Nylon rod manufacturing process and production process

Nylon rod is a common engineering plastic product with strong physical properties and chemical stability. It is often used in machinery manufacturing, electronic appliances, automobiles and other fields. The following will introduce the manufacturing process and production process of nylon rod.

The manufacturing process of nylon rods mainly includes raw material preparation, melt extrusion, cooling and solidification, cutting and post-processing.

First of all, raw material preparation is the first step in making nylon rods. Commonly used nylon raw materials are nylon 6 and nylon 66, which are polymer compounds synthesized by polymerization. During the manufacturing process, it is necessary to prepare an appropriate amount of nylon raw materials and mix them according to the formula ratio.

Next, the mixed nylon raw materials will be fed into a melt extruder. The melt extruder heats the nylon raw materials to a molten state through heat and pressure. In the molten state, the nylon raw materials become viscous and can be extruded into continuous nylon rods through the extruder's screw.

The extruded nylon rod passes through the die mouth of the extruder and enters the cooling and curing stage. During the cooling and curing process, the nylon rod will be rapidly cooled by cooling water or cold air, so that it changes from a molten state to a solid state. The speed and temperature control of cooling and curing have an important impact on the quality and performance of the nylon rod.

After cooling and solidification, the nylon rods will be sent to the cutting machine for cutting. The cutting machine will cut the continuous nylon rods into the required length according to the required size and length. The cut nylon rods will be collected and prepared for subsequent processing and use.

Finally, the cut nylon rods need to be post-processed. Post-processing includes deburring, polishing, inspection and other links. Deburring refers to removing burrs and uneven parts on the surface of the nylon rod to make its surface smoother. Polishing is to improve the gloss and appearance quality of the nylon rod. The inspection link is to conduct quality inspection on the nylon rod to ensure that it meets the relevant standards and requirements.

Through the above manufacturing process and production process, nylon rods can be stably manufactured. This engineering plastic product has strong physical properties and chemical stability and is used in various fields. When using nylon rods, it is necessary to pay attention to its use environment and temperature range to ensure its normal operation and extend its service life.
