Das ist falsch. PIs sind vom Material eher mit injection molded chips vergleichbar die auf umgebauten Compression molding maschinen gefertigt werden. Es sind keine "echten" clays.

man hört die Begriffe überall, aber darunter vorstellen kann ich mir nicht so recht. Compression molding- injection molded
wiki: injection molded:
Zitat:
Injection molding (British variant spelling: moulding) is a manufacturing technique for making parts from both thermoplastic and thermosetting plastic materials in production. Molten plastic is injected at high pressure into a mold, which is the inverse of the product's shape.
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms. Compression molding is a high-volume, high-pressure method suitable for molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics can also be compression molded with unidirectional tapes, woven fabrics, randomly orientated fiber mat or chopped strand. The advantage of compression molding is its ability to mold large, fairly intricate parts. Also, it is one of the lowest cost molding methods compared with other molding like transfer molding and injection molding, moreover it gives little waste on material provides advantage on expensive compounds.

Palm Imorts kann man doch ölen mit sichtbarem Erfolg, Faux nehmen nach Eigenerfahrung nicht das Öl auf.
