In the process of metallographic sample preparation, inlay is a relatively important step. So the question arises, do you know which samples need to be embedded? Today, the editor of Kemai specifically organized this issue, and the details are as follows:


1. The sample is relatively small


2. The sample has a complex shape (making it difficult to retrieve)


3. Need to protect edges


4. Case-hardening layer


5. Coating (conical part)


6. The sample is porous or has cracks


7. Powder alloy


8. Ceramics


9. Petrographic samples


10. Failure Analysis


Generally, samples that encounter the above situations need to be embedded first before they can be ground and polished, so it is also necessary to have a handy metallographic embedding machine. Kemai editor recommends the equipment required for hot embossing: single cylinder fully automatic hot embossing machine METPRESS A

METPRESS A single cylinder fully automatic hot pressing inlay machine can simultaneously embed 2 samples, can be heated to 200 ℃, and can be pressurized to 350 bar. The sample preparation speed is fast, programmable, and is very suitable for continuous and repeated preparation of standard sample blocks.


The uniqueness of METPRESS A single cylinder fully automatic hot pressing inlay machine:

★ Turn on the power to preheat at 30-75 ℃, saving sample preparation time and improving work efficiency.


The display screen displays the current temperature and pressure in real-time, and the embedding process is clear at a glance.


★ The cooling modes are fast, medium, and slow, fully considering the diversity of preparation materials.


When the cooling is insufficient, there is a reminder function to continue cooling to prevent preparation errors and improve the safety of operation.


★ Sliding cover opening and closing, labor-saving and convenient.



After talking about the hot press inlay machine required for inlay, the inlay consumables should go on stage as expected! After all, just having equipment without consumables is definitely not enough! Usually, the consumables required for hot inlay include QMAXIS hot pressing inlay powder, QMAXIS inlay auxiliary consumables, etc.


The original imported QMAXIS hot pressing inlay powder from the United States is suitable for hot pressing inlay of materials that are not sensitive to temperature and pressure. It has good edge protection effect and is suitable for continuous batch sample preparation. Hot pressed inlay powders with different compositions, hardness, and colors can meet the inlay needs of most materials.
