PROCESSES
In consideration of the complexity and peculiarity of the customers’ projects and the desired characteristics of the final product, several production processes are proposed.
FILM BLOWING
The raw material moulded in an extruder flows through the head of the unit, which forms a bubble; then it is blown, cooled, and rolled. It can be laminating film, packaging film, agricultural film, textile or clothing storage film, or other packaging materials.
BLOWN MOULDING
The mass, moulded in an extruder, is pushed into a mould; it is then pressed and blown until a blown hollow product is formed. This is a process to make bottles, various containers and household items.
ROTATIONAL MOULDING
Powdered raw material is poured into a container; products are moulded while the container is being rotated and its surface is heated up; then the products are removed from the mould. Owing to properly formed stiffeners, these products can withstand high mechanical loads.
EXTRUSION PROFILES, SHEETS AND PIPES
Sheets (rolls are used for calendering), profiles, and pipes are formed from moulded mass in an extruder. This process can be used to produce various types of pipes, window frames, and vehicle parts.
INJECTION MOULDING
The mass is injected into a mould where the product is formed. This manufacturing process is suitable for all thermoplastics and is used to make containers for cosmetics and food.
CAST FILM
During this process, film is formed on cooled rolls that determine the properties of the film, including its thickness, similarly to sheet extrusion. Plastic films can be moulded into sheets for a variety of applications, ranging from protective packaging to credit cards.
FOAM SHEETS AND FILMS
Production is carried out in several ways, but always by feeding foam material to an extruder and obtaining the final sheet or film according to the shape of the nozzle of the unit. Such products have relatively low density, require less raw material, but are durable and resistant.
THERMOFORMING
Products are formed from sheets where the heated sheet is not melted but is softened and then vacuum formed or moulded. It is mostly used in food packaging but can also be adapted to the needs of the toy, vehicle or catering industries.
RAFFIA
This is a process similar to sheeting but sheets additionally cut in its course are pulled to make threads and bands. Those are then used to weave products, such as polypropylene bags, sacks, and so on.
