In highly regulated sectors such as the manufacturing industry, quality is an essential technical requirement. Having internationally recognized quality certifications not only demonstrates professionalism but also ensures standardized processes, reliable traceability, and consistent products. Any certified company seeking to integrate into global supply chains must operate under ISO standards and robust quality control systems that guarantee efficiency, safety, and regulatory compliance. At Plásticos Truher, we embrace this commitment rigorously, implementing certifications that validate the excellence of our processes and enable us to meet the demands of the most critical sectors of the market.

1. What are quality certifications and why are they critical for the industry?

Quality certifications are external validations issued by accredited organizations that confirm a company operates under a documented, controlled, and audited Quality Management System (QMS).

According to Cuerva Energía, certifications “ensure that the products and services offered by companies meet previously defined standards,” acting as an endorsement for clients, auditors, and regulatory entities.

In the plastics industry—where performance, repeatability, process capability (Cp/Cpk), and traceability are essential—this becomes even more relevant.

A certified QMS guarantees:

• Controlled processes under methodologies such as FMEA, PPAP, APQP

• A preventive approach based on risk analysis

• Reduced variability and fewer defects

• Complete documentation and traceability for each production batch

• Compliance with international and sector-specific standards

2. Technical benefits of a certified company

Certification provides concrete benefits for any organization in the manufacturing sector. With a quality management system such as ISO 9001, processes become more stable, measurable, and controlled, reducing variability, errors, rework, and waste. This not only improves operational efficiency but also optimizes costs and enhances product reliability.

In highly demanding sectors like automotive, certifications such as IATF 16949 are essential because they establish advanced requirements to ensure process consistency. This includes practices like change control, prototype validation, supplier management, metrological verification, and performance reviews using technical indicators. These requirements allow certified suppliers to maintain a level of quality capable of withstanding rigorous audits and global industry standards.

Certified systems also promote a culture of continuous improvement, based on data and periodic reviews, driving more accurate decision-making and long-term efficiency. All of this is complemented by environmental policies, impact assessments, legal compliance, and operational controls that ensure safer and more sustainable processes. Altogether, certification means building a stronger, more reliable operation prepared to meet the demands of modern industry.

The main certifications are:

• ISO 9001:2015 – Quality Management System applicable to any industry

• IATF 16949:2016 – Automotive-specific standard based on ISO 9001 + additional requirements

• ISO 14001:2015 – Environmental Management System

• IQNET – International recognition validating ISO certifications globally

4. What do these certifications mean for the customer?

For customers, working with a certified company means reduced risk and guaranteed consistent results. Certifications not only confirm that products meet specifications but also validate the entire process behind each part. This translates into greater reliability, as each production batch goes through documented and standardized controls that ensure its quality.

Customers also benefit from complete traceability: every component can be tracked from raw material to final delivery, which is essential in sectors like automotive, where precise and verifiable information is a mandatory requirement.

Additionally, working with a certified company brings transparency and stability to the supply chain. Customers can access audits, evidence, and objective performance reports from the supplier, reducing uncertainty and strengthening the technical relationship.
