Electric Isostatic Press for Precision Applications
Hench's Electric Isostatic Press series delivers uniform pressure distribution and precise control for laboratory and industrial sample preparation. Because the force is applied evenly around the sample, isostatic pressing avoids the density gradients that single-axis compaction can leave behind.
The range covers two families: the fully automatic desktop HAP-J series and the HDP-J electric press. Both are driven electrically, so pressure is set from the control panel instead of by hand pumping.
HAP-J and HDP-J Compared
| Model | Force range | Format | Typical use |
|---|---|---|---|
| HAP-J | 20 / 30 / 40 / 60 / 100 ton | Fully automatic isostatic desktop press | Routine laboratory compaction where repeatability matters |
| HDP-J | 20 / 40 / 60 ton | Isostatic electric press | General isostatic sample preparation |
Why choose isostatic pressing
Uniaxial pressing pushes powder against a single moving face, so friction with the die wall can leave the pellet denser at the top than at the bottom. Isostatic pressing applies pressure uniformly, which produces a more even green body and reduces the risk of lamination and internal cracks.
- More uniform density through the sample
- Lower risk of cracking during ejection
- Pressure set on the panel, so results are repeatable between operators
- Suitable for powders that do not compact well in a single-axis die
Control and operation
Both families are electric, which removes the manual pumping step and makes the pressing cycle consistent. Choose the force range from the pellet diameter you need to press and the hardness of the material: the 20-ton entry models cover routine laboratory work, while the 60 and 100-ton configurations are intended for larger discs and denser powders.
Confirm the power supply, the working pressure you intend to use and the expected pellet size with the Hench team before ordering, so the press is configured for the destination laboratory.
Request an isostatic press quotation
Send the sample material, target pellet diameter, required force and your electrical supply. Hench will confirm whether the HAP-J or HDP-J configuration fits the application. Contact us to request a quotation.
What to confirm before ordering
- Force range. The entry 20-ton configurations suit routine laboratory compaction; 60-ton and 100-ton machines are intended for larger discs and denser powders.
- Pellet format. Tell us the finished diameter or shape, because it determines both the die and the force required to reach your target pressure.
- Electrical supply. Because these are electric presses, the supply at the destination laboratory must match the configuration ordered.
- Bench or floor space. The desktop HAP-J format is designed to sit on a bench; confirm the footprint and the weight of the machine before installation.
Support
Hench supplies an introductory operation video before shipment and remote support for routine questions, with engineer visits for installation, testing and staff training where the order and destination require it. Confirm the service scope for your project with the sales team.
