Foundry field 

The working environment of foundry industry is extremely bad and dangerous, which requires high labor force and high work intensity. Casting operation in extreme working environment makes workers and machines suffer a heavy burden. Modern foundries are constantly seeking effective ways to improve production efficiency, flexibility and safety.

In order to succeed in the highly competitive die casting market, robot automation is increasingly becoming a decisive factor. The robot effectively eliminates all the weak links in the casting process, and makes the production efficiency, production flexibility and equipment availability reach the top level.

In the field of die casting, the robot is installed on the top of the die casting machine, which can save space, facilitate operation and shorten the beat time; if it is installed on one side of the die casting machine, it is easy to take parts and inserts, which has flexible installation, high utilization rate and short beat time.

In the harsh production environment, pouring is a dirty and arduous task - at least for the operators. The robot with IP 67 protection level is an ideal choice for this operation. The robot can strictly execute the pouring procedure with consistent action, and achieve good casting quality with optimized beat time, so as to improve the density of finished metal structure, reduce cavitation and shrinkage, and reduce the risk of operation in harsh casting environment.

Core bonding, core assembly, dip coating, installation and other processes have high requirements for operation stability and repeatability. No matter it is on the binder or core, the robot's action has achieved unparalleled accuracy, perfection and safety. Improving the quality level, shortening the cycle time and reducing the consumption of raw materials are only a small part of the benefits that professional robots can create. Injecting liquid metal into the mold is a key step in the casting process.

In gravity casting, the important process of molding and core making is feeding and pouring. Whether the operation is accurate or not is closely related to the quality of the casting. When the ideal pouring curve is established, the robot will operate strictly according to the program, so that the process can achieve high repeatability. The improvement of casting quality means the reduction of finishing work. Of course, shot peening, grinding or water jet cleaning of castings are still indispensable processes, and also another place for robots to optimize production efficiency and quality.

Investment casting is still a highly labor-intensive process, and automation has great potential in this field. High power robot combines power and precision perfectly, and helps to achieve a leap in production efficiency. With the increasing improvement of performance, robots have been gradually used in shell making and post production processes (including grinding and polishing of castings). In order to further improve the productivity and flexibility of investment casting, the foundry is exploring how to introduce robot automation in wax tree planting.

Lost Foam Casting (LFC) has created an opportunity for designers and producers which is beyond the reach of traditional technology. In this highly precise new technology field, the robot business department has launched a series of products to save manpower, improve ergonomics design and optimize process control. Robot is the best choice for coating, de coating, processing and other processes, which are properly protected by robot application software system.

Surface treatment is essential for most castings, as are cleaning and machining. Robot automation has become the conventional process of die casting workstation, hard mold casting, sand casting and core making. In the field of casting machining, efficient and flexible robot automation solutions have great application potential. We include casting cleaning after casting and pretreatment and post-processing of machine tool processing into the scope of casting cleaning.
