A Plastic Injection Moulding Partner You Can Trust

At Hard Ferr, we design and manufacture high-performance plastic injection moulds and also produce complete, ready plastic components in-house using our own moulding machines. From rapid prototype tooling to multi-cavity production moulds, we support our clients from the earliest tooling requirements all the way through to finished, production-ready parts.

All tooling is manufactured at our Hungary facility using advanced CNC machining, EDM, and precision grinding equipment. We can produce moulds up to 5 tonnes and with overall dimensions up to 1,000 by 600 millimetres, giving us the capability to support both small and large, complex systems. Every tool is sampled, tested, and validated before delivery, with UK-based support ensuring clear communication throughout the entire process.

We produce a wide range of tooling including single and multi-cavity moulds, family tools, insert and overmould designs, and multi-component (2K and 3K) systems in both hot and cold runner configurations. Each mould is built from high-quality tool steels or specialist alloys to deliver long-term durability, stable cycle times, and consistent, repeatable performance.

What Components We Machine

We manufacture both the moulds and the final plastic components. Using our in-house injection moulding machines, we produce complete, ready parts that meet the exact specification, geometry, and performance requirements of each project.

Our production supports a wide range of applications including medical and laboratory products, automotive interior and exterior components, consumer goods, baby products, threaded plastic parts, packaging products, appliance components, overmoulded parts, and multi-component (2K/3K) assemblies. Whether for large production volumes or specialised low-volume items, every mould and every part is built for accuracy, durability, and reliable long-term performance.

Our Process

  • 01

    Requirements & Specifications

    We begin by reviewing the client’s requirements and specifications, whether in 2D drawings or 3D models. These details form the foundation for precise mould manufacturing.

  • 02

    Material Selection & Preparation

    We source the specified tool steel, alloy, or aluminium. Raw stock is cut into blanks and prepared with initial operations for machining.

  • 03

    Machining & Tool Production

    Using advanced CNC machining centres, eroding, and grinding, combined with CAD-CAM programming, we manufacture mould cavities, cores, and inserts to exact tolerances.

  • 04

    Heat Treatment & Finishing (as required)

    Tool components may undergo heat treatment to improve strength and wear resistance, followed by polishing and surface finishing for mould-ready quality.

  • 05

    Inspection

    Each mould is carefully inspected against the original specifications to verify accuracy, durability, and performance.

  • 06

    Delivery

    Once approved, moulds are cleaned, securely packaged, and delivered across the UK and Europe with full documentation.

  • 07

    Optional In-House Plastic Production

    For clients who require complete plastic components, we use the finished moulds on our own injection moulding machines to produce ready parts to specification, ensuring full quality control from tooling to final product.
