Rubber Pre-Forming Extrusion Line

Time：

2021-08-06

The rubber pre‑forming extruder mainly consists of a plunger‑type extrusion unit and a die‑mounted rubber‑blank cutting device, complemented by hydraulic, vacuum, heating, pneumatic, and electrical systems. During operation, the die is opened, preheated and rolled rubber compound is loaded into the front of the barrel, and the die is closed. The extrusion and cutting speeds are adjusted, and the desired blank weight is set; computer‑controlled closed‑loop feedback ensures precise blank weights. The rubber pre‑forming extruder is a highly accurate, high‑efficiency machine for producing rubber blanks. It can extrude various strip‑shaped, annular, and three‑dimensional complex blanks with medium to high hardness, delivering blanks of excellent dimensional accuracy and free of air bubbles—making it ideal for manufacturing rubber components, small tires, oil seals, O‑rings, tennis balls, valve stems, shoe soles, automotive parts, and more. A cold‑feed rubber extruder can also serve as a rubber pre‑forming extruder when equipped with a specialized die, cooling water tank, multi‑ribbed belt puller, length‑cutting device, and other auxiliary equipment, forming a complete pre‑forming extrusion production line while providing customers with technical support. Hebei Shuangda Rubber & Plastics Machinery Co., Ltd. is a modern enterprise integrating R&D, manufacturing, and sales of complete sets of extrusion machinery for rubber, silicone, and plastics. Its main products include rubber extruders, rubber hose extrusion lines, three‑layer composite sealing strip extrusion lines, silicone sealing strip production lines, plastic sealing strip production lines, plastic profile production lines, plastic pipe production lines, elastomer extruders, and other extrusion equipment, as well as production facilities for engineering seals, automotive seals, wire and cable components, air‑conditioning hoses, braided tubes, automotive hoses, waterstop strips, and related products.

The rubber pre‑forming extruder consists primarily of a plunger‑type extrusion unit and a die‑mounted rubber‑slug cutting device, complemented by hydraulic, vacuum, heating, pneumatic, and electrical systems. During operation, the die is opened, preheated, rolled rubber compound is loaded into the front of the barrel, and the die is closed. The extrusion and cutting speeds are set, and the desired slug weight is programmed; with computer‑controlled closed‑loop feedback, the target slug weight is achieved.

The rubber pre‑forming extruder is a high‑precision, high‑efficiency machine for producing rubber blanks. It can extrude various strip‑shaped, annular, and three‑dimensional complex rubber profiles with medium to high hardness, delivering blanks of exceptional dimensional accuracy and free of air bubbles—making it ideal for manufacturing rubber components, small tires, oil seals, and more. O Products such as O-rings, tennis balls, valve stems, shoe soles, and automotive parts.

The cold-feed rubber extruder can also serve as a rubber pre‑forming extruder. By installing a dedicated die head and integrating it with a cooling water tank, a multi‑ribbed belt puller, and a length‑cutting unit, it can be configured into a complete rubber pre‑forming extrusion line, backed by comprehensive technical support for customers.
