Construction Machinery Steel Closed Die Forging Parts

Maple's Construction Machinery Steel Closed Die Forging Parts are used by construction machinery manufacturers in the United States and Europe. It is the hydraulic cylinder part of excavator, the joint part of excavation manipulator and the part of controlling steering system in large construction machinery. It is the most key part in construction machinery. The Construction Machinery Steel Closed Die Forging Parts of our company are made of high-strength alloy steel, and the production process is advanced metal forging process. The internal materials of the forgings are well organized and free of defects, which can meet the needs of high-strength operation of construction machinery. It is the preferred component for manufacturing high-quality construction machinery.

Product Description

Construction Machinery Steel Closed Die Forging Parts


1.Product Introduction

In Construction Industry, most parts need higher strength and wear resistance. Compared with castings, forgings have higher density and strength. For the same products, the parts produced by forging have longer service life, higher strength and more reliability. On the premise that it can be used, we will more recommend customers to use Construction Machinery Steel Closed Die Forging Parts.

3. Maple’s Service for Construction Industry

 Construction machinery is essential for building purposes and involves loading and unloading of equipment and materials. We use these machineries for road maintenance, landfill, material transportation, and other tasks related to the construction industry. Some widely used machinery and equipment in construction machinery includes trenchers, drills, shovels, excavators, and road rollers. Our customers rely on us to make the most durable and reliable construction machinery.

 Our customers choose us over others for their needs for construction machinery because of our high-quality products and competitive costs. We customize our services to meet customer needs and earn high satisfaction because of the advanced technology and extensive after-sales support.


 MapleMachinery has been offering professional Construction Machinery Steel Closed Die Forging Parts services to our customers for many years now. They rely on us completely because of our professional services and excellent technology and advanced equipment. We can also improve the original forgings, and customers provide process solutions and purchase blanks. It is because of our high-end expertise and in-depth cooperation; we have exported millions of US dollars’ worth of forgings.

4.Supporting Service for Construction Components

 As mentioned above, in order to work in adverse conditions, the performance of the Construction Machinery Steel Closed Die Forging Parts must be excellent. Therefore, it’s not enough to only produce raw castings or forgings, but also need heat treatment, machining, surface treatment, NDT testing, etc.


 Heat treatment: heat treatment is the critical step to improve the mechanical properties of the workpiece. We can formulate the process according to the strength requirements of the parts, and improve the mechanical properties of the parts such as hardness, yield strength, tensile strength and elongation by heat treatment


 Machining: we have our own machine shop, and can complete almost all machining requirements with advanced equipment.


 Surface treatment: the purpose of surface treatment is to make parts work in adverse environment. Zinc plating can prevent parts from rusting; Nickel plating can enhance the wear resistance and corrosion resistance of parts; Phosphating can prevent parts from corrosion…


 Non-destructive testing (NDT): NDT is the last and most important step. Maple will NDT the parts to ensure that there are no surface defects (such as cracks, sand holes, blow holes) and no internal defects (shrinkage and slag) on the delivered parts.

6. Why Closed Die Forging

Compared with casting, forging has its special advantages:

1. In the case of the same material, the mechanical properties of forgings are better than those of castings.

2. The forgings strength is higher and the fatigue resistance is stronger.

3. The forgings has better compactness.

4. There are no internal defects and surface defects.

5. Fast production speed, high efficiency, suitable for mass production of products.

6. The product quality is stable.
