Why are certifications central to plastic injection molding manufacturers?

As a leading precision plastic injection molding business, Rosti knows that quality is non-negotiable — for us and for our customers.

Our commitment goes far beyond delivering high-performance plastic components. It’s about delivering them with accountability, transparency, and industry-verified compliance.

A Global Framework for Quality in the Plastic Molding Industry

Across our global production network, Rosti operates to the most stringent national, regional, and international standards — ensuring that wherever our customers are based, they can expect the same world-class quality and consistency. All of our plastic injection molding facilities have  ISO 9001 quality management certifications, alongside 3 sites that are fully FDA /IMS compliant.

These standards underpin everything from smooth production transfers between sites to scaling new programmes in new markets. Our clients know they are working with a partner who maintains robust, certified processes at every touchpoint.

Investment Beyond Compliance

Achieving and maintaining these accreditations requires ongoing investment. At Rosti, we dedicate significant resources to training, auditing, and upgrading systems to ensure we don’t just meet certification standards — we aim to exceed them. This proactive approach reflects our strategic mindset around continuous improvement, risk mitigation, and future-readiness.

Our investment also extends to pursuing new certifications that align with customer requirements, regional regulations, or new market sectors. This adaptability enables us to remain responsive and relevant in a fast-moving global landscape.

At Rosti, we hold:

• 8 ISO 14001 environmental management certifications and 4 ISO 50001 energy management certifications to continually improve efficiency and sustainability.
• 8 ISO 45001 health and safety management certifications to protect our teams and ensure safe working environments.
• EcoVadis (7), SEDEX (7), and SMETA (4) credentials, reflecting our ESG leadership and ethical sourcing standards.

Certification in contract manufacturing validates safety from design to delivery

For clients in highly regulated sectors such as medical technology and food packaging, certification is a critical reassurance. It validates that every product we manufacture follows documented, traceable processes — underpinned by robust quality controls and supported by advanced automation and digital systems. From initial design to delivery, quality and safety are embedded at every stage.

From highly regulated markets to specialist production, we ensure industry compliance is embedded in our operations:

• Medical – 6 ISO 13485 certifications guarantee the quality and traceability essential in medical device manufacturing.
• Food – 4 BRCGS certifications, 3 FDA/IMS, 1 Halal, and 1 FSSC 22001 accreditation safeguard food safety and hygiene at every stage.
• Automotive – 2 IATF 16949 certifications confirm our capability to meet the exacting standards of OEMs and Tier suppliers.
• Electronics – RBA certification ensures responsible business practices in the electronics supply chain.

Our technology investments in real-time monitoring and lights-out automation complement our certified processes, helping reduce human error, increase efficiency, and ensure reliable, repeatable outcomes.

Sustainability and Responsibility in plastics manufacturing as a standard

Our certifications also reflect our broader commitment to sustainable and responsible manufacturing. Standards such as ISO 14001 support our environmental objectives by guiding us in energy efficiency, waste reduction, and resource management. Other accreditations recognise our focus on ethical sourcing, fair labour practices, and safe working environments.

These efforts are not about box-ticking. They are about making a measurable difference — for our customers, our people, and the planet. Certifications are a framework for driving impact and ensuring that every part we mould is manufactured with integrity.

A Trusted Partner for the Long Term

In total, our global footprint includes more than 70 individual certifications and accreditations across general business management, sustainability, and industry-specific standards. 

These are not just plaques on a wall — they are proof of our investment, our capability, and our promise to deliver excellence responsibly, wherever we operate.
