During operation of the plastic injection molding machine,
the maximum clamping force of the injection molding machine
is required only at few mm stroke during the injection is
undergoing after the mold is closed.
The below animation is for your understanding our HWC clamping
system quickly.
To get more details, please see the next pages.
As you see above, HyMEC's Hydraulic Wedge Clamping
System (HWC) is an innovative device for the clamping
systems of the plastic injection molding machines. When you
installed HWC on your machine, you do not need any big hydraulic
cylinders.
For instance, you will need 100 tons HWC (cylinders) clampng
deivce instead of 2,000 tons hydraulic cyliner as HWC creates
15-25 times stongclamping force. By adopting HWC, you can
save the production cost, the spare parts for wear, maintenance
expense and electric power rate. of the injection molding
machine.
HWC consists of wedges with clamp cylinder, take-up
unit with hydraulic cylinder(s), working wedge, front wedge,
Jack screw with nut. The other parts, such as platen, tie-rod,
ejector etc., are more or less same to that of the conventional
injection molding machine, toggle or direct pressure type.
HWC has the follwoing features;
HWC creates the strong power by the wedge clamping
device with small hydraulic cylinder, 1/15 - 1/25 of the
clamping force of the conventional injection molding machine.
HWC requires only small cylinder and pumps so that
you do NOT need such large capacity hydraulic cylinders
and pumps. Quite smaller equipments are used with HWC. As
a result, you can produce the cost-effective injection molding
machines at lower production cost.
HWC has a simple mechanism with a rigid structure
and minimizes the friction resistance with newly developed
wedge system with roller bearings. Our testing of injection
molding machine equipped with HWC (old model), shows no
problem at all for 7-year operation. The machine still works
well with good performance and capacity.
