10 Questions to Ask Before Choosing an Automotive Die Manufacturer in India
Selecting the wrong automotive die manufacturer can lead to missed SOP dates, repeated tryout failures, production scrap, and dimensional quality issues. The best supplier is chosen not by comparing quotations alone, but by asking the right technical and operational questions.
Question 1 — Do You Use AutoForm Simulation on Every Programme?
A capable supplier should use AutoForm simulation from the feasibility stage through the complete forming sequence, including springback compensation and process validation.
Question 2 — What Is Your 5-Axis Machining Capability?
Ask for machine make, model, bed size, and positioning accuracy. Large transfer dies require true 5-axis simultaneous machining to achieve the required die face accuracy.
Question 3 — Do You Have In-House Tryout Presses?
Suppliers with 800T–1,600T in-house tryout presses can complete correction cycles much faster than suppliers dependent on third-party facilities.
Question 4 — What Experience Do You Have With My Material Grade?
Request references for programmes using the same material grade, especially for AHSS applications where springback and tooling requirements differ significantly from mild steel.
Question 5 — What Inspection Equipment Do You Have?
A supplier should have an adequately sized CMM with traceable calibration and ideally a 3D scanning system for complete surface inspection.
Question 6 — Can You Provide a Detailed Programme Schedule?
A structured schedule with milestone dates demonstrates project management maturity and improves on-time programme delivery.
Question 7 — What Does Your DFM Review Include?
An effective DFM review should include feasibility simulation, blank development, springback analysis, flange assessment, and forming sequence recommendations before die design begins.
Question 8 — What PPAP Level Can You Support?
Look for suppliers capable of Level 3 PPAP including Design FMEA, Process FMEA, control plans, Cpk studies, MSA, and production sample documentation.
Question 9 — What Is Delivered With the Die?
The delivery package should include CMM reports, AutoForm reports, tryout documentation, maintenance schedules, process parameters, and recommended spare parts.
Question 10 — Can You Provide OEM or Tier-1 References?
Ask for named customer references, comparable programme examples, and site visit opportunities. Proven capability is always more valuable than marketing claims.
Why These Questions Matter
Choosing a supplier without validating these capabilities often results in additional tryout cycles, engineering changes, production delays, and significantly higher programme costs than the apparent saving on the original quotation.
FAQs
How long should a supplier qualification audit take? A complete supplier audit generally requires a full day on-site plus one to two weeks for documentation and reference verification.
Should I visit the supplier before awarding a programme? Yes. For new suppliers and complex AHSS programmes, verifying machinery, tryout capability, inspection equipment, and production facilities in person is strongly recommended.
What are the biggest supplier red flags? Missing simulation reports, no 5-axis machining, inadequate tryout capacity, poor inspection capability, missing customer references, and unrealistically low quotations are all warning signs.
