Expert Troubleshooting & Repair for Injection Molding Equipment
When injection molding equipment goes down, production stops. DPSS provides experienced, technically sound repair services for injection molding machines and auxiliary plastics equipment across North America.
With deep expertise in electrical and hydraulic systems, we diagnose problems accurately, perform effective repairs, and help prevent repeat failures through thorough root cause analysis.
Expert Troubleshooting & Repair
Comprehensive Machine Troubleshooting
Injection molding machines are complex systems that require specialized knowledge to service properly. DPSS provides advanced troubleshooting for:
Electrical system failures
Hydraulic system issues
Control system faults
Servo system problems
Machine communication errors
Intermittent or recurring performance issues
We work directly with plant maintenance teams to isolate faults efficiently and restore safe, reliable operation.
Electrical & Hydraulic Expertise
Many injection molding failures originate in electrical or hydraulic systems. DPSS has extensive hands-on experience diagnosing:
Wiring and connection faults
Sensor and component faults
Hydraulic leaks and pressure issues
Pump and valve malfunctions
Electrical print reading and diagnostics
Accurate troubleshooting minimizes unnecessary part replacement and reduces extended downtime.
Engel Machine Repair Specialists
DPSS has significant experience servicing Engel injection molding machines, including legacy models and equipment that may no longer be supported by the OEM.
Our familiarity with Engel controls, hydraulic systems, and overall machine architecture allows us to efficiently diagnose issues and restore reliable operation. We understand the nuances of Engel systems and are frequently called upon to support aging equipment that remains critical to production.
In addition to Engel machines, DPSS services a wide range of major injection molding manufacturers, including:
HPM

Industrial chillers
Thermolators
We evaluate the entire production system — electrical, hydraulic, and mechanical — to ensure all interconnected equipment is operating reliably.
Root Cause Analysis
At DPSS, our repair work goes beyond restoring operation. Every service call we make includes careful evaluation of why the issue occurred and what steps can help prevent it from happening again.
By identifying contributing factors, whether they’re electrical, hydraulic, mechanical, or operational, we help your facility strengthen its reliability and reduce future disruptions.
