Trushape casts brackets, housings, weapon system and vehicle parts in 17-4PH, Inconel and 50+ alloys, with 100% inspection of critical parts, in-house NDT and EN 10204 3.1 records, for programmes across North America and Europe.
Trushape Precision Castings makes investment castings and precision castings for aerospace and defence: airframe brackets and structural fittings, housings and mounts for optical, radar and navigation systems, components for weapon, armament and missile systems, and rugged parts for military vehicles. We cast them in 17-4PH and 15-5PH, Inconel 718 and 625, cobalt alloys, high-strength steels such as 4340 and aluminium alloys such as A356, from 0.003 to 30 kg (0.1 oz to 66 lb) by investment casting and up to 90 kg (198 lb) by other processes.
We are an ISO 9001, ISO 14001, ISO 45001 and ISO 13485 certified foundry in Bhavnagar, India. Every critical part is 100% inspected, NDT is done in-house, and each shipment carries EN 10204 3.1 certificates and heat-number traceability. We do not hold AS9100, so we serve defence, MRO, sub-tier and qualification work under your quality plan, for buyers in the United States, Canada, Mexico, the United Kingdom and the European Union.
Follow one cast bracket through the six checks it passes before release. Chemistry, radiography, dye penetrant, ultrasonic testing and CMM measurement all happen in-house, and every result lands on one record.
The chemistry of every heat is checked on Spectromaxx and Bruker spectrometers against your grade, such as CB7Cu-1 for cast 17-4PH, and recorded against the heat number before the castings move on.
X-ray images show what the eye cannot: shrinkage, gas porosity or inclusions inside the wall. Critical sections are radiographed to the acceptance level on your drawing before machining begins.
Surface-breaking cracks and porosity would bleed through the white developer as clear indications. This surface shows none. Carbon and low-alloy steels are checked by magnetic particle instead.
Sound pulses travel through the heavier sections and flanges and echo back from any internal flaw, confirming soundness and wall thickness without cutting the part.
Critical dimensions are measured on a Zeiss CMM and Keyence VMM against your drawing and datums. Critical parts are inspected one by one, never sampled, and the deviation map goes into the report.
The part is released with its records: an EN 10204 3.1 material certificate, or 3.2 on request, NDT and dimensional reports, heat treatment records and heat-number traceability from melt to dispatch.
Four families of parts, each cast in the alloy its strength, weight and environment call for, and each backed by the same inspection and records.
Brackets, fittings and structural elements that need a high strength-to-weight ratio, cast in aluminium, 17-4PH and 15-5PH.
Brackets and fittingsComponents for firearms, armament and missile systems that demand exceptional durability and consistent performance, shot after shot.
Armament and missilesHousings and mounts for radar, sighting and navigation technology that must hold alignment through shock, heat and cold.
Housings and mountsRugged castings for military vehicles that withstand extreme conditions and rigorous, sustained use in the field.
Built for the fieldTurn this investment-cast vaned ring through a full revolution. Vanes, shroud and hub come out of one ceramic shell in a single pour: the kind of weld-free geometry that removes joints and saves weight on aerospace and defence hardware.
Vanes, shroud and hub are cast together, so there are no welds or fasteners to inspect, crack or loosen in service.
Thin, even walls come out of the ceramic shell close to final size, keeping weight down without extra machining.
Bores, faces and datums are finished to drawing on our CNC turning centres and 4-axis Makino VMCs.
Zeiss CMM reports, dye penetrant and radiography where specified confirm geometry and soundness, traceable to the heat.
Optical and sighting systems need housings that hold alignment through shock, heat and cold. Scroll or use Explode view to take this unit apart, and drag to turn it. Green markers show the parts we cast and machine.
The main cast housing in A356 or LM25 aluminium, with bosses, ribs and mounting faces cast in, then machined to drawing.
A cast cover with stiffening ribs, machined flat to seal the housing against dust and moisture.
A rail clamp or mounting base in 17-4PH or 4140 for a stiff, repeatable interface to the platform.
Cast and machined barrels that locate the optics on one common axis.

Equivalents are the closest common matches, shown for comparison. We cast to the ASTM, EN or customer specification on your drawing and verify the chemistry of every heat by spectrometer.
