询盘一句“TPE什么价”，报价差三倍。工况不写清，报价就是猜谜。
一句什么价差三倍，工况没写清
TPE 询价是“信息活”：工况、用量、标准。结论先给：询盘写清工况，报价才准——工况，是报价的尺子。
TPE询价最大的坑：工况一句不说，报价只能拍脑袋——工况，是报价的锚。
询价是采购基本功：会写询盘，报价才准。不会写，报价虚高——询价，是采购的入门课。
报价跟着工况走，为什么先给条件
工况决定牌号：温度、介质、负载。工况，是选型的依据。
用量决定单价：量大价低。用量，是报价的变量。
标准决定价格：食品级、阻燃贵。标准，是报价的系数。
工况、用量、标准，询盘写什么
工况：温度、介质、负载写清。工况清，选型准——工况，是头一要素。
用量：月用量、年用量。用量清，价格实——用量，是第二要素。
标准：食品级、阻燃、认证。标准清，报价对——标准，是第三要素。
询盘要素，一张表对照清楚
| 要素 | 写什么 | 影响 |
|---|
| 工况 | 温湿介质 | 选型 |
| 用量 | 月年量 | 价格 |
| 标准 | 认证等级 | 成本 |
| 交期 | 时间 | 排产 |
表格读法：要素写全，报价才准，硬度、基材、用量三样别漏。
要素齐，报价实。
报价准能落地，评估核这四项
| 项目 | 要求 | 判断 |
|---|
| 工况 | 写清 | 达标 |
| 用量 | 写清 | 达标 |
| 标准 | 写清 | 达标 |
| 报价 | 合理 | 达标 |
表格读法：询盘一项项核，报价看得见，使用温度和认证要求标上。
工况，是报价的尺子。
只问价格不说工况，报来也用不上
坑一：只问价格。一句多少钱一公斤，报价范围差出三成——工况必写。
坑二：用量不报。价格虚——用量必报。
坑三：标准不提。报价偏——标准必提。
硬度、耐温、用量——询价先写全
三问：什么工况、什么用量、什么标准。一验：报价对比实测——三问一验，供应商底细清楚。
工况验证要先行：先把硬度、基材、用量、使用温度写进询盘，再要报价——工况，是报价的锚。
留样要成习惯：每批留样，物性按批次复测。批次换料先对比再放量——批次稳，客诉少。
报不准、来回改、踩坑：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 报价虚 | 工况没说 | 写工况 |
| 价差大 | 用量没报 | 报用量 |
| 选型偏 | 标准没提 | 提标准 |
| 反复询 | 信息缺 | 写全 |
| 客诉 | 报价不准 | 写工况 |
询盘别只写“报个价”，要写“什么件、什么工况、什么基材”。月用量、认证要求一起列，供应商才不会拿通用牌号糊弄你。
Shore 区间写进询盘，别只写“软一点”。例：包胶手柄要 60A±3A、剥离力 1.0-2.0kN/m，范围一锁，三家报价才好比。
“按你们常规料报”最危险——常规料换你这个件，十有八九要重打样。工况不说清，报价越低，后面返工越贵。
报价虚高不是供应商黑心，是你没把用量和年量写进询盘。量大价低是常识，月用量到吨级，价格自然下一个台阶。
一次写全“工况+用量+标准”的询盘，三轮回信就能锁价。缺一项就来回补，光邮件就要耗掉两周交期。
询盘把Shore区间和剥离力一起写，别只写软一点。包胶手柄60A±3A、剥离力1.0-2.0kN/m，范围一锁三家报价才好比，不然拿通用牌号糊弄你。

给判断——什么件，用什么料。
Inquiry: One sentence asks, "TPE, what price?" means the quotation is three times higher. If you don't specify the operating conditions, the quotation is just a riddle.
One sentence: What is the price difference threefold? If you don't specify the operating conditions
TPE Inquiry is an "information activity": operating conditions, quantities, standards. First, give the conclusion: only by clearly stating the operating conditions in an inquiry can the quotation be accurate—the operating condition is the standard for quotation.
TPE the biggest pitfall in an inquiry: not mentioning the operating condition, the quotation can only be made on the head—the operating condition is the anchor of the quotation.
Inquiry is a basic procurement skill: only by writing an inquiry can the quotation be accurate. If you can't write, the quotation is inflated—inquiry is the introductory course in procurement.
Quotes follow operating conditions, why give conditions first ?
Operating conditions determine grade: temperature, medium, load. Operating conditions are the basis for selection.
Quantity determines unit price: large quantity, low price. Quantity is the variable in pricing.
Standard determines price: food-grade, flame retardant expensive. Standard is the quotation coefficient.
Operating conditions, usage, standards, what should be written in the inquiry
Operating conditions: clearly state temperature, medium, load. Clear operating conditions, accurate selection—operating condition is the first factor.
Usage: monthly usage, annual usage. Clear usage, real price—quantity is the second factor.
Standard: food-grade, flame retardant, certified. Clear standards, accurate quotations—standards are the third element.
Inquiry Elements, a single table for clear comparison
| Elements | WhatWrites | Impact |
|---|
| Working Conditions | Temperature and Humidity Medium | Selection |
| Usage | Monthly/Annual Volume | Price |
| Standard | Certification Grade | Cost |
| Delivery Schedule | Time | Production |
Table Reading: Write all elements for accurate quotation, and make sure hardness, base material, and quantity are all missing.
