Internal quality-control laboratory
In-house quality control, guaranteed reliability

Quality control with our internal laboratory
Verified reliability before delivery
The laboratory is a key element in Goa Gomma’s quality management system.
Every compound undergoes physical-mechanical testing according to documented, traceable procedures, using certified instruments operated by qualified personnel.
The goal is to ensure every batch meets requirements, delivers stable performance and is fully compatible with the customer’s production processes.
Standard tests and advanced testing
All compounds are tested before delivery, with standard tests including:
Hardness (Shore A)
Density
Rheometric curve
On request or based on specifications, we also perform:
- Tear testing
- Elongation at break
- Tensile strength
- Aging in air or liquids
- Dedicated visual or functional inspections
All results are recorded and archived to support full batch traceability.
Laboratory equipment
- Reometer
- Durometer
- Densimeter
- Dynamometer
- High-temperature ovens
- TGA – DSC
- Tensiometer (Tensor Check)
- Press for plates and dumbbells
- Oil bath
- Mini mixer for sample batches
- Bench-top equipment for rapid tests
- Palimbarometer
- Compression-set equipment
Each instruments is used according to the technical specifications required for the type of compound being validated.

Quality system and non-conformity management
Goa Gomma operates under a UNI EN ISO 9001:2008–certified quality system.
All laboratory controls are integrated in the production workflow and support rapid detection and management of any non-conformity.
Non-compliant materials are isolated, recorded and processed according to a dedicated procedure, preventing defective products from reaching customers and ensuring consistent quality standards.

A laboratory that supports design
The laboratory actively cooperates with the technical department during formulation development and optimization, providing objective data for:
- Validation of new compounds
- Verification of performance parameters
- Compliance with technical standards
This guarantees not only the quality of the final product, but also the technical accuracy of the proposed solutions.
