Development Prospects of Rubber Extruders

Since its introduction in 1870, the rubber extruder has undergone more than a century of development, progressing through three major stages: hot-feed extruders, cold-feed extruders, and screw‑type cold-feed extruders.

Control system of a rubber extruder

The rubber extruder is a fundamental piece of equipment in the rubber industry and one of the key machines that significantly influences product quality. It plays an extremely important role in the development of tire and rubber‑product manufacturing. Overseas, the evolution of rubber extruders has progressed through stages including plunger‑type extruders, screw‑type hot‑feed extruders, cold‑feed vented extruders, pin‑type cold‑feed extruders, and composite extruders.

The Development Process of Rubber Extruders

A Brief History of the Rubber Extruder The rubber extruder originated in the 18th century; a manual piston‑press manufactured in England in 1795 for producing seamless lead pipes is regarded as the world’s first extruder. Since then, during the first half of the 20th century, rubber extruders were primarily used to manufacture lead pipes, process pasta and other food products, and serve the brick and ceramics industries.

Working principle of a rubber extruder

The working principle of a rubber extruder: In our daily lives, we encounter numerous rubber products—car tires, for instance, are made of rubber, as are many other everyday items. Many of these products can be manufactured in a single step and are widely used in our everyday routines. Some shoe soles are also crafted from rubber. During the processing of rubber, a rubber extruder is required—a specialized machine designed to extrude rubber into desired shapes and forms. Now, let’s explore the operating principles and classifications of rubber extruders.

Development Trends of Rubber Extruders

The meshing zone of the screw elements in a rubber extruder exhibits a significant velocity gradient, which facilitates thorough mixing of the material within this region. Along the axial direction of the screw, the rubber extruder is divided into an feeding section, a conveying‑mixing section, and a discharging section.

Current Status of Rubber Extruder Development

China’s annual output of rubber extruders is close to 80 units, with major production centers located in Qingdao, Guilin, Inner Mongolia, Shanghai, and other regions. Although numerous domestic enterprises have mastered the design and manufacturing technologies for rubber extrusion machinery, only four to five companies currently possess robust R&D and design capabilities, wielding significant influence within the industry. In the mid-1980s, BET and TR introduced and began applying their triple‑compound extrusion and double‑compound extrusion technologies in China.

Components of a Plastic Extruder

In plastic extrusion equipment, the plastic extruder is typically referred to as the main machine, while the downstream auxiliary equipment that works in tandem with it is called the auxiliary machine. Over more than a century of development, plastic extruders have evolved from their earliest single-screw, multi-screw, and even screwless designs. These extruders can be paired with various plastic‑forming auxiliary units to create diverse extrusion production lines, enabling the manufacture of a wide range of plastic products. Consequently, both today and in the future, plastic extrusion machinery will remain one of the most widely used types of equipment in the plastics processing industry.
