As a result, new products and processes are readily developed and implemented, facilitating cost-effective creation of very feature rich and complex catheters. Since the 1990s, Avalon Laboratories and Piper Plastics Corp. have aggressively pioneered polymer solution casting technology, focusing on complex medical devices.
Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...
Filter for nozzle with a plastic toy next to it. Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today.
Bulk moulding compound (BMC), bulk moulding composite, or dough moulding compound (DMC), [1] is a ready-to-mold, glass-fiber reinforced thermoset polymer material primarily used in compression moulding, as well as in injection moulding and transfer moulding. [1]
Components produced by sand casting. Furan resins serve as binders for the casting moulds. Furan resin refers to polymers produced from various furan compounds, [1] of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation.
Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of "legs"; while flow is more symmetrical than in annular dies, a number of weld lines are ...
