Plastic PA6 Gear                         

 MC Nylon means Monomer Casting Nylon(PA6), 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, three 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 1980s, Guangzhou Engineering Plastics Industries Co., Ltd 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.

MC nylon is mainly applied in the field of mechanical engineering, chemical engineering, electric/electronic, auto industry etc, to be made bearing & wear parts and structural parts instead of copper, tin, alloy and stainless steel. Because of the excellent inherent properties ,MC nylon is widely used in different industries, such as: mining, metallurgy, petroleum, construction, textile, pulp & paper, shipbuilding, water and electricity project, environmental protection and water treatment, ocean developing, war industry and so on. It produces the distinct benefit of economy and society.

The profile shapes of MC nylon, such as pipe, tube and plate can be manufactured into the four wear and friction components: gear, sheave, bearing and roller, as well as different kinds of structural component, such as: mechanical seal circle, guide plate, scraper etc.

Pharmaceutical equipment:

MC nylon has the anti-corrosive, rustless and unconglutinant resistances, which are suitable for making gears, rollers guides and other components in pharmaceutical equipment. It is one kind of material that conform the regulations of China GMP and USA FDA.

Water conservancy and environment protection:

Big slide blocks of water conservancy engineering, big wheels of waste water pool, scrapers, grid chain and harrow of feculence filter, dryer roller and other wear components.

Electronic industry

The main application of MC nylon in electronic industry is ESD performance. It has been adopted for the various parts due to its characteristics of protecting electronic components from static damage, such as: chip salver, casters in the clean room, roller of the transportation system of LCD panel assembly line.

Auto industry:

Automobile industry is the biggest applied field of polyamide engineering plastics. MC Nylon can be applied in many parts of the car, such as: cylinder head cover of the engine, air cleaner inlet pipe, as well as the parts of power steering, oil reservoir, fuel strainer and so on. Besides, MC Nylon can be made into the gear for balancing the eddy bearing, which has a higher strength than metal gear, and reduce the noise of car in running.
