Why We Need Your Samples
To build a machine that performs as perfectly as possible — one that produces your specific products at the speed, quality, and consistency you require — we need your actual product samples for machine trial running.
This is not a formality. It is a fundamental requirement of our engineering process. A machine designed in theory is not the same as a machine validated in practice. The only way to confirm that a machine can handle your specific products — your band width, your material hardness, your housing geometry, your clamp diameter, your surface finish — is to run your actual samples through the machine and observe the results firsthand.Without your samples, we would be building a machine based on assumptions. With your samples, we build a machine based on
proven, tested, verified reality.
The Principle — The More You Send, the Better We Test
In theory, the more samples you send us, the more thoroughly we can test and adjust the machine. A larger sample quantity allows us to:
- Test across the full range of your product sizes — verifying that the machine performs correctly at every size in your catalog, not just at one or two representative sizes;
- Run extended production trials — confirming that the machine maintains consistent quality over hundreds or thousands of cycles, not just a few dozen;
- Identify edge cases and material variations — real production material is never perfectly uniform; having a larger sample pool allows us to observe how the machine handles normal material variation and adjust accordingly;
- Validate multiple assembly operations — testing cutting, forming, riveting, curling, screw engagement, and inspection across a statistically meaningful sample size;
- Fine-tune machine parameters — adjusting feed rates, forming pressures, welding parameters, curling diameters, and torque settings based on real-world data from your material.
However, we understand that practical considerations — cost, logistics, time, and effort — mean that sending an unlimited number of samples is not always feasible. That is why we have established clear guidelines to help you determine what to send, how much to send, and how to manage the process efficiently.
Practical Sample Requirements — What to Send and How Much
While more samples enable more thorough testing, we recognize that every sample you send represents real material cost and shipping expense on your side. To help you make the most of your sample shipment, we recommend the following:
Sample Category | Recommended Quantity | Purpose |
Finished product samples | 20 – 50 pieces per size | Reference samples showing the exact finished product you expect the machine to produce — used as the quality benchmark for machine adjustment |
Raw material samples | Sufficient length/quantity for 50 – 100 test cycles | Actual production material (steel coils, band strips, wire, components) — used to test the machine with your real material characteristics |
Component samples | 50 – 100 pieces per component type | Individual components (housings, clips, screws, springs, gaskets, O-rings) — used to test feeding, positioning, and assembly of each part |
Size range samples | At least 3 sizes covering your range | Samples representing the smallest, middle, and largest sizes in your product range — used to verify that the machine performs correctly across the full size spectrum |
Defective or marginal samples | 5 – 10 pieces (if available) | Samples with known defects or borderline quality — used to verify that the machine's inspection systems correctly identify and reject non-conforming products |
Minimum recommended shipment: At minimum, we need enough samples to complete a meaningful production trial — typically 50 to 100 finished clamps across your key sizes, plus corresponding raw material and component samples.
Ideal shipment: For the most thorough machine validation, we recommend sending samples sufficient for 200 to 500 test cycles — allowing us to run extended production trials, perform statistical quality analysis, and fine-tune the machine with high confidence.
Before You Ship — What to Prepare
Before sending your samples, please prepare the following information and include it with your shipment:
Item | Details to Provide |
Product drawings or specifications | Technical drawings, dimension sheets, or specification documents for each clamp type and size included in the sample shipment |
Material certificates | Material grade certifications (e.g., AISI 304, AISI 316, galvanized steel grade) for the raw materials included |
Quality standards | Your acceptance criteria — torque specifications, dimensional tolerances, visual inspection standards, surface finish requirements |
Sample identification | Clear labeling of each sample batch — indicating product type, size, material grade, and any special notes about the samples |
Quantity manifest | A detailed packing list showing exactly what is included in the shipment — quantities, types, and sizes of all samples and materials |
Special instructions | Any specific testing requirements, priority sizes, or particular concerns you want us to focus on during the trial run |
Providing this information with your samples eliminates guesswork, accelerates the testing process, and ensures that our engineers evaluate your samples against the correct standards from the very first test cycle.
