Manufacturing Services
From Drawing to Dispatch —One Source
Industrial Knives operates the design office, tool-room, heat treatment, surface coating and quality lab under one roof. 18 years of industrial-blade manufacturing since 2008, one engineering team end-to-end.
Looking for a blade manufacturer who can take a worn sample and ship a re-engineered part within weeks —not months? Most job shops will ask you to redraw it. We measure, reverse-engineer and, in many cases, improve on the original edge geometry. If you need ISO 9001 certified production with documented PPAP and a 5-dimension Quality Gate, you are in the right place.
- —18 years manufacturing blades since 2008
- —98% on-time delivery · 10,000+ custom blades shipped per year
- —Cpk ≥ 1.33 on critical dimensions, audited quarterly
Comparison
Industrial Knives vs Typical Job Shop
How Industrial Knives compares to a typical CNC job shop or overseas OEM. Compared with the alternatives, the difference is in-house control of every critical step —from steel sourcing to final QA documentation.
| Capability | Industrial Knives | Typical Job Shop |
|---|---|---|
| Design office in-house | ✓ 3D CAD + FEA on request | ✗ Outsourced |
| Vacuum heat treatment | ✓ In-house, ISO 9001 controlled | ✗ Sent out |
| PVD coating uniformity | ✓ ±2 µm | ✗ Inconsistent |
| Cpk capability | ✓ Cpk ≥ 1.33 | ✗ Not reported |
| Production capacity lock | ✓ 50,000 pcs / month, backup furnace | ✗ Single shift, no redundancy |
| PPAP / ISIR documents | ✓ On request | ✗ Not standard |
| Lead time (custom) | ✓ 4–6 weeks | ✗ 8–12 weeks |

FAQ
Frequently Asked Questions
Buyer questions about lead times, MOQ, NDA, samples, payment terms, PPAP and shipping. Not seeing your question here? Send it to our engineering team.
What is the typical lead time for a custom blade?
For most custom orders we ship within 4–6 weeks after drawing approval. The breakdown:
- Rough machining and forging: 1 week
- Heat treatment and sub-zero: 1 week
- CNC grinding and PVD: 1–2 weeks
- Final QA, docs and packing: 3–5 days
What is your minimum order quantity (MOQ)?
No hard MOQ for custom work:
- Prototype: 1–10 pieces
- Pilot run: 50–200 pieces
- Serial production: 500+ with capacity lock
Can you sign an NDA before we share drawings?
Yes — mutual NDAs before any technical exchange:
- Mutual NDA template available
- Drawings stored in restricted PDM
- No reverse-engineering of customer designs for third parties
Do you provide material certificates and PPAP?
Yes. Every batch ships with full traceability:
- Mill certificate (EN 10204 3.1) with heat number
- Hardness mapping + dimensional CMM report
- PPAP level 3 / ISIR on request for automotive
Which steel grades do you typically work with?
Full range of tool and high-speed steels per ASTM A681:
- D2 / 1.2379 — cold-work tool steel
- M2 / 1.3343 — high-speed steel
- SKD11 / DC53 — Japanese equivalents
- Carbide YG8 / YG15 for wear edges
What are the standard payment terms?
New customers: T/T 30 % deposit, 70 % against shipping docs:
- New customer: 30 / 70 T/T
- Returning: net-30 after third order
- Frame agreement with quarterly settlement on request
What shipping terms do you offer?
Ex-works, FOB and CIF all available:
- Ex-works Shanghai / Ningbo
- FOB Shanghai / Ningbo
- CIF to Hamburg, Long Beach, Santos, Dubai
Can you measure and re-engineer a worn blade?
Yes — one of our most common reverse-engineering workflows:
- Receive worn blade + failure description
- 3D scan and edge-profile measurement
- Improved geometry proposal within 5 business days
