Once a batch of test material passes, ramp up to mass production; the third batch fails completely. One batch shows no fluctuations; after three stable batches, increase production.
The first batch was ramped up once qualified, the third batch completely collapsed.
TPE samples are a 'test of patience': batch one, batch two, batch three. Here's the conclusion first: only when batch three is stable can mass production be started, don't rush—batch three is the health check for mass production.
The biggest pitfall of TPE samples: once one batch passes, it goes into mass production, experiencing all the batch fluctuations—three batches are the insurance for mass production.
Samples are a quality checkpoint: if three batches are stable, mass production will be stable. Rushing to launch leads to rework—samples are a rehearsal for mass production.
A batch that shows no fluctuation, why make three batches?
One batch is a coincidence: the data is good, it might be luck. One batch is a single point.
The second batch is for verification: only if it is repeated can it be trusted. The second batch is for verification.
Three batches ensure stability: only after continuous passes can we be assured. Three batches are the bottom line.
Parameters, physical properties, yield rate—what should three batches focus on?
Parameters: The three batches of parameters are consistent. Only when the parameters are stable can they be replicated—parameters are the basis of the sample.
Material properties: Comparison of material properties across three batches. Material properties must be stable to meet the standard—material properties are the test results of the samples.
Yield: The yield of three batches meets the standard. Only when the yield is stable will mass production be launched—yield is the gate for samples.
Three batches of verification, everything clearly matched on one sheet
| Batch | What are you looking at? | Judgment |
|---|
| a batch | Run through | through |
| Second batch | reproduce | through |
| Three batches | Stable | through |
| Increase in volume | Meet the standard | Release |
Table reading method: Inspect batch by batch, only release after three batches, and retain ±3A margin for hardness in each batch.
Three batches are stable, mass production is stable.
Three batches steadily released in larger quantities, inspection and acceptance check these four items
| Project | Requirement | Judgment |
|---|
| Parameter | consistent | Meet the standard |
| Physical properties | Meet the standard | Meet the standard |
| Yield | Meet the standard | Meet the standard |
| Batch | Stable | Meet the standard |
Table reading: Check each sample item by item, observe the visible quantities, and compare three batches of data side by side.
The three batches are mass production inspections.
A batch goes straight into mass production, fluctuations have no chance to be exposed
Pitfall 1: Large release in batches. The first batch looks good, the second batch declines, complaints start coming in — the third batch is bound to fail.
Pitfall 2: Ignore fluctuations. Pitfall — always watch fluctuations.
Pitfall three: Not recording data. White effort—data must be recorded.
Parameters, yield, fluctuations — closely monitor before ramp-up
Three questions: what parameters, what physical properties, what yield. One verification: three batches actually measured — three questions and one verification, the supplier's details are clear.
Three batches of validation must come first: first complete the hardness, melt index, and appearance tests for three consecutive batches, then talk about mass production—three batches are the insurance for mass production.
Making sample retention a habit: retain samples for each batch, and re-test physical properties batch by batch. Before switching materials between batches, compare them first before scaling up—the batch is stable, and customer complaints are few.
One batch is good, three batches collapse: compare with a table
| Phenomenon | Reason | Countermeasure |
|---|
| overturn | A batch with increased volume | Go in three batches |
| Fluctuation | Do not focus on criticism | Monitor batch |
| Data missing | Do not record | Record data |
| Low yield | Parameters are messy | Lock parameters |
| Customer Complaint | Sharp increase in volume | Don't worry |
Once a batch is qualified, the volume is released, which is equivalent to gambling with the entire order. The whitening of soft rubber parts often doesn't appear until the third batch.
The samples go through three batches: the first piece is checked by hand-feel, the second piece is measured for physical properties, and the third piece evaluates yield rate. Only if all three batches are within ±3A will the mass production approval form be signed.
Keep 6mm thick samples from each batch, and measure Shore A at 23°C. If the hardness difference among the three batches exceeds ±3A, the customer will feel like it's 'two different batches'.
Sample rejection is mostly not because the material is bad, but because the drying and mold temperature were not set according to the material number. TPE absorbs moisture; bake at 80°C for 2-4 hours before molding for the data to be valid.
All three batches of samples passed, and the yield rate climbed above 95%, only then would we dare to start mass production. Skipping this step, the problems would come back tenfold on the production line.
Specimens go through three batches: the first batch is for feeling test by hand, the second batch tests physical properties, and the third batch checks yield rate. All three batches' Shore readings must be within ±3A to approve full-scale production; releasing full-scale production with only one batch qualified is equivalent to gambling with the entire order.
TPE should be dried at 80°C for 2-4 hours before being put on the machine; only then will the data be valid. If the moisture content exceeds 0.1%, silver streaks and bubbles appear on the surface. This drying step cannot be skipped, as whitening of soft rubber parts often only appears by the third batch.
Measure Shore A of each batch of 6mm thick test pieces at 23°C. If the hardness difference of three batches exceeds ±3A, the customer will feel like there are two different batches. Most of the time, test piece failure is not due to bad material but due to drying and mold temperature not being set according to the material number.
Only after three batches of samples all pass with a yield rate climbing above 95% will mass production be dared to start.
Skipping this step will result in problems being multiplied tenfold on the production line. For each batch, test pieces of 6mm thickness are measured for Shore A hardness at 23°C, and if the difference in hardness across three batches exceeds ±3A, the customer will feel like there are only two batches of goods.
Releasing large quantities once a batch passes inspection is equivalent to gambling with the entire order.
The whitening caused by the precipitation of soft rubber parts usually only appears in the third batch. For the samples, the first of three batches is tested by hand for feel, the second for physical properties, and the third for yield rate. Only when all three batches fall within ±3A will the mass production approval form be signed.
The sample goes through three batches: the first piece is checked by touch, the second piece is tested for physical properties, and the third piece is used to assess yield rate.
All three batches of Shore must be within ±3A before signing off for mass release; releasing mass with just one batch passing is like gambling with the entire order. TPE must be dried at 80°C for 2-4 hours before processing for the data to be valid.
TPE should be moisture-absorbed and baked at 80°C for 2-4 hours before running on the machine for the data to be valid. If the water content exceeds 0.1%, there will be silver streaks and bubbles on the surface. Only when all three batches of samples pass with a yield rate climbing above 95% can mass production proceed; skipping this step will cause problems to be returned tenfold on the production line.
Cologne customer case: Returns due to odor pile up in warehouse, matching substrate yield rate 98%
A modified material application factory in Guangzhou had TPE finished products returned by downstream customers due to odor, and the goods were piled up in the warehouse. Kolon cooperated to rematch the overmolding substrate and processing temperature, eliminating the odor, and mass production yield stabilized at 98%. Once the substrate matching was correct, the odor was stopped at the source — for odor issues, first check the substrate and oil.
Summary
The arrangement of TPE samples: three batches go first, observe stability, only after three batches are stable should we dare to go into mass production. Don't rush, the three batches are like a health check.
