Your Drawing. Your Specification. Our Forge.
Custom forging development is not complicated if the supplier has the right in-house capability and a structured process. At Shivam Forge, we handle the complete journey from your CAD file or 2D drawing to a production-approved forged component — die design, die manufacture, forging trials, first article inspection, capability study and PPAP. You deal with one team, not a chain of subcontractors.
Custom Forging Development Process
Step 1 – DFM Review
When you submit a drawing (PDF, DXF, STEP, IGES or SolidWorks), our engineering team conducts a Design for Manufacturing (DFM) review before quoting. We check draft angles (minimum 3–7° for steel forgings), parting line feasibility, minimum wall thickness, die fill risk zones, and grain flow alignment with the part's principal stress direction. DFM comments are shared in writing with sketch references within 48 hours.
Step 2 – Die Design
Our in-house die design team produces die drawings using CAD tools. Die cavities are designed with appropriate forging allowances per IS 3469 / DIN 7526, flash land and gutter geometry matched to the press/hammer to be used, and shrink factor applied for the material's thermal contraction. Die design drawings are shared with the customer for reference before manufacture commences.
Step 3 – Die Manufacture
Dies are machined from H13 hot work tool steel (hardened to 44–48 HRC) on our in-house CNC machining centres. Die sinking, EDM for complex profiles, and die bench fitting are done at our Rajkot tool room. Die manufacture lead time is typically 2–4 weeks depending on cavity complexity. Die life is estimated at quotation and die ownership terms confirmed in the commercial order.
Step 4 – Forging Trials & First Samples
Trial forgings are produced on the selected press or hammer line with the new die set. The first 10–20 pieces are subject to 100% dimensional inspection against the drawing, hardness check and visual examination for fill, flash distribution and surface quality. Adjustments to die relief or forging parameters are made at this stage before final sample submission.
Step 5 – First Article Inspection & Customer Approval
A formal First Article Inspection Report (FAIR) is prepared covering all drawing characteristics with balloon reference numbers, measured values and acceptance status. The FAIR is submitted with material test certificate, heat treatment record, and capability data (Cpk ≥ 1.33 on critical dimensions). Customer written approval is obtained before production commences.
Step 6 – Production Supply
After approval, production orders are scheduled and managed against the approved control plan. First-off inspection is repeated at the start of each production run. Deviations from approved parameters trigger a deviation notification and customer approval before continued supply. Production samples can be archived at agreed intervals for reference.
Custom Forging Capabilities & Materials
Accepted File Formats
We accept PDF (2D drawing), DXF (2D CAD), STEP (.stp / .step), IGES (.igs / .ige) and SolidWorks (.sldprt) files for 3D solid model quotation and die design. For hand sketches or legacy paper drawings, we accept scanned copies and will reproduce a CAD drawing for DFM review confirmation before proceeding.
Material Selection Assistance
If your drawing specifies a function (tensile strength, hardness, operating temperature, corrosion environment) rather than a specific material grade, we provide material selection recommendations with cost comparison. Common selections: EN8 for general duty carbon steel, EN24 / SAE 4340 for high-strength, 42CrMo4 for fatigue and torsion, 20MnCr5 for case-hardened gears, stainless 410 / 304 for corrosive service.
Cost Engineering & Weight Optimisation
Our DFM team identifies opportunities to reduce part weight (and therefore billet cost) while maintaining functional performance. Rib placement, section reduction and parting line repositioning can reduce billet weight by 10–30% on first-generation die designs — valuable when forgings are to be produced in quantities above 5000 pieces annually.
Prototype to Production Scaling
Development samples (3–50 pieces) are supplied with the same die and process that will be used for production — not prototype tooling that gets scrapped and rebuilt. This means the samples are genuinely representative of production quality and capability data from samples is valid for PPAP submission.
Custom Heat Treatment Specifications
We develop and validate heat treatment cycles for custom parts specifying unusual hardness bands or property combinations. If your drawing requires 340–380 BHN core hardness in EN24 with a specific impact toughness floor (e.g., 40 J Charpy at -20°C), we run qualification heat treatment batches and confirm properties before committing to the production cycle.
Die Ownership, Maintenance & Storage
Die ownership (customer or Shivam Forge) is agreed in the commercial order. Customer-owned dies are stored in our tool store at no charge during active programs and returned to customer on request. We carry out periodic die maintenance (re-hardening of worn cavities, repair of edge chipping) and track die shot count against expected life to forecast replacement timing.
Custom Forging for OEM & Export Programs
OEM Custom Forging Supply
We develop and produce custom forgings for OEM assembly lines in the automotive, tractor, agricultural machinery, hydraulic, oil and gas, and general engineering sectors. Proprietary part numbers are treated confidentially under NDA. We do not cross-supply the same drawing to competitors or list your part numbers in our product catalogue.
Export Custom Forging Capability
Custom forgings for export buyers in Germany, UAE, USA, UK and Australia are supplied with EN 10204 Type 3.1 material certificates, full dimensional FAIR, first sample approval documentation, and sea-worthy packaging. We have experience with customer-specific approval forms from European engineering groups and adapt our documentation to their format.
Bespoke Alloy & Grade Specifications
We forge to proprietary OEM material specifications beyond standard IS, EN or SAE grades. If your specification references an internal code (e.g., 'Grade X per ABC-MSPEC-0012'), we request the full chemical and mechanical requirements table and source billets to match from our network of approved Indian and imported billet suppliers.