All elements are present, the quote is realistic.
Quote must be implemented, evaluate these four items
| Project | Requirement | Judgment |
|---|
| Working Condition | Clearly Write | Meet Standard |
| Usage | Clearly Write | Standard |
| Standard | Clearly Written | Compliant |
| Quoted | Reasonable | Compliant |
Table Reading: Inquiry is checked item by item, quotation is visible, usage temperature and certification requirements are marked.
Working conditions are the standard for quotations.
Only ask about price without specifying operating conditions, and even if you quote, you won't need to use it
Pit 1: Only ask about price. One sentence about how much per kilogram, quotation range differs by 30%—must specify operating conditions.
Pit 2: Do not report usage. Inflated price—must report usage.
Pit 3: No standard mentioned. Off-quotation — standards must be mentioned.
Hardness, temperature resistance, usage — Inquiry first states all
Three questions: What working conditions, what quantity, what standard. First inspection: Price comparison and actual testing—three questions and one inspection, supplier background is clear.
Operating condition verification must come first: first write hardness, substrate, quantity, and operating temperature into the inquiry list, then quote — operating condition is the anchor for the quotation.
Sample retention should be a habit: retain samples for each batch and retest physical properties by batch. Batch material changes should be compared first and then scaled up—batch stability and fewer customer complaints.
Inaccurate reporting, repeated revisions, falling into traps: compare with one table
| Phenomenon | Cause | Countermeasures |
|---|
| False quote | Operating condition not mentioned | Write working condition |
| Large price difference | Usage not reported | Quantity Reported |
| Selection Biased | Standard Not Mentioned | StandardIsStandard |
| Repeated Inquiry | Information Missing | Write Everything |
| Customer Complaint | Quote Inaccurate | Write Operating Conditions |
Inquiry Don't just write "quote a price"; write "What part, what operating condition, what kind of base material." List monthly usage and certification requirements together, so suppliers won't fool you with generic grades.
Shore Write the range in the inquiry, don't just say "softer." Example: The rubber handle should be 60A±3A, peel force 1.0-2.0kN/m, and the range locked in one range. Only then can the three companies' quotes be similar.
"Following your standard material quotation" is the most dangerous—if you trade standard material for this piece, you'll most likely have to redo the sample. If you don't specify the working conditions clearly, the lower the quote, the more expensive the rework later.
Inflated quotes aren't because the supplier is unruly; it's because you didn't include usage and annual quantities in the inquiry. High volume and low price are common sense. When monthly usage reaches ton-level, prices naturally go down.
Write the entire inquiry in one go of "operating conditions + usage + standard," and three rounds of replies can lock in the price. If any one is missing, you need to make up for it, and just the email alone can take two weeks to deliver time.
Inquiry should include both shore range and peel force, not just soft. Rubber handle 60A±3A, peel force 1.0-2.0kN/m; only by quoting three companies within one range can you compare; otherwise, they will fool you with a common grade.
Monthly and annual usage are included in the inquiry; high volume and low price are common knowledge. Monthly usage reaches the next level of price per ton; suppliers quoting shortage quantities are based on small batches, with quotes inflated by 30%.
One inquiry requires a full operating condition usage standard, and three rounds of replies can lock in the price
. If one item is missing, you need to make up for it back and forth. Just by emailing alone, you can take two weeks to lead the time. Certification requirements must be listed together so the supplier won't use the common grade to fool you.
The inflated quotation isn't because the supplier is unscrupulous; it's that you didn't include the usage and annual quantities in the inquiry
. Large volume, low price is common sense. From monthly usage to tonnage, the price naturally drops. Writing the full working condition usage standard in one go and three rounds of replies can lock in the price.
According to your regular material report, the most dangerous standard material is that if you replace this piece, eight or nine times out of ten, you'll need to redo the sample
. If you don't specify the working conditions, the lower the quote, the more expensive the rework later. Write the Shore range in the inquiry, don't just say soft. For example, the coated handle should be 60A±3A for peel force in the range of 1.0-2.0kN/m. Only three companies can compare.
Inquiry: Write the Shore range and peel force together, not just a softer one.
. Rubber handle 60A±3A peel force range: 1.0-2.0kN/m for one lock, three companies quote for comparison. For monthly usage to ton-level prices, the next step is shortage quantity, suppliers quote for small batches.
Cologne customer case: hardness drift and floating feel, small batch trial production after low-temperature bending
A modified material application factory in Hangzhou, TPE parts have batch hardness drift, hand feel fluctuates between soft and hard. Cologne cooperated with small-batch trial production for validation before scaling up, with stable hardness, passing low-temperature bending at -40°C in one go. Small-batch trial production locked batches before ramp-up—batch drift, first checking system stability.
Summary
The way to inquire from TPE: first write down the working conditions, then report the quantity. Only if the inquiry clearly states the working conditions will the quote be accurate; working conditions are the anchor.
Explain who we are in three lines:
Modify performance—modified thermoplastic elastomers, modified nylons (PA6 / PA66 / PA46 / PA11 / PA12 / PA6T / PA9T and nylon alloys), modified PPO / PPS;
Have sources—nylon resins from major chemical giants, secondary-grade materials, and bulk materials in stock;
Provide judgment—what part, what material to use.
