A structured, transparent manufacturing process is what separates reliable suppliers from the rest. At Audhe Industries, every aluminium casting, CNC machined component, iron casting and fabricated part follows a defined, ISO 9001:2015 controlled process — from your first enquiry to final delivery.
Enquiry, Drawing Review & Design for Manufacturability
Enquiry & Engineering Review
Every project at Audhe Industries begins with a thorough engineering review. When you submit your drawing, 3D model or sample, our engineers perform a Design for Manufacturability (DFM) analysis — evaluating wall thickness, draft angles, parting lines, gate locations, machining datums and tolerance stack-up before any tooling investment is made.
This proactive review catches design issues early, reduces tooling rework and ensures the most cost-efficient manufacturing route is selected — whether aluminium gravity die casting, pressure die casting, investment casting, iron casting or CNC machining from billet.
Written analysis of casting/machining feasibility with recommended design changes before tooling
Gravity die, pressure die, investment casting, sand casting or CNC — we select the optimal method
Detailed cost breakdown covering tooling, piece price, surface treatment and packaging
DFM report and quotation signed off by customer before any production activity begins
Incoming Material Control
Once the order is confirmed, raw materials are selected and approved before a single kilogram enters the foundry or machine shop. All aluminium alloys (LM2, LM4, LM6, LM24, LM25), grey and ductile iron grades, stainless steel, nickel alloys and engineering plastics are verified by optical emission spectrometer (OES) for exact chemical composition.
Only materials that pass our incoming inspection — including visual checks, dimensional verification of bar/ingot stock and spectrometer analysis — are released to production. Non-conforming materials are quarantined and returned to the supplier.
Chemical composition confirmed for every incoming batch of aluminium, iron and special alloys
Supplier MTCs reviewed and filed for full traceability — especially for stainless, nickel and titanium
Verified against customer drawing callout and our approved material supplier list
Red-tagged holding area for rejected materials — no risk of non-conforming material entering production
Material Selection, OES Verification & Incoming Approval
In-House Tool & Die Making, Mould Development
Toolroom & Die Making
Our in-house toolroom is one of our strongest competitive advantages. Rather than outsourcing mould and die manufacture, we design and machine all gravity die casting dies, pressure die casting dies, sand casting patterns, CNC fixtures and investment casting wax patterns ourselves — using high-grade H13 and P20 tool steels, EDM (Electrical Discharge Machining) and high-speed CNC milling.
This gives us direct control over tool quality, lead time and cost — and allows us to make engineering changes quickly without external delays. Export-quality moulds are also supplied to international clients on request.
High-speed CNC machining of die cavities and cores from H13, P20 and D2 tool steels
Complex cavity profiles and fine detail features machined by wire and sinker EDM
First articles produced from new tools and measured against drawing before production approval
Scheduled preventive maintenance on all production dies — ensuring long tool life and consistent casting quality
Production — Casting & Precision Machining
With approved tooling in place and materials verified, production begins. Our foundry and machine shop operate in close coordination — castings move directly from the foundry to CNC machining when required, eliminating unnecessary handling and delay.
Our production capabilities span aluminium gravity die casting, aluminium pressure die casting, green sand and shell mould iron casting, investment die casting, multi-axis CNC turning and milling, metal fabrication and industrial plastic components.
Gravity die, sand and pressure die casting of LM2–LM25 alloys in batch sizes from 50 to 50,000 pieces
Green sand and shell mould casting for grey iron (FG) and ductile iron (SG) components
Multi-axis turning, milling, boring and drilling to ±0.01mm on aluminium, steel and stainless

Casting, CNC Machining, Fabrication & Industrial Plastics
Shot Blasting, Painting, Anodising, Heat Treatment & Surface Finishing
Post-Processing & Surface Treatment
After casting and machining, components undergo customer-specified post-processing to achieve the required surface condition, corrosion protection or mechanical properties. Audhe Industries offers a complete range of surface finishing and post-processing services — either in-house or through certified partner facilities.
Steel shot and grit blasting to clean castings, remove scale, and prepare for painting or coating
Liquid painting and epoxy powder coating to specified RAL colours and film thickness
Hard and decorative anodising for aluminium components requiring corrosion or wear resistance
T6 solution treatment and ageing for LM25 aluminium castings; annealing for iron and steel parts
Zinc plating, nickel plating and chrome treatment available through certified plating partners
Vacuum impregnation sealing of porous aluminium castings used in hydraulic and pressure applications
Final Inspection & QC Documentation
Every component undergoes 100% final inspection before it is approved for packing. Our quality lab uses CMM (Co-ordinate Measuring Machine), surface roughness testers, hardness testers, OES spectrometer, precision gauges and visual inspection — all against the customer's approved engineering drawing.
Rejected components are segregated immediately, root cause identified and corrective action documented. No non-conforming parts leave our facility.
Critical dimensions verified against drawing using touch-probe CMM for complex casting and machined parts
Contact profilometer measures Ra/Rz on machined surfaces against drawing surface finish callouts
Brinell (castings) and Rockwell (machined steel) hardness testing with calibrated equipment
Inspection report, COC, spectrometer report and PPAP (on request) prepared for every shipment
100% Dimensional, Surface & Material Inspection Before Dispatch
Export Packing, Documentation & On-Time Dispatch
Packing, Export Documentation & Delivery
The final stage — and the one our clients see most directly. Approved components are packed to export standards, with full documentation prepared for domestic delivery across India or international shipment to clients in the USA, Europe, Middle East, Asia and Africa.
Each shipment includes: part-by-part identification, protective packing (corrugated, foam, VCI film for ferrous parts), palletisation and a complete export document set — ensuring components arrive in perfect condition and clear customs without delay.
Individual part wrapping, custom foam inserts, corrugated boxes and palletised loading for sea/air freight
Volatile Corrosion Inhibitor (VCI) film and papers protect ferrous castings during long transit periods
Commercial invoice, packing list, Certificate of Origin (COO), COC, material certificates — all prepared in-house
99% on-time delivery rate sustained over 12 months — tracked and managed by your dedicated account manager

1–6 WeeksOur capacity and track record in on-time delivery make us a reliable supply partner for Indian and international clients across multiple industries.
Our manufacturing process is designed to deliver more than just a component — it delivers confidence. Here is why procurement managers, engineers and buyers across 30+ countries trust Audhe Industries.
We make our own dies and moulds. No outsourcing, no toolmaker delays — faster turnaround, direct control over quality and easier engineering changes when needed.
Our DFM analysis catches design issues before a single cut is made on the die. Clients save money on tooling modifications and avoid production delays caused by design issues found after first article.
Castings move directly from foundry to CNC machining within our facility — no external logistics, no risk of damage in transit between suppliers, and tighter dimensional control from raw casting to finished part.
Quality is not a final inspection — it is built into our process at every stage. ISO 9001:2015 certified with documented control plans, process FMEAs and regular internal audits ensuring sustained performance.
Our export team handles all paperwork — commercial invoice, packing list, COO, COC, PPAP and material certificates. Clients in the USA, Europe and Middle East receive shipments that clear customs first time.
Every client has a dedicated account manager who tracks their orders from enquiry to delivery. No chasing multiple contacts, no lost emails — clear communication and accountability at every stage.
