Every stage ends with something you can check: a missing-data list, a quotation that follows the confirmed drawing, a sample, written order and payment confirmation, a Thursday status update, pre-shipment readings, photos and video, shipping documents — and, if an issue occurs, a written root-cause report.
Each stage answers one buyer question and ends with something in your hands. You always know what is confirmed, what is open and what we need from you.
“Does this supplier understand my equipment?”
We identify the application, equipment and belt type, and list the information still needed.
You receive: A first reply with the missing-data list for your project
“Will this belt really fit my line?”
We review the old belt, drawing or photos, and check structure, dimensions, drive and operating conditions.
You receive: Review notes with confirmed and open technical points
“Is the price based on the right specification?”
Photos and basic dimensions support an indicative quotation. A formal quotation follows confirmed drawings or specifications. Any revision is marked and explained.
You receive: Indicative quotation, then formal quotation with changes highlighted
“What if the new supplier gets it wrong?”
Where the project requires it, a sample is made, compared with the drawing by photo, and sent for your confirmation before production.
You receive: Sample photos, then the physical sample for approval
“Will what we agreed be built exactly?”
Product, quantity, technical and delivery requirements are confirmed item by item. All special requirements are written into the order documents.
You receive: Proforma invoice and confirmed specification
“Did you receive our payment? Has production started?”
Once payment is received, we confirm it in writing and release the confirmed specification to production.
You receive: Written payment confirmation and production start notice
“Who keeps me informed?”
Active projects receive a status update every Thursday. Any drawing change follows a controlled revision.
You receive: Thursday status: current stage, completed items, pending actions, your actions, next milestone
“Is what we receive what we approved?”
Inspection data, photos and video are reviewed before packing. Replacement belts are compared with the original sample; belt–sprocket fit and drum photos are checked where applicable.
You receive: Pre-shipment inspection data, photos and video
“Will customs and receiving go smoothly?”
Packing is confirmed. A shipping email lists confirmed items and special requirements. Material and export documents are prepared for the applicable order.
You receive: Shipping email, packing list, material and export documents as confirmed for your order
“Is anyone responsible after delivery?”
Feedback is recorded. If an issue occurs, it is investigated against drawings, inspection records and operating conditions, and closed in writing. Repeat orders follow the recorded specification.
You receive: Problem, root cause, corrective and preventive action report; consistent repeat supply
Fit is decided by the system, not the belt alone. Drum (cage) diameter, turn ratio, running direction, sprockets, edge type and operating conditions are checked against your drawing, old belt or equipment data. If key data is missing, we tell you what is needed before giving a fit conclusion.
Many running problems come from mismatches that can be checked before production: direction, pitch, sprocket engagement, belt width and edge structure. These points are confirmed during review, and belt–sprocket fit or drum photos can be shared before shipment.
JBL sets project QC checkpoints from the confirmed drawing and confirms them with the production resources for your order. Before shipment, inspection data, photos and video are reviewed and shared with you.
Every active project receives a status update on Thursday: the current stage, what is complete, what is pending, what we need from you, and the next shipment milestone.
Set from your confirmed drawing and confirmed with the production resources for your order. You see the readings, photos and video before the crate is closed.
Raw material
Incoming material checked; material documents prepared as required for the order. A third-party laboratory material test report can be arranged on request.
Wire and component forming
Wire diameter, pitch and formed parts checked against the confirmed specification.
Welding and assembly
Weld points, edges and connections checked; burr and contact points reviewed. Tensile tests run on a tensile testing machine where the project requires it.
Functional tests
Drum-diameter, stacking, straightness or sprocket running tests, depending on the belt type.
Final dimensions
Width, pitch, rod and wire dimensions measured and recorded before release.
Packing and release
Packing method confirmed; pre-shipment photos reviewed before the crate is closed.
Each belt type has its own weak points. They are written into the order before production, not discovered after delivery.
| Belt | Typical risk points | How they are controlled |
|---|---|---|
| Spiral Freezer Belt | Drum diameter, turn ratio, running direction, edge structure | Confirmed against equipment data; drum-diameter testing before shipment |
| Self-Stacking Belt | Running direction (CW / CCW), stacking clearance, side-plate and support-rod alignment, uneven welding, colour variation after pickling | Direction confirmed at inquiry; first-piece check; drum-diameter, stacking and straightness tests |
| Eye Link Belt | Wrong pitch, unsuitable or bent reinforcement, surface residue | Pitch confirmed against the drawing before order; first-piece check; full pickling |
| Chain-Driven Belt | Chain joints, edge deformation, protruding welds, chain–sprocket–belt mismatch, surface residue | Complete first piece confirmed; welds finished smooth; trial assembly check |
| Balanced Weave Belt | Joining method, width out of tolerance causing tracking, sprocket pitch mismatch, uneven surface on small pitches | Joining, drive and wire confirmed at quotation; multi-point width and fit check before shipment |
| Flat Wire / Honeycomb Belt | Strip scratches, uneven gaps, wrong number of chains, insufficient finishing | Chain quantity confirmed at order; finished appearance check |
| Side-Driven Belt | Weld residue, turning mismatch with the existing system, clip problems, plastic part temperature limits | Weld cleaning; repeat orders checked against the previous order; operating temperature confirmed |
| Z-Type Ladder Belt | Number of openings, edge finishing and width, packing contamination | Confirmed against photos; packed clean and dry, labels removed |
| Sprockets | Marks on tooth faces, scratches, burrs | Tooth faces polished; deburring check; packed individually |
Replacing a belt on an existing line?
The same stages apply — starting from your old belt, photos or drawing.
Five steps: 1) you send a drawing, old belt photos or a sample; 2) we identify the belt and list what is missing; 3) structure, dimensions, drive and direction are checked against your equipment; 4) an indicative quotation follows, then a drawing for your confirmation; 5) where needed, a sample or trial length is made and approved before bulk production.
Material documents are prepared as required for the order, and a third-party laboratory material test report can be arranged on request. Tensile tests can be run on a tensile testing machine where the project requires it.
No. Photos with measurements, or a section of the old belt, are enough for a first review and an indicative quotation. The formal quotation follows the confirmed drawing or specification.
Where the project requires it, a sample is made, photographed against the drawing and sent for your approval before production starts.
Active projects receive a status update every Thursday: current stage, what is complete, what is pending, what we need from you and the next shipment milestone.
Inspection readings, photos and video — for spiral and self-stacking belts including the drum or stacking test — reviewed before the crate is closed.
JBL sets the project QC checkpoints from your confirmed drawing and confirms them with the production resources for your order, then reviews the evidence before release.
It is investigated against the drawing, inspection records and operating conditions, and closed in writing with the root cause and the corrective and preventive action.
Repeat orders follow the recorded specification, previous shipment photos and any special requirements from the earlier order.
They depend on the belt and the project, and are confirmed in writing in the quotation.
