injection molding machine calibration. My career in plastics has spanned
well over 20 years, all of it in injection molded medical device
manufacturing. Obviously, maintaining current calibration of equipment
is critical to insuring that any process remains in a validated state.
Virtually all injection molding machine manufacturers will state that
their equipment is capable of maintaining pressures and speeds to set
point, for example, within X% , depending on design. So, it is possible
that particular injection molding machine has drifted off target due to
some unknown reason. Perhaps actual injection pressure is not within
tolerance of the set pressure. Same goes for injection velocity, screw
speed, back pressure, etc. As I had mentioned in an earlier, just
because something is set to a particular value does not mean the
equipment is actually operating that way. Hopefully injection molding
company has in place a good P. M. program to keep all his equipment
running as designed. Anybody want to add comments from their own
experience? ? ?

- Business Description: Sometime we are facing the problem is small part but bigger tonnage, I
am not sure how the product look like, maybe the plastic part is
necessary need the high clamping force by projection are, normally we
try to avoid that and adjust on the plastic injection mold design. What can I suggestion is, you can try to use high speed plastic injection molding machine with special small Nozzle Dia. screw and try to run as fast as possible, and normally special product need to custom make or design the manifold, unless the plastic injection mold is using standard manifold, shot weight not consider when injection mold make.
If everyone would take a second and read the initial question again. Bruno would like to know what the record is for a 1000 ton change time and if it could be done in 10 min or less. There is a big difference between injection mold change and last part to first good part. It is nice to see all the sales folks jumping on the blog and trying to get a sale. I would think it a no brainer that the larger the plastic injection molding machine and the faster the change time to more costly the system and the longer time to pay for the investment in the automation.
