Closed Mould Tooling

 Polymer → Closed Mould Tooling → Finished Subsea Component 

At D&M Pattern and Tooling, we design and manufacture closed mould tooling for the precise pouring or pumping of polymers, predominantly used within the oil & gas and subsea industries. Built with accuracy and durability in mind, our closed moulds ensure consistent results even under the most demanding production and environmental conditions.

Closed mould tooling offers excellent control over material flow, part geometry, and surface finish. By containing the polymer within a sealed system, we reduce waste, improve consistency, and create strong, reliable components that meet strict industry standards.

What Our Closed Mould Tooling Delivers

  • Precision control – Accurate shaping and repeatable results every time.
  • Durability – Built to withstand demanding subsea and offshore environments.
  • Efficiency – Reduced material waste and shorter production cycles.
  • Reliability – Consistent results for critical applications.
  • Custom design – Tailored to your specifications and process requirements.

Typical Applications

  • Subsea insulation components.
  • Offshore buoyancy modules.
  • Protective housings and casings.
  • Polymer encapsulation for electrical and mechanical assemblies.
  • High-performance parts where strength and reliability are essential.

 By combining our knowledge of polymers, specialist materials, and advanced machining, we create closed mould tooling that delivers both performance and value. Each tool is engineered with the precision required to meet the complex demands of oil & gas and subsea projects, ensuring compliance and long-term reliability.


At D&M Pattern and Tooling, we understand that failure is not an option in these industries. That’s why our closed mould tooling is designed to deliver accuracy, efficiency, and confidence in every project.
