PLASTIBLOW BLOW MOULDING MACHINE FOR MEDICAL ARTICLES PRODUCTION
The medical articles field, in which Plastiblow is operating with a strong presence, is one of the niche markets that suffered less the last recession, and where it’s possible to find many interesting blow moulding applications. Many polymeric materials are used for medical articles production: from HDPE and LDPE to PVC and PET, from PP and PC to thermo-polymers such as Teflon and polyeteramides. The choice of the most suitable material holds a predominant importance in this field, in particular when the application concerns the manufacture of a device that is in directly contact with the human tissue, or an apparatus that must sustain continuous sterilizations in an autoclave. In the past years, Plastiblow have designed many blow moulding machines for the production of medical articles such as test-tube and pipes for laboratory analysis, little pumps for ECG suction cups made in thermoplastic rubber, soft PVC bags and Teflon or Ultem articles for hospital use, inhalers and feeding-bottles made in Makrolon, polypropylene bottles for physiologic solutions, PVC dialysis tubes, as well as little bottle for pills, eye-wash or nasal drops made in PE, PVC or PETG. Each of these projects has produced specific problems of planning, design and setting, sometimes requiring the use of special metallic alloys suitable for very high working temperatures necessary for the processing of unusual plastic materials. The knowledge of its own capacities, based on their experience of forty years in extrusion-blow moulding field, allows Plastiblow to transform the continuous technical challenges that customers present into stimulating opportunities to growth. In the medical field the servo-driven blow moulding machines are a real success, in particular for the total absence of any hydraulic devices or components which avoids any contamination of the products or of the atmosphere and allows the use of the machine in sterile rooms and in controlled atmospheres. With the new generation blow-moulding machines Plastiblow has been able to combine the advantages of its own kinematics motion, with the technology of the electric axes driven by brushless motors. This has produced many advantages such as:
- Consistency of movements, because, without oil, there are no differences in movement when the working temperatures changes;
- More production, thanks to faster cycling and the reduction of production scrap due to more consistent movements;
- Lower running costs due to less energy consumptions;
- Lower maintenance costs due to the lack of hydraulics components;
- Reduction of environment contamination due to the absence of oil and reduced noise levels.
