Quality Control
Quality Control for Tungsten Carbide Components
From raw material review to final packing, KENIN Carbide focuses on stable quality, dimensional accuracy, and practical inspection for custom carbide parts.
ISO-Standard Quality Control Process
Quality control is an important part of tungsten carbide manufacturing. KENIN Carbide follows ISO-standard quality control practices to help ensure parts are produced according to drawings, specifications, and application requirements.
Our inspection process is designed for practical industrial use: checking the details that affect fit, wear performance, assembly, and service life.
Material and Grade Review
Before production, the material grade should match the working condition of the part. Carbide grade selection may depend on wear resistance, toughness, impact conditions, corrosion exposure, and machining requirements.
For custom projects, we review the customer’s application and drawing requirements before confirming the production direction.
Hardness and Physical Property Checks
Tungsten carbide parts may require hardness checks and other material-related inspections depending on the order and product type. These checks help confirm whether the material meets the expected performance range.
- Hardness
- Density
- Material consistency
- Basic appearance after sintering
- Suitability for further grinding or machining
Dimensional Inspection
Dimensional accuracy is critical for carbide bushings, sleeves, valve seats, nozzles, tooling parts, and precision wear components. We check key dimensions according to drawings and agreed tolerances.
Inspection may include outer diameter, inner diameter, length, groove position, bore size, flatness, concentricity, and other important features depending on the part design.
Surface Finish and Appearance Review
Many carbide components require controlled surface finish, especially parts used in sealing, rotating, sliding, or flow-control environments. Surface finish checking helps reduce assembly issues and supports better working performance.
We also inspect visible defects, edge condition, chips, cracks, and packing condition before shipment.
Final Inspection and Packing
Before shipment, finished carbide parts are checked and packed according to product shape and transport needs. Protective packing is especially important for polished, ground, sharp-edged, or brittle carbide components.
Final review may include quantity, label, appearance, critical dimensions, and packing protection.
FAQ
What quality checks can be done for carbide parts?
Depending on the product, checks may include hardness, density, dimensions, surface finish, visual appearance, and final packing inspection.
Do you provide inspection reports?
Inspection reports can be discussed based on the order requirements and product type. Please request this before production.
Can you inspect parts according to my drawing tolerances?
Yes. Key dimensions and tolerances can be checked according to the confirmed drawing.
Why is surface finish important for carbide components?
Surface finish can affect sealing, sliding, rotation, wear behavior, and assembly performance, especially for sleeves, bushings, rings, and valve parts.
Can you help identify critical dimensions before production?
Yes. If you are unsure which dimensions are most important, we can review the drawing and discuss key inspection points with you.
Need Carbide Parts with Clear Inspection Requirements?
Send your drawing, tolerance requirements, and working conditions. We can review the inspection points before quotation and production.
