How to read this list
All entries come from the companies’ own websites or public directories, checked on 12 October 2026. Processes, machines and certifications are as stated by each company, not verified by Fractio; request current certificates (number, body, scope) before relying on them. Listing does not imply any commercial relationship with Fractio, confirmation of interest in new customers, or suitability for your part. Companies that wish to correct or remove an entry can write to miguel@fractio.se.
“Both” means the company makes the mould and moulds the parts, which shortens iteration. Mould-weight capacity (e.g. “to 35 t”) is given where stated; injection tonnage is rarely published. Sector figures for the cluster are in Portugal’s industrial clusters.

Patterns worth knowing
- Two poles: Marinha Grande–Leiria–Alcobaça–Batalha (the historic cluster, CEFAMOL and CENTIMFE) and Oliveira de Azeméis in Aveiro district (Simoldes, Olesa, JDD, Mold World, Azemoldes).
- Automotive dominates; several groups state IATF 16949 (Iberomoldes, Iber-Oleff, Vipex, Ribermold, Celoplás, Socem units). Medical-grade moulding with ISO 13485 and cleanrooms exists at Vangest/EHTP, Celoplás, Sevlaires and TCC/Plásticos Futura.
- Several groups run plants in Mexico, Poland or Germany — useful if you need the same tool serviced in two regions.
- Where only a certifier logo is shown without naming the standard, the entry says so; ask for the certificate.
Next step
For an injection project the questions that decide price are the tool (cavities, steel, life, ownership) and the series (volume, resin, decoration). Describe your moulding requirement and Fractio briefs the candidates that fit.
Discuss your sourcing project
Fractio helps Nordic buyers search for manufacturers in Portugal and coordinates quotations, samples and follow-up from Gothenburg. Scope, responsibilities and remuneration are agreed before work starts; an enquiry is not an order.
