In all sectors where the use of metal washing systems is required, the repeatability of cleaning results is a key aspect.

In particular, in the medical sector this requirement is fundamental since there is the need to eliminate residual contaminants from all those geometrically challenging parts in accordance with a series of very restrictive technical regulations and standards.

The impeccable cleanliness is the prerequisit for the true goal of the washing: a complete protection of the patients’ health.

The LEGHE LEGGERE LAVORATE case represents another important success for FIRBIMATIC.

Who is LEGHE LEGGERE LAVORATE and what does the company do?

Before analyzing the technical specifications and advantages of the cleaning machine let’s see together what this company deals with.

Leghe Leggere Lavorate was founded in 1951 in Buccinasco as a mechanical engineering company specialized in the production of components for the automotive sector: valves and heat exchangers.

When meeting the demands of the automotive industry in the nineties was becoming increasingly complex, the company decided to revise its strategic plan by identifying a potential niche in the medical sector susceptible to important future expansion.

Today the medical sector represents 85% of the overall production of Leghe Leggere Lavorate.

What are the cleaning needs of the medical devices?

Medical products manufactured by Leghe Leggere Lavorate are plates, screws and prosthesis components made mainly of titanium. Titanium is considered the most biocampatible metal – not harmful or toxic to living tissue.

In terms of cleaning it is important to achieve flawless results and not compromise patient safety.

While prostheses made of titanium are intended to remain permanently in a patient’s body, those made of steel are to be removed.

By installing the new Firbimatic degreasing machine Leghe Leggere Lavorate , expected to substantially improve the quality of their final product thus removing successfully oils and ferrite residues from the surface of its medical components and leaving them totally contamination free.

High quality levels are essential for Leghe Leggere Lavorate to allow its customers to obtain the necessary authorizations from their respective Ministries of Health and to propose the product on the reference market.

Features and advantages of the new degreasing machine for special components

The new degreasing machine, Firbimatic Multisolvent 200 model, built for Leghe Leggere Lavorate has actually replaced the one in use and, in addition to the cleaning objectives , it has allowed our customer to reduce their environmental impact from manufacturing and use less polluting chemicals well accepted by the medical sector .

The washing cycle uses vacuum technology and works with modified alcohol, which represents the best solution for the medical end customer .

The Multisolvent 200 machine is equipped with a single hermetic washing chamber measuring 900x300x200 mm with manual loading but already with predisposition for automatic loading and unloading.

The metal components for the medical industry are placed in special baskets of different sizes and the washing cycles are selected based on the type of washed parts.

This means that the duration of each cycle and the washing sequences may vary but, in principle, they remain between 7 and 13 minutes.

The degreasing machine manufactured by FIRBIMATIC is also equipped with a distiller that allows the separation of both vegetable and mineral oils.

The protection of the health and safety of operators

The protection of the operator who monitors and uses the system becomes even more important when alcohol and solvent cleaning machines are used.

To minimize exposure to chemicals, we have prepared a series of devices that facilitate management and maintenance operations, especially when it is necessary to eliminate the residues of vegetable oils that end up on the bottom.

The results achieved in terms of consumption and environmental impact

The technology associated with the vacuum washing cycle in the Multisolvent 200 model has greatly helped to reduce consumption and environmental impact compared to the previous system.

As highlighted at the beginning of this article, one of the most important goals achieved was that of the repeatability of the cleaning results that have become optimal and constant over time both on finished components and on those intended for other processes.

The new degreasing machine has also allowed Leghe Leggere Lavorate to obtain the ISO certification and the important awards associated with it.
