Cost Justification for Injection Molding Machine
Cost Justification for Injection Molding Machine
(OP)
I would like to make a cost justification for the purchase of one injection molding machine of 700 TON. My prospects to compare are between:
· Used machines
· Taiwan, Korean or Chinese machines
· First level machines (Engel, Milacron, Krauss, Husky)
What advantage and disadvantage, technology comparison, cost-benefit could you suggest.
Thank you for your comments, articles or links.
I appreciate your supprot.

If you are moulding engineering parts with 1" section, the machine speed and accurate control becomes irelevant, however, if you mould thin section, fast cycle, the machine speed and control becomes very critical

Pay a little more to ensure it will do the jobs, current and future, but don't pay for exotic, expensive features that you will never use.
For example, if you have a one minute cooling time, cutting half a second of the closeing time, or a second of the fill time, makes little difference in percentage terms re total cycle, however you still need to pay the bill for the extra capital investment, while the machine sits idle, waiting for the part to cool. On the other hand, if you have a high efficiency barrel with high speed mixing and high shear, to improve cycle times in a thin wall PP packaging application, you may very well degrade extrusion grade polycarbonate, being used in a transparent surfboard fin, or a thick wall acrylic lense for instance.
It really is horses for courses.
