Casting Suppliers – Global Sourcing Considerations

Do you know which operation performed by casting suppliers perform best suit your requirements? There are several supplier networks available when you look for any kind of casting process in metalworking. But, to find unique suppliers who conduct specific sub-process of a casting process, it requires a little conscious research about your own requirement.

For your company to know which exact casting process suits your product, you must be aware of all the corresponding processes and must be able to choose the right
match. Firstly, let us get into knowing what a casting process is!

How is metal casting performed?

The casting process involves the transition of a metal’s chemical properties through heating at suitable temperatures. The metal dissolves and melts through the continuous application of heat. The liquid metal solidifies when poured it into a mold and allowing it to cool down. This gives the desired shape to the metal according to the customer’s requirement. The output is known as Casting.

The classification of a casting process is based on the type of molds used. The first factor to consider is to find if your product or service requires an expendable mold or a permanent one. But it is important to know what ‘expendable’ is. Depending on the need, Manufacturers can either use just a one-time usable mold or a permanent mold.

In Expendable mold casting, one uses disposable molds. Whereas, in Non-expendable casting, casting suppliers use molds made of strong and non-disposable materials.

I.EXPENDABLE MOLD CASTING:

Factors for considering expendable mold casting:

  • Low-cost
  • One-time usage
  • Small-size operations
  • Require less maintenance

Types of Expendable Mold Casting:

1. Sand casting:

The process uses sand molds. These sand molds are sand particles bonded together using clay or oil or any other kind of binder that aligns with the chemical properties of the work metal.

2. Shell mold Casting:

This molding process is like the sand casting process. The size of the mold is finer than the sand particle size used in the sand-casting process. The mold material comprises resins that make the surface finish compact and clean. Also, casting suppliers heat and harden the mold shell formed during its creation. Due to the harder surface of the product mold, the precision and finish of the metal casting are much better than sand casting.

3. Plaster mold casting:

This casting process follows the same procedures as the sand-casting process, with only a difference of using Plaster of Paris instead of sand during mold formation. But this method uses only limited types of metals. Because the plaster used in this process can withstand only metals with low melting points.

4. Investment casting:

his oldest method of casting uses inflexible materials like beeswax to form the molds. On completion of the casting, these molds exhibit intricate precision ensuring no re-work requirement. Yet the material requires attention and care due to the fragility of wax surfaces.

During investment casting, a pattern forms due to wax usage. A pattern is a replica or pre-designed models of the desired metal product shapes. The casting suppliers repeatedly dip the was in a molten pool of ceramic. The wax melts by heating the ceramic mold making empty space for the molten metal to fill the molding cavity. Now, they pour the molten metal into the cavity and solidified. Finally, they remove the ceramic mold by application of vibration.

5. Evaporative-pattern casting:

During this metal casting process, casting suppliers use patterns for producing specific metal shapes. Materials that can evaporate form these patterns. There are two main processes conducted during the Evaporative-pattern casting:

Lost-Foam casting:

In this process, pattern material is foam. This process is like investment casting while the only difference is that the pattern used is foam instead of wax.

Full-mold casting:

In this process, the casting suppliers make patterns using polystyrene foam. They place the pattern inside a mold and fill the surrounding surface using materials like sand. Finally, they pour the molten material inside the mold. This molten metal occupies the space of the pattern by making it evaporate due to its heat emission. Thereby, the molten metal replaces the occupied by the pattern thereby getting the desired shape.

II. NON-EXPENDABLE MOLD CASTING

Factors for considering expendable mold casting:

· Reusable

· Dimensional accuracy

· Good heat conductors

Types of Non-Expendable Mold Casting:

1. Permanent mold casting:

This process involves strong and re-usable molds. During this process, a metal core tool that has the output design engraved on it, with a mixture of sand and resin. The heated metal core tool melts the resin and sand mixture. The molten mix cools down for solidification. The casting suppliers remove the solidified mix from the tool. This solidified mix is known as the Fused core.

The casting suppliers place the cores in the permanent mold gravity tool. On closing the tool, they fix the feed system. Following this, they pour the molten metal into the tool. Once the metal solidifies, the casting suppliers remove the feed system and then take the casting out of the tool. They also remove the fused core through vibration.

2. Die Casting:

The mold used in this casting has the pre-designed pattern of the desired metal product engraved on it. This set up is known as ‘Die’. During this process, casting suppliers pour the molten metal into an injection barrel and fused into the mold. The metal solidifies inside the mold.   Finally, the suppliers use rods or pins eject them.

3. Centrifugal casting:

This process is suitable to cast metals in the rotational and symmetric axis with fixed specifications requested by the customers. Hollow metal tubes are cast using this process.

4. Continuous casting:

This process is suitable when large batches of constant cross-sectional metal products is a requirement. During this process, casting suppliers pour the molten metal into a copper mold. The resultant strands of metals pass into roller chambers where water sprays are employed to cool them down. Following this, casting suppliers cut the metals into the desired size.

Essentials to consider before sourcing for casting suppliers:

When you involve in the procurement of casting, it is necessary to ensure that your supplier sourcing depends very clearly on the right process required for your product. In the procurement cycle of the Metalworking market, the right supplier discovery is a key challenge. When you choose suppliers, make sure:

• The supplier serves your location.

• Confirm if your metal needs a one-time or a re-usable mold.

• Check for the chemical properties of the mold and ensure that it does not affect your output casting.

• The best supply chain management equates to the best quality. Choose the suppliers with the capabilities of producing the best in the market.

• Go ahead with expendable mold casting if you choose to go with the cost-effective casting process.

• Select non-expendable casting if you are looking for intricate and precise output.
