What to Look for in an Permanent Mold Casting Manufacturer

Permanent mold casting offers excellent repeatability, surface finish, and mechanical strength. Choosing the right supplier is key to achieving consistent, cost-effective results. Here's what to consider:

  • Material Capabilities – Aluminum, magnesium, brass, and bronze are commonly supported. Ensure the supplier can work with your required alloy.
  • Mold Design Expertise – In-house tooling and engineering ensures faster iteration, better mold longevity, and optimized part performance.
  • Precision & Repeatability – Look for manufacturers with proven dimensional accuracy and minimal porosity.
  • Production Volume Range – Permanent mold is ideal for medium to high-volume runs. Confirm the supplier’s ability to scale.
  • Secondary Operations – Machining, finishing, and assembly can reduce your lead times and simplify project management.
  • Certifications – ISO 9001, AS9100, or IATF 16949 demonstrate quality system standards.

Industries That Rely on Permanent Mold Casting

Permanent mold casting is used across sectors that need durable, dimensionally stable components:

  • Automotive – Transmission cases, brackets, wheels, and engine components.
  • Aerospace – Lightweight structural components and enclosures.
  • Marine – Corrosion-resistant parts such as housings, valves, and hardware.
  • Industrial Equipment – Precision parts for pumps, compressors, and machinery.
  • Consumer Products – Fixtures, furniture hardware, and sporting equipment.

What is Permanent Mold Casting?

Permanent mold casting is a metal casting process where molten metal is poured into reusable molds (typically made of steel or cast iron). Unlike sand casting, the mold doesn't break apart with each use, allowing for more consistent parts and tighter tolerances over longer production runs.

This method excels in producing parts with improved surface finish, mechanical properties, and dimensional stability. It's ideal for non-ferrous metals such as aluminum and magnesium alloys.

Frequently Asked Questions

Permanent mold casting uses gravity or low pressure to fill the mold, while die casting injects metal under high pressure. The latter allows for finer features but requires more expensive tooling.

Typical tolerances range from ±0.005 to ±0.015 inches per inch, depending on part geometry and material.

Yes, but it's generally better suited for simpler geometries compared to investment or die casting. Core inserts can help expand shape complexity.

It's most cost-effective at medium to high volumes due to the initial cost of tooling. However, long mold life balances the upfront investment.
