As we know, metal casting foundry follows various methods to cast iron. But, the most preferred and the oldest way to metal casting is sand casting. The technique has been in use for thousands of years, and currently, GPCL Group has mastered the art of sand-casting metals in their foundries.

They are known as the highest quality sand casting manufacturers in India, and in this article, we will understand how they become experts in sand casting.

The GPCL Group follows a strict process for sand casting to get the best output at the end.

GPCL Group-best Sand Casting Manufacturers In India

Isn't it the first step to begin the sand casting process? GPCL Group asks for a drawing model from the customers or creates their unique designs on paper first. Then the plan is precisely copied into a physical structure using sand, which will be used to make metal structures. The GPCL group uses sand in metal casting because it is expendable and can be given any desired shape easily. All the designs GPCL creates are precise and accurate to achieve the highest and customer-satisfying quality.

The design alone can not contribute to the highest quality, but the quality of the metal is also essential. So, to use the best quality metal in sand casting, the GPCL group follows the testing and reviewing process. The GPCL's foundries have fully-equipped labs that help test the metals precisely and select the best metal for casting. With rotary degassing, indexing, and spectrograph study, the GPCL can control the quality of metal to be used for casting.

The following process involves melting the metal to be used. In this step, the metal is kept under a higher temperature higher than the melting point of the respective metal. The metal starts melting into a fluid that will be poured into the created sand mold. The melting of the metals with greater efficiency is possible due to the gas-burned tilting aluminum melting heaters. Moreover, the electric holding ladle allows merging the two boiling parts of the metal in use.

None of the melted metal is entirely pure or without any impurities and dirt. For the best finish of metal, it is essential to have impurity-free metal fluid. So, to achieve such purity, the liquid is thoroughly cleaned before pouring it into the sand mold.

The sand casting isn't an exact method of metal casting, as the structure we get has a rough surface or sometimes an unwanted shape. Hence, the metal structure requires polishing to smoothen the rugged appearance. Sometimes additional trimming and straightening are also needed to get the perfect form. Sand casting is mainly used in creating more significant designs at a large scale at the foundries.

GPCL Group is the best sand casting manufacturer in India, and their way of approach proves that. They follow every step with proper surveillance of experts to complete every step with better accuracy. Hence, they successfully deliver the best quality sand casting to the customers relying on GPCL Group.
