If you are looking for a used plastic injection molding machine, it may 
be best to start by examining your current equipment. You may be able 
to find a similar machine at a lower price, if you look around. There are 
a few factors to consider when purchasing a used machine, including 
whether you need a robotic interface or specific hydraulic and air 
functions. 
Then, you can start comparing prices of different machines, which can 
help you decide which machine will suit your needs best.
The most common plastic injection system mechanism is the 
reciprocating screw. In rare cases, two-stage screws are used.

The plastic is fed into the mould through a screw, which rotates to melt 
it. The screw also acts as a ram to inject molten plastic into the mold. 
The screw is fitted with a non-return valve, which prevents back flow of 
melt along its threads. The screw itself can be made of a variety of 
materials, including ABS and PC, and can also be customized for a 
variety of applications.
The maximum clamping pressure on a plastic injection molding machine 
is 68 tons, and this figure does not include the clamping force. Clamping 
pressure is essential to the quality of the finished part, as too much or 
too little pressure will lead to poor results.

Additionally, if the clamping pressure is too high, flashing will result. In 
addition, pressure has a direct impact on the viscosity of plastic, 
affecting the viscosity. MFI is a metric that indicates how easily a plastic 
compound flows under pressure. This factor is also considered when 
purchasing a used plastic injection molding machine.
