Why is LK FORZA-III Two-Platen Injection Molding Machine FA3000/33700 an Ideal Machine for Bumper Production?

The FORZA-III FA3000/33700 is a two-platen energy-saving servo injection moldign machine with clamping force of 30,000kN produced by LK machinery for the productionn of large size plastic parts. In car bumper production it has the advantages of:

• Space between tie-bars 2000 x 1800mm for larger size injection mould --
• Non-contact tie bars with the moving platent to provide excellent mold protection --
• Improved, light-weight materials and automated systems are reducing costs and streamlining process --
• Customization features to utilize precision technology to create quality pieces to exact specifications --

And the 3200mm mold opening stroke of the injection molding machine provide more space for the robotic arms to finish the complex picking process of a car bumper.

Why to have a A/C Servo Robotic Arm to do the Car Bumper Picking?

The car bumper is a large size arc shape plastic parts with complex structure, which make the picking EOAT of the car bumper a complex system. Below a standard design of the car bumper EOAT design to show the complexity of the system.

The EOAT above shows that the picking of a car bumper is a co-working of a couple of suction cups and clippers. As the length of the EOAT for bumper picking would be more than 1meters, it'll request that EOAT is able the change the angle while have the car bumper moved out of the mold area. In this case a robotic arm with A/C servo posture will solve the problem of pkicking angle adjusting perfectly.

The SWITEK SW7730DS is a heavy duty 3 axis servo robotic arm with payload up to 75kg designed for injection molding machine from 1000~4000T. Equipped with A/C servo posture, it would be a perfect picking robotic arm for LK FORZA-III FA3000/33700 in production of car bumpers.

How is a Car Bumper Picked by a Robotic Arm with Servo Axis C from the Injection Molding Machine?

The picking robotic arms of the car bumper is SWITEK SW7730DS with servo C, which is an economic solution of a smaller car bumper injection molding. The optional servo axis A is for the car bumper injection molding system with limited space between the tie bars would be a perfect solutions of the car bumper picking.

For manay small and medium sized producer of IML containers it many not be easy to make a decision if to accept the order or not because of the small quantity at the beginning but a huge potential in the future. As the IML robot is a custom made system according to the mold design and the injection molding machine for this mold. But is there any possibility to have one IML robot for a couple of molds? The answer is yes.

The SW8 series of side entry IML robot is one of which an ideal choice for the small and medium sized producer of IML containers. With exchangeable magazine and stacking unit, the IML robot enable the IML containers producers to produce the small and medium sized IML containers and IML lids by the injection molding machine and the IML robot with simply to have the magazine and EOAT replaced for the new mold. But with this IML robot, how will the IML containers produce to achieve the maximized productivity?

To maximized the productivity of the IML system, the key would be to have the injection molding machines and the IML robots well organized according to the products. To make the change the magazine and EOATs faster, we can have the containers with wraping labeling produced in one IML system and have the 3/5 face labeling containers and the lids produced by another IML system. It's not recommended to have the containers with wraping labeling to be produced by the same IML system with an IML lids, which will need to change both the Magazine and the stacking unit and the time to start the system up would be much longer.
