TIPS FROM OVER-50-YEAR EXPERIENCE

Cofit has been dealing with research, designing, and manufacturing of different kinds of screen changers, mostly intended for plastic extrusion lines, for over 50 years. When a continuous extrusion line is started, taking key decisions is essential to make the difference between a profitable project and a problematic one.

Here follow 6 important pieces of knowledge we have achieved over the years. They focus on proper designing and managing of a continuous plastic extrusion line intended for the production of high-quality film.

1. SECTORS MOST CLOSELY INVOLVED IN PLASTIC FILM PRODUCTION

In the plastic extrusion sector, film production has risen markedly in recent years. Film products are increasingly required in sectors as varied as medical and food ones, in particular whenever characterized by high quality.

The growing interest in plastic film is due to plastic film production intended for high tech applications or items characterised by a high degree of innovation.

In such fields as food, medical, construction, pace of innovation is constant and production processes need to adapt as rapidly as possible. Therefore, availability of high-quality film turns out to be essential. For further details:

2. COST EFFICIENCY IN A CONTINUOUS PLASTIC EXTRUSION LINE

There are some basic rules to follow when designing a continuous extrusion line in order to minimize costs and keep high-quality film production sustainable. For further details:

Extrusion line cost optimization At the manufacturing stage of a continuous plastic extrusion line, certain choices prove to have a significant economic importance with a view to production cost optimization. In particular, selecting the right filtration system and screen changer can move the needle on quality performance and cost effectiveness.

3. MIXING VIRGIN RAW MATERIALS AND RECYCLED PLASTIC – WHY?

A shrewd selection of polymer characteristics and production processes is essential for the production of high-purity thermoplastic film.

In particular, mixing a percentage of low contamination recycled plastic with virgin plastic as raw material is often required; similarly, it is important to equip the extrusion line with a high-performing continuous screen changer to filter impurities and achieve top quality applications. For further details:

Mixing virgin and recycled raw materials for the production of plastic film It is often necessary – and sometimes required by regulations in force – to provide for the use of mixed virgin and low-impurity recycled raw materials in plastic extrusion processes, mixing the two kinds of polymers adequately.

[4] CHOOSING SCREEN CHANGERS WITH NO MOTOR OR HYDRAULIC OR PNEUMATIC COMPONENTS

Whenever designing and manufacturing plastic extrusion systems intended for the continuous production of high-quality applications, screen changer is an essential component, which must not affect extrusion line efficiency with production interruptions due to maintenance or replacement interventions.

This is the reason why screen changers with no motor or hydraulic or pneumatic components represent the ultimate solution for continuous plastic extrusion systems intended for thermoplastic film, medical and food applications included. For further details:

Simpler screen changers for continuous production Whenever continuous plastic extrusion systems aim at producing high quality applications, screen changers with simpler mechanisms are the best choice ever. A continuous self-cleaning screen changer, with no hydraulic or pneumatic systems or motors, will soon prove to affect the relevant purchase budget less and will soon almost zero any maintenance costs, while keeping on offering unrivalled quality.

5. CHOOSING COST EFFECTIVE INDEED TOP PERFORMING SCREEN CHANGERS

Production continuity and absence of process interruptions due to maintenance, cleaning and component replacement interventions are essential when assessing the efficiency of a plastic film continuous production system. The optimal screen changer features a simple design, is self-cleaning, never stops, is cost effective, indeed offering excellent performances. For further details:

Cost-effective screen changers for high-quality plastic film When extruding plastic for the production of high-purity film, a cost-effective and maintenance-free continuous self-cleaning screen changer is essential to offer significant savings and end product high quality.
