Thermosetting pol ymers are particular polymers that once produced can not be remelted without going through a complete and definitive chemical degradation. The thermosetting materials are processed to arrive at a finished product in two phases: in the first phase the polymer chains are created, while in the subsequent molding phase-which is represented by a… Continue reading Molding of thermosetting polymers
The people who get on in this world are the people who get up and look for the circumstances they want and if they can’t find them, make them. (George Bernard Shaw) The Ansa Compositi Group has always been involved in the preparation and production of plastic items for the fast-moving consumer goods field, which… Continue reading Successful plastic items
Precision: – Being precise; exactness, meticulousness in doing something, in formulating one’s own thought; – In experimental sciences and technique, the more or less high degree with which, in carrying out the experience or workmanship, one approaches the pre-established conditions. (Treccani Dictionary) Every company operating on the market, regardless of whether it deals with the… Continue reading The value of precision in the molding activities (thermoplastic and thermosetting)
“The customer can come into the company even with just an idea: we think of everything that is needed to realize the finished product, including the selection of the most suitable material.” This is how Antonella Zonetti, owner of the Ansa Compositi Group, describes the activities of her companies. “Thanks to the fifty years experience,”… Continue reading Plastic materials molding from A to Z
Injection molding is one of the molding methods for processing plastic materials. It works by injecting with great pressure the material previously heated in a cold mold; in the heating phase the product reaches the right degree of fluidity necessary to be injected into the mold through a piston. This type of molding process is… Continue reading Injection molding activities
Thermoplastic and thermosetting materials can be divided according to the “behavior” they assume in relation to heat. Thermosetting materials: thanks to their processing by heat and pressure they are affected by variations that permanently change their nature. After having made the object through molding machines, if the material is heated, it carbonises and is no… Continue reading Differences between thermoplastic and thermosetting materials
The thermosetting are materials that are composed of polymers joined together by chemical bonds. The highly cross-linked product structure is directly responsible for the high mechanical and physical strength (ability to withstand high stresses, loads, temperatures) compared to the most common thermoplastic polymers or elastomeric materials. Strengths: – More resistant to high temperatures compared… Continue reading Pros and cons of thermosetting technopolymers
ABS (acrynonitrile-butadiene-styrene) Thermoplastic copolymer obtained by polymerization of acrylonitrile, styrene, butadiene. Back Pressure Pressure which is applied to the rear end of the screw and causes a slowing of its translation backwards while the molten material accumulates in the injection chamber due to the rotation of the screw itself. Cylinder Part of the injection group,… Continue reading Plastic materials vocabulary
Just four years after the opening of the production site in Bulgaria, the Ansa Compositi Group sums up the first big results, proud of its work and sure of a future full of great opportunities. During the first years of the crisis that has hit all the advanced economies of the world, the Ansa… Continue reading Ansa Borima: a successful story
With the advent and subsequent improvement in the use of thermosetting composites (high performance plastic materials), in most cases, results were definitely beneficial compared to the most commonly metal materials used so far, both in economic terms and performance. The companies that have embarked on the path of renewal, also thanks to the collaboration with… Continue reading Replacing metal has become convenient: the competitive advantages of thermosetting
