TPE配色最大的坑：特殊色粉一克比一公斤料还贵，乱选直接超预算——色粉，是成本的隐藏账。
配色是成本关：色粉选对，成本可控。选错，成本翻倍——配色，是采购的成本题。
色粉是成本大头，为什么先算账
色粉贵过料：特殊色成本高。色粉，是配色的价格锚。
打样费工：打样按次计。打样，是配色的时间账。
批次难控：色差返工。批次，是配色的质量账。
色粉、打样、批次，钱花在哪
色粉：选普通色省钱。色粉，是头一变量。
打样：打样次数控制。打样，是第二变量。
批次：色差提前防。批次，是第三变量。

配色超支，多半不是料贵，是色粉和打样次数失控。深色、鲜艳色的色粉，一斤能比本色料贵几倍。
打样前先定三条：目标色卡、ΔE≤1.5、打样次数封顶。三次打不出来，先回配方，别硬磨。
色粉占比看着小，深色件能占到成本一成。常用色建色库存档，下次直接调，省掉重复打样。
每次换批次色粉都重打样，光打样费就吃掉利润。颜色不稳，退货和返工一起找上门。

TPE配色成本的算法，色粉先选，打样再控，色粉贵过料配色别乱来，色粉是锚。
The color scheme looks simple, but the calculation is shocking: the pigment is more expensive than the material. Without planning the color scheme, all the money is spent on invisible parts.
Pastels are more expensive than materials, and the color matching has no plan
TPE color matching is a 'costly task': color powder, sampling, batch. Here's the conclusion first: color powder is more expensive than the material, so don't mess up the color matching—color powder is the main cost in color matching.
The biggest pitfall of TPE color matching: special color powder costs more per gram than a kilogram of material, and choosing randomly can directly exceed the budget — color powder is a hidden cost.
Color matching is a cost issue: if you choose the right pigment, the cost is controllable. If you choose incorrectly, the cost doubles—color matching is a cost problem for procurement.
Pastel is the biggest cost, so why calculate the accounts first?
Pigment is more expensive than material: Special colors are costly. Pigment is the price anchor for color matching.
Sample Making Labor Fee: Sampling is charged per time. Sampling is the time account for color matching.
Batch control is difficult: color difference requires rework. A batch is the quality account of color matching.
Pastels, proofs, batches, where is the money being spent
Colored powder: choose ordinary colors to save money. Colored powder is the primary variable.
Proofing: Control the number of proofing times. Proofing is the second variable.
Batch: Preemptive color difference prevention. Batch is the third variable.
Color matching costs, clearly compared in one table
| Pastel | Cost | Proofing | Batch |
|---|
| Ordinary | Low | few | Stable |
| Pearlescent | Tall | many | Difficult |
| fluorescence | Tall | many | Difficult |
Table reading: The cost of special colors has increased several times, titanium dioxide and pearlescent powder are calculated by the gram.
Pastel is the price anchor for color matching.
Make sure the colors are set without going over budget, check these four items
| Project | Requirement | Judgment |
|---|
| Pastel | Suitable | Meet the standard |
| Proofing | Control times | Meet the standard |
| Color difference | ΔE<1 | Meet the standard |
| Cost | Budget | Meet the standard |
How to read the table: Check costs item by item, the budget is visible, and mark the proportion of pigments and the number of proofs.
Colored powder is the hidden account of costs.
Special colors are randomly sampled without limit, and the costs are all floating
Pitfall 1: Randomly choosing special colors. A pearlescent white sample was made eight times, and the cost of color powder could buy half a ton of material—the color powder must be chosen correctly.
Pitfall 2: Unlimited proofs. It costs money — proofing must be controlled.
Pitfall three: Not checking color differences. Rework—color differences must be checked.
Pastels, proofing, mass production — calculate clearly before color matching
Three questions: what color powder, what proofing, what color difference. One verification: actual cost measurement – with three questions and one verification, the supplier's details are clear.
