Steel Casting VS Steel Forging

In most metal foundries, steel castings are mainly produced through these several casting processes: investment casting, lost foam casting, vacuum casting, sand casting and coated sand casting.

Sprues in Investment Casting

The purpose of the sprue is to provide a channel for molten metal alloy to reach the mould once the wax has been burnt. The sprues are generally made of wax. The diameter and the length of the sprue depend largely on the size and ...

Lost Wax Casting and Its Common Defects

The lost wax casting process is widely used as it offers asymmetrical casting with very fine details to be manufactured relatively inexpensively. The process involves producing a metal casting using a refractory mould made from ...

Brief Introduction of Investment Casting

Investment casting, also known as the lost-wax process, is one of the oldest metal-forming techniques, spanning the last 5,000 years. The investment casting process begins with injecting engineered wax into high precision dies or w...

Shell Building for Lost Wax Casting

Shell Building is a very important process during lost wax casting and it can influent the quality of the finished casting components. So here in this article we try to explain some more information about this.

Normalizing Treatment of Investment Casting

Heat treatment of investment casting components is very important. To control the steel investment castings with a good mechanical property, there're several announcements on normalizing.

Investment Casting of Different Metals

Precision investment or lost wax castings can be produced with a wide range of metals and their alloys. At precision investment casting foundry of RMC, normally we use the stainless steel, carbon steel, ductile iron, brass & b...

A Detailed and Typical Procedure of Lost Wax Casting

The procedure of lost wax casting method vary from different facotries to some extent due to the real conditions and what they have and what technologies they use, modernly or traditionally. The following are the procedure of inve...

What is Investment Casting

Many customers asked us what was investment casting, now we try to explain more information about it. Investment casting, also known as the lost wax casting methods, is widely used for the fooundmetal industries. This artice...

Dimensional Tolerances for Steel Castings

For the precision steel casting components, dimensional tolerances are selected by the designer or purchaser to make sure that the part can perform its function reliably and fit into its designed location. Assigning dimensions to a p...

Assembly the Wax Tree

1- Select an appropriately sized steel flask. You will need an inch of clearance around your pattern and between the tip of the sprue and the top of the flask. 2- Attach the tree (the sprue, gate pattern assembly) to a piece of mason...

Stainless Steel Investment Castings

Investment (lost wax) casting is a method of precision casting complex near-net-shape details using replication of wax patterns. Investment casting or lost wax is a metal forming process that typically uses a wax pattern surrounde...
