Specialized Castings: Precision Solutions for Every Industry

National Solder Company (NASCO) provides high-quality specialized castings designed to meet exact engineering and manufacturing requirements. Used across aerospace, automotive, medical, energy, and industrial applications, our castings combine precision, strength, and reliability.

 

What Are Specialized Castings?

Specialized castings are components produced from metals, alloys, or other materials to meet specific physical, chemical, and mechanical properties. Created through casting—pouring molten material into a mold and allowing it to solidify—they allow for:

  • Complex shapes
  • Intricate details
  • Precise dimensions

These capabilities often cannot be achieved through other manufacturing processes, making specialized castings essential for high-performance applications.

 

Casting Processes We Use

Investment Casting:

  • Ideal for small, intricate parts with high dimensional accuracy.
  • Uses a wax or plastic pattern coated in a ceramic shell, then molten metal is poured in.

Sand Casting:

  • Suitable for large, complex parts.
  • Uses sand and binder molds; less dimensional precision but cost-effective for bigger components.

Material Options:

  • Aluminum & Magnesium Alloys – lightweight with excellent strength-to-weight ratio.
  • Steel & High-Strength Alloys – for exceptional durability in demanding applications.
