Q: I know how to use an injector, is the 99M Blow Molder

different?

A: Blow molding is accomplished via the manual extru-

sion of a molten tube of LDPE (low density polyethylene)

called a parazon. This tube is guided (by use of a pointed

pliers) over the inflation needle, and the two mold halves

are closed around the parazon. 5 psi. air is introduced into

the parazon through the inflation needle and the parazon

Injection molding operates using much higher pressures.

Pellets are heated in the heating chamber, then the chamber

is pressurized by the introduction of a ram and molten

plastic is forced through a 1/8" nozzle into an aluminum

mold. The mold is held closed by the mold clamp. Injec-

tion machines are often referred to by their available

clamping pressure. E.g.: a 10 ton machine. Clamps that

fail may introduce leakage or "flash" on the molded part.

Usually injected parts require little trimming, only the

Q: So, I only need a compressor for air powered

machines?

A: Yes. Manual machines use a mechanical advantage bar
