WD Hearn's second triple Injection Moulding Machine installation since signing with NPC

At the end of July 2026 WD Hearn completed the installation of three NPC72 Premium Plastic Injection Moulding Machines at a renowned electrical products manufacturer in Cape Town. The project marked WD Hearn's second triple Injection Moulding Machine installation since signing with NPC just two years ago, another ground-breaking moment for 2026.

About the NPC72 Servo-driven Injection Moulding Machine

The NPC72 is a 72-ton servo-driven machine engineered primarily for small-to-medium plastic components requiring highly repeatable injection control and increased mould capacity.

Core Technical Specifications & Design

• 72-Ton Clamping Force: Provides highly balanced clamping suitable for consistent parts.
• Servo Hydraulic System: Equipped with an energy-efficient servo motor and pump that reduce cycle times and optimize power consumption.
• Bi-Metallic Screw: Includes a durable, wear-resistant bi-metallic screw assembly as a standard baseline.
• Advanced Controls: Features a 10-inch LCD display running multi-language software for seamless parameter tuning.
• Back Pressure System: Built with a digital proportional back-pressure system to refine plasticizing consistency.
• Integrated Subsystems: Includes one pre-installed air blow device and one core-pull device.

Primary Applications

• Short-to-Medium Runs: Optimised for rapid toolroom development and variable production workloads.
• Electrical Components: Perfect for manufacturing precise housings, switches, and insulation components.
• Automotive & Packaging: Ideal for small automotive details and high-accuracy consumer packaging parts.
