Do you support custom low MOQ manufacturing?

It mainly depends on which process is most suitable for the product, and lower volumes generally come with a higher cost per unit.

How long does it take to receive a quotation?

It usually takes about 3–5 working days once we get your drawings and expected order volume.

Are your unit prices competitive?

Because we collaborate with a diverse range of partner factories, we are able to recommend suitable manufacturing processes and offer competitive pricing. 

Most components involve more than one production step, and through Unitedparts' services we integrate every stage into a seamless process—from manufacturing to final delivery.

Yes.

What if defects are found upon delivery, and how will Unitedparts handle and trace them?

If defects are found upon delivery, please follow these steps:
 

  1. Immediate notification: Take photos, contact us, and provide a Defect Report (NCR).

  2. Cause review & corrective action: We check the process with factories to identify the issue and take corrective action.

  3. Customer update & resolution: Once the cause is identified, we will inform you at once and discuss the right solution, such as refund or replacement.

  4. Inventory check: At the same time, we inspect and remove related stock to prevent repeat issues in future shipments.


We use order numbers and inspection records to trace manufacturers, resolve issues, and ensure processes remain controlled with consistent quality.
