Investment Casting

Investment Casting Services, We take pride in being a leading sourcing company in India, specializing in providing top-notch investment casting solutions that cater to a wide array of industries. With a commitment to excellence and a focus on precision, we have gained a reputation for delivering high-quality products tailored to your unique requirements.

Investment casting, also known as lost-wax casting, is a highly versatile and precise metal forming process. It is ideal for crafting complex and intricate parts with fine details that are difficult to achieve through other manufacturing methods. This method offers exceptional flexibility in materials, from ferrous metals like stainless steel and carbon steel to non-ferrous alloys like aluminium and brass. The investment casting process ensures excellent surface finish, close tolerances, and minimal post-processing, reducing production time and costs.

we have honed our investment casting expertise over the years, making us a trusted partner for clients worldwide. Our experienced team, state-of-the-art facilities, and advanced technology allow us to deliver superior castings for diverse applications, including aerospace, automotive, medical, and more. We take pride in offering a comprehensive range of investment casting services, from initial design assistance to rapid prototyping and production, ensuring that you receive precisely what you need.

Quality is at the core of our investment casting services. We have stringent quality control measures in place at every stage of production. Our skilled technicians and engineers work diligently to ensure that each component meets or exceeds your specifications. Zastata is ISO-certified, demonstrating our commitment to maintaining the highest industry standards.

In Investment Casting, different materials can be used. The kind of material used to generate the casting mainly depends on its application of utilization. Zastata works with variety of material grades, few of them are,


It is one of the best alternatives in many casting procedures due to its properties such as, Corrosion resistance, high thermal and electrical conductivity, mechanical properties, durability at elevated temperatures, etc.


Steel castings from investment casting usually have layer of chromium oxide which provides high durability. It is also used for its high corrosion resistance, more strength and toughness.

Metal Alloys

Investment casting commonly employs copper-based alloys (brass, bronze, beryllium-copper) known for corrosion resistance and wear resistance, along with nickel and cobalt-based alloys.

Cast Iron

They have high strength, heat resistance and toughness. Suitable for more complex structures that steel which is the reason for its high production cost compared to steel.

Zastata works in variety of other Iron grades like

  • Gray Iron Grades [HT150, HT200, HT250, HT300, HT350]
  • Ductile Iron Grades [QT400-15, QT400-15, QT400-15, QT450-10, QT500-7, QT500-9]

Some of the Heat treatment processes Zastata provides to enhance material properties and support fully finished product are,

  • Normalizing
  • Annealing
  • Quenching
  • Tempering
  • Carburizing treatment process.

Zastata also performs premium quality testing procedures such as Non-destructive testing like fluorescent penetration, magnetic particle, radiographic, or other inspections may also be performed. Final dimensional inspections, alloy test results, and NDT are validated authentically with expertise prior to shipment.

Zastata provides some finishing Processes like,

  • Polishing, Sanding, Deburring, Grinding, etc.
  • Peening & shot blasting – to roughen a smooth surface is required.
  • Fettling – to improve surface flatness of the component.
  • Painting and Powder coating – to enhance physical wear resistance, prevents corrosion and also improve physical appearances.

Zastata has good understanding and experience with Quality documentation like:

APQP – Advanced Product Quality Planning
FMEA – Failure Mode Effective Analysis
PPAP Level 3 – Production Part Approval Process
SPC – Statistical Process Control
MSA – Measurement System Analysis

Zastata chooses manufacturers based on required certifications and product applications. Our manufacturers are certified to:

  • ISO 9001:2015 (Quality Management System)
  • ISO 14001:2015 (Environmental Management System)
  • ISO 45001:2018 (OH & SMS)
  • AS9100 Rev C (Aviation, Space and Defence)
  • ISO13485:2016 (Medical Devices)
  • IATF16949:2016 (Automotive Quality Management System)

Other Types of Casting

Whilst Pressure die casting is a widely used casting method for high-volume production, there are other casting methods that have their merits
