Overview
The Pascal Square Core Mag Clamp (MGA) holds the mold to the injection molding machine platen with strong permanent magnets, with no bolts and no hydraulic or air clamps. It clamps at the push of a button in 0.5 to 4.5 seconds, uses energy only while switching on or off, and generates no heat while clamped. With plate options of 35 mm or 50 mm and operating temperatures of 150°C or 180°C, it is well suited to vertical and multi-color injection molding machines.
Key Features
- Instant clamping
- Clamps the mold at the push of a button in 0.5 to 4.5 seconds.
- Higher temperature rating
- Rated for 150°C or 180°C operation, depending on the version.
- No power draw while clamped
- The electromagnetic coil is energized for only 0.5 seconds to switch on or off. No power is consumed and no heat is generated during clamping.
- Strong permanent magnets
- Neodymium and alnico magnets hold the mold. Reversing the alnico magnet's polarity clamps or releases it.
- Mold misalignment detection
- An electromagnetic coil built into the magnet core near the center of the clamp plate detects if the mold moves.
- No need to standardize mold sizes
- Molds of different height, width and thickness can run on the same machine; for horizontal loading, only a spacer is needed.
- Full use of the platen
- No clamp mounting space is needed, which maximizes the mold's usable area and avoids interference from core cylinders, connectors, couplers and hoses.
Product Line / Models
The Square Core MGA can be combined with other Pascal quick mold change equipment. Examples from Pascal installations:
- Mag Clamp – 3,500 kN injection molding machine; clamps instantly without unifying mold sizes.
- Mag Clamp and Die Leveler – 1,000 kN machine; levels the mold easily and instantly.
- Mag Clamp and Die Setter – 3,500 kN machine; centering and leveling are automated.
- Mag Clamp and Die Changer (Manual) – 1,800 kN machine with a 0.6-ton mold; horizontal loading with no crane needed.
- Mag Clamp and Die Changer (Motor Drive) – 30,000 kN machine with a 30-ton mold; motor drive shortens installation time further.
- Mag Clamp, Die Changer (Motor Drive) and Auto Coupler – 2,250 kN machine with a 1.5-ton mold; coupling and mold change are fully automatic.
- Mag Clamp for vertical machines – 750 kN vertical rotary machine; no tightening bolts in cramped machine spaces.
- Mag Clamp for two-color machines – 2,500 kN two-color machine; mold installation time shortened to 45 minutes, with misalignment detection.
- Coupler Built-in Mag Clamp and Die Setter – 6,000 kN two-color machine; installs the mold and couples lines at the same time.
Applications & Benefits
- Vertical machines: Removes bolting in the cramped spaces of vertical and rotary machines.
- Two-color and multi-shot molding: On a 2,500 kN-class two-color machine, Pascal reports mold installation time shortened to 45 minutes.
- Crane-free mold changes: Pairs with Pascal die changers for horizontal loading.
- Large machines: Pascal shows mag clamps on machines as large as 30,000 kN, including a 13,000 kN machine.
- Automation-ready: Combines with die setters, die levelers and auto couplers for a fully automatic mold change.

How to Choose the Right Pascal Mag Clamp
- Start with your machine type (horizontal, vertical or two-color), tonnage and platen dimensions.
- Check your mold temperature: the Square Core MGA is rated to 150°C or 180°C; the Circle Core is rated to 120°C.
- Confirm the plate thickness your machine can accommodate (35 mm or 50 mm).
- Decide how molds are loaded and whether you want a die changer for crane-free horizontal loading.
- Plan companion equipment for a fully automatic change: auto coupler, die setter or die leveler.
