What are the advantages of producing shovel teeth by EPC process?

Such castings are generally produced by traditional sand mold casting process. Because there are many sand cores, complicated process flow, time-consuming and time-consuming, and the technical and practical operation level of employees is high, it is difficult to remove the rough edges of bucket teeth produced, and the unqualified rate is high. EPC has many advantages in technology and economic development:

(1) The exchange series of Shengang does not need a core, which can save the core making process and relevant machinery and equipment.

(2) There is no analysis surface and no core gap, so there is no burr and burr on the casting.

(3) It can reduce or even cancel the mold lifting inclination without considering the main process parameters such as negative value analysis and negative value of sand core, so as to improve the specification precision of castings.

(4) Polyurethane foam mold is very easy to bond and assemble.

(5) Good natural working environment and low production cost.


Excavator bucket teeth


In order to give full play to the advantages of EPC and improve the process output rate, bucket teeth manufacturers can choose group casting to forge bucket teeth. The bottom suction negative pressure sandbox is used. 10 pieces are placed in a box. The tip of the bucket teeth of the excavator is facing down and placed in the sandbox parallel to each other. 5 pieces are placed on both sides of the transverse sprue, as shown in Figure 8-9. The closed pouring system software is selected without setting the gate.

When pouring, first point the end straight sprue, and then pour stably and quickly, so that the liquid steel can fill the rubber inlet cup from beginning to end until the pouring is completed. In this way, EPS in the sprue can be gasified quickly and filled with liquid steel in a short time, which can reasonably avoid negative pressure pumping steam into the concave mold. In addition, a certain static working pressure can be created in the pouring system software, so that the liquid steel is not easy to roll into steam and sediment in the whole filling process, and the defects such as air outlet and sediment can be reasonably prevented, In addition, it can also avoid waste caused by partial box collapse caused by casting parts.
