At Plexnetic, we specialise in high-performance mould tool design and manufacture for resin casting and encapsulation applications. From low-volume prototyping to full-scale production, our in-house capabilities ensure precise, repeatable tooling built to support high-, medium-, and low-voltage component encapsulation.
Precision mould tools — engineered from concept to completion.
Whether you’re prototyping or scaling up for production, we understand that the performance of your mould tool directly impacts the quality, repeatability, and cost-efficiency of your final component. That’s why we treat tool design not as a support function — but as a critical engineering discipline.
1.
Design That Anticipates Reality
Every successful mould tool starts with intelligent design. At Plexnetic, we use AutoCAD to produce precise 3D mould layouts that anticipate the physical and production realities of resin encapsulation. Our design process ensures:
Optimised geometry and tolerancing for clean demoulding
Resin and material compatibility engineered from the outset
Custom features such as vents, gates, and inserts tailored to performance needs
This design-first approach lays the foundation for reliable, repeatable tooling across high- and low-voltage component applications.

In-House Tooling Manufacture
Our in-house toolmaking capabilities give us full control over precision, quality, and turnaround times. Within our dedicated machine shop, we combine advanced equipment with expert craftsmanship to deliver production-ready tooling:
3-axis CNC milling for accurate cavity machining
Precision turning and lathe operations for circular and concentric features
Shot blasting and surface finishing to ensure clean, ready-to-use moulds
Fixture and jig design for consistent, repeatable tool performance
Our integrated feedback loop between design and manufacture ensures fast iteration, full traceability, and reliable outcomes for every project.

From Design to Delivery – All Under One Roof
By managing both mould tool design and manufacture in-house, Plexnetic ensures alignment between engineering intent and production reality. This integrated approach delivers:
Shorter lead times through streamlined coordination
Improved consistency across prototype and full-scale runs
Full traceability of materials and processes
Our tooling is engineered to scale — supporting everything from the first part to high-volume production with repeatable, high-quality results.
We follow best practices in resin mould tool design, ensuring material compatibility and stress-free demoulding. Industry guides like TechSil’s Potting and Encapsulation Overview outline similar approaches.
