Replacing a Spiral Belt in Malaysia — Trial Run Approved, Turn-Tested, Then Bulk Production
A customer in Malaysia needed to replace the spiral belt on an existing line and supplied the drawing. A trial run was made, photographed and measured for approval, and samples were sent. Welds were ground a second time and the belt was laid out in a full circle to check the turn. After approval the customer ordered the bulk belt and installed it in place of the original.

01
The situation
Replacing the Original Belt — Without Changing the Line
The new belt had to run on the existing spiral exactly like the original: same pitch, same links, same turn. The customer supplied the drawing and wanted to see the belt before committing to the full order.
02
Reverse engineering
Trial Run Measured Against the Drawing
Every dimension that decides fit on the spiral was read with a caliper on the trial run and sent to the customer with the photos.
03
Sample before bulk
Trial Run Approved From Photos — Samples Sent
Before bulk production, the trial run was photographed and measured for the customer's approval, and samples were sent so the belt could be checked by hand. Welds and rod ends were ground a second time so the edge is smooth and free of burrs, and the mesh lies flat and closes evenly in the turn.
| Checked | Requirement | What was done |
|---|---|---|
| Dimensions | Per customer drawing | Pitch 27.40 mm · rod pitch 19.05 mm · link 2.72 mm |
| Weld finish | Smooth, no burrs | Welds and rod ends ground a second time |
| Mesh | Flat, even in the turn | Checked flat and in a full-circle turn test |
| Approval | Before bulk | Trial run photos approved; samples sent |

Turn test
Turn Test: The Belt Laid Out in a Full Circle
A spiral belt has to close evenly on the inside of the turn and open on the outside without lifting. The belt was laid out in a full circle to check how the mesh collapses on the inner edge and that the links follow the radius — before the crates were closed.

What This Project Shows Buyers
| Location · year | Malaysia · 2026 |
|---|---|
| Application | Replacement belt for an existing spiral |
| Starting point | Customer's drawing |
| Before bulk | Trial run measured and photographed for approval; samples sent |
| Finish | Welds and rod ends ground a second time — smooth, no burrs |

| Result | Approved, bulk ordered and installed in place of the original belt |
2.Grind the welds — the edge is what touches your line
Welds and rod ends ground a second time leave no burrs to catch guides or product.
3.Test the turn, not only the dimensions
Laying the belt out in a full circle shows whether the mesh closes evenly on the inside of the turn — the point a flat check cannot show.
4.Same readings on trial and bulk
Rod pitch read 19.05 mm on the trial run and 19.05 mm on the bulk belt — checked the same way before packing.
✓ Evidence on this page: trial run photos linked to the original, 8 caliper and tape readings on the trial run, a trial walk-through video, full-circle turn test photos, readings on the bulk belt and export packing. Customer name, order numbers and the original belt brand are withheld.

FAQ
Questions About This Project
Q1Can I approve the belt before bulk production?
Yes. In this project a trial run was measured and photographed for approval, and samples were sent before the bulk order.
Q2What is a turn test?
The belt is laid out in a full circle to check that the mesh closes evenly on the inner edge and the links follow the radius — how it will behave on the spiral.
Q3Are the welds finished?
Yes. Welds and rod ends were ground a second time so the edge is smooth, with no burrs to catch guides.
Q4Is the customer named?
No. Cases show country and year only; the customer, order numbers and the original belt brand are not published.
