供应商挑花眼，价格都差不多。选对了价格自然合理，判断力才是底牌。
价格差不多，比的是判断力
TPE 供应商是“判断活”：实力、服务、价格。结论先给：把实力和服务评到位，价格谈判自然有底——判断，是采购的底牌。
TPE供应商最大的坑：供应商实力没摸清，压下来的价换来了断供——判断，是采购的护身符。
供应商是采购的地基：选对，后续都顺。选错，处处踩坑——供应商，是采购的根基题。
供应商决定结果，为什么看实力
实力看车间：设备管理。实力，是供应商的底子。
服务看响应：交期售后。服务，是供应商的态度。
价格看体系：稳定合理。价格，是供应商的结果。
实力、服务、价格，怎么考
实力：车间仓库现场看。实力，是头一判据。
服务：响应速度实测。服务，是第二判据。
价格：对比后定。价格，是第三判据。

跑路、质量飘、响应慢：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 踩坑 | 只看价格 | 看实力 |
| 断供 | 服务差 | 测响应 |
| 翻车 | 口碑差 | 问同行 |
| 买贵 | 不会谈 | 对比价 |
| 客诉 | 选错人 | 走评估 |
选错供应商，再低的单价也会在客诉里吐回去。看实力、看响应、看口碑，比看报价单重要。
询价时同时发三家，记他们的响应速度和问题深度。三句话问不出工况的，直接降优先级。
留两家备选供应商，一家波动能立刻切换。主供占七成、备供占三成，议价和保供两头都稳。
只挑报价最低的那家，结果发错料、催不动、售后没人理。一年算下来，省的钱不够赔一次断供。
长期考核按月打分，交期、良率、响应都量化。供应商选对了，价格自然回到合理区间。

我们交付的，不只是一包料。
Suppliers are overwhelming, and the prices are all about the same. If you choose the right one, the price will naturally be reasonable; judgment is the real trump card.
The prices are roughly the same; what matters is judgment.
TPE suppliers are 'judged by life': strength, service, and price. Here's the conclusion first: if you rate strength and service properly, price negotiations will naturally have a baseline—judgment is the trump card in procurement.
The biggest pitfall with TPE suppliers: not understanding the supplier's strength, the price suppression leads to supply interruption — judgment is the buyer's protective charm.
Suppliers are the foundation of purchasing: if you choose correctly, everything goes smoothly. If you choose incorrectly, you encounter pitfalls everywhere—suppliers are the fundamental issue in purchasing.
The supplier decides the result, why look at strength
Strength looks at the workshop: equipment management. Strength is the foundation of the supplier.
Service is seen in response: delivery time and after-sales. Service is the attitude of the supplier.
Price depends on the system: stable and reasonable. Price is the result of the supplier.
Strength, service, price, how to evaluate
Strength: Look at the workshop and warehouse on-site. Strength is the primary criterion.
Service: Measured response speed. Service is the second criterion.
Price: determined after comparison. Price is the third criterion.
Supplier evaluation, a table clearly comparing
| Dimension | What are you looking at? | weight | Judgment |
|---|
| strength | Workshop | Tall | Must watch |
| Service | Response | middle | Must watch |
| Price | system | middle | Must watch |
| reputation | colleague | Low | Reference |
Table reading method: Arrange dimensions according to weight, and score capacity, quality control, and service first.
Judgment is the trump card in purchasing.
Choosing the right partner ensures long-term stability; evaluate these four items thoroughly
| Project | Requirement | Judgment |
|---|
| strength | Meet the standard | Verification |
| Service | Meet the standard | Verification |
| Price | reasonable | Verification |
| Qualification | Complete | Verification |
Table reading method: Evaluate each item individually, choose what's visible, and compare horizontally across more than three companies.
Judgment is the talisman for purchasing.
Only looking at the price without considering quality, you get what you pay for.
Pitfall 1: Only look at the price. The one with the lowest quote can't meet the production capacity, and during peak season, they'll run out of your goods first — you must check their capabilities.
Pitfall 2: Unexpected service issues. Supply cut off—service must be tested.
