Injection molds for electronics and electrical: tight tolerances, complex geometries.
Molds for high-precision electronic and electrical components: connectors, case & cover, stators, rotors, switches and modular relays. Tight tolerances and complex geometries for every application.
Introduction
The electronic and electrical sector imposes some of the tightest machining tolerances in industry: complex geometries, precise fits and rigorous surface finishes are standard requirements for every component. The choice of steels follows the customer specification or is proposed by our team based on years of experience in the sector — including wear-resistant steels for glass-fiber-filled materials — ensuring flatness and dimensional stability over time. The finishes required by the customer are respected at every stage of construction, from machining to final testing.
We work with high-performance materials specific to electronics and electrical: ABS, PC, PA, PA66, PPS, PEEK and reinforced engineering polymers. We handle multi-cavity molds up to 64 cavities for high-volume production, with filling balancing and process control that ensure conforming parts throughout the life of the mold.
Technical features
From milling to EDM: precision at controlled temperature.
Building molds for the electronic and electrical sector requires advanced machining technologies. Finishing operations take place in a zone kept at a constant 22°C, with 3- and 5-axis centers equipped with automatic tool change and robots for part handling. Wire EDM is managed directly by the operators with in-machine programming; sinking EDM uses copper electrodes to achieve fine surface finishes down to VDI 19. Temperature-controlled CMM dimensional inspection checks critical dimensions in-house before assembly.

High-performance materials
PC, PPS, PEEK: high-performance materials for electronics and electrical.
The most widely used polymers in the electrical and electronic sector are PC, PA66+GF, PBT, POM and ABS. The choice depends on four key properties: electrical insulation, flame retardancy (UL94 V-0 rating), thermal resistance and dimensional stability for precise fits.
Each material has its preferred field of use: polycarbonate for sockets, switches and enclosures; glass-fiber-reinforced PA66 for contactors, stators and rotors, where stiffness and thermal resistance matter; PBT for relays and connectors thanks to its fast crystallization and electrical insulation; POM for bearings and low-friction components; ABS for plates and cases where aesthetic finish is the priority.

FAQ
Frequently asked questions
-
Do you build connectors with a pin pitch below 1 mm?
Yes. We build molds for connectors with a pin pitch down to 0.8 mm. Insert machining is carried out on wire EDM with a 0.002 mm resolution and temperature-controlled in-house CMM inspection. -
Do you handle materials such as PPS and PEEK for high-frequency connectors?
Yes. We have proven experience with PPS (mold temperatures 80-100°C, balanced hot runners) and PEEK. We know the process challenges: overheating degradation, pre-injection moisture absorption, anisotropic shrinkage of PPS. -
How many cavities can you handle on a single connector mold?
Up to 64 cavities on hot-runner molds for mass-production connectors. Rheological balancing design ensures symmetrical filling even at the peripheral cavities.
