1. Plunger rubber extruder The plunger rubber extruder originated in the 18th century, and the manual piston extruder for making seamless lead pipes made by Joseph Bramah in England in 1795 is considered the world's first extruder. Since then, within the first 50 years of the 19th century, Extruders...

Rubber extruders play an extrusion role in the production of rubber products. Extrusion molding is a high-efficiency, continuous, low-cost, and wide-ranging processing method, but people mistakenly believe that extrusion molding is a low-precision, low-value-added molding method. With the increasing...

Before starting the plastic extruder, we must first check whether the circuit of the plastic extruder has leakage and whether the rotating part is exposed. Then we start to heat up the equipment. Do not touch the heating system and the screw barrel of the equipment with your body during the heating ...

The rubber extruder plays a forming role in the production of rubber products, so we often call it a rubber extrusion machine. So how does the rubber extruder extrude the product into the shape we need? How does the device work? Before the rubber extruder produces the product, the molding die and di...

There are many types of plastics that can be produced by plastic extruders, and even plastics of the same type of material are produced at different production temperatures. We need to set the setting temperature of the plastic extruder in combination with the formulation of the product and the degr...

Because the air pressure or oil pressure is too low, the automatic screen changing device of the rubber extruder will be slow or even ineffective. In addition, the air leakage and oil leakage of the cylinder and hydraulic station will also cause this problem. Faced with this kind of problem, the ope...

①The machine head should be assembled together and installed on the extruder as a whole. ②Before assembling the machine head, wipe off the grease applied during storage, carefully check the cavity surface for bumps, scratches and rust spots, perform necessary polishing, and then apply a layer of sil...

The function of the rubber extruder is to use heat, pressure and shear to transform the solid plastic into a uniform melt and send the melt to the next process. The production of the melt involves mixing additives such as color masterbatches, blending resins, and regrinding. The finished melt must b...

Rubber extruder plays a role in extrusion molding in the production of rubber products. Many rubber products are inseparable from rubber extruder during production. The types of rubber extruders are classified according to their functions. For example, some rubber products need vacuum exhaust during...

Rubber extruder is basic equipment in the rubber industry and one of the key equipments affecting product quality. It plays a very important role in the production process of tires and rubber products. The development of foreign rubber extruders has experienced plunger extruders, screw-type hot-feed...

1. Classification of extruders Plastic extruders are divided into single-screw, twin-screw and multi-screw extruders according to the number of screws. At present, single-screw extruders are widely used and are suitable for extrusion processing of general materials. The single-screw extruder occupie...

rubber materials have been used by many industries since the 19th century. Since then, different rubber processing methods have emerged but one that remains a preferred choice amongst manufacturers is rubber extrusion. What does the Rubber Extrusion Process Entail? Rubber extrusion is the process of...
