Screw Design for Butyl Rubber Extrusion Equipment

For rubber sealing strip production lines, there are two main types: single‑extrusion lines and composite‑type lines. Regardless of the production method, the process begins with an extruder to form the seal, followed by a vulcanization step using vulcanizing equipment to produce the final product. Some people ask whether these production lines meet environmental standards. During extrusion, the rubber extruder itself generates no pollution; however, during vulcanization in the curing chamber, a small amount of exhaust gas is produced. By capturing this gas through exhaust ducts and routing it to a plasma‑based air purification system, we can effectively ensure compliance with environmental regulations.

Production Process of Plastic Pipes

When manufacturing plastic pipes, the choice of production equipment and processes must be tailored to the specific type of pipe. There are many types of plastic pipes, and the manufacturing techniques employed depend on the material’s properties and structural requirements. For example, single‑layer flexible plastic hoses have a relatively simple production process. During production, we adjust the raw‑material formulation based on the product’s performance; after mixing in a kneader, the compound is fed into a pelletizing machine to produce pellets. The plastic pellets used for flexible hoses differ from those used for rigid pipes.

Applications of Rubber Filter Press Equipment

A rubber filter machine, also known as a rubber refining machine, is widely used in the production of EPDM reclaimed rubber products. This is because, to reduce costs, we often incorporate reclaimed rubber into the extrusion process when manufacturing rubber goods. However, recycled reclaimed rubber frequently contains impurities such as nylon cords and metal filings. Therefore, before proceeding with production, the rubber must be filtered using a refining machine. As a type of rubber extruder, the refining machine is typically operated using a hot-feed rubber extruder. The extruder’s barrel and screw are preheated to 3… via a temperature-control system.

Production Process of Transparent Sealing Strips

Among the sealing strips commonly used, one type is white and transparent; this is what we refer to as PVC transparent sealing strip. The production process for PVC transparent sealing strips is similar to that of ordinary sealing strips: first, plastic granules are produced using a pelletizing machine to obtain the desired transparent pellets, which are then extruded into the required product shape. However, transparent plastic sealing strips have poor recyclability and cannot be remanufactured from recycled plastic. These strips are made primarily from resin powder, combined with auxiliary materials such as rubber oil and other raw ingredients. These raw materials…

The manufacturing process of rubber hoses

There are many types of rubber hoses, and we need to select the appropriate production equipment and processes based on the specific hose type. For example, single‑layer ERDM rubber hoses can be produced using only a single rubber extruder for extrusion molding. In general, we use pin‑type rubber extruders for this purpose. After the rubber has been processed in a mixer or an open mill, it is fed into the extruder’s feeding system for extrusion. Once the rubber is loaded into the extruder barrel via the feeding system, the temperature begins to rise; as the rubber heats up, its flow characteristics improve and it moves along with the main…
