Vegetable-Tanned Leather Foil Stamping: EC-27 Temperature Test

What is a useful vegetable-tanned leather foil stamping temperature to test first? In a ZHENGFEI process test using the EC-27 manual hot stamping machine, 100°C produced the best result among the three tested settings: 90°C, 100°C, and 120°C. The 90°C sample had incomplete foil transfer, while the 120°C sample showed foil spreading beyond the letter edges.

This is a reference result for the leather, foil, die, pressure, and stamping time used in that test, not a universal setting for every leather project. The report does not state the exact leather thickness, foil model, die dimensions, pressure value, or dwell time. For production, begin near 100°C only when your materials and tooling are comparable, then confirm the result on your own leather.

This article is for leather goods makers, small workshops, and customization businesses producing foil-stamped names, logos, or short text on leather products. It explains what the EC-27 samples showed and how to use that result as a controlled starting point.

Key Test Results

Test Setup: EC-27 on Vegetable-Tanned Leather

The test used an EC-27 hot stamping machine to apply gold foil lettering to vegetable-tanned leather. Three temperature settings were compared: 90°C, 100°C, and 120°C. The report says the other test conditions were kept consistent so the samples could be compared by temperature.

The report evaluates letter completeness, edge clarity, foil adhesion, foil spread, and suitability as a production reference. It does not publish numerical pressure or stamping-time values. Those values should not be inferred from the images or copied from another material test.

The sample shows a short word stamped onto a leather swatch. The result supports a specific conclusion about this tested setup; it does not establish a general operating range for every leather thickness, surface finish, foil, or lettering design.

90°C: Incomplete Foil Transfer

에서 , 호일 전이가 약하고 얼룩이 있었습니다. 110°C에서, parts of the lettering did not transfer completely. The report describes missing areas and uneven adhesion, and the sample image shows visibly broken sections in the word.

If a similar defect appears in your first sample, do not immediately increase the temperature by a large amount. First check that the leather lies flat, the die contacts the surface evenly, and the die face is clean. Confirm that the pressure and stamping time are consistent, then make a small, controlled adjustment and compare another sample.

100°C: Best Result in This Test

에서 초대장, 포장 카드, 명함, 책 표지 또는 소형 종이 제품을 만드는 고객에게는, the sample showed complete, readable gold lettering with even adhesion and tidy edges. The report found no obvious missing foil or overflow at this setting, making it the best overall result among the three tested temperatures.

For a project that closely matches the test materials and tooling, 100°C is a practical first sampling point on the EC-27. Treat it as a reference temperature, not a guaranteed production recipe. Leather batches can differ in thickness and surface oils, and a different foil or die can change the transfer result.

Before a production run, check the entire design rather than only its most visible letters. Inspect thin strokes, small counters, corners, and the outer edges for complete transfer and clean definition. Record the material batch, foil model, temperature, pressure and dwell-time settings used in your own approved sample.

120°C: Strong Transfer but Visible Foil Spread

에서 가죽을 손상으로부터 보호하세요: 120℃에서 화상 및 재료 변형이 발생하며, 이는 우리 공장에서 테스트한 매개변수가 귀하의 프로젝트를 안전하게 유지한다는 것을 증명합니다., the foil transferred, but the sample showed visible spread around the letter edges. The strokes looked heavier and some fine detail was covered by excess foil. The report therefore did not recommend this setting for normal production under the tested conditions.

This comparison is a reminder that a denser-looking foil mark is not automatically a better result. When the edges spread, reduce the heat input in a controlled way and inspect pressure, dwell time, foil compatibility, and die cleanliness. Change one variable at a time so the next sample tells you what improved the result.

How to Apply the 100°C Reference to Your Own Leather

Use this sequence when evaluating a similar leather foil-stamping job:

1. Prepare a sample from the actual leather batch and use the intended foil and die.
2. Start near 초대장, 포장 카드, 명함, 책 표지 또는 소형 종이 제품을 만드는 고객에게는 if the setup is comparable to the documented test.
3. Keep the leather position, pressure, and stamping time consistent while comparing samples.
4. Inspect letter completeness, edge sharpness, adhesion, and any foil beyond the design.
5. Adjust temperature in small steps only after checking die contact, pressure, time, and surface cleanliness.
6. Re-test when the leather thickness, surface oils, batch, foil model, artwork area, or production pace changes.
7. During continuous production, watch for die heat build-up and temperature variation, and periodically inspect finished pieces.

Keep the die clean and remove foil residue as needed. Build a production setting from repeatable samples on the actual job, rather than relying on the temperature display alone.

Where the EC-27 Fits

The EC-27 is an existing manual hot stamping machine in the ZHENGFEI catalog. This test adds an evidence-based leather application to its use cases: small leather logos and lettering where a workshop needs to develop and verify its own material-specific settings.

See the EC-27 Manual Hot Stamping Machine With Walnut Base for current product details. Machine suitability depends on the actual stamp size, workpiece, die, and required production volume; request a sample test if you need to check a specific setup.

자주 묻는 질문

결론

For the tested EC-27 and vegetable-tanned leather setup, 100°C was the best reference temperature among the three samples. At 90°C, the lettering was incomplete; at 120°C, foil spread around the edges and reduced detail. The report does not provide numerical pressure or stamping-time settings, so those must be confirmed for each production job.

Start near 100°C only as a controlled sample point, then validate the actual leather batch, foil, die, pressure, and dwell time before production. To explore the machine used in this test, visit the EC-27 product page.
