Injection molding machines. (Equipment).
The PM18 bench-top injection molding machine is used in product
development, model making, prototype molding and short run production
applications. A lever actuated clamping mechanism keeps mold halves shut
with 18 tons of clamp force. It injects up to 3 cu. in. of plastic melt,
for up to 2 oz. maximum shot size, with 10,000 psi. Both functions are
variable through pressure regulation. Injection barrel and plunger are
made of hardened tool steel in close tolerances. Purge button
facilitates one shot cleaning of the barrel and the 1-1/2" eject
pin stroke can open the mold as well as eject the part. Maximum mold
size is 8" x 8" x 5" thick and air consumption is 1/3 cu.
ft. per molding cycle. Mold type needs to be a hinged book type mold or
one that allows the operator to place the top half on the bottom half by
hand. The entire mold is pneumatically shuttled out to the operator for
ease of handling. The semi-automatic cycle will then repeat when the
operator starts the cycle with the anti-tie-down "opto touch"
buttons. Components include an Allen Bradley mini PLC, solid-state
temperature controller and digital timers for controlling the mold
