High-Precision Investment Castings by Shubh Mangal Technocast
In the modern world of manufacturing, accuracy, consistency, and durability are not optional—they are essential. When it comes to producing intricate metal components with tight tolerances, high-precision investment castings are the gold standard. At Shubh Mangal Technocast, we specialize in delivering world-class investment castings tailored for industries that demand absolute precision—automotive, oil & gas, medical, pump, valve, and industrial machinery sectors.
As one of the leading investment casting manufacturers in India, we combine advanced lost wax casting techniques with the latest technologies in metallurgy, tooling, and quality control to ensure that every component exceeds client expectations.
What Are High-Precision Investment Castings?
Investment casting, also known as the lost wax casting process, is a manufacturing technique used to create complex metal components with exceptional dimensional accuracy and superior surface finish. The process involves creating a wax pattern of the desired part, coating it with ceramic material to form a mold, and then pouring molten metal into that mold to produce the final part.
At Shubh Mangal Technocast, our high-precision investment castings offer:
- Dimensional accuracy up to ±0.05 mm
- Complex geometries with undercuts, holes, and thin walls
- Excellent surface finish (Ra 3.2–6.3 µm)
- Near-net shape production minimizing machining
- Consistent quality across large production batches
Applications of Investment Casting
Our precision investment castings are used in a wide variety of sectors where tolerance, material integrity, and surface quality are critical. Some of the major industries we serve include:
- Automotive
We manufacture high-precision components such as gear levers, brackets, exhaust parts, turbo housings, and engine parts that require mechanical strength, fatigue resistance, and thermal stability. - Oil & Gas
In high-pressure and corrosive environments, our investment castings are used for valve bodies, connectors, actuators, and impellers—crafted from corrosion-resistant alloys and designed for extreme durability. - Pumps & Valves
Our castings are ideal for pump impellers, casings, valve stems, and flow control components where hydraulic efficiency and mechanical strength are vital. - Medical Equipment
We supply stainless steel and biocompatible investment castings for surgical tools, diagnostic instruments, and orthopedic implants with ultra-fine details and smooth finishes. - General Engineering
For industrial machinery, textile machines, and process equipment, we supply housing covers, arms, yoke assemblies, and brackets—cast with tight tolerances and high repeatability.

Our Lost Wax Casting Process: Step-by-Step
At Shubh Mangal Technocast, we follow a refined lost wax casting process to ensure high-precision results:
- Pattern Making
Wax replicas of the final part are created using aluminum dies and injection molding. These patterns maintain exact dimensional control and surface smoothness. - Assembly
Multiple wax patterns are joined to a central sprue system to form a “tree” for batch casting. - Shell Building
The wax assembly is dipped in a ceramic slurry and coated with refractory sand multiple times to build a robust shell around the patterns. - Dewaxing
The wax is removed from the ceramic shell using steam autoclaves, leaving behind a cavity in the shape of the component. - Firing
The shell is then fired at high temperatures (around 1000°C) to strengthen the mold and remove any remaining wax residues. - Pouring
Molten metal is poured into the preheated mold cavity under vacuum or gravity to ensure full fill and structural consistency. - Knockout & Finishing
Once cooled, the shell is broken, and the individual castings are removed, cut, ground, and finished. - Inspection & Testing
All parts undergo dimensional, mechanical, and NDT testing to ensure they meet specifications.
Materials We Work With
We cast a wide range of metals and alloys to meet diverse industrial requirements:
- Stainless Steel (SS 304, SS 316, SS 310)
- Alloy Steel
- Carbon Steel
- Nickel-Based Alloys (Inconel, Hastelloy)
- Duplex & Super Duplex Steel
- Copper & Bronze Alloys
- Customized Nickel-Iron-Chromium Compositions
Quality Control & Certifications
At Shubh Mangal Technocast, quality is the backbone of everything we do. Our rigorous quality assurance systems include:
- 100% dimensional inspection using CMM and gauges
- Mechanical testing (tensile, impact, hardness)
- Chemical analysis using spectrometry
- Non-destructive testing (RT, UT, MPI, LPT)
- Visual & pressure testing
- Documentation for full material traceability
We manufacture investment castings in compliance with international standards such as ASTM, DIN, BS, and ISO.
Why High-Precision Matters
For industries like aerospace, medical, and defense, even the slightest deviation in dimensions can result in catastrophic failure. That’s why high-precision investment castings are the go-to solution when quality, accuracy, and repeatability are non-negotiable.
Using high-precision castings:
- Reduces machining time and costs
- Increases reliability and service life of components
- Ensures compatibility with tight assembly tolerances
- Boosts overall product performance and safety

Advanced Tooling and CAD/CAM Integration
At Shubh Mangal Technocast, we understand that the precision of an investment casting is only as good as the tooling behind it. That’s why we use advanced CAD/CAM software to design and simulate tooling layouts before physical production begins. Our in-house tooling department uses CNC-controlled machines to create high-accuracy dies, jigs, and fixtures that ensure repeatability for every wax pattern produced.
This integration between digital design and physical manufacturing reduces errors, shortens lead times, and allows us to accommodate last-minute design changes without compromising on quality. Our engineers work closely with OEM clients during the design stage to optimize component geometry for better castability, strength, and material efficiency.
Custom Solutions for Complex Geometries
Not all castings are created equal. Some components—especially those used in aerospace, defense, or medical devices—require tight tolerances, internal passages, undercuts, or lightweight structural integrity. At Shubh Mangal Technocast, we thrive on complexity.
Our experience with intricate shapes and advanced alloys allows us to take on projects others cannot. Whether it’s a turbine blade with cooling holes, a surgical clamp with thin walls, or a precision fuel injector housing, we deliver castings that meet and exceed your application requirements.
Sustainability and Cost Efficiency
Investment casting is not only precise—it’s also sustainable and cost-effective. Since the process produces near-net-shape parts, there is minimal material wastage compared to machining from solid billets. Furthermore, components often require little to no secondary machining, reducing both production time and energy consumption.
Shubh Mangal Technocast is committed to eco-conscious manufacturing. We optimize our melting processes to reduce energy usage, recycle wax and shell materials where feasible, and maintain emission control systems throughout our foundry.
Whether you’re designing a new component or scaling up production, Shubh Mangal Technocast is your trusted partner for precision investment castings in India. Our engineering expertise, end-to-end service, and consistent quality make us the preferred choice for global clients.
