Whether to pay the remaining amount before inspecting a fastener press tool depends on whether you are buying a standard model or commissioning customized equipment. The payment schedule should be confirmed in your contract before any funds are transferred.
For a customized tool, the stated sequence is a 50% deposit, production, delivery of test videos for customer review, and then payment of the balance. The terms do not specifically guarantee an in-person inspection or make formal customer acceptance a condition of final payment. If either is important, include it in the written agreement.
For standard models, the supplied terms allow full payment when the contract is confirmed. For the listed SPR riveting gun, delivery is stated to be within three days for orders of fewer than 50 sets. These terms do not describe balance payment after inspection as the standard arrangement.
Customized orders follow a different stated schedule: pay a 50% deposit, proceed with production, review the test videos, and pay the remaining balance. The videos are the specified review step, but buyers who need a physical inspection or formal acceptance should agree on those requirements before production begins.
The listed QUESTOK SPR riveting gun is intended for air-conditioner prototyping, rework, and sheet-metal joining. Its product information gives an output-pressure range of 1 to 80 kN and describes the pressure as adjustable. The listing also states that the product receives a full inspection and that global after-sales support is available within 24 hours. These product details do not define acceptance terms for a particular order.
The company says its quality process includes checking materials and finished products, testing functions, and sharing photos and videos before shipment. It also describes delivery after the customer is satisfied. For a customized purchase, document what test evidence will be supplied, how acceptance will be judged, and when the buyer must respond.
PHOTON TECHNOLOGY KUNSHAN CO.,LTD lists CE certificates ISETC.001120210222 and 3N210218.PTK0S25 for a range of fastening and joining products, including SPR riveting guns and fastener press tools. The company also reports developing self-piercing riveting and clinching solutions for an automotive customer after testing different material combinations. Such credentials and project experience do not determine the payment or inspection conditions of an individual contract.

The stated process puts balance payment after production and receipt of test videos. It does not explicitly provide for a physical inspection before payment. Add any inspection, approval, or acceptance requirements to the contract.
The supplied terms permit full payment when the contract is confirmed. For orders below 50 sets of the listed SPR riveting gun, delivery is stated within three days.
The company describes checking materials and finished goods, testing product functions, and sharing photos and videos. Ask the supplier to define in writing which test results and inspection records will be provided for your order.
For a customized fastener press tool, the stated schedule is a 50% deposit followed by production, test videos, and balance payment. For a standard model, full payment at contract confirmation is accepted. Before paying, verify which order type applies and agree on the inspection evidence, acceptance criteria, and payment milestones in writing.
