From concept development to full-scale commercial production, Carrick Packaging provides end-to-end project management for custom injection moulded packaging components, including flip-top closures, screw caps, bottles, and technical plastic parts.

As a UK-based injection moulding manufacturer, Carrick Packaging works closely with customers to develop high-performance packaging solutions that meet functional, regulatory, and commercial requirements.

 

Our expertise includes:

  • Custom moulded closures and caps
  • Technical injection moulding
  • Chemical-resistant packaging components
  • Design for Manufacturability (DFM)
  • Prototype development and testing
  • High-volume production tooling
  • Quality-controlled commercial manufacture

We support projects from initial concept through CAD design, prototyping, tooling, validation, and production scaling.

 

Flip-Top Cap

  • Initial Concept
  • High-Precision Mould
  • Quality Assured
  • Custom Orders

  • Initial Concept

    Product Requirement: Robust 28mm Flip-Top Screw Cap

    • Secure snap closure
    • Controlled directional pouring
    • Leak-proof performance during transport and storage
    • Chemical resistance
    • High durability under repeated use
    • Multi-million unit annual production capacity

    Industry: Chemical Packaging

    CAD models were iterated with a focus on functionality and robustness.

    Considerations:

    • Wall thickness optimisation
    • Hinge design
    • Thread accuracy and sealing performance
    • Material selection for chemical compatibility
    • Design for Manufacturability (DFM)
    • Dimensional consistency for automated production environments

     

    Prototype samples produced allowed chemical exposure trials, leak testing and hinge lifecycle tests prior to full scale commercial production. Our technical change management process ensured consistent quality and dimensional accuracy.

    Initial Concept

  • High-Precision Mould

    A high-precision 16-cavity hardened steel injection mould tool was developed in collaboration with specialist mould toolmakers.

    The tooling programme focused on:

    • Precision engineering
    • Long tool life
    • High-volume manufacturing efficiency
    • Process consistency
    • Reduced cycle times
    • Reliable dimensional accuracy
    High-Precision Mould

  • Quality Assured

    Following validation, the project transitioned into full commercial manufacture using controlled production processes supported by:

    • Robust quality management systems
    • Preventative maintenance programmes
    • Process monitoring and validation
    • Consistent batch traceability
    • High-volume manufacturing capability

    This approach ensures reliable supply, repeatable quality, and long-term production stability for industrial packaging applications.

    Quality Assured

  • Custom Orders
