In the competitive world of packaging machinery, precision and consistency mean everything. Every cut, slice, or seal depends on the quality of the cutting blades — and when downtime happens due to poor blade performance, it can result in significant production losses.
At Misiqi Blades, we specialize in OEM & ODM industrial knife manufacturing, helping equipment makers design cutting systems that achieve longer life cycles, cleaner cuts, and reduced maintenance costs.
This case study shows how we helped a leading packaging machine OEM overcome recurring performance issues through customized blade engineering.
1. The Client and the Challenge
Our client, a top-tier packaging machinery manufacturer in East Asia, produces high-speed film cutting and sealing machines used by global food and consumer goods brands.
They faced three key challenges:
-
Blade life too short — Standard SKD11 blades wore out within 2–3 weeks of continuous production.
-
Cutting inconsistency — After a short period, blades produced uneven edges, causing film tearing and sealing errors.
-
High replacement cost — Frequent blade changes led to high downtime and maintenance labor.
The client needed a custom blade solution that could handle continuous high-speed cutting of laminated packaging films (PET/PE, OPP/CPP, etc.) — without sacrificing accuracy.
2. Misiqi’s Engineering Approach
After analyzing the material flow and machine structure, Misiqi’s engineering team proposed a three-step optimization process:
(1) Material Upgrade
We replaced SKD11 steel with DC53 high-carbon tool steel, known for superior wear resistance and heat stability.
Through vacuum heat treatment and cryogenic processing, the final hardness was optimized to HRC 60–61, ensuring both toughness and edge retention.
(2) Blade Geometry Redesign
Our engineers adjusted:
-
Cutting angle: Optimized at 23° for smooth shearing of laminated films
-
Edge microfinish: Reduced surface roughness to below Ra 0.4 µm
-
Clearance tolerance: Maintained within ±0.01 mm for synchronized rotary cutters
These refinements allowed the blades to deliver cleaner cuts at high speeds exceeding 400 cuts per minute.
(3) Surface Treatment
To reduce friction and static adhesion from polymer films, we applied a TiN (Titanium Nitride) coating.
This not only prevented adhesive buildup but also improved wear resistance by over 40%.
3. Measured Results
After implementing Misiqi’s customized blades, the client achieved measurable improvements:
| Performance Metric | Before (Standard Blade) | After (Misiqi Custom Blade) | Improvement |
|---|---|---|---|
| Average Blade Life | 2–3 weeks | 8–10 weeks | +250% |
| Cutting Accuracy | ±0.15 mm | ±0.05 mm | +67% |
| Machine Downtime | 12 hrs/month | 4 hrs/month | –67% |
| Operator Complaints | Frequent | Minimal | — |
These results translated into significant savings on both maintenance cost و production loss, while improving product quality and machine reputation.
4. OEM Partnership Benefits
Following this success, Misiqi entered a long-term OEM cooperation with the packaging machinery manufacturer.
We now supply them with:
-
Batch production of customized blades with laser-engraved serial numbers
-
Technical drawing optimization and material consultation for each machine model
-
Annual tool performance review, helping their R&D team upgrade future designs
This partnership model ensures both sides benefit — the client gets reliable blades tailored to their systems, and Misiqi continuously innovates through real-world feedback.
