Mounting - also referred to as embedding - has several purposes. Mounting provides protection/support of the sample surface and edges, makes it easier to handle the sample, allows for several small samples in one mount and gives uniform sizes for clamping in a sample holder. To meet your mounting requirements both cold mounting and hot mounting systems are available.

Aka-Resin Phenolic SEM
Cold mounting has to be used for embedding of heat sensitive or fragile samples and when vacuum impregnation or infiltration of porous samples is required. Cold mounting is also often preferred, when only a few samples are prepared. We have the two main systems available, Epoxy and Acrylic, each offering different features and benefits. They both consist of two components that cure after being mixed together.
Hot mounting requires a mounting press, where the resin is processed at high pressure and temperature. Hot mounting provides very uniform samples in a short time, and depending on the resin used, quite different characteristics can be achieved. Our range of high performance hot mounting resins includes Epoxy, Melamine, Acrylic, Phenolic SEM and Phenolic.
We also have a wide range of embedding accessories. You find moulds, Aka-NoStick, protection caps, mixing kits and clips under accessories. These accessories help you obtain the best possible mounting result, which will save you time in the following preparation steps.

When should I use metallographic mounting?
You should use mounting when:
- your samples are small, irregular and difficult to hold.
- you need to protect the edge of your material.
- you need uniform, regular samples for clamping in a holder.
- you need to impregnate or infiltrate your samples (cold mounting).
What is the difference between hot and cold mounting?
Hot mounting requires a mounting press, a quite costly investment. On the other hand, hot mounting resins are generally less expensive than cold mounting resins. Therefore the number of samples to be mounted usually defines what to use. With few samples a day cold mounting is preferred, when many samples have to be prepared hot mounting is probably the better choice.
Are there reasons to select one mounting technique over the other
If the samples are porous or heat sensitive, then cold mounting in epoxy must be used. Cold mounting epoxy resins cure at low temperature and can be used for vacuum impregnation. With cold mounting you can also mount several samples at a time by mixing a larger amount, whereas hot mounting only allows for one, maybe two samples at a time.
