7. clamping force display and auto adjustment (no special sensor is required)
8. three main axes can change to hydraulic or electric control independently. they all support a linear or non-linear system.
◦ clamping axis supports hydraulic clamping, toggle clamping and ball screw with toggle (electric, non-linear) clamping.
◦ ejection axis supports hydraulic clamping and ball screw (electric) clamping.
◦ injection axis supports hydraulic injection, ball screw (electric) injection, and injection with crank mechanism (electric, non-linear).
9. production quality data output such as cpk and ppk are generated automatically.
monitoring and quality management are performed by spc (statistic process control) with alarm and machine halt function.
10. intelligent energy management is performed in each phase of a cycle.
no. of shots and molded parts are recorded for costing control and calculation.
11. intelligent time management is performed in each phase of a cycle.
the production costing can be minimized thanks to energy and time management.
12. free core pull function:
chen de has developed a new control system to solve mold design with complicated core pull requirements. besides basic features, there are some special features as shown below:
a. core in/out mode:
core out:
• before mold open
• during mold open
• mold open on-fly
• after mold open (before ejection)
• after mold open (after ejection)
core in:
• before mold close (before ejection)
• before mold close (after ejection)
• during mold close
• mold close on-fly
• after mold close
(each core pull can be set independently)
b. stop core in/out by:
• time
• limit switch
• counter
• position (analog / digital)
(each core pull can be set independently)
c. safety position setting of a moving platen during core pull:
a moving platen stops moving further if it is already to its set position until core in/out is done. this function is only for
• during mold open/close
• mold open/close on-fly
d. core in/out with holding:
• only specified directional valve for core pull is energized
• specified directional valve for core pull is energized as well as the holding pressure setting
e. flow and pressure settings for each core pull:
• single phase analog setting
• multi-phases analog settings (phases can be switched by time or position)
f. free core pull function:
priority setting to each core pull
g. driving source of core pull function:
• hydraulic
• electric
• servo drive
(in addition, there are core pull safety protections e.g. safety alarm, complete return signal etc.)
13. precise hot runner function
• high speed industrial ethernet communication method (based on epa standard)
• pid parameters can be set automatically and fine-tuned manually. temperature precision up to ±ºc.
• support 128 temperature control and expandable
• each hot runner channel can be on/off independently.
