When talking about rubber products manufacturing, there are various manufacturing processes that do exist. Every procedure has certain benefits, which makes it the perfect choice for the manufacturing of certain kinds of product. You are going to have clearer understanding of tradeoffs and cost implications by simply learning the different manufacturing procedures.

Few of the commonly used rubber products manufacturing include extrusion, molding, latex dipping as well as calendering.

Extrusion -for this procedure, it begins with unvulcanized compound which is later fed to the extruder. After it's inside the extruder, it'll be carried forward to the day; a specialized manufacturing tool to mold the rubber. When the compound reached the dye, the pressure will be forcing it through the opening of the extruder. The extruded product then has to be vulcanized before it can be considered usable.

Latex dipping - this occurs when thin walled mold is dipped into latex compounds and gradually withdrawn. Re-dipping the product in the latex compound will increase the thickness of the dipped product. This product will only be finished by vulcanization as soon as the dipping process has occurred. Depending on finished dipped product, it may require post treatments.

Molding - this composed of three primary manufacturing processes including transfer molding, injection molding and compression molding. The oldest and least expensive technique is the latter. A blank or chunk of rubber is used in this procedure to form the rubber compound. The blank gets placed into mold cavity for it to be shaped. Because of its slow heating time, the curing time takes a while. The heating may vary from 90 seconds for thin walls to few hours for thicker walls.

Transfer molding is the natural progression in development to be able to limit the drawbacks of compression molding. The procedure begins with a blank being loaded in chamber. Once done, it's scattered in several cavities. In early stages, preheating takes place in rubber which forces the rubber to flow through channels. Through this, the curing time is reduced and the rubber can flow easier to fill in mold cavities with improved efficiency. Learn more here..

For rubber products manufacturing, injection molding is the most common procedure used. With this procedure, the press units as well as injection unit function as separate entities which come with a separate control as well. Through this form of molding, there are no blanks handling and the process can be automated while the difficult cavities as well as flow channels can be easily filled.

Calendering - this functions by forcing the softened material to center of counter rotating rollers. The rollers will be compacting the materials while the product's overall thickness is set by the gap distance between the cylinders
