The density of non-metallic materials is much smaller than that of metal materials such as steel, iron, copper and lead, and some are lighter than aluminum, magnesium and titanium. According to the calculation of specific strength (strength / specific gravity), the specific strength of some fiber resin composites at room temperature exceeds that of high-strength steel and high-strength aluminum. These materials are used to manufacture general light structural parts such as handwheel, handle, support, cover and instrument panel, as well as high-strength structural parts such as aircraft wing and blade, integral boat, automobile body and transmission shaft, high-speed textile heald frame and high-pressure container, which can reduce self weight, increase carrying capacity or improve operation speed and save energy.
Some inorganic non-metallic materials are wear-resistant due to high hardness, such as grinding wheel, abrasive cloth (paper), oilstone, abrasive and cutting tool made of diamond, silicon carbide and corundum, which can be used for grinding and cutting; Some materials have high elasticity and wear resistance, such as rubber tires and transport belts, which can resist the wear of particles such as sediment, ore and coal; Some materials can reduce friction and wear by virtue of their inherent lubrication performance and low friction coefficient. For example, mechanical parts such as bearings, guide rails, piston rings and sealing rings made of plastic, graphite and silicon nitride can operate safely under the condition of no oil dry friction or less oil lubrication, which is particularly beneficial for occasions where grease is avoided or oil lubrication is inconvenient to supply.

For example, rubber, plastic, asbestos and flexible graphite are suitable for manufacturing dynamic and static sealing parts due to their good flexibility and elasticity, such as piston ring, sealing packing, O-ring and V-ring of compressor. In modern times, a sealing material called liquid sealant with resin or rubber as the matrix has also appeared, which is suitable for all kinds of static sealing and easy to use.
Such as rubber, plastics, ceramics, asbestos, mica, glass cloth laminate (a composite material) are widely used electrical insulation materials.High temperature insulation material
For example, refractory materials, asbestos, alumina and refractory fibers have good high-temperature performance and low thermal conductivity. They are suitable for furnace body, lining or insulation layer of high-temperature kilns such as chemical furnace, converter, electric furnace, heat treatment furnace and tunnel kiln to prevent heat outflow; Due to slow heat transfer, plastic has a warm feeling when human body contacts it. It is suitable for manufacturing handwheel, handle, steering wheel and other objects.
Another special use of non-metallic materials is to be used as ablation resistant materials, such as ablation parts for aerospace made of phenolic, asbestos, quartz and other fibers. They can burn, decompose, dissipate heat and carbonize for a long time above 2500 ℃, form a thermal insulation layer and effectively protect the internal structure. In addition, some non-metallic materials have the characteristics of silencing, vibration elimination, light transmission and non-magnetic, which can be used to manufacture parts such as rubber spring, vibration avoidance gasket, optical lens and so on.
The service of this company and the quality of their producuts,it very good! They always answer messages within a few hours. They produce and ship the parts fast,and when the parts arrives,they exactly like you wanted them!I will use this company as my future producer,for sure!very good experence.
The quality and professionalism of this company are very high. We are happy to cooperate with this company. I really recommend this company. Their customer service is excellent. We contacted an account manager. Her name is shy. She's great. Her boss Tosinn is also a great man.
The product arrived very quickly and was well within our desired tolerances. It was a difficult part to machine and they successfully created our prototype! We really enjoy working with Tosinn, they always respond and send quotes quickly.
Very accurate machining with a very nice surface finish (sandblasted) and anodidization It was very easy to communicate with Micheal. I just gave him a STEP file and a simple drawing with the hole call-outs and he did the rest. The parts came out perfect. This is the easiest relationship I've ever had with a machine factry.. I've had over 35000 parts made by Shenzhen Tosinn Precision Technology Co and will continue. This is a very successful cooperation.
I can't say enough good things about Shenzhen Tosinn. I never have to worry about anything because she takes care of it all and she doesn't it quickly. She even replies to you at odd times of the day when she should be asleep or enjoying her weekend. I'm 100% going to keep doing business with Tosinn. Thank you so much! RR
We initially started working with Tosinn, as we needed a high quality product developed within a very short lead time. The entire process went very smoothly and we received the products ahead of schedule. We were pleased with the final results and we found working with Luke very easy, as he offered good technical advice.
