The company and its needs
APTACA Spa is a company that for over 40 years has been producing disposable and reusable plastic devices for analysis laboratories, hospitals, research institutes, chemical and pharmaceutical industries.
With over 80 plastic injection moulding and blow moulding presses and 700 moulds, the company manufactures test tubes, slides, pipettes, and containers intended for blood and urine tests, cell cultures, swabs, and pathological anatomy tests for examples.
Given their delicate use, the devices produced are subject to scrupulous quality controls that ensure compliance with European and international standards, in line with the quality management system of the company that has obtained ISO 9001 and ISO 13485 certification.
When dealing with moulding, mould cleaning is essential to ensure production that meets the required quality standards and Aptaca Spa wanted to find a better method for cleaning injection moulds.
Injection moulding is a manufacturing process in which a plastic material is melted and injected at high pressure inside a closed mould, which is opened only after the solidification of the product to allow its expulsion.
The main contaminants to be removed, in this case, are release agents and lubricating oils. To allow the easy detachment of the artifacts from the walls of the moulds, special products are used that leave residues; in addition, one of the two parts that make up the mould is mobile and requires adequate lubrication which, however, can reach the figures.
It is also possible that the moulds need to be cleaned of residues left by the gases that are created in the presence of pressure and high temperatures.
Aptaca Spa would formally carry out the cleaning activities manually with rags, chemical products of various kinds and a good dose of elbow grease, but this process requires quite a long time to achieve satisfactory results.
The company wanted to achieve higher productivity and when Safetykleen proposed an automatic and ultrasonic cleaning solution, Aptaca Spa didn’t need to think twice.
