What Changes in a Metal Conveyor Belt for a Baking Line?
An oven belt touches every product you bake. Our factory builds baking belts to your old belt or drawing and confirms the surface, mesh and edge on the drawing you approve before production. See our metal conveyor belts.
Short answer
Choose a baking belt by the product and the oven zone: a flattened biscuit belt for thin biscuits in tunnel ovens, a compound or balanced weave belt for small or soft products that need a close surface, and a flat wire belt for open cooling and transfer.
I am Sunny Ye, Global Sales Director at YIYI MESH BELT in Ningjin, Shandong, China. Our manufacturing experience dates back to 1998. We make biscuit belts in 1.5 mm wire, plus compound, balanced weave and flat wire belts for baking and cooling.
At a glance
| Product | Biscuit Belt, Compound Weave, Balanced Weave, Flat Wire Belt |
|---|---|
| Application | Tunnel ovens, cooling and transfer in bakeries |
| Key parameters to confirm | Product size and type, oven drawing, temperature, surface, cleaning |
| Buyer type | Bakeries, biscuit plants, oven makers |
| What to send for a quote | Oven drawing or old belt, product photos, temperature and cleaning method |
Which belt fits which part of the line?
A baking line has different zones, and each may need a different belt.
In the oven, the belt must support the product evenly and handle heat: biscuit belts for thin biscuits, compound or balanced weave for small or soft products. In cooling and transfer, open belts such as flat wire let air through and are easy to clean.
| Zone | Belt | Why |
|---|---|---|
| Oven, thin biscuits | Biscuit Belt (flattened) | Thin, even surface |
| Oven, small or soft products | Compound or Balanced Weave | Close support |
| Cooling | Flat Wire or Balanced Weave | Open, airflow |
| Transfer | Flat Wire | Light, easy cleaning |
What makes a biscuit belt different?
A biscuit belt is woven, then rolled flat.
A biscuit belt is a woven mesh rolled flat after weaving, giving a thin, even surface that supports thin biscuits without marking them. We make biscuit belts in 1.5 mm wire, rolled flat to about 3 mm thick, with pitch, width, length and edge confirmed on the oven drawing.
Biscuit belts are rolled on a steel drum for shipment so the thin mesh cannot kink in transit.
What must be confirmed before ordering?
Oven belts are built to the oven, not to a catalogue.
Confirm the oven drawing or the old belt, the product and its smallest size, the temperature in each zone, the drive and tracking system, and the cleaning method. With these, the belt type, pitch, material and edge can be drawn and approved before production starts.
- OvenDrawing or old belt.
- ProductType and smallest size.
- HeatTemperature per zone.
- CleaningMethod and frequency.
How do you replace an oven belt?
Measure the old belt; the oven has already proved it.
To replace an oven belt, send a piece of the old belt or photos with a ruler: pitch over ten pitches, wire and belt thickness, overall width and the edge. We draw it, confirm with you, build it and check pitch, thickness and width before packing.
If the old belt marked products or baked unevenly, tell us; the surface or pitch may need to change rather than be copied.
When this is not the right choice
A flat wire belt is not right in the oven for thin biscuits; the openings mark the base.
A belt chosen without the oven drawing is not right; tracking and drive depend on the oven.
From our engineering experience
In November 2025 we shipped a flattened 1.5 mm biscuit belt: the wire was checked with a caliper, the mesh rolled flat on our mill, checked along its length and rolled on a steel drum.
My advice: send a piece of the old belt and a photo of the product on it. The two together show what the next belt needs.
Evidence from our work
- Situation
- A flattened biscuit belt for a customer’s oven.
- What we checked
- Wire 1.50 mm measured; mesh rolled flat on our flattening mill; checked along its length.
- Why it matters
- A thin, even surface is what makes a biscuit belt bake evenly.
- Result
- Rolled on a steel drum and packed for shipment.
- Buyer lesson
- Build the belt to the oven and the product, and protect it in transit.
FAQ
Which wire size do you make biscuit belts in?
1.5 mm wire, rolled flat to about 3 mm thick.
Can you match my old oven belt?
Yes, where it is made in 1.5 mm wire. Send a piece or photos with a ruler.
Which belt suits cooling?
An open belt such as flat wire or balanced weave, chosen by product size.
How are oven belts shipped?
Biscuit belts are rolled on a steel drum and packed in a wooden case.
Conclusion
Choose by oven zone and product: biscuit belts for thin biscuits, close weaves for small products, open belts for cooling. Build to the oven drawing.
