跑俩月就磨穿跑偏，停线赔几万
输送带是“承载耐磨的件”：耐磨、耐油、承载。材料要耐磨、耐油、承载稳——结论先给：输送带用 TPU 是主流；高温输送，复合结构留。
输送带最大的坑：首次试料，先试200kg。大货前先试 200kg——小批试料，是输送带的保险。
输送带是功能件：磨穿、断裂都是问题。材料选对，产线才稳——功能件，别省料钱。
输送带为什么用 TPU
输送带用 TPU 的理由：耐磨好、耐油好、承载稳、寿命长——四条合起来，适合输送带。
耐磨是核心：物料摩擦。耐磨测试写进验收——磨穿，就是问题。
耐油不能省：接触油污。耐油测试写进验收——溶胀，就是问题。
承载摩擦油污，三道关
承载工况：物料承载。承载数据要验——拉断，就是问题。
摩擦工况：运转摩擦。耐磨数据要验——磨穿，就是问题。
油污工况：接触油污。耐油数据要验——溶胀，就是问题。

The conveyor belt wears through and runs off track after just two months, and a one-day stoppage costs tens of thousands. If the abrasion-resistant and oil-resistant conveyor belt is not chosen correctly, transporting materials will just become money burning.
After running for two months, the runners wore out and went off track, stopping the production costs tens of thousands.
The conveyor belt is a 'load-bearing wear-resistant component': wear-resistant, oil-resistant, load-bearing. The material must be wear-resistant, oil-resistant, and stable in load-bearing—the conclusion first: using TPU for conveyor belts is mainstream; for high-temperature conveying, a composite structure is retained.
The biggest pitfall of conveyor belts: When testing materials for the first time, start with 200kg. Before mass production, test 200kg first — small batch testing of materials is the insurance for the conveyor belt.
The conveyor belt is a functional component: wear-throughs and breakages are problems. Choosing the right material ensures a stable production line—functional components, don’t skimp on material costs.
Why are conveyor belts made of TPU?
Reasons to use TPU for conveyor belts: good wear resistance, good oil resistance, stable load-bearing, long service life—combined, these four factors make it suitable for conveyor belts.
Wear resistance is key: material friction. Wear resistance testing is written into acceptance—wearing through is the problem.
Oil resistance cannot be compromised: it comes into contact with oil stains. Make sure to include oil resistance testing in the acceptance inspection—swelling is a problem.
Bearing friction oil and dirt, three checkpoints
Load condition: material carrying. Load data needs to be tested — breaking, that is the issue.
Friction condition: operating friction. Wear resistance data must be tested—if it wears through, it's a problem.
Oily condition: Contact with oil. Oil resistance data needs to be tested—swelling is the problem.
TPU or rubber? Conveyor belt at a glance
| Dimension | TPU | Rubber |
|---|
| Wear-resistant | Strong | middle |
| Oil-resistant | Good | Visual glue type |
| Bear; carry; support | Good | Good |
| Cost | Medium-high | Medium-high |
| Efficiency | extrude | Vulcanization |
| Purpose | mainstream | Special |
Table reading: TPU is wear-resistant and oil-resistant; rubber is good for special conditions—for conveyor belts, TPU is mainstream.
Select according to working conditions: special rubber, conventional TPU.
Conveyor belt acceptance: first test with a small batch of 200kg
| Project | Quantity | Check |
|---|
| First attempt | 200 kg | Performance |
| Retest | Batch | Stable |
| Trial Production | small batch | Craft |
| Increase in volume | bulk goods | Contrast |
Form reading: Start small and take it step by step, only then is large-scale production stable — first run 200kg for extrusion and wear resistance tests, and once it passes, scale up to larger batches.
Small batch trial material is the insurance for the conveyor belt.
Go straight to mass production, three issues
Pitfall 1: Going straight to mass production. Jumping straight into mass production can lead to the entire batch being scrapped if it isn't wear-resistant — always test with small batches first.
Pitfall 2: Oil resistance leakage test. Swelling — oil resistance test, must be tested.
Pitfall 3: Overstated wear resistance. Wear through — wear resistance should be measured and accepted based on actual tests.
