Overview
Pascal's QMC (quick mold change) control system supplies and switches the hydraulic and air circuits used for quick mold change on injection molding machines. It includes control units, non-leak valve units, air solenoid valve units and piping materials, sized from small to large machines. The HCM control unit is built for easy maintenance on medium and large machines.
Key Features
- Control units by machine size
- HCS suits small and medium machines, HCM and HCP suit medium and large machines, and HCE is an electric motor drive unit for large machines.
- Block-type valve unit
- On the HCM, independent circuit valves are combined into one block valve, which improves maintainability.
- Steel tank
- The HCM uses a steel tank that stands up to impact and heat.
- Oil return at air bleeding
- The HCM returns oil to the tank when air is bled from the circuit.
- Filter regulator as standard
- The HCM comes with an air filter regulator.
- Non-leak valve units
- VSE and VSL solenoid-operated hydraulic selector valves; VSL is for large-volume oil circuits.
- Air solenoid valve units
- GSC, GSF and GSG combine a solenoid valve with a pressure switch.
Product Line / Models
Pascal's control system is built from these units:
- HCS control unit – Air-driven, solenoid-operated hydraulic unit for small and medium injection molding machines; 1 to 4 hydraulic circuits.
- HCM control unit – Air-driven, solenoid-operated hydraulic unit for medium and large machines, made up of a Pascal pump, non-leak valve unit and air solenoid valve; 1 to 4 hydraulic circuits.
- HCP control unit – Air-driven, solenoid-operated hydraulic unit for medium and large machines; 1 to 4 hydraulic circuits.
- HCE control unit – Electric motor drive hydraulic unit for large machines.
- VSE non-leak valve unit – Solenoid-operated hydraulic selector valve; VSE-CS (2 circuits) and VSE-CSS (3 circuits).
- VSL non-leak valve unit – Solenoid-operated hydraulic selector valve for large-volume oil circuits.
- GSC / GSF / GSG air solenoid valve units – Solenoid valve plus pressure switch for air circuits.
- Piping materials – Pascal piping to connect the system.
Applications & Benefits
- One source for the power side: Control units, valve units and piping come from the same maker as the quick mold change equipment.
- Easier maintenance: The HCM's block valve and steel tank are designed for maintainability.
- Scaled to the machine: Units range from small and medium machines (HCS) to large machines (HCE).
- Hydraulic and air circuits: Non-leak valve units handle hydraulic circuits and air solenoid valve units handle air circuits.

How to Choose the Right Pascal Control System
- Start with your injection molding machine size and tonnage.
- Count the hydraulic circuits your quick mold change equipment needs.
- Pick a control unit: HCS for small and medium machines, HCM or HCP for medium and large machines, or HCE for large machines.
- Add non-leak valve units (VSE, or VSL for large-volume oil circuits) and air solenoid valve units (GSC, GSF or GSG) as needed.
- Include piping materials to complete the system.
Why Pascal Control Systems Are Trusted
- Complete system: Pascal supplies control units, valve units and piping, plus its own pumps, pressure switches and valves.
- Built for maintenance: Pascal designed the HCM with a block-type valve unit and a steel tank that resists impact and heat.
- Engineering support: Pascal provides 2D CAD (DXF) for HCS, HCM and HCP in 1 to 4 circuit versions and for the VSE valve unit.
