What is Quick Mold Change?
A quick mold change means that the material for the next part is in
place, automation is set-up and the mold is located and clamped in
position. With the Quick-Mold change system, the mold is clamped in
the same place, the same way, every time. Because of this, mold
changes are accomplished in the shortest time possible.
When Quick Mold Change (QMC) is implemented, companies will enjoy
the benefits of:
Reduced Inventories, due to smaller quantities runs and more
Increased Machine Capacity, by improving production and its product
Improved Lead Times, due to quick changeovers.
More Competitive, through just-in-time deliveries and better
service to customers.
Improved Quality of parts, due to repeatable positioning and
Reduced Labor Costs, mold changes can often be done by the operator
in a fraction of the previous time.
Improved Safety, the molds are under control and roll smoothly in
and out of the injection mold machine during the mold change, and
with automated systems, if the mold is not clamped properly, the
injection molding machine simply will not operate.
Why Quick Mold Change?
To survive in today’s competitive, worldwide market, manufacturers
are reducing inventory costs by running smaller batch sizes and
making shorter production runs. One way to maximize press uptime in
an environment like this is to implement faster, more effective
mold changes. That’s where QHMAG, a leading Quick mold change
system manufacturer comes in.
Honeycomb Magnetic Plate vs Standard Magnetic Plate
|Comparism||Honeycomb Magnetic Plate||Standard Magnetic Plate|
|Rigidity & Stability||Honeycomb type with double side magnetic suction structure, the
magnet of back is stronger, so the mold, magnetic plates, and the
backplane of injection molding machine are combined together, which
improve the rigidity of the plate, and avoid mutual vibration and
offset.||Only fix the fastening screws around the plate, can not be fix
screws in the middle of plate, so it can not fully guarantee the
template avoid deformation when open mold.|
|Capacity & Versatility||Thickness 37mm, increased the opening stroke, the maximum reduction
of the ejector rod and the amount of injection muzzle expansion,
better control of plastic temperature||Thickness 45mm, the capacity is small, so the mold range is
corresponding less than honeycomb magnetic plate.|
|Service life||Created in a monolithic construction: CNC machined and is
completely made in a metal, with no resins, gaskets, screws, brass
or other materials. It is extremely reliable: There are no
components subject to wear, deformation or thermal expansion.||Surface is sealed by resin potting, with aging risk.|
|Quality& Efficiency||Double-sided with magnetic force, the back suction function in the
stripping process to maintain the mold stability, to avoid mutual
vibration and offset.||Single-sided magnetism, the magnetic force in same unit area
|Clamping force||The honeycomb structure is optimized the inside of magnetic plate,
which ensure the rigidity and strength of the magnetic plate
itself, as well as the magnetic force can be concentrated in a
reasonable layout, so, no matter what size about the mold, the
template is with more powerful clamping force||The ordinary structure clamping force is dispersed and not uniform|
|Personnel operation||With LCD remote controller, in use of intelligent password
authorization, eliminating the need for key management
inconvenience, real-time quantitative feedback status of mold and
the all sensors, it is more intuitive||Mechanical control box, button control, can not quantify the
real-time reaction of mold status|

Advantages of Magnetic Clamping System
1. Easy Installation
It does not require any changes to the molds,no need to change the
appearance and structures, no need punch, just fix the magnetic
plate by bolts in the rear panel threaded hole or T-slot of the injection molding machine.
2. High Safety
The Magnetic quick mold change is controlled by Electro-permanent
magnet system which is an electrical pulse activates the system in a second (Magnetization):
the mold is held by the natural force of the permanent magnets. The clamping force remains constant
even in the absence of a power supply, it is still keep strong and continuously magnetic
force when power off and does not disappear or loss by time and temperature factors.
3. High Efficiency
Use Magnetic quick mold clamping system can greatly improve the
mold change efficiency, drastically reduces mold changeover times
(up to 90%) compared to a conventional procedure. QMCS guarantees a uniform mold clamping, that is held
using the whole contact surface. Clamping the mold with uniformity allows obtaining good
quality parts even with the first molds. The two mold halves are perfectly aligned: friction is
minimized, preserving wear of molds and the machine. Generally the mold change and mold clamping only
need 3 minutes, large mold change only needs 10 minutes.
4. Save Space
The thickness of Magnetic plate is about 37-50mm, space is small.
The magnetic quick mold clamping system does not use platens and other pneumatic and
hydraulic components,save more space and make all the peripherals of the mold in the
injection molding machine are easy for maintenance and operation.
5. Easy Operation
Magnetic quick mold clamping system clamps molds of any shape and
size with strength. A single operator easily and safely performs the operation, without working
inside the machine.
6) Economical and Practical
Use Magnetic quick change mold system means eliminating the cost of
maintenance and management of brackets, consumables, fasteners.Electricity is only
used to fix and release clamping, once the mold is safely held to the correct position,
will no longer need to use the electricity. Magnetic chuck application temperature can maximum up
to 150°C, machine weight up from 60 tons to 5000 tons.