First test a small batch of material on the conveyor belt
Three questions: How much for the initial test, what standard for wear resistance, what medium for oil resistance. One verification: actual operation measurement — with three questions and one verification, the supplier's details are clear.
Small batch verification must be done first: 200kg of test material should be run through for wear resistance and extrusion stability. Test small batches first, then discuss large orders—the small batch test material is the insurance for the conveyor belt.
Making sample retention a habit: retain samples from each batch, and retest for wear and oil resistance batch by batch. When changing materials between batches, compare first before increasing the volume—stable batches mean fewer customer complaints.
Conveyor belt: Clear mines according to this chart
| Phenomenon | Reason | Countermeasure |
|---|
| wear through | Insufficient wear resistance | Replace wear-resistant material |
| Swelling | Insufficient oil resistance | Replace with oil-resistant material |
| tear off | Insufficient load-bearing | Add enhancement layer |
| slip | Insufficient friction | Replace with high-friction material |
| Batch Drift | Formula fluctuation | Lock window |
Mainstream conveyor belt TPU, Shore A 85-95, wear resistance measured batch by batch according to wear amount. TPU's wear and oil resistance is its specialty; too soft and it deforms under load, too hard and it damages materials — most sales are around A90.
TPU is wear-resistant, oil-resistant, and efficient, while rubber belts have good anti-slip properties but are heavy and require vulcanization. For food conveying, look at food-grade TPE; for heavy-duty wear resistance, look at TPU—choose according to the material and the floor.
A conveyor belt wearing through is not because the material is not wear-resistant, but because the joint method and tension were not designed properly. Heat splicing, cold splicing, and mechanical joints have different strengths, and if the tension is off, it wears faster—first check the joint strength.
For the first trial batch, start with 200kg; it's enough for verification without overstocking. Make sure to pass the tests for wear resistance, oil resistance, and joint strength before discussing mass production—going straight to full-scale production is like gambling with the production line.
Small batch trial materials lock in the dimensions and wear resistance, and the customer placed follow-up orders for three consecutive batches. Samples from each batch are kept to measure wear and dimensions, and when switching systems, we first trial produce a small batch before scaling up.
The strength of conveyor belt joints is graded according to hot splicing, cold splicing, and mechanical splicing, and tension deviation causes faster wear. TPU is highly efficient in wear and oil resistance. For heavy-duty wear resistance, look at TPU; for food conveyor belts, consider food-grade TPE. Check the joints first before discussing wear.
For the first trial material, start with 200 kg, and only increase the quantity after successfully passing the three wear-resistant and oil-resistant joint tests. Measure ground friction according to actual working conditions, record tension design in the acceptance, and for each batch, keep samples to measure wear and dimensions.
The joint strength is classified according to the method, and the tension design is written into the acceptance. Samples from each batch are kept to measure wear and dimensions, the first trial material of 200 kilograms must pass three checks before scaling up, and ground friction is verified based on actual measurements.
First check the strength of the conveyor belt joints before discussing wear. For heavy-duty TPU food-grade TPE, choose according to the material and ground; the strength of hot, cold, and mechanical joints differs. For the first trial, run 200 kilograms of material through three tests.
Add wear and dimensions for each batch sample.
For each batch of conveyor belts, samples are taken to measure wear and dimensions. For the first trial material, 200 kilograms are tested through three checkpoints. The joint strength is checked for tension before discussing wear. Going straight to full-scale production would be gambling with the production line, and ground friction is measured as actual.
Cologne Customer Case: Unstable shrinkage and size fluctuations, continued three orders after changing the system
An industrial equipment factory in Zhongshan is experiencing unstable contraction rates and large size fluctuations in its conveyor belts. With Cologne's assistance in changing the system and switching grades (from SEBS-based to TPV-based), the size became stable, and the customer placed follow-up orders for three consecutive batches. By changing the system, the size issue is addressed from the source—the contraction rate problem should first look at system stability.
Summary
For the selection of the conveyor belt, start with a small batch trial, then test for wear resistance. For the first trial material, test 200 kg first. Small batch trial is a precaution.
First make things clear, then talk about the price.
For some orders, we would rather say 'this component is not suitable with our material' than take them forcefully. Choosing the wrong type means that even if it's cheap, it is expensive. Sub-brand materials are not genuine; there is a line between usable and unusable, and we are clear about that line.