Shipping Cost Responsibilities — A Transparent Breakdown
We believe in full transparency regarding the costs associated with sample shipping — particularly for international shipments, where multiple cost components are involved.
Domestic Shipping (Within China)
For customers located within China, shipping is straightforward:
Cost Component | Responsibility |
Freight / courier cost | Borne by the customer (sender) |
International Shipping
For international customers, the cost structure is more complex. Multiple cost components are involved, and the division of these costs should be negotiated and agreed upon by both parties before the shipment is dispatched.
Cost Component | Description | Typical Responsibility |
Freight / courier cost | The base transportation cost for shipping the sample package from the customer's location to Frand's facility in Xiamen, China | Borne by the customer (sender) |
Customs clearance fee | The fee charged by customs brokers or agents for processing the shipment through Chinese customs upon arrival | Should be negotiated between both parties beforehand |
VAT (Value Added Tax) | Import VAT levied by Chinese customs on the declared value of the imported samples | Should be negotiated between both parties beforehand |
Import duties | Tariffs or duties applicable to the imported sample materials, based on the applicable HS code and trade agreements | Should be negotiated between both parties beforehand |
BAF (Bunker Adjustment Factor) | A fuel surcharge applied by shipping carriers to account for fluctuations in fuel prices — common in international ocean freight and express courier services | Should be negotiated between both parties beforehand |
Bank transfer fees | Any banking charges incurred when transferring payments related to sample shipping costs | Typically borne by the party initiating the transfer |
Our recommendation: Before shipping your samples internationally, please discuss the cost allocation with your Frand contact. We are flexible and reasonable — our goal is to make the sample exchange process as smooth and cost-effective as possible for both parties. In many cases, we can suggest shipping methods or customs procedures that minimize total costs.
How to Minimize Your Sample Shipping Costs
We understand that international shipping costs can be significant. Here are practical tips to help you manage these costs effectively:
- Consolidate your samples — send all samples for all sizes and types in a single shipment rather than multiple separate shipments;
- Choose the right shipping method — for small, lightweight sample packages, international express courier (DHL, FedEx, UPS) is often more cost-effective than air freight; for larger or heavier shipments, air freight may be more economical;
- Declare accurate values — work with your Frand contact to determine the appropriate declared value for customs purposes — samples for machine testing purposes may qualify for reduced duty rates or temporary import procedures;
- Use sample labeling — clearly marking the package as "COMMERCIAL SAMPLES — NOT FOR RESALE — FOR MACHINE TESTING PURPOSES ONLY" may help reduce customs duties in some jurisdictions;
- Plan ahead — allow sufficient time for customs clearance so that your samples arrive at our facility without unnecessary delays or storage charges.
What Happens When Your Samples Arrive
Once your samples arrive at our facility in Xiamen, the following process begins:
Step | Action |
Receipt and inspection | We receive your shipment, verify the contents against your packing list, and inspect the samples for any shipping damage |
Material analysis | Our engineers analyze your samples — measuring dimensions, testing material hardness, examining surface finish, and documenting the characteristics of your specific products |
Machine configuration | Based on the sample analysis, we configure the machine's tooling, forming dies, feeding systems, and process parameters to match your products |
Trial running | We run your samples through the machine — producing test clamps and evaluating the results against your quality standards |
Adjustment and optimization | Based on the trial run results, we fine-tune the machine — adjusting parameters, modifying tooling, or reconfiguring stations as needed to achieve optimal performance |
Extended testing | We run extended production trials to verify consistent quality over hundreds of cycles |
Results reporting | We share the trial run results with you — including production speed, quality data, sample clamps produced, and any recommendations for your production process |
Sample return or disposal | Upon request, we can return your original samples and finished test pieces to you — or dispose of them according to your instructions |
The Bottom Line
Your samples are the bridge between a machine that is designed on paper and a machine that performs in production. They are the single most important input in our ability to build a machine that is perfectly matched to your products, your materials, and your quality standards.
We understand that sending samples — especially internationally — involves cost, effort, and coordination. We are committed to making that process as transparent, efficient, and mutually beneficial as possible.
Send us your samples. We will build you a machine that proves their value.