NDA & IP Protection
Non-Disclosure Agreements are executed before we receive any proprietary drawings, specifications or project details. Our standard NDA is bilateral, covers all technical information shared, and has a minimum 5-year confidentiality term. We can also sign a customer's own NDA form. NDA execution is completed within 48 hours of request.
Small Batch & Short-Run Custom Forging
Not every custom part is a high-volume program. We supply short-run custom forgings (50–500 pieces) for replacement parts, spares programs, special machinery builds and research projects. For these programs, we may recommend open-die or near-net forging approaches where closed-die tooling investment is not justified by the volume.
Reverse Engineering from Physical Sample
When a drawing is not available but a physical sample component exists, we offer reverse engineering — 3D scanning, CAD model generation, DFM review, and die design from the scan data. This is particularly useful for obsolete parts, imported component replacement, or end-of-life tooling replacement for running machinery.
Shivam Forge has been manufacturing custom forged components to OEM drawings for over 20 years, operating from our ISO 9001:2015 certified facility at Shapar, Rajkot, Gujarat. Custom forging development is a structured engineering process at Shivam Forge — not an informal arrangement where a sample eventually appears weeks after the expected date with no accompanying documentation. Every custom forging program follows a defined sequence: DFM review, die design, die manufacture, forging trials, FAIR, capability study and production approval.
Our die design and manufacture capability is entirely in-house. Dies are machined from H13 hot work tool steel on CNC machining centres, with EDM available for complex cavity features. Die manufacture lead time of 2–4 weeks is achievable because we do not depend on external die shops with their own queues. When a die needs modification after the first trial — a common requirement in development — we turn the change around in days, not weeks.
For customers submitting their first custom forging inquiry, the process is straightforward. Send us your drawing in any standard format (PDF, DXF, STEP, IGES or SolidWorks), a material grade or functional requirement, the quantity range and any delivery constraint. We will respond within 24–48 hours with a DFM review and a detailed quotation covering unit price per quantity break, tooling cost, sample lead time and production lead time. There is no obligation at the quotation stage, and we sign an NDA before you share the drawing if your design is proprietary.
We manufacture custom forgings in carbon steel (EN8, EN9, C45, IS 2062), alloy steel (EN24, SAE 4140, 42CrMo4, EN19, SAE 4340, 20MnCr5, EN36), stainless steel and on request other grades to customer specification. Post-forging services including heat treatment, CNC machining and third-party NDT are available to supply a finished component, not just a raw forging. Material test certificates are supplied as standard; EN 10204 Type 3.1 certificates are available for export and critical applications.
Custom forging programs that start with development quantities of 50–200 pieces and grow to annual volumes of 20,000–100,000 pieces are exactly the kind of relationship Shivam Forge builds. We invest in getting the development right — proper tooling, proper first article process, proper capability data — because that investment protects both parties once production volumes build.

Frequently Asked Questions
What file formats do you accept for custom forging quotations?
We accept PDF (2D drawing), DXF, STEP (.stp/.step), IGES (.igs/.ige) and SolidWorks (.sldprt) files. Scanned paper drawings are also accepted. For 3D CAD files, we prefer STEP format as it is neutral and compatible with our die design software.
What is the die manufacture lead time for a new custom forging?
Die manufacture lead time is typically 2–4 weeks from order placement and drawing approval, depending on die complexity. A simple round or block die takes 2 weeks. A complex multi-cavity impression die with EDM features takes 3–4 weeks. We confirm the specific timeline in our quotation.
How many pieces can I get as first samples before committing to production?
Typically 5–20 pieces for the first sample run. We use the same die and process that will be used for production — not cheap prototype tooling. This means first samples are genuinely representative of production quality and the FAIR data is valid for PPAP.
Do you sign NDAs before receiving custom forging drawings?
Yes, always. We execute a bilateral NDA before receiving any proprietary drawings, specifications or project information. We can use our standard NDA form or sign the customer's own form. NDA completion is typically within 48 hours.
Can you help optimise a design for forging manufacturability?
Yes. Our DFM review identifies issues with draft angles, wall thickness, parting line placement and die fill risk before quoting. We also offer weight optimisation recommendations that can reduce billet cost by 10–30% on initial designs. DFM comments are provided in writing within 48 hours of receiving the drawing.
What is the minimum quantity for a custom forging order?
Development quantities of 5–50 pieces are available for first article and validation. Production minimum order quantities depend on part size: approximately 500 pieces for medium components (1–20 kg) and 2000 pieces for small components (under 1 kg). Short-run programs (50–500 pieces total) are accommodated where tooling economics allow.
Do you own the dies or does the customer?
Die ownership is agreed commercially at the time of quotation and confirmed in the purchase order. Customer-funded tooling remains customer property, stored at Shivam Forge at no charge during the active program. Shivam Forge-funded tooling remains our property but is dedicated to the customer's program for the agreed term.
Can you forge to a proprietary material specification rather than a standard grade?
Yes. Provide the full chemical composition limits and mechanical property requirements from your material specification, and we will source billets from approved suppliers who can certify to those parameters. We have done this for European automotive OEM specifications that reference internal grade codes not found in IS or DIN standards.