Pigment verification must come first: first fix the pigment grade, addition ratio, and number of sample trials, then calculate the color matching cost—pigments are the main cost in color matching.
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.
Color value, color difference, repeated proofs: compared in a table
| Phenomenon | Reason | Countermeasure |
|---|
| Overbudget | Random selection of pastels | Choose the right pigment |
| Costly | Unlimited Proofing | Number of controls |
| Return to work | Color difference not noticeable | Monitor color difference |
| Fluctuation | Batch disorder | Lock Batch |
| Customer complaint | Cost overrun | Follow procedures |
Color matching budget overruns are mostly not due to expensive raw materials, but rather uncontrolled color powders and proofing iterations. Dark and bright color powders can cost several times more per pound than the base material.
Set three rules before proofing: target color swatch, ΔE≤1.5, and a cap on the number of proofs. If it can't be achieved in three tries, go back to the formula first; don't force it.
The proportion of color powder looks small, but dark pieces can account for about 10% of the cost. Keep a stock of commonly used colors for future color mixing, so next time you can adjust directly and avoid repeated sampling.
Every time we change the batch of toner, we have to redo the samples, and the sampling cost alone eats into the profits. When the color is unstable, returns and rework come together.
Color difference lock ΔE≤1.5, commonly used colors in the color library, can reduce color matching costs by 20%. When colors are stable, customer complaints naturally decrease.
Overspending on color matching is mostly not because the materials are expensive, but because the pigments and the number of proofing rounds are out of control.
Dark and bright colored powder costs several times more per pound than natural color material. Before sampling, the color card should be fixed with ΔE≤1.5, with a maximum of three attempts. If it cannot be achieved, return to the formulation first.
Common colors are stored in color preparation files for direct sample adjustment next time. Each time a batch is changed, remaking samples consumes the profit on just the sample fee, and the proportion of color powder in dark pieces can reach about 10% of the cost. With a color difference ΔE≤1.5, customer complaints naturally decrease.
Every time a new batch of toner is changed, a full sample test must be redone, and the cost of the samples eats into the profit. When the color is unstable, returns and rework come together. Color differences are locked at ΔE≤1.5, and the color library accumulates commonly used colors, which can reduce matching costs by 20%.
Color difference lock ΔE≤1.5, commonly used colors in the color library sediment, the color matching cost can be reduced by 20%
When the color is stable, customer complaints naturally decrease. Every time we change batches of color powder, we have to redo the samples, and just the sampling cost eats into the profit. If the color is unstable, returns and rework come knocking together.
Overspending on color matching is mostly not because the materials are expensive, but because the pigments and the number of proofing rounds are out of control.
A pound of dark bright-colored pigment can be several times more expensive than the base material. Before sampling, first set three target color swatches with ΔE ≤ 1.5. Limit the number of sampling attempts to three. If you can't achieve it, go back to the formulation instead of forcing it.
Overspending on color matching is mostly not because the materials are expensive, but because the pigments and the number of proofing rounds are out of control.
A pound of dark bright-colored powder is several times more expensive than natural-colored material. Before proofing, the color card ΔE should be ≤1.5, with a maximum of three attempts. If it cannot be achieved after three tries, return to the commonly used formula, record the color development in stock, and adjust the sample directly next time.
Cologne customer case: insufficient rebound does not meet the standard, adjusting parameters causes odor during acceptance
A modified material application factory in Beijing had issues with TPE parts not rebounding adequately, and the functional parts failed to meet performance standards. Kolon cooperated to adjust the injection molding parameters (mold temperature/material temperature/holding pressure), and the rebound recovered. The odor level met the client's acceptance standards. The parameter window was locked, stabilizing the rebound from the source—when there is a rebound issue, first look at the parameters, then the formulation.
Summary
The cost calculation for TPE color matching: first choose the color powder, then control after sample making. If the color powder is more expensive than the material, don't mix colors randomly; the color powder is the anchor.
