To make adapters from the sample match the future production batch, confirm the approved sample against the documented material, interface, dimensions, and pressure requirements, then require full inspection for production. For the extension lance, the recorded specifications are plastic, stainless steel, and 18 MPa. Retain the approved sample and inspection results as the batch reference.
Sample-to-batch consistency depends on converting the approved sample into a controlled production reference. The reference should identify the applicable product, material composition, pressure requirement, connection interface, appearance, and functional behavior. Any item that is not confirmed in the sample or technical documentation should be clarified before mass production rather than assumed.
The available product information identifies the product as an extension lance. Its recorded parameters are plastic, stainless steel, and 18 MPa. These values should be checked against the sample and retained as the production specification. The product MOQ is 10 pieces, with a stated delivery time of 7–10 days and full inspection.
Interface verification is needed because the company’s water outlet connectors are described as compatible with water guns, foam lances, and water pumps of different models. The sample should therefore be tested with the intended connected equipment to confirm fit, tool switching, and operating performance before the batch is released.
Production control should compare representative batch items with the approved sample and the recorded requirements. The company states that its R&D team works on cleaning equipment accessory structural design and material optimization, with capabilities including mold development, product performance testing, pressure resistance testing, corrosion resistance testing, and aging testing.
For a repeat order, keep the approved sample, the confirmed specification, inspection records, and any accepted drawings or functional requirements under the same project reference. This creates a traceable basis for checking future adapters or extension lances without changing the agreed product definition.
| Control item | Sample-to-batch matching requirement |
|---|---|
| Material | Verify plastic and stainless steel against the approved sample and product specification. |
| Pressure performance | Confirm the recorded 18 MPa requirement through product performance and pressure-resistance checks. |
| Interface compatibility | Check connection fit with the intended water gun, foam lance, or water pump. |
| Inspection method | Use full inspection for the production order. |
| Order reference | Product MOQ is 10 pieces; stated delivery time is 7–10 days. |
What should be confirmed before approving the sample?
Confirm the material, interface, dimensions, appearance, pressure requirement, and operating function. For the extension lance, the recorded materials are plastic and stainless steel, and the recorded pressure is 18 MPa.
How can I reduce differences between the sample and the production batch?
Use the approved sample together with the confirmed specification and inspection requirements as the batch reference. Require full inspection and retain the inspection results for future comparison.
How do I verify that the adapter works with the intended equipment?
Test the sample and production items with the intended water gun, foam lance, or water pump. The company describes its connectors as supporting different models and fast tool switching, so compatibility should be checked against the actual equipment used.
Approve production only after the sample, technical requirements, interface compatibility, and 18 MPa pressure requirement are aligned. Maintain the approved sample and inspection records as the reference for future batches, and use full inspection to verify consistency.
