Modernizing Injection Molding Equipment for Long-Term Reliability

Replacing injection molding equipment is a major capital expense. In many cases, upgrading and modernizing existing machines can significantly improve performance, efficiency, and reliability at a fraction of the cost of full replacement.

DPSS provides retrofit and upgrade services that extend equipment life, improve system performance, and support continued production, especially for legacy and out-of-support machines.

Controller Retrofits

Outdated control systems can limit performance and make troubleshooting more difficult. DPSS provides controller retrofit services designed to:

  • Improve machine reliability

  • Enhance system diagnostics

  • Modernize aging controls

  • Restore long-term serviceability

Upgrading controls allows older machines to remain viable and easier to maintain in modern production environments.

Servo Pump System Upgrades

Hydraulic systems are central to injection molding performance. Converting conventional pump systems to servo-driven systems can offer:

  • Improved energy efficiency

  • More consistent machine performance

  • Reduced system wear

  • Enhanced process control

DPSS evaluates existing systems and implements servo upgrades tailored to your machine and production requirements.

Electrical & Hydraulic System Modernization

In addition to controller and servo upgrades, DPSS performs targeted system improvements including:

  • Electrical component upgrades

  • Wiring and system refinements

  • Hydraulic system updates

  • Replacement of obsolete components

Modernizing critical systems improves long-term reliability and simplifies future maintenance.

Upgrading Legacy & Out-of-Support Equipment

Many injection molding machines remain productive long after OEM support has ended. DPSS specializes in supporting and upgrading legacy equipment, including machines that are no longer serviced by the original manufacturer.

By modernizing key systems, manufacturers can protect valuable capital assets while maintaining dependable production.
