Quality Built into the

Process,, Not the Inspection

Operational discipline, technical control, and standardization to ensure consistency in every production batch.

INTRODUCTION

Quality as a Direct Result of How We Operate

At Andes, quality is not treated as a final inspection step, but as the direct result of a well-defined and rigorously controlled production process.

Every operational variable is monitored to ensure that the final product consistently meets our customers’ technical requirements.

Quality production is not about correcting deviations — it is about preventing them from happening.

Process Discipline

Standardized Execution, Without Improvisation

The foundation of quality at Andes lies in process discipline.

Each stage of production follows defined, validated, and controlled parameters, ensuring repeatability and long-term stability.

Operational deviations are not treated as informal adjustments, but as technical events that require analysis, validation, and structured corrective action.

Applied Principles:

Defined Processes Must Be Followed
Adjustments Only with Technical Validation
No Improvisation in Our Operations
Consistent Execution as the Standard

PROCESS VARIABLE CONTROL

Real-Time Technical Monitoring

The quality of PET preforms depends directly on precise control of process variables.

At Andes, critical parameters are continuously monitored to ensure production stability.

This level of control helps reduce variations while maintaining the dimensional and functional consistency of the product.

TRACEABILITY

Full Control Over Every Production Batch

Traceability is an essential element in ensuring transparency and operational reliability.

Each production batch can be tracked according to process conditions, raw materials used, and operational parameters.

This Enables:

Certification and Quality Standards

Andes operations follow rigorous quality management standards aligned with international industrial best practices.

ISO 9001 Certification

ISO 9001 certification reinforces our commitment to:

Continuous Improvement Driven by Customer Performance

CONTINUOUS IMPROVEMENT AND CUSTOMER COMMITMENT

At Andes, continuous improvement is an integral part of our operations. Rejects, waste, and process instabilities are treated as opportunities for improvement, leading to adjustments that enhance efficiency, control, and production consistency over time. Each preform is manufactured to ensure stability throughout the blow molding process, consistency between batches, and predictable final results, contributing to greater reliability and production continuity.

Our operations undergo continuous review, with strategic adjustments designed to raise efficiency and quality standards. These improvements are supported by in-depth analysis, structured corrective actions, and the integration of proven improvements into our standard processes.
