Quality Control Standards 
First Piece Inspection 
Process Inspection At REKO, every project starts with strict material control.
We only source raw materials from reputable and certified suppliers, and each batch comes with traceable documentation.
Many customers tell us they have experienced this with other suppliers:
Before machining begins, our engineers perform a rigorous review of customer drawings.
Our inspection workflow ensures dimensional stability throughout the entire production process.
Different material with different interval times for inspection
| Material | Inspection time of important size | Full inspection time | Remark | ||
| Intervals Time | Test items | Intervals Time | Test items | ||
| Aluminum | 30 mins | 1. Thread(Ring gauge and Thread gauge) 2. Inner hole(go-no go fixed gauges) 3. Key sizes | 60 mins | All sizes on the drawing | Adjust appropriately according to part size, tolerance, and appearance requirements. |
| Brass | 30 mins | 1. Thread(Ring gauge and Thread gauge) 2. Inner hole(go-no go fixed gauges) 3. Key sizes | 60 mins | All sizes on the drawing | Adjust appropriately according to part size, tolerance, and appearance requirements. |
| Stainless Steel | 15 mins | 1. Thread(Ring gauge and Thread gauge) 2. Inner hole(go-no go fixed gauges) 3. Key sizes | 45 mins | All sizes on the drawing | Adjust appropriately according to part size, tolerance, and appearance requirements. |
| Low carbon steel,iron | 20 mins | 1. Thread(Ring gauge and Thread gauge) 2. Inner hole(go-no go fixed gauges) 3. Key sizes | 45 mins | All sizes on the drawing | Adjust appropriately according to part size, tolerance, and appearance requirements. |
Surface finish plays a major role in final product quality.
Before any part goes to surface treatment, it must pass a 100% pre-finish inspection.
Remove burrs, tool marks, and sharp edges
Ensure consistent surface roughness (Ra control)
Group parts by material batch to prevent color variation
Confirm dimensional allowance for finishing thickness
All Parts must be fully checked before anodizing,It is to improve surface treatment quality rate.
| Item | NO. | Picture | Material | Color | Before anodizing | Order Qty. | Anodizing Qty. |
| 1 | Front_12x100 (PO1556-1) |  | AL7075 | Black | Full inspected | 25 | |
| 2 | 90200XX PO1559-1 |  | AL6082 | Anodized natural layer thickness 15um±5um | Full inspected | 11 | |
| 3 | EX2-T20 (PO1508) |  | AL6061 | Chemical grinding + anode black | Full inspected | 1000 | |
| 4 | 61315-BVF-T00 PO1545 |  | AL6061 | Black | Full inspected | 439 | |
| 5 | Leg Part PO1544-2 |  | AL6061 | Sandblasted 120#+ oxidized black pantone number: Black 6C | Full inspected | 500 | |
Remark:

| Consigner/Date: Approval: Consignee/Date: | |||||||
We will prepare a diagram of the mounting points and inform the surface treatment supplier of the exact positions of the anodized connection points. This will prevent them from mounting the components in the wrong positions, which could cause scratches on the product.
If the parts is with hole, and the hole with very high tolerance request. Will do the first piece anodizing for first checking, Then go aheard for the full order anodizing after first piece approved.
REKO has QC colleague worked in surface treatment factory,To control the quality and ensure the delivery time. REKO's QC will check the dimention in time after surface treatment done at the surface factory.
Color difference control, Check the color according to Color sample or Pantone code.
If the color rejected, will remake the color for the parts or do obsolescence.
Before packaging, every order must pass our strict outbound inspection.
Mixed batches in one shipment
Wrong or missing labels
Scratches from poor protection
Incorrect color or finish
"Three-Step Verification" before dispatch
Clear labeling with part number, batch, and quantity
Visual documentation of each shipment
Customized packaging for high-value components
Before packaging, every order must pass our strict outbound inspection.
Every project begins with a cross-department meeting to review drawings, tolerances, materials, and timelines.
Each batch moves with a unique traveler card for full traceability.
If an issue occurs, REKO provides professional root-cause analysis and preventive actions.
Material, finishing, and heat-treatment partners are scored monthly based on stability, consistency, and delivery performance.
Every feedback motivates us to do better.
