4 Common Types of Rubber Products Manufacturing


There are a number of manufacturing processes applied when talking about rubber products manufacturing. Every procedure has its own benefits, making it the best choice for manufacturing of particular types of product. Making yourself aware of the different manufacturing processes can help you to have better understanding of trade-offs and cost implications.

Some of the frequently used rubber products manufacturing are extrusion, molding, latex dipping as well as calendaring. Click for these types.

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. The pressure forces it through extruder’s opening as soon as the compound reached the dye. The extruded product will be vulcanized before it can be deemed 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Latex dipping – this occurs when thin walled mold is dipped into latex compounds and gradually withdrawn.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. When the dipping process has occurred, the product is now finished in vulcanization. Post treatments may be required depending on the finished dipped product.

Molding – this composed of three primary manufacturing processes including transfer molding, injection molding and compression molding. The latter is basically the least expensive and oldest method. 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 actually the natural progression in development in order to limit drawbacks of compression molding. This procedure starts with blank being loaded in chamber. After that, this is distributed in multiple cavities. In the early stages, the preheating starts in rubber which will force it to flow through channels. This will help in reducing the curing time and also, lets the rubber to flow easier and fill in mold cavities with higher efficiency.

Injection molding is a common process for rubber products manufacturing. With this kind of procedure, the press units and the injection unit serve as separate entities which come with individual controls too. With this type of molding, there is no blanks handling and processes may be automated and the difficult cavities as well as flow channels can be easily filled.

Calendaring – this one functions by forcing softened materials to center of counter rotating rollers. The rollers are compacting the material and the overall thickness of product is set by the gap distance between cylinders. Visit here https://sternrubber.com/.
