Horizontal injection molding machine flexseal

servo-hydraulicfor rubberfor elastomers

Product overview
ENGEL flexseal is a dedicated horizontal injection molding machine for rubber and elastomer seal production. It is optimised for very small shot weights to manufacture flat seal rings, O-rings and similar elastomer components with consistent dimensional accuracy. The machine features a compact footprint (overall length from approx. 4,250 mm for the 3,000 kN configuration), servo‑hydraulic drive and adaptable material feeding.

Features & Benefits

• Complete solution for O-rings and flat seals: screw units developed for elastomers, compact clamping side and easy access to the mould area.
• Flexible material handling: roll-fed or automatic strip feeder options to reliably feed rubber into the plastification unit.
• Space-saving design: short injection units and compact clamping side reduce overall length to maximise production area use.
• Application support: over 40 years of elastomer processing experience integrated into machine concept, application engineering and service.
• Ergonomic mould area: compact clamping unit suited to low mould heights and short opening strokes, enabling ergonomic manual operations.

Technology & Machine Components

• Control system (CC300): modern operating logic with customizable configuration; integrated control for robots and peripherals.
• Injection unit optimised for small shot weights: precise dosing and melt quality for common rubber compounds.
• Screw and plastification designed for elastomers to ensure consistent processing at low shot weights.
• Material feed configurable to raw material supply (roll feed or automatic strip feeder) for continuous, reliable processing.

Applications

• Flat seal rings
• O-rings
• Other small rubber/elastomer components
• Optionally solid silicones, depending on configuration
