小批量试料没做透，量产一上全是问题。试料就是量产的预演，两头一起验。
小批没走透，量产全是坑
TPE 打样是“双验关”：料验、模具验、工艺验。结论先给：小批量试料，模具工艺一起验——两头，是打样的卷子。
TPE打样最大的坑：只验料不调工艺，一小批过了放量就翻车——两头，是打样的完整卷。
打样是质量关：样打对了，量产才稳。打样马虎，量产返工——打样，是量产的预演。
小批验证再放量，为什么不能省
打样是小批验证：料、模具、工艺一起试。小批，是放量的预演。
打样要按流程：先小批，再放量。跳过小批，风险大——流程，是打样的路线。
打样要留数据：参数、良率都记录。数据，是打样的答卷。
备料、试模、验收，流程怎么走
备料：按配方备料，烘料到位。备料，是打样的起点。
试模：模具上机试，参数初调。试模，是打样的核心。
验收：全项验，良率算。验收，是打样的闸门。

TPE打样的流程，小批先走，两头再验，小批量试料模具工艺一起验，两头是卷子。
The small batch trial material wasn't thoroughly tested, so when mass production starts, there are all kinds of problems. Trial production is essentially a rehearsal for mass production, testing both ends simultaneously.
The small batch didn't go through completely, and mass production is full of pitfalls.
TPE prototyping involves 'double checks': material inspection, mold inspection, and process inspection. Conclusion first: for small batch trial materials, inspect the mold and process together — both ends, this is the gist of prototyping.
The biggest pitfall of TPE prototyping: only checking the materials without adjusting the process; a small batch might pass, but mass production will fail—this is the complete cycle of prototyping.
Sampling is a quality checkpoint: if the sample is done correctly, mass production will be stable. If the sampling is sloppy, mass production will require rework—sampling is a rehearsal for mass production.
Small-batch verification before full-scale production, why can't it be skipped
Proofing is small-batch verification: material, mold, and process are tested together. A small batch is a rehearsal for mass production.
Proofing should follow the process: first small batches, then large scale. Skipping small batches carries high risks—the process is the route for proofing.
Sampling requires keeping data: parameters and yield rates should all be recorded. Data is the answer sheet of sampling.
Material preparation, mold testing, acceptance inspection—what is the process?
Preparing materials: Prepare materials according to the formula and ensure the ingredients are dried properly. Preparing materials is the starting point of sampling.
Trial molding: Test the mold on the machine and make initial adjustments to the parameters. Trial molding is the core of prototyping.
Acceptance: Inspect all items and calculate the yield rate. Acceptance is the gate for proofing.
Proofing process, one sheet clearly shows the comparison
| Step | What are you doing? | Judgment |
|---|
| Prepare materials | Formula baking material | Must do |
| Trial mold | Parameter Adjustment | Must do |
| Detection | Full measurement | Must do |
| Increase in volume | Yield meets the standard | Must do |
How to read the table: go through each step one by one, without skipping anything; all three rounds of material, mold, and process must be completed.
Follow the entire process, and the proofing will be stable.
Only increase the volume after thorough testing, and check these four items during acceptance
| Project | Requirement | Judgment |
|---|
| Material properties | Meet the standard | Verification |
| Yield | Meet the standard | Verification |
| Size | Meet the standard | Verification |
| Batch | Lock | Verification |
How to read the table: Check each proof item one by one, look for visible volume, and keep comparisons between samples and mass-produced items.
Both ends are the sample sheets.
Skip the small batch and go straight to production, paying the tuition through mass production
Pitfall 1: Skipping small batches. Going straight to machine mass production will expose all deviations once the mold temperature is adjusted — small batches must be done.
Pitfall 2: Only inspecting the material. Increased volume leads to failure—inspect mold and process together.
Pitfall three: Not keeping data. Rework — data must be kept.
Mold, Material, Process — Ask Clearly Before Testing the Material
Three questions: what formula, what mold, what yield. One test: small batch trial production measurement — three questions and one test, the supplier's details are clear.
Double verification must come first: first, run the three-piece set of materials, molds, and processes in small batches, and then talk about scaling up—both ends, this is the complete cycle of prototyping.
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.
Excessive sample production collapse: Refer to a table
| Phenomenon | Reason | Countermeasure |
|---|
| overturn | Small batch jump | Follow procedures |
| Low yield | Poor craftsmanship | Adjust parameters |
| Size deviation | Poor mold | Repair molds |
| Data missing | No sample retained | Keep data |
| Customer complaint | Print Sample Pine | Set standards |
Skipping small batches and going straight to large-scale production, samples perform perfectly, while mass production drags. Samples are cherry-picked, mass production is the truth test, saving on small batches will cost in mass production.
Don't skip any of the four steps in prototyping: preparing and drying materials, trial molding and parameter adjustment, full inspection, and mass production only after yield standards are met. Skipping a step in mass production will lead to failure, so don't try to save time by skipping procedures.
The sample production cycle depends on inventory: for items in stock, samples can be produced in three days; for items requiring R&D, formulas take a week to adjust; if neither is available, don't wait.
Samples can be produced in two weeks, but urgent orders delayed by one or two months cannot catch up; the speed of sample production depends on capability.
Proofing is a 'rehearsal' for mass production, where the mold and process are tested together. Even if the material is fine, if the process is not followed, good material can still produce bad results, and if the testing method is wrong, the conclusion will be misleading.
A small batch of 200 units with stable yield and all physical properties meeting standards will prevent panic when scaling up. The first article should be checked again against the small batch standards before mass production—don't ramp up production immediately after passing the small batch.
Leave two weeks for sample production; urgent orders that take one or two months can't catch up. Samples are selected, but mass production is the real test. For small batches, after producing 500 units for trial, we need to evaluate appearance, feel, and durability before discussing scaling up.
The material is fine, but the process wasn't followed. Even with good material, bad results were produced during testing. If any of the drying temperature, mold temperature, or injection speed is incorrect, the trial mold data will be off. For sample production, the speed of the machine operator is more important than the sample itself.
The material is fine, but the process wasn't followed properly; even with good material, bad results were produced. The testing method was incorrect, causing the conclusion to deviate.
Urgent orders that need samples in two weeks but are delayed for one or two months can't be caught up; the speed of making samples depends on capability, and speed is more important than the operators.
Samples are handpicked; mass production is the real truth-revealer. Small batches save, but mass production makes up for it.
If you try to jump straight to mass production, you'll fail. Don't try to speed things up or skip steps. Samples promised in two weeks will fall behind if urgent orders of one or two months pile up. Your ability is tested by the speed of prototyping.
Cologne Customer Case: Frequent Batch Color Difference Complaints, System Change Delivered in 7 Days
A modified material application factory in Changzhou had obvious batch color differences in TPE samples, and finished products were frequently complained about. Kolon coordinated the change of system and grade (from SEBS-based to TPV-based), stabilizing the color difference and reducing the delivery cycle to within 7 days. With the system changed, batch issues are cut off at the source — for color difference problems, first look at system stability.
Summary
The TPE prototyping process: start with a small batch first, then inspect both ends. For small batch trial materials, the mold and process are inspected together, and both ends are rolls.
