High Velocity Compaction Means High Performance Parts

Hydropulsor's high velocity compaction (HVC) presses have taken powder compaction to the next level. Today, because of our revolutionary high velocity impact design, higher levels of density can be obtained which mean higher performance parts are now within your economical reach.

Although similar to conventional powder compaction presses in many ways, Hydropulsor presses use a high speed punch motion to achieve higher densities, typically using the same powder materials you are familiar with. Powder filling, compaction and ejection of green compacts are similar to uni-axle compaction presses. Our latest generation of presses can provide densities close to the theoretical maximum for a powder mixture

When the best gets better!

Hydropulsor entered the powder metal market with industry leading equipment capable of obtaining unmatched levels of compaction in standard production materials. Today, we are producing our third generation of HVC equipment. These new production-friendly machines consist of three modules : the base unit, the impact unit and the tool adaptor. The impact unit can easily be dismounted from the base unit and is exchangeable. The tool adaptor can be readily moved outside the machine for quick tool change and/or service. We offer three frame sizes: small, medium and large. For flexibility, our large frame can accommodate two sizes of impact units, which permits higher press tonnages without a larger press.

High Velocity Compaction vs. Conventional Compaction: What is the Same? What is Different?

What´s the Same?	What´s Different
• Typically uses the same powder materials you are familiar with.	• Higher green densities in a single compaction step.
• Tooling is similar to conventional press tooling and can be supplied by your current tooling manufacturer. The main difference is material selection and a more robust punch base construction.	• Employs impact force instead of static compaction.

• Hydropulsor presses feature advanced controls found on the most modern conventional powder presses such as: automatic filling height correction for each press axis, SPC logging and closed-loop control circuits for all controlled axes.	• Superior control . Multiple impacts can be used to precisely increase density.
• Same press is used for sizing and compaction.	• Superior uniformity . HVC parts have higher uniform densities throughout so closer final part tolerances are achieved.
	• Hydropulsor presses are categorized by impact energy not tons.
	• Large parts , up to 5 kgs (11 lbs.) can be compacted.
	• Lower ejection force required due to low "spring back".
