A plastic based on amino resins.  4, fiche 1, Anglais, - aminoplastic

Record number: 1, Textual support number: 1 CONT

Amino plastics(melamine and urea) are thermosetting polymers. They are produced by a polymerization method involving the controlled reaction of formaldehyde and any of various amino-containing compounds. Offered in a variety of physical forms, these resins are widely used in molding, adhesive bonding, and coating applications.  2, fiche 1, Anglais, - aminoplastic

What makes automatic molding automatic is the mold. There are a number of requirements for automatic molding. The machine must be capable of consistent, repetitive action. The mold must clear itself automatically. This means that all the parts have to be ejected using a runnerless mold, or that the runner and the parts have to be ejected in a conventional mold. There may be some method for assisting in the removal of the pieces, usually in the form of a wiper mechanism, air blast, or robot. All machines used automatically must have a low-pressure closing system to prevent the machine from closing under full pressure if there is any obstruction between the dies. The machine shuts itself off and/or an alarm is sounded. Automatic molding does not necessarily eliminate the operator. Many times, an operator is present to pack the parts and perform secondary operations. Automatic molding gives a better quality piece and more rapid cycle. In automatic molding an experienced person usually attends several machines. Unless the powder feed and part removal are automated, this person takes care of those operations.  1, fiche 5, Anglais, - automatic%20molding

Other blow molding operations.... Fluorination surface treatment is a process to improve the gas barrier of polyethylene to nonpolar solvents. A barrier is created by the chemical reaction of the fluorine and the polyethylene, which form a thin(20-40 nm) fluorocarbon layer on the bottle surface. Two systems are available for creating the layer. The "in-process" system uses fluorine as a part of the parison expand gas in the blowing operation. The "post-treatment" system requires bottles to be placed in an enclosed chamber filled with fluorine gas. The method forms a barrier layer on both the inside and outside surfaces. This surface treatment allows low-cost, blow-molded polyethylene bottles to be used for paint, paint thinner, lighter fluid, polishes, cleaning solvents, cosmetics, and toiletries. The approach can replace other higher cost resins or coextrusion processes.  1, fiche 6, Anglais, - fluorination%20surface%20treatment

Intermittent extrusion is the second basic extrusion blow-molding category. In this process the parison is quickly extruded after the bottle is removed from the mold. The mold clamping mechanism does not need to transfer to a blowing station. Blow molding, cooling, and part removal all take place under the extrusion head, which also allows the clamping system to be more simple and rugged. The stop/start aspect of the extrusion method makes this process more suitable for polyolefin and other materials that are not heat-sensitive.  2, fiche 7, Anglais, - intermittent%20extrusion

Today, blow molding encompasses two fundamental process approaches based on the method used to create the preform or parison.
