便宜三成的料，一烧就穿帮
TPE 原料辨真，原包码是线索：喷码、复称、批次。结论先给：原包码会说话，复称喷码都查——喷码，是原料的身份证。
TPE原料真假最大的坑：喷码和批次号对不上，料八成有问题——喷码，是原料的照妖镜。
辨真是成本关：掺假料，一吨亏一吨。会辨真，省的是真金——辨真，是采购的基本功。
掺假防不胜防，为什么先认原包码
掺假常见手段：掺水口、掺回料、换包装。手段多，要会查——手段，是辨真的对象。
原包码会说话：喷码批次对得上。码乱，料就乱——喷码，是原料的身份证。
复称是照妖镜：重量对不上，料有水分。复称，是辨真的尺子。
喷码、复称、批次，怎么辨真
喷码：核对品牌批次。码对不上，直接拒——喷码，是头一查。
复称：袋重核对。重量不符，查原因——复称，是第二查。
批次：喷码追溯。批次可查，料才可信——批次，是第三查。

Original packaged materials that are 30% cheaper will break through as soon as they are fired. Original package codes can speak for themselves; both spray codes and reprints need to be checked.
Cheap material at 30% off will break through as soon as it's fired.
Identifying the authenticity of TPE raw materials, the original package code is a clue: spray code, reweighing, batch number. Here's the conclusion first: the original package code can speak, and both reweighing and spray codes should be checked — the spray code is the ID card of the raw material.
The biggest pitfall in determining the authenticity of TPE raw materials: the spray code and batch number don't match, and the material is likely problematic — the spray code is a revealing mirror of the raw material.
Recognizing authenticity is a matter of cost: with adulterated materials, you lose a ton for every ton. Being able to recognize authenticity saves real money — recognizing authenticity is a basic skill in procurement.
Adulteration is hard to guard against, so why first recognize the original package code?
Common methods of adulteration: adding water, mixing in recycled materials, changing packaging. There are many methods, so one must know how to check—the methods are what you use to identify the genuine product.
The original package code can speak: the inkjet batch matches. If the code is messed up, the material is messed up — the inkjet code is the ID card of the raw material.
Reweighing is like a demon-reflecting mirror: if the weight doesn't match, the material has moisture. Reweighing is a ruler for distinguishing authenticity.
Inkjet coding, reweighing, batch numbers, how to tell if they're genuine
Inkjet code: Check the brand and batch. If the code doesn’t match, reject it immediately—inkjet code is the first thing to check.
Reweigh: check the bag weight. If the weight does not match, find out the reason—reweigh, this is the second check.
Batch: inkjet code traceability. Batches can be checked, materials are trustworthy—batch is the third check.
Methods to distinguish the real, clearly compared in a chart
| means | Check what | Judgment |
|---|
| Inkjet coding | Brand batch | Must check |
| repetition | Bag weight | Must check |
| Appearance | Particle | Must check |
| Physical properties | Actual measurement | Must check |
Form reading method: Check each item one by one without missing any, and weigh both the original package coding and the net weight.
With all methods employed, the fake materials are exposed.
Original packaging with authentic batch clearance, check these four items upon receipt
| Project | Requirement | Judgment |
|---|
| Inkjet coding | consistent | Meet the standard |
| repetition | Match | Meet the standard |
| Appearance | Normal | Meet the standard |
| Physical properties | Actual measurement | Meet the standard |
Table reading method: Check each item to distinguish true from false, see the truth clearly, and cross-check the weight and printed code characters.
Coding is the ID card of raw materials.
Only looking at the price without checking the ink code will invite counterfeit goods.
Pitfall 1: Only look at the price. Trust it just because it's low, and the coding can easily rub off—the coding must be verified.
Pitfall 2: Weighing but not recording. Adulteration — double weighing must be done.
Pitfall Three: Unmeasured physical properties. Fake materials — physical properties must be measured.
