Is Your Old Press a Ticking Time Bomb? The Case for Retrofitting Safety

The Retrofit Nightmare

For years, the answer was a painful one. You could try to engineer a custom solution—a messy, expensive puzzle of sourcing individual valves, designing new circuits, and spending weeks on installation and validation with no guarantee of certification. Or, you could bite the bullet and invest in a brand-new machine, scrapping a perfectly good piece of equipment.

This is the retrofit nightmare: a choice between high costs, long downtime, and uncertain outcomes.

One Block, Total Confidence

What if you could bypass that nightmare entirely? What if upgrading your press was as simple as installing a single, pre-engineered module?

That’s the exact problem the Bosch Rexroth IH04N Retrofit Manifold was designed to solve. It’s not a collection of parts; it’s a complete, integrated safety solution in one block, built specifically for existing presses.

It consolidates the three most critical safety functions older machines often lack:

• Protection against unintended ram movement (e.g., gravity fall).
• A reliable, monitored stop of any dangerous motion.
• Prevention of accidental machine start-up.

Turning a Project into a Procedure

By using a standardized module like the IH04N, you transform a massive engineering project into a straightforward implementation procedure.

• The Problem: Your press fails a safety audit due to outdated controls.
• The Old Solution: Weeks of custom design, sourcing, and testing.
• The New Solution: Install the IH04N module.

Operators who have made the switch report cutting their upgrade and installation time by over 70%. The engineering costs are virtually eliminated because the solution is already designed and documented.
