Metal Casting

While delivering prototypes for customer programs, we were repeatedly asked to provide low-volume metal casting service. To close that gap, ZigiTech built a qualified supplier network focused on real production control, not just price matching.

Large casting plants often decline smaller orders, while many small shops cannot keep up with strict quality and schedule targets. We treated this as a long-term capability build and developed partnerships that support overseas teams with stable execution.

Today, we deliver high-pressure die casting in aluminum, magnesium, and zinc, together with investment casting in brass and steel grades. As a machinery parts manufacturer and trusted metal processing company, we align technical review, quality checkpoints, and shipment planning under one Manufacturing Service workflow.

Why Choose ZigiTech for Metal Casting

It may seem unusual to work with a rapid manufacturing team for casting, but our integrated workflow gives you clear quality, schedule, and communication advantages.

We have built strong, audited relationships with partners for pressure die casting and investment casting programs.

Our in-house precision CNC capability supports efficient post-machining for tighter tolerances and cleaner final geometry.

With experienced project coordination, we keep information transfer clear and help customers hit punctual delivery targets.

What Is Pressure Die Casting?

Similar in concept to plastic injection molding, pressure die casting is a metal casting method where molten alloy is injected into a hardened die cavity under high pressure to produce repeatable parts. At ZigiTech, we use controlled die casting equipment and verified tooling workflows to form parts in aluminum, zinc, magnesium, copper-based alloys, and other selected materials.

This process is highly reliable for projects that need consistent quality with practical cost control. Based on part geometry and output planning, we support both pilot quantities and stable volume ramps, typically from tens of parts to larger production batches within our Manufacturing Service framework.

Pressure die casting parts with precise rib and fin details
  • Low unit cost per part when moving into larger production quantities
  • Excellent surface finish with stable dimensional repeatability
  • Complex geometries can be achieved with limited post-machining
  • Well suited for medium and larger metal parts that are expensive to machine

ZigiTech Die Casting Capabilities

Details
Tolerance High-precision die-cast parts usually require secondary machining to meet tight tolerances, with achievable accuracy down to +/-0.01 mm on selected features.
Minimum Wall Thickness For stable filling, aluminum alloys are typically designed at 1.5 mm and zinc alloys can go down to 0.8 mm in suitable geometries.
Wall Thickness Ratio A wall-thickness ratio within 1:3 is recommended to reduce uneven filling risk.
Hole Diameter In aluminum die casting, round holes below 3 mm generally need secondary drilling. Internal and external threads are typically finished through post-machining.
Draft Angle A minimum draft angle of 0.5 degrees is recommended to support reliable demolding.
Maximum Die Life (Cycles) Typical die life can reach about 1,000,000 cycles for zinc alloys, and around 100,000 cycles for magnesium and aluminum alloys.
MOQs Typical production planning starts from 500 to 1,000 pieces depending on die and process complexity.
Lead Time A common lead-time range is 20-25 days, depending on mold architecture and part structure complexity.

Metal Casting FAQ

Metal casting is often the better route for large parts, complex undercut features, and geometries that are inefficient to machine from solid stock. In many cases, casting provides the most practical balance of structure, cost, and manufacturability.
We combine a qualified partner network with practical tooling and pattern strategies to control cost at low quantities. This allows us to support prototype and bridge-volume orders without forcing customers into full-scale production spending too early.
Yes. We regularly combine casting with CNC post-machining for features such as threads, precision interfaces, engraving, and cosmetic refinement when required by your application.
For most programs, we can support orders from around 10 units, then scale output based on part complexity, alloy selection, and tooling strategy.
Verified Client Feedback
Trusted by teams shipping precision parts under real production deadlines.

This was one of those jobs where we mainly needed the supplier not to create extra work. In that respect, Zigitech did very well.

Chris Walters Engineering Director, US industrial automation integrator

We started with prototype parts and later rolled into a small production batch, so handoff between stages mattered. The process stayed orderly instead of feeling like two separate vendors.

Rebecca Stone Program Manager, US mobility hardware company

The aluminum housings on our order had flatness requirements that were not especially forgiving. Incoming checks looked good, and the assembly team did not send anything back.

Koen Visser Mechanical Engineer, Dutch industrial electronics supplier

During a medical cart subsystem review, their comments were specific enough to improve the drawing without sending us into another long design cycle.

Rachel Moore Product Engineer, UK healthcare equipment brand

We ordered welded frames and brackets, and the result felt dependable rather than flashy. Dimensions, finish, and packing all matched what had been agreed.

Diego Alvarez Supply Chain Manager, Spanish machinery integrator

Our first order was really a supplier test for recurring custom parts. Quote speed, document control, and part quality were all strong enough for us to keep going.

Maya Chen Global Commodity Lead, Singapore semiconductor equipment supplier

The tooling review on our plastic parts was useful because it focused on the real trouble spots. We changed rib design and gate location before spending money in the wrong direction.

Dominic Fraser Mechanical Lead, Canadian smart home brand

We bought stainless and brass components for calibration fixtures, and the parts were separated and labeled well enough that our receiving team had no questions.

Aisha Rahman NPI Manager, UAE instrumentation company
