STM Toggle Injection Moulding Machines

STM H-Type Toggle Injection Moulding Machines for Plastic Manufacturing

The STM Toggle Injection Moulding Machines are high-performance plastic processing machines designed for efficient, accurate, and repeatable moulding operations across a wide tonnage range from 80 Tons to 800 Tons. Built with a robust H-Type toggle clamping mechanism, these machines deliver high clamping force, fast cycle times, and stable mould locking, making them ideal for both mass production and precision plastic component manufacturing.

Engineered for continuous industrial operation, STM toggle injection moulding machines are widely used by plastic moulding units, OEM manufacturers, and contract moulders producing components for automotive, packaging, electrical, and consumer product industries. The toggle mechanism ensures energy-efficient operation while maintaining excellent mould protection and dimensional accuracy.

Machine Construction & Clamping System

The rigid machine frame combined with an H-Type toggle system provides uniform clamping force and long service life, even under high-pressure moulding conditions.

Key technical specifications include:
• Machine Capacity: 80 Ton – 800 Ton
• Toggle Mechanism: H-Type Toggle
• Clamping Force: 800 kN – 8000 kN
• Tie-Bar Distance: 360 × 360 mm to 580 × 580 mm
• Clamping Stroke: 320 – 560 mm
• Minimum Mould Height: 150 – 200 mm
• Maximum Mould Height: 350 – 580 mm

Material Compatibility

STM toggle injection moulding machines are suitable for processing a wide range of thermoplastic materials such as PP, HDPE, LDPE, ABS, PS, PET, Nylon, PVC, and engineering plastics, ensuring flexibility across multiple product lines.

Performance & Manufacturing Advantages

The toggle clamping system allows faster dry cycle times, reduced power consumption, and consistent mould locking accuracy. Stable platen alignment improves product quality, reduces flash, and extends mould life, making these machines highly cost-effective for long-term production.
