Moulds

The blow mould plays a fundamental role for the production of bottles. At Urola, we cover the entire process; bottle design, mould manufacturing and sample production.

This comprehensive service is included for moulds used in the extrusion blow moulding process (PE, PP, etc.) as well as for those used in stretch blow moulding (PET, etc.). It also extends to our after sales mould service, maintenance, etc.

Consulting services

Consulting services

Our service begins with a customer consultation regarding container design, taking the following factors into consideration:

  • The product to be packaged.
  • Aesthetic factors.
  • Functionality.
  • Appropriateness for the container manufacturing process.
  • Technical characteristics required of the container.
  • Conditioning factors of the filling process and other line elements.

Container and mould design

Container and mould design

We have the most appropriate means available for developing the packaging and mould:

  • Specialized technicians.
  • Powerful 3D design computer tools to optimize the container and the mould with the possibility of conducting simulations via finite element analysis.

Mould manufacturing

Mould manufacturing

We utilize CNC machining centres and other auxiliary machines to manufacture maximum quality moulds, while simultaneously offering considerably reduced deadlines.

The generation of mechanized programs based on digitalized design definition allows for a connection between design and machining systems. Similarly, digitalization based on existing model designs.

When manufacturing the moulds, there is a close control of dimensionality as well as cooling circuits.

Sample manufacturing

Sample manufacturing

When the project includes new packaging development, the samples manufactured from the pilot mould are fundamental for determining the validity of the container in all of its facets (aesthetic, functional, specifications, on-line behaviour, transport, etc.)

This service is covered by Urola when required.

After sales service and preventive maintenance

After sales service and preventive maintenance

Urola offers services extending beyond the mere manufacturing of moulds: we accompany the customer in mould maintenance throughout its service life, in order to ensure that optimal process conditions are maintained.

For this we conduct substitution operations for wear parts, repairs, review of air outlets, review of cooling circuits, etc.
