In short: Quality is held at seven documented control points from drawing release to shipment, measured with 17 calibrated instruments, and closed before dispatch.
Every manufacturer says they inspect. Inspection, on its own, only tells you whether a defect was caught at the end — it says nothing about whether the defect was created in the first place.
The distinction that matters to a buyer is this:
A factory can own good instruments and still ship a wrong ride — if the drawing was not the current revision, or if a rework was signed off without re-inspection. That is why this page describes the system first and the instruments second.
| # | Control point | What happens | Record produced |
|---|---|---|---|
| 1 | Design & drawing release | Structural calculation issued before manufacturing drawings. Drawing revision controlled; only the current revision reaches the shop floor. | Calculation report, drawing register |
| 2 | Incoming material | Steel checked against mill certificate: grade, hardness, actual plate thickness. Undersized or substituted material rejected before fabrication. | Material certificate, incoming inspection record |
| 3 | Fabrication & welding | Weld size checked against drawing; critical joints inspected by magnetic particle and ultrasonic testing. Defects ground out and re-welded. | Weld inspection record (MT / UT) |
| 4 | Surface treatment | Blast grade verified before painting; primer and topcoat thickness measured in microns. Under-blasted surfaces re-blasted, never painted over. | Blast grade record, coating thickness record |
| 5 | Assembly & trial run | Full assembly, electrical insulation and earthing tests, then a running test with actual speed measured by radar before dismantling for shipment. | Trial run record, electrical test results, measured speed |
| 6 | Pre-shipment | Packing list and container loading checked; third-party inspection (SGS or your nominee) scheduled if required by contract. | Pre-shipment inspection report |
| 7 | Non-conformance closure | Every failed reading opens a record: what failed, what was done, who signed it off. Closed before the item moves to the next stage. | Non-conformance and rework record |
Each control has an owner and a record. A ride cannot move to the next stage with an open non-conformance — that is the part that actually holds the system together, not the checklist itself.
Our quality management system is certified to GB/T 19001-2016 / ISO 9001:2015 under certificate HQ-Q20268921, issued by Global International Standard Testing and Certification Center. The certificate is valid from 4 November 2026 to 3 November 2029 and carries UKAS, IAF and CNAS marks.
The certified scope covers the manufacture of amusement equipment, indoor amusement equipment, toys, sporting goods and recreational boats — that is, the production activities this site describes, not a separate business line.
This is a management-system certificate, not a product certificate. It says the process is controlled; it does not say that every ride conforms to every standard — that is what the calculation report and the records above are for.
The controls above are only as good as the numbers behind them. We verify five properties in-house, with 17 instruments on a scheduled calibration cycle.
| What we measure | Instruments | What it proves |
|---|---|---|
| Weld integrity | Magnetic particle (MT), ultrasonic (UT), weld gauges | No surface cracks, no internal lack of fusion, correct weld size |
| Material & coating | Leeb hardness, ultrasonic thickness, coating thickness, blast comparator | Correct steel grade, actual plate thickness, paint build-up, blast grade |
| Installation geometry | Levels, digital inclinometer, bevel protractor, slope gauge, tapes | Tracks level, columns vertical, angles and gradients as drawn |
| Electrical safety | Insulation resistance, earth resistance, multimeter, clamp meter | Insulation and earthing protect passengers if a fault occurs |
| Running speed | Handheld radar speed gun | Actual speed matches the speed assumed in the structural calculation |
Welds carry the ride. A weld that looks perfect can still contain lack of fusion, slag inclusion or internal cracks, and those defects grow under cyclic loading.
Two of the most common ways a ride is quietly weakened are thinner steel than specified and thinner paint than promised. Both are measurable.
A ride that is geometrically wrong puts loads where the calculation did not assume them. This is measured at installation, not assumed from the drawing.
Electrical faults on a ride are a passenger-safety issue, not only an equipment issue.
Design speed and actual speed are two different numbers. The second one is what passengers experience and what the ride’s dynamic loads were calculated for.
A handheld radar speed gun measures actual running speed on track rides and rotating equipment. If the measured speed exceeds the design value, the ride is re-tuned before handover — because every load case in the structural calculation assumes a specific speed.
Few manufacturers publish this check. It is the one that most directly links the calculation report to what the ride actually does.
The value of a control point is decided at the moment something fails, not when everything passes.
| What failed | What happens |
|---|---|
| Weld defect | Joint ground out, re-welded, re-inspected by MT/UT. No shipment with an open note. |
| Undersized steel | Rejected before fabrication, not “used up on a smaller part”. |
| Coating too thin | Re-coated and re-measured. |
| Under-blasted surface | Re-blasted. Paint is never applied over a failed profile. |
| Electrical test fail | Circuit not energised until it passes. No ride is commissioned on a “we’ll fix it on site” basis. |
| Speed above design | Re-tuned before handover, not after the first passenger. |
Every one of these opens a written record: what failed, what was done, who signed it off. The record is closed before the item advances. This is the mechanism that makes the other six controls more than paperwork.
An instrument that is not calibrated measures nothing useful, and a calibration certificate that cannot be produced is worth nothing in an audit.
All 17 instruments are on a scheduled calibration cycle. Certificates are available with the project documentation on request — including for the instruments used on your project specifically, not just a generic list.
Each inspection produces a record: what was measured, the reading, the tolerance and the disposition. These records are compiled into the project quality file rather than kept in a drawer.
If your project requires a specific standard or a notified body, tell us at inquiry stage — the inspection plan is agreed before production, not after.
No. ISO 9001 is a quality management system standard covering the whole organisation, and our system is certified to it. What is described on this page is the manufacturing control layer that a buyer can actually verify on a specific order — the seven control points, the measurements, and the non-conformance loop. A management-system certificate does not make an individual ride conform; the records do.
Yes, at any stage, and we schedule the trial run around their availability. Inspectors are given access to the inspection records, not only the finished ride.
Critical joints on every ride are inspected with magnetic particle testing. Ultrasonic testing is applied to full-penetration butt welds on primary structural members. The inspection scope is written into the project quality plan before production starts.
The joint is ground out, re-welded and re-inspected. Under-thickness coating is re-coated, under-blasted steel is re-blasted. Nothing ships with an open non-conformance.
Yes. All instruments are on a scheduled calibration cycle, and certificates are available with the project documentation.
No. In-house inspection is a manufacturing control; it does not replace the certification your local authority requires. What it does is produce the records a third-party inspector or notified body will ask for, which makes their job faster and your approval less risky.
Inspection scope and acceptance criteria follow the governing standard for the project — normally EN 13814 for European destinations. See our comparison of EN 13814, CE and GB 8408 for what each standard actually requires.
Yes. The quality file is normally compiled before shipment, and reviewing it before the balance payment is a reasonable request — ask for it in the contract.
