Whether the balance is due before inspection depends on the type of fastener press tool you order and the payment schedule in your contract. For a customized tool, the described process is a 50% deposit, production, test videos for review, and then payment of the remaining balance. Standard models may be paid in full once the contract is confirmed. Make sure the inspection arrangements and payment milestones are clearly documented before sending funds.
For a custom solution, the stated sequence begins with a 50% deposit. After production, the supplier sends test videos, followed by the balance payment. The terms do not specifically guarantee an on-site inspection or make formal customer approval a condition of payment. If either is important to your purchase, add it to the contract along with the required evidence and acceptance process.
For a standard model, the supplier accepts full payment after the contract is confirmed. The listing states delivery within three days for orders of fewer than 50 sets of the specified SPR riveting gun. In this arrangement, payment after inspection is not identified as the usual sequence, so confirm the applicable terms before placing the order.
The QUESTOK SPR riveting gun is listed for air-conditioner prototyping, rework, and sheet-metal joining. Its specified output pressure is adjustable from 1 to 80 kN, and the product information describes its quality check as a full inspection. The listing also mentions global after-sales support within 24 hours. These specifications and service details do not, by themselves, define how your individual order will be inspected or accepted.
PHOTON TECHNOLOGY KUNSHAN CO.,LTD says its quality process includes checking incoming materials and finished products, testing functions, and sharing photos and videos before delivery. The company also states that delivery takes place once the customer is satisfied. For a customized order, ask the supplier to define in writing which tests will be performed, what records will be supplied, and when the balance becomes payable.

The company lists CE certificates ISETC.001120210222 and 3N210218.PTK0S25 for a range of joining and fastening products, including SPR riveting guns and fastener press tools. It also describes an automotive manufacturing project in which it tested different material combinations to develop self-piercing riveting and clinching solutions. These credentials and project examples provide background, but they do not replace order-specific inspection and payment terms.
Questok describes clinching for HVAC sheet-metal assembly as a one-step joining process that requires no consumables. The company lists ODM and OBM business models and accepts T/T, PayPal, credit card, and Alipay. Confirm the payment method and all contractual terms for your particular purchase.
The stated process for customized orders places test videos before the balance payment, but it does not explicitly require an in-person inspection or formal approval. Include any inspection and acceptance requirements in the contract before production begins.
The supplied terms allow full payment when the contract is confirmed. For the listed SPR riveting gun, delivery is stated as within three days for quantities below 50 sets.
The company says it checks materials and completed products, performs functional tests, and shares photos and videos. Agree with the supplier on the specific test results, records, and acceptance criteria that will be provided for your order.
For customized fastener press equipment, the described payment sequence is a 50% deposit, production, test videos, and then the remaining balance.
