Summary
This article shows the full manufacturing workflow for OEM cemented carbide components, covering IQC, in-process inspection and final quality control rules, helping buyers understand carbide OEM production stability and reduce prototype-to-mass production inconsistency.
Full Article Structure
1. Overview of OEM Cemented Carbide Manufacturing
OEM cemented carbide parts require stable process control from powder preparation to finished packaging. Different custom shapes, grades and tolerance demands will adjust the production route. A complete and traceable workflow helps reduce inconsistency between prototype and mass production for global buyers.
2. Step-by-Step OEM Production Flow
- Drawing review & process planning: Confirm grade, tolerance, shrinkage allowance and grinding margin
- Powder preparation: WC & binder mixing, wet milling and spray drying
- Compaction: Pressing or cold isostatic pressing for green blanks
- Sintering: High-temperature sintering to achieve target density and hardness
- Precision machining: Grinding, EDM, cutting according to drawing
- Surface treatment: Coating, polishing or edge treatment if required
- Final inspection, labeling and packaging
3. Multi-Stage Quality Control Checklist
| Inspection Stage | Main Test Items | Control Target |
|---|---|---|
| IQC Raw Material | Powder purity, particle size distribution | Match agreed grade specification |
| IPQC In-process | Green blank dimension, sintered hardness, density | Batch consistency check |
| FQC Finished | Dimension, tolerance, surface finish, appearance | 100% key dimension check for critical parts |
| OQC Before Shipment | Packing, marking, inspection document | Full set traceable records |
4. Common Defects & Preventive Measures
- Sintering crack: Control heating rate and powder lubricant proportion
- Dimension deviation: Optimize shrinkage coefficient and grinding allowance
- Uneven hardness: Stabilize milling time and sintering temperature curve
- Surface scratch: Improve fixture and diamond grinding process
5. FAQ: OEM Batch Production & Inspection Report
Q1: Can you provide inspection certificates for each OEM batch?
Yes, we can supply hardness, density and dimensional inspection reports as requested.
Q2: Is the sample process the same as mass OEM production?
We use identical production parameters for sample and mass order to keep performance consistent.