See all 50+ alloy gradesIn aerospace and defence, a casting is only as good as the evidence behind it. So every critical part leaves with its chemistry, its X-ray, its measurements and its heat number, on the record.
No outside labs in the loop for the checks that matter most. Results stay under one roof and on one record, ready for your incoming inspection and your customers' audits.
Every heat checked on Spectromaxx and Bruker spectrometers against your grade.
Mechanical properties tested to your material specification.
Internal soundness of critical sections, to the acceptance level you specify.
Internal flaws and wall thickness in heavier sections and flanges.

Solution treatment and ageing, quench and temper or stress relief in-house, then CNC machining to drawing.
100% inspection of critical parts, NDT, the documentation pack with EN 10204 3.1 certificates, export packing and dispatch.
We cast airframe brackets and structural fittings, housings and mounts for optical, radar and navigation systems, components for weapon, armament and missile systems, and rugged parts for military vehicles. Parts run from 0.003 to 30 kg (0.1 oz to 66 lb) by investment casting and up to 90 kg (198 lb) by other processes, supplied as-cast or machined ready to assemble.
No. Trushape is certified to ISO 9001:2015, ISO 14001:2015, ISO 45001:2018 and ISO 13485:2016, and does not currently hold AS9100, NADCAP, IATF 16949, PED or ASME approvals. Where a programme calls for them, we support MRO, aftermarket, sub-tier and prototype work to your drawing and inspection plan, and treat formal aerospace approval as a roadmap item.
ISO 13485 is the quality standard for medical devices, not an aerospace approval. It shows that our processes are validated, risk-managed and fully traceable, and that same discipline, with 100% inspection of critical parts, is applied to every aerospace and defence casting we make.
Precipitation-hardening stainless steels 17-4PH (CB7Cu-1) and 15-5PH (CB7Cu-2); nickel and cobalt alloys such as Inconel 718, Inconel 625, Hastelloy and Stellite 6; high-strength steels such as 4340, EN24 and 4140; stainless 316, 316L and duplex F51; and aluminium alloys such as A356, LM25 and 535. More than 50 grades are on file.
Every critical part is 100% inspected. In-house we run radiographic, ultrasonic, dye penetrant and magnetic particle testing, dimensional inspection on a Zeiss CMM and Keyence VMM, spectrometer chemistry on every heat, and tensile, hardness and impact tests to your specification.
Each shipment carries EN 10204 3.1 material certificates, or 3.2 when your order requires independent inspection, with NDT and dimensional reports, heat treatment records and heat-number traceability from melt to dispatch, so every part has one auditable record.
Yes. With 3D-printed patterns from our 3 FDM and 2 SLA printers we cast qualification samples and low volumes in 2 to 4 weeks, without hard tooling, then scale to series production with the same documented process once the part is approved.
Investment castings typically hold CT5 to CT7 to VDG P690, with D2 as our standard grade and ±0.20 mm (±0.008 in) as the tightest agreed tolerance on dimensions up to 6 mm. Tighter tolerances on critical features are reached by CNC machining and confirmed on a Zeiss CMM.
Yes. Solution treatment and age hardening, quench and temper and stress relief are done in our own furnaces, and 8 CNC machines, including 4-axis Makino VMCs, machine bores, faces and threads to drawing, so parts leave ready to assemble.
Yes. Trushape exports castings to Germany, the UK, Belgium, Denmark, Spain, Italy and other countries, and serves buyers across North America and Europe, including the United States, Canada and Mexico. Parts ship by sea or air freight with English documentation, and delivery terms are agreed per order.
For airframe brackets, housings and mounts we cast A356, LM25 and 535. A356 can be heat-treated for strength, and aluminium castings weigh about a third as much as steel, which makes them the usual choice for lightweight housings and structural parts.
India offers a deep foundry base, strong engineering talent and competitive cost, and gives North American and European buyers a proven second source outside China. Trushape adds an integrated plant, four ISO certifications, more than 24 years of casting experience and English documentation to make that switch low risk.
When a casting goes into a system people depend on, the proof matters as much as the part. Trushape casts, tests and documents aerospace and defence components for programmes across North America and Europe.
