Casting is a process with many interlacing systems and parts: production, material reclamation, packaging, and so on. There are many moments during these processes in which castings can get damaged. But casting damage can easily be prevented by using the right sand casting equipment, and by having the correct safety and maintenance strategies in place.

The importance of high-quality, clean equipment

Castings are shaped by molds often using sand and bonding agents. Molds alone have many factors that influence how the casting will be shaped and formed. If any part of the process is not well constructed, it can cause damage to a casting. For example, if the gating system that brings the molten metal to the mold cavity is faulty, it can affect the integrity of a mold and can be hazardous if molten metal escapes the sprue. Or, if a core is made from poor molding sand, it can be difficult to extract the pattern from the mold.

Using heavy-duty, high-quality equipment reduces the risk of safety hazards and damage. Frequent and consistent maintenance for sand casting equipment makes production and reclamation run more smoothly and efficiently.

The role poor-quality sand plays in damaged castings

In the casting process, sand is mixed with clay to form a bonding agent around a pattern of a product. Once a mold is split apart and the pattern removed, the mold halves are put back together to be filled with molten metal. After the metal cools, the mold is opened and the sand is removed after the casting is taken out. This sand can be reclaimed and reused multiple times. However, if sand is reconditioned at an excessively hot temperature, it can be difficult to control as the physical properties of sand grains can change during the casting process.

A controlled cooling system can cool sand efficiently, with minimal damage to the sand grains. Returned sand is less likely to be conditioned at an overly high temperature. Quality of reconditioned sand will be higher and more consistent, making for better castings and preventing damage to future pieces.

The Metal Casting Process Explained

What is Metal Casting? Metal casting is a modern process with ancient roots. In the metal casting process, metal shapes are formed by pouring liquid metal into a mold, where it is cooled and later extracted from the mold. Metal casting is arguably the earliest and most influential industrial process in history. It’s used to […]
