Electrical & Hydraulic Controls for Rubber Processing Equipment
West Coast Rubber Machinery updates, repairs, and replaces electrical and hydraulic control systems for rubber mills, hydraulic presses, and rubber mixers. Services include VFD (variable frequency drive) installation, PLC upgrades, operator control panel replacement, pressure transducer updates, temperature control modernization, hydraulic valve service, and manifold repair. WCRM also offers refurbished electrical and hydraulic control assemblies for equipment requiring cost-effective replacement.
Electrical Control Updates & Upgrades
Many rubber processing machines in current production are operating with electrical controls that have aged considerably. Relay-based logic, obsolete operator panels, and dated safety circuits are common in equipment that is otherwise mechanically sound. Updating the controls is often the most practical way to extend the useful life of a good machine and bring it into compliance with current safety expectations.
VFD (Variable Frequency Drive) Installation
Electronic speed control replacing fixed-speed drive systems. Allows roll or motor speed to be adjusted to match compound requirements; provides soft-start to reduce mechanical stress during startup; improves energy efficiency. Evaluated as part of the full drive arrangement—not treated as a standalone electrical upgrade.
PLC Upgrades
Replacement of relay-based or obsolete control logic with programmable logic controllers for more reliable, maintainable, and capable cycle control.
Operator Control Station Replacement
New front and rear operator panels with current-standard Start, Stop, Emergency Stop, Jog/Reverse, and speed control interfaces. Installed and tested as part of rebuild or as standalone service.
Temperature Control Modernization
Replacement of outdated thermocouple controllers and temperature regulators with current digital systems for improved setpoint accuracy and process repeatability on heated presses and platens.
Safety Circuit Updates
Emergency stop systems, overhead rocker bar replacement, door interlocks, and other safety-related electrical components updated to current standards. OSHA stopping-distance testing and certification where applicable.
Refurbished Control Assemblies
Refurbished electrical control panels and assemblies available for mills and presses where a complete new panel is not required.
Hydraulic Control System Service
Hydraulic control systems on rubber presses and mixers include directional valves, pressure relief valves, proportional valves, pressure transducers, and manifold assemblies. As these components age, they can cause pressure inconsistency, slow or erratic press movement, leakage, and cycle timing problems that affect part quality. WCRM services hydraulic control systems as part of press refurbishments and as standalone repair work.
Valve Replacement & Service
Directional control valves, pressure relief valves, check valves, and proportional valves inspected, serviced, or replaced.
Pressure Transducer Updates
Replacement of outdated or failed pressure transducers with current sensors compatible with modern control interfaces.
Manifold Inspection & Repair
Hydraulic manifold inspection for internal leakage, cracking, and seal condition. Repair or replacement as required.
Hydraulic Power Unit Service
Pump inspection and replacement, reservoir cleaning, filter system service, and fluid analysis as part of press refurbishment or standalone service.
Refurbished Hydraulic Control Assemblies
Refurbished hydraulic control components available where new replacement is not required.
The Right Time to Address Controls
A rebuild provides the most practical opportunity to address controls. When a mill or press is already disassembled for mechanical restoration, integrating control updates at the same time eliminates the need for a separate service window and ensures the electrical and hydraulic systems are matched to the restored mechanical components. Installing a VFD or replacing an operator panel on a machine that has not been fully inspected risks masking underlying mechanical issues the controls cannot fix.

Engineering FAQ
Can a VFD be added to a mill that currently runs at fixed speed?
In many cases, yes. Feasibility depends on the existing drive motor type, electrical infrastructure, and the condition of the mechanical drive components. WCRM evaluates the full drive arrangement when discussing VFD retrofits rather than treating it as a standalone electrical swap.
Do you offer emergency control repairs?
Contact us directly for urgent situations. We will work to assess the problem and determine the fastest path to getting your equipment back in service.
Can you supply controls for equipment we did not originally purchase from WCRM?
Yes. We service and update controls on rubber processing equipment from most manufacturers.
What information helps with a controls quote?
Equipment type and make, current control system description (relay-based, existing PLC platform, operator panel configuration), the specific problem or upgrade being addressed, and photos of the current control arrangement are the most useful starting points.
Discuss Your Controls Requirements
Whether you need an emergency repair, a VFD installation, or a full control system update as part of a rebuild, tell us what you have and what you need and we will work out the right approach.
