A gasket is a mechanical seal which fills the space between two or more mating surfaces. They are generally
used to prevent leakage from, or into the joined objects while under compression.
A gasket allows “less than perfect” mating surfaces on machine parts where they can fill irregularities.
 
NBR material

Nitrile rubber, also known as Buna-N, Perbunan, or NBR, is a synthetic rubber copolymer of acrylonitrile(ACN)

and butadiene. Nitrile butadiene rubber (NBR) is typically resistant to oil, fuel, and other chemicals— it is more

resistant than natural rubber to oils and acids but has lesser strength and flexibility. It can be attached by ozone,

aromatic hydrocarbons, ketones, esters, and aldehydes.

NBR’s capability to endure a range of temperatures from -40ºC to +108ºC makes it a perfect material for aeronautical

applications. Other uses of nitrile rubber include non-latex gloves for the healthcare trade, automotive transmission

belts, fuel and oil handling hoses, grommets, O-rings, gaskets, oil seals, V-belts, synthetic leather, printer’s roller,

and as cable jacketing.

Quality control

Material Inspection:Storage of all raw materials before the test, and issue a report on the corresponding material

properties, compared with raw material's own property report, two reports property values is consistent, can put in storage.

Model Inspection:After the mold development or mold cleaning finished on the machine, we will test all the specifications

of the mold to ensure that each cavity of the product specifications and quality.

Production Inspection:The production process of the product inspection personnel timing semi-finished product inspection,

ensure the quality of the rationality of technology, defective rate control in a reasonable range.
 

Quanlity Control:The quality inspection department will conduct a sampling inspection of each batch of products
 

Production Full Inspection:The optical inspection machine can ensure the appearance and dimension of the product are

100% qualified.
