Aluminium die casting
High-pressure aluminium die casting for thin-walled components with complex geometry — shot weights from 50 g to 5 kg. Aluminium die casting shapes molten aluminium under high pressure into hardened steel dies, producing components with thin walls, complex geometry and surface finish that sand casting cannot reach. We work with shot weights from 50 grams to 5 kilograms across primary alloys like AlSi9Cu3, AlSi10Mg and AlSi12 — selected against the application's mechanical, thermal and corrosion requirements. Alloy choice is part of the engineering review, not assumed from the drawing. The wrong alloy produces parts that meet the geometric specification but fail in service — wrong stiffness, wrong fatigue resistance, wrong surface response after anodising. We close that gap before the tool is cut. Typical applications include enclosure housings, structural brackets, heat sinks, gearbox covers and load-bearing components for the appliance, tech, lighting and audio industries.

Zinc die casting
High-precision zinc die casting for small to medium parts with tight tolerances and fine surface finish. Zinc die casting handles applications where aluminium is not the right answer — components needing tighter dimensional tolerances, finer surface finish, higher detail resolution or the specific mechanical properties of zinc alloys like Zamak 5 and Zamak 3. The lower casting temperature extends tool life significantly, which makes zinc the economical choice at high volumes despite the higher material density. We use zinc casting where the application benefits from net-shape geometry with minimal post-machining, decorative surface quality, or integrated functional features that would otherwise require secondary operations. Typical applications include precision fittings, decorative hardware, locks and latches, instrumentation components and fine mechanical parts for design, lighting and consumer-facing assemblies.

Tooling, machining and finishing
Die development, CNC machining and surface treatment integrated into the same delivery — casting arrives finished, ready for assembly. A raw die casting is rarely the deliverable. The tool needs to be developed and qualified up front, the casting needs to be trimmed and machined to final tolerances on critical features, surface-treated for corrosion protection or aesthetic finish, and often combined with other components before it reaches the production line. We integrate these operations into the same job, scheduled and documented as one flow rather than four separate sub-contracts. Tool development, machining, surface treatment and assembly run on the same QA chain as the casting itself, with material traceability preserved end to end. For you, that means one purchase order, one point of contact and one set of inspection records — instead of coordinating multiple suppliers and absorbing the lead time between them.
Engineered before
it's cast.
Design for manufacturing
Most die casting designs come in with the geometry treated as if it could be machined from solid stock. Too often the draft angles, parting line, wall thickness uniformity and gating strategy haven't been considered — and the part either can't be cast soundly, or arrives with porosity, sink marks and dimensional variation that no amount of process tuning can eliminate.
​
We bring tooling engineering into the conversation early. Before the die is cut, our engineers review the geometry, wall thickness logic, draft angles, gate location and machining stock allowance — the decisions that determine whether the casting fills cleanly and whether it is economical to produce at volume.

The earlier we're involved, the more we can remove from your cost and rework. A 30-minute DFM session often saves weeks of iteration later.

CNC is rarely a standalone process. We combine it with casting, forming and finishing to deliver complete components — often in a single purchase order.

Die casting as one link in a complete supply chain.
Most suppliers sell die castings as raw shapes that someone else has to finish. We don't. At Pamatek, die casting sits inside an integrated flow that runs from alloy selection through tooling and casting to machining, surface treatment and assembly — managed by one team, documented through one QA chain, delivered on one purchase order.
​
That's the difference between buying a casting and buying a finished component ready for your production line — with the alloy choice, gating strategy and downstream operations engineered together rather than negotiated separately.
