1. Thermoplastic Plastics Thermoplastic plastics soften when heated and harden when cooled, allowing them to be repeatedly molded through heating and cooling processes. They are easy to process and are commonly used for various molding processes like inject...

Plastic molding refers to the process of making final plastic products from polymers made of synthetic resins. Processing methods (usually referred to as primary processing of plastics) include compression molding (extrusion molding), extrusion molding (ext...

Definition of plastic: It is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid. It is a molten liquid during the manufacturing process. Therefore, it can be melted by heating, flowed ...

Cast iron is a general term for a series of alloys mainly composed of iron, carbon and silicon. In these alloys, the carbon content exceeds the amount that can be retained in the austenite solid solution at the eutectic temperature. The carbon content of cas...

The production process of ductile iron mainly includes the following steps: 1.Tempering of hot metal in electric furnace: Refining low-phosphorus and low-sulfur hot metal, and ensuring that the content of carbon, phosphorus and sulfur in the hot metal meets...

Ductile iron pipe refers to the use of more than 18 casting iron by adding a spheroidal agent, through the centrifugal ductile iron machine high-speed centrifugal casting into the pipe, referred to as ductile iron pipe, ductile iron pipe and ductile casting ...

Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. Based on chemical composition and microstructure, cast iron is classified into several main types. Here is a detailed description of each type: 1. Gray Cast Iron Characterist...

The production process of ductile iron pipe is to add alkaline earth metals or rare metals such as magnesium and calcium to the raw materials of ordinary cast iron pipes. The casting process of ductile iron pipes includes continuous casting, hot mold casting...

[Today's cast iron challenges and future development trend] Throughout the global casting production development trend, at present and in the future cast iron is still the most important casting alloy. With technological progress and development, the perform...

With its excellent performance, ductile iron parts can sometimes replace expensive cast steel and forged steel in use, and are widely used in the machinery manufacturing industry. NO.1 Ancient China: In 1981, Chinese ductile iron experts studied 513 ...
