particularly beneficial for foundries experiencing capacity constraints, workforce shortages or technical challenges in core manufacturing.

3D printing and rapid prototyping
As part of our forward integration strategy, DZanetech now offer 3D printing solutions for core boxes, patterns, and prototype validation. This allows foundries to test designs faster, reduce tooling costs, and improve turnaround times. Unlike traditional tooling methods, which often require long lead times and expensive metal tooling, 3D printing enables rapid design iteration and shorter development cycles.
Using state-of-the-art additive manufacturing technology, DZanetech can produce moulds and patterns directly from CAD models, allowing for quick modifications and alterations without the need to restart from scratch. This is particularly valuable in prototype development or when trialling new designs. If a pattern requires dimensional adjustments or if a defect is detected in the initial casting, the design can be revised and reprinted in a matter of hours – not weeks.
The 3D printing capability also opens the door to producing complex geometries that would be difficult or impossible to achieve through traditional methods. Whether you’re developing a one-off prototype or refining a complex shape, this process eliminates many of the limitations and inefficiencies associated with conventional mould production.
DZanetech’s team collaborates closely with clients to translate their design needs into functional 3D models, ensuring that every print aligns with casting specifications and performance requirements. With 3D printing, clients are empowered to innovate faster, test smarter, and produce with greater agility – ultimately reducing risk and increasing competitiveness in a demanding industry.
TECHNICAL PROBLEM-SOLVING SUPPORT.
Bring your challenges to DZanetech. Experts will help with casting defects, process inefficiencies, and technical troubleshooting – both on-site and in a lab environment.
MATERIAL AND EQUIPMENT TRIALS
Evaluate various ceramic sands, binders, and coatings before committing to large-scale orders. DZanetech’s in-house lab
conducts a wide range of tests including tensile strength, specific gravity, transverse strength, permeability, and comprehensive sand analysis – covering pH, AFS grain fineness, clay content, and loss on ignition (LOI). Receive detailed performance insights, comparative testing reports, and personalised recommendations to guide your selection process with confidence.
PERSONALISED CONSULTATIONS AND TRAINING.
One-on-one sessions with specialists to help optimise strength, reduce waste, and improve overall efficiency.
Training workshops are also available for upskilling your team.