Pitfall three: Not asking about reputation. The trap — always ask about reputation.
Capacity, service, response — ask clearly before inspection
Three Questions: What strength, what service, what price. One Verification: On-site inspection and actual measurement - three questions and one verification, the supplier's details are clear.
Validation must come first: evaluate capacity, quality control, and after-sales service before discussing the price per ton—judgment is the buyer's trump card.
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.
Skipping town, inconsistent quality, slow response: compared on one chart
| Phenomenon | Reason | Countermeasure |
|---|
| fall into a trap | Only look at the price | Let's see your strength |
| cut off supply | Poor service | Test Response |
| Overturn | bad reputation | Ask colleagues |
| Bought at a high price | Can't talk | Comparison price |
| Customer Complaint | Chose the wrong person | Go assessment |
Choosing the wrong supplier, no matter how low the price, will be returned through customer complaints. Looking at strength, responsiveness, and reputation is more important than looking at the quotation.
When requesting quotes, send them to three companies at the same time, and note their response speed and the depth of their questions. If they can't ask about the working conditions in three sentences, directly lower their priority.
Keep two alternative suppliers, so that you can switch immediately if one fluctuates. The main supplier accounts for 70%, and the backup supplier accounts for 30%, keeping both negotiation and supply security stable.
Only chose the one with the lowest quote, but ended up with wrong materials shipped, unable to push them, and no after-sales support. Over a year, the money saved wasn't enough to cover even one supply disruption.
Long-term assessment is scored monthly, with delivery time, yield, and response all quantified. If the supplier is chosen correctly, prices naturally return to a reasonable range.
Even the lowest price will be returned in customer complaints if the wrong supplier is chosen.
When requesting quotes, send them to three companies at the same time and pay attention to their response speed and depth of their answers. Asking three questions may not reveal the operating conditions, so prioritize accordingly. It's more important to look at capability, responsiveness, and reputation than to focus on the quotation alone.
Keep two alternative main suppliers, with 70% from the main supplier and 30% from the backup. If one supplier fluctuates, switch immediately, choosing only the one with the lowest quote. As a result, the wrong materials were sent, there was no way to rush after-sales service, and no one cared. The savings of one year are not enough to compensate for a single supply disruption.
Long-term assessments score monthly, and delivery, yield, and responsiveness are all quantified. If the right supplier is chosen, the price naturally returns to a reasonable range. If you only pick the one with the lowest quote, the result is wrong materials being sent, urgent requests not being processed, and no one responding to after-sales issues.
Long-term assessment is quantified monthly for scoring, delivery, yield, and responsiveness.
If you choose the right supplier, the price will naturally return to a reasonable range. Just picking the one with the lowest quote can result in wrong materials being delivered, after-sales service being unresponsive, and by the end of the year, the money saved isn’t enough to compensate for a single supply disruption.
Choosing the wrong supplier means that no matter how low the price is, it will be returned through customer complaints.
Looking at capability, responsiveness, and reputation is more important than looking at the quotation. When inquiring, send requests to three companies at the same time and note their response speed and the depth of their answers. If three questions cannot reveal the working conditions, directly lower their priority.
Even the lowest price will be returned in customer complaints if the wrong supplier is chosen.
When requesting quotes, send them to three companies at the same time, record their response speed and depth of answers. If the three sentences cannot reveal the working conditions, lower the priority, keep two as backup options. Designate the main supplier to supply 70% and the backup to supply 30%, and switch immediately if one fluctuates.
Cologne customer case: High rework rate due to coating delamination, parameter adjustment reproduces the hand feel
A modified material application factory in Jiaxing experienced batch delamination of TPE overmolded parts, with a persistently high rework rate. Kolon cooperated to adjust injection molding parameters (mold temperature/material temperature/holding pressure), eliminating the delamination, and replicating the feel and rebound of the sample. The parameter window was locked down, stopping delamination at the source—the overmolding issue should first look at the substrate before considering the parameters.
Summary
When choosing a TPE supplier, first look at their strength, then test their service. If you choose correctly, the price will naturally be reasonable, and this judgment is the bottom line.
What we deliver is not just a package of materials.
