[WWI] Injection moulded vs. resin vs. whatever

There are different qualities and types of plastic models.

1. Injection molding - there's a mold and plastic is injected into it under 
pressure.  But quality varies considerably, from excellent (Eduard, Tamiya), 
good (Roden), to not quite as good (A-Model, Pegasus).  Models that are 
produced in higher quantities can support more expensive (higher quality) 
molds.  Smaller quantity production requires a compromise because they won't 
cover the overhead of a high cost mold - these are called short run 
injection molded kits.

2. Vacuform - you get a sheet of plastic with the kit's pieces embedded and 
you cut them out. They are produced by sucking (vacuuming) air out of the 
vacuform machine in which a mold is placed.  Generally, these are lower 
quality kits requiring a lot more time but they can make extremely nice 
models.  The kits vary in quality from excellent (Roseplane) to less than 

Resin kits are made of "resin", which is not plastic.  You need super glue 
or epoxy to stick the parts together.