Spray coding, reweighing, batch — check before receiving
Three questions: what brand, what batch, what weight. One verification: re-measure the physical properties — three questions and one verification, the supplier's details are clear.
Spray code verification must come first: first match the original package spray code, re-weighed net weight, and batch number, then talk about the price per ton—spray code is a mirror revealing the true nature of the raw materials.
Making sample retention a habit: retain samples for each batch, and re-test the physical properties by batch. Before switching materials between batches, compare them first before scaling up—the batch is stable, and customer complaints are few.
Adulteration, Package Swapping, Material Mixing: Compared in a Table
| Phenomenon | Reason | Countermeasure |
|---|
| The code is incorrect | Change packaging | Refuse to accept |
| Lightweight | Watered down | repetition |
| Miscellaneous grains | Water injection port | Appearance inspection |
| Poor physical properties | recycled material | Actual measurement |
| Customer complaint | Verifying True Pine | Set standards |
It's impossible to completely prevent adulterated materials, but the original package code can reveal the truth. By looking at the bag printing, bag weight, and granules together, counterfeit materials can't hide.
Focusing only on price is bound to fail. Check all four aspects together: coding, reweighing, appearance, and physical properties, without leaving any out. Only when all are checked will adulterated materials be exposed; missing even one check might result in it being overlooked.
The bag's repeated weighing matches, the granules are uniform with no color impurities, and the spray code batch is consistent with the original factory. If it doesn't match, it's questionable. Cheap testing can filter out a large batch, so don't wait until it's on the machine to find out.
Authenticity inspection is the 'inspection post' for procurement, with three checks: original packaging code, re-weighing, and physical properties. Press the hardness tester, weigh with the density cup, and if they don't match, eliminate it. If it doesn't pass the threshold, no need to discuss further.
Pass all four tests, the physical properties measured match, and the TDS is consistent; only then sign for the original packaging genuine material. Those who just say it’s original packaging or provide reports from a different brand are directly excluded; authenticity is not determined by words.
Three ways to identify fakes: batch code printing, repeated bag weighing, and particle cross-section. The original bag's weight deviation is ±0.2kg. Bags with blurred batch code printing or lighter weight are directly suspicious, and cheap testing filters out a large batch.
Before using the machine, test the density and melt index first. If they don't match the TDS, reject it. Weigh the density cup, test the melt index, press the hardness tester; if any of the three items don't match, don't use the machine. Returning adulterated material after using the machine is even more expensive.
Check the hardness with a hardness tester and weigh with a density cup; if they don't match, eliminate it. For inkjet coding, reweighing, appearance, and physical properties, all four items are checked together without omission. Only adulterated materials get exposed; if one item is checked less, it may be missed, and if it doesn't match, it is considered suspicious.
Packaging bag spray code bag heavy particles, looking at the three together reveals fake material that can't be hidden
Checking the four aspects of inkjet coding, appearance, and physical properties together ensures that no adulterated materials slip through. If only one aspect is checked, something may be missed. If it doesn't match, it raises suspicion. Cheap tests can screen out a large batch, so don’t wait until it goes on the machine to find out.
Cologne Customer Case: Unstable Shrinkage Rate with Large Fluctuations, Small Batch Trial Production Continues with Three Orders
A modified material application factory in Zhongshan found that the shrinkage rate of TPE raw materials was unstable, resulting in large dimensional fluctuations. After Cologne cooperated with a small batch trial production for verification before scaling up, the dimensions stabilized, and the customer placed repeat orders for three consecutive batches. During the small batch trial production, lock in the dimensions before scaling up — for dimensional issues, first check the drying of the material and then the parameters.
Summary
TPE raw material is purchased after authenticity verification, the spray code is checked first, and re-weighing is done afterward. The original packaging code can speak for itself, and both re-weighing and spray codes are checked. The spray code is like an ID card.
We are standing between the resin factory and the injection molding factory.
