A Valencia provider produces PP food containers for Coca-Cola—microwave-safe and recyclable, meeting EU packaging regulations (EU 10/2011). A Seville shop makes ABS hair dryer housings for Philips using 20% recycled ABS to reduce environmental impact.
How to Choose the Right Injection Molding Provider in Spain?
Verify Industry Certifications
For regulated industries, certifications are essential:
- Automotive: IATF 16949 (mandatory for supplying SEAT, Renault, or Ford)
- Medical: ISO 13485 and FDA registration for US-bound parts
