Product Description

engineering plastic nylon rack gear PA PA66 gear rack and pinion
Mc nylon means monomer casting nylon, is a kind of engineering plastics used in comprehensive industries, has been applied almost every industrial field. 
The caprolactam monomer is first melted, and added catalyst, then poured it inside moulds at atmosphere pressure so as to shape in different castings, such as: Rod, plate, tube. The molecule weight of mc nylon can reach 70, 000-100, 000/mol, 3 times than PA6/PA66. Its mechanical properties are much higher than other nylon materials, such as: PA6/PA66. Mc nylon plays a more and more important role in the material list recommended by our country. 

Since the end of 1980’s, HangZhou engineering plastics industireis company has devoting herself on developing the technology of mc nylon modification, greatly extended the applications in different industries. Basing on the mc nylon, reinforced with variety of additives during the reaction, such as lubricant, molybdenum disulfide, graphite glass fiber, carbon fiber etc, to improve the properties, higher performance of wear-resistance, corrosion-resistance, self-lubrication, vibration-absorption, noise-absorption. At the same time, as the technics and structure of the moulds is quite simple, so that it can be manufactured in lower cost, becomes the ideal substitutes of bronze, stainless steel, babbitt alloy, PTFE and so on. 

Oil nylon (green)
Oil nylon(green)is the new engineering plastics that developed by HangZhou engineering plastics industireis company in the later 1980’s by importing the advanced technology from nylacast Co., Ltd, UK, was the first authentic lubricating nylon that builds the liquid lubricant system during the processing stage, which makes its coefficient of friction is 50% lower than the general PA6 or PA66, the wear-resistance is 10 times than the general ones. Oil nylon is specially developed for the parts of non-self-lubrication, heavy-loading and low-speed-running, which obviously resulted in a substantial increase in bearing life- 5 times that of general PA6 and 25 times that of phosphor bronze! The lubricant contained within the material will not drain, adsorb or dry out and never needs replenishment. The uniform distribution of the lubricant throughout the product guarantees the constant performance of the parts over the whole service life and improvements in rate of wear, sliding frictional properties, abrasion resistance and stick slip performance, which are just a few of the benefits offered by this material. Oil nylon has been successful in considerable enlarging the application of nylon in many industries and specifically for some un-lubricated running parts.

Can plastic gear racks withstand variations in environmental conditions?

Plastic gear racks are designed to withstand variations in environmental conditions to a certain extent. The ability of plastic gear racks to withstand such conditions depends on the specific plastic material used and the nature of the environmental factors involved. Here’s a detailed explanation of how plastic gear racks can handle variations in environmental conditions:

  • Temperature: Plastic gear racks have different temperature resistance capabilities based on the chosen plastic material. High-performance plastics like nylon, polyacetal (POM), or polycarbonate (PC) offer good temperature resistance, allowing them to operate effectively within a wide temperature range. However, it is important to consider the temperature limits specified by the manufacturer for the specific plastic material to ensure that the gear rack can withstand the anticipated temperature variations without experiencing dimensional changes or loss of mechanical properties.
