it's cast.
Design for manufacturing
Most 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 transitions and feeder placement haven't been considered — and the part either can't be cast soundly, or arrives with porosity, shrinkage cavities and dimensional variation that no amount of process tuning can eliminate.
We bring casting engineering into the conversation early. Before the pattern is cut, our engineers review the geometry, wall thickness logic, gating strategy, feeder layout and machining stock allowance — the decisions that determine whether the casting solidifies 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.

Sand casting
Sand casting for complex geometries and larger sections — components from 500 g to 200 kg in cast iron, steel and bronze. Sand casting shapes molten metal in a sand mould produced from a pattern, delivering complex geometries, larger sections and weight ranges that other casting methods cannot economically reach. We work with weight ranges from 500 grams to 200 kilograms across grey iron, ductile iron, cast steel and bronze grades, with near-net geometries that reduce downstream machining stock. Pattern design is engineered against the part geometry, expected volume and mechanical properties — not pulled from a generic library. Draft angles, parting line placement, gating system and feeder layout are decided up front, which determines whether the casting solidifies cleanly and whether the mechanical properties are consistent across the run. Typical applications include structural housings, pump bodies, gearbox cases and load-bearing components for the wind, fitness and industrial equipment industries where complex geometry and material strength matter together.

Investment casting
Investment casting for tight-tolerance components with fine surface finish — small to medium parts in stainless, alloy steel and bronze. Investment casting uses a wax pattern coated in ceramic shell to produce components with tight dimensional tolerances, fine surface finish and intricate geometry that sand casting cannot match. The process is the right answer when the part needs minimal machining, complex internal features or surface quality that justifies the higher per-part tooling cost. We work with small to medium components in stainless steel, alloy steel and bronze grades, with cast tolerances tight enough that many features come off the casting fully finished. The volume case is built into the engineering review — investment casting pays back when the alternative is heavy machining from solid stock or multi-operation fabrication. Typical applications include precision fittings, instrumentation housings, valve bodies and components for design, lighting and tech assemblies where surface quality and dimensional accuracy are decisive.

Heat treatment and machining
Stress relief, normalising, machining and surface treatment integrated into the same delivery — casting arrives finished and ready for assembly. A raw casting is rarely the deliverable. It needs to be heat-treated to relieve stresses or set mechanical properties, machined to final tolerances on critical features, surface-treated for corrosion protection, 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. Heat treatment, machining, surface treatment and assembly run on the same QA chain as the casting itself, with material certification 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.

CNC is rarely a standalone process. We combine it with casting, forming and finishing to deliver complete components — often in a single purchase order.
Metal casting as one link in a complete supply chain.
Most suppliers sell castings as raw shapes that someone else has to finish. We don't. At Pamatek, metal casting sits inside an integrated flow that runs from pattern design through casting and heat treatment 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, geometry and machining stock engineered together rather than negotiated after the first sample lands on a CNC bed.
