Forged Technology and  Cast Technology on spray gun

With the upgrade of the company's technology and the improvement of the company's manufacturing capacity, the manufacturing of the pneumatic spray gun body of Zhejiang Rongpeng Air Tools Co., Ltd. has been upgraded from the earliest casting process to the current forging process. Rongpeng peoples have been working hard to bring airtightness to everyone. The high-lever spray gun with better performance, finer atomization effect and longer service life, then why the forged air spray gun has such good performance, we can understand what is forging, what is casting,

Forged Metals vs Cast Metals

Forging and casting are two different manufacturing processes used to manipulate the shape of metal. The casting process involves heating the metal until it liquefies and then pouring it into a mold to form the desired shape, while forging involves heating the metal until it is malleable but still solid, then pressing or hammering it into a specific shape.

The type of metal fabrication process you choose for metal parts and assemblies will depend on the desired strength and level of detail of the final product.

When to use forged metal parts

In general, if your component can be faked, it should be. Unlike when metals are melted, forging maintains a tight grain structure and a mechanically strong product without the use of expensive alloys. According to a study conducted by the Department of Mechanical, Industrial and Manufacturing Engineering at the University of Toledo, forged parts have 26% higher tensile strength and 37% longer service life than cast parts.

Forged metals are used for parts that need to withstand high impact and mechanical forces, as well as high loads, stresses and wear resistance.

Metal forging method

The most common metal forging methods are open-die forging, closed-die forging, and roll forging.

Open die forging is used to produce larger parts with simpler shape designs, such as rings, bars and hollows.

Closed die forging is used to produce small metal products such as fittings, lifting and rigging hardware.

Roll forging is commonly used to produce parts for the automotive industry, as well as hand tools and knives.

When to use cast metal parts

If your metal parts have many tiny details or internal cavities, they can be difficult to shape during the forging process. In these cases casting will allow the liquefied metal to flow easily into small detail areas. Many metal manufacturers also recommend casting if the part is too large to forge. However, the steel industry is capable of forging parts up to 25,000 pounds.

Cast metal is used for parts with cavities and small details, or parts that require a more difficult to forge alloy.

metal casting method

Modern metal casting falls into two broad categories: expendable casting and non-expendable casting.

Single-use casting uses temporary, non-reusable molds made of sand, loam, plastic, shells, plaster, or lost wax.

Non-consumable casting refers to molds that can be reused, including permanent mold casting, die casting, semi-solid metal casting, and centrifugal casting.

How to choose a metal fabrication method

When we know so much about forging and casting, when we choose spray guns again, you will know why forged spray guns are much more expensive than cast guns, because forging process requirements are high, and the production of pneumatic spray guns The tightness is required, the atomization is stable, and the life is long. When you buy two or more cast pneumatic spray guns, in fact, you only need to buy one forged spray gun, which can actually save a lot of money.
