Precision investment castings engineered to international standards
At Vimax Technocast, precision investment casting begins with two fundamental questions:
- 1. Is the part the right size (dimensional tolerance)
- 2. Is the part the right shape (geometric tolerance)
As one of the leading precision investment casting manufacturers in India, Vimax Technocast delivers high-precision investment castings through a repeatable manufacturing system that combines advanced software, controlled casting processes, CNC machining, and rigorous inspection. This enables us to consistently meet VDG P690 D2, IS 11166 Class 2, and ISO 1101 and ISO 8062-3 requirements.
It is this emphasis on delivering precision castings continually that has made us trusted partners to global OEMs and tier-1 suppliers. We export precision investment castings to OEMs across the US, Canada, the UK, France, Spain, Italy, South Africa, and other leading global markets.
Our Precision Investment Casting Methodology
Producing accurate castings consistently and at scale requires an unwavering focus on every detail. At Vimax - an ISO 9001-certified foundry, we focus on every detail to deliver repeatable precision at scale.
Simulation
Detailed 3D design, gating, metal flow, temperature distribution, cold shuts, misruns, and hot spot replication digitally using AnyCasting
Tooling development
Designing core tooling and multicavity aluminum dies to establish shrinkage, machining allowance, and wax pattern accuracy using CAD-CAM software.
Prototyping
Producing 5-10 articles to verify die and wax pattern accuracy. We use rapid prototyping to iterate quickly and compress timelines without loss of precision.
Inspection
Validating the article against customer specifications and industry standards. We use spectrometers, coordinate measuring, and universal testing machines. Our team also runs NDT, ultrasonic, and magnetic particle tests.
First article inspection
Verifying the initial articles produced for characteristics, establishing physical proof of compliance and precision, and highlighting part number accountability. This report is then shared with the customer for final sign-off.
Accurate patterns creation
Automated and semi-automated lines to ensure repeatable negative shapes.
Even-bodies cast creation
Using rainfall sanders to provide even ceramic and stucco coats to ensure uniform thickness and precise internal geometry. This step is essential for achieving repeatable precision investment castings.
Controlled pouring
Precisely controlled pouring minimizes turbulence, shrinkage, hotspots, air entrapment, cold shuts, and oxide formation to maintain casting accuracy.
Machining
CAM-based CNC machining refines surface finish, dimensional tolerances, and geometric accuracy to achieve high precision investment castings.

Our Investment Casting Process at a Glance
Our engineered precision investment casting process and expertise with a diverse range of materials enable us to deliver repeatable, high-precision investment castings in India and globally. The following is a chronology of how components form and move through the production process.
| Process Stage | Key Features |
|---|---|
| Tooling & Wax pattern | Precise dies for repeatable, accurate wax patterns at scale. |
| Investing & Heating | Creating ceramic casts and heating them to melt the wax and obtain exact cavities. |
| Pouring & Fettling | Gentle pouring for controlled cooling and gradual solidification, followed by knocking, gate removal, and preliminary grinding. |
| Heating & Machining | Redistributing grains to increase strength; machining to improve surface finish on the body and mating surfaces. |
| Final Inspection & Shipping | X-ray, dye penetrant, and radiographic tests to prove component integrity, followed by packaging and shipping. |

FAQs
What surface roughness and tolerances does Vimax deliver as a precision casting manufacturer in India?
As precision investment casting manufacturers in India, we deliver tolerances in the range of DCTG 4-7, GCTG 3-6, and VDG P690 D2. Our finished castings have surface roughness between N7-N9.
What makes investment casting suited to precision output?
Investment casting is ideally suited for producing intricate geometries with tight tolerances, excellent dimensional accuracy, and superior surface finish. Curves, radial corners, and uncommon shapes are infinitely easier to produce because molten metal occupies empty spaces in a cast and then solidifies to take shape.
What are the key challenges in precision investment casting?
Key challenges in precision investment casting are: design complexity, material suitability, non-availability of a trained workforce, process consistency, and un-tuned measuring equipment.
How to verify if a manufacturer can deliver precision investment castings?
When evaluating a precision investment casting manufacturer, review their casting methodology, inspection capabilities, tolerance standards, software, first article inspection (FAI) process, and previous production experience. A manufacturer that cannot clearly demonstrate these capabilities may not be the right choice for high-precision applications.
