Metal HingeCustom

Metal HingeCan be divided into no torsion and torsion type

The so-called no torsion, such as the hinge of the storage box, and so on, do not need to spend too much effort to open. Advantages for the production of simple;The disadvantage is that it cannot remain fixed at a certain angle.

The so-called torsion, you can keep moving parts at any time, to maintain a fixed angle, such as notebook computer and LCD screen, so that users can easily adjust the most appropriate angle can be maintained for a long period of time fixed.

Torsion typeMetal HingeAccording to structural design can be differentiated

Type of heat treatment:

Gas nitriding Treatment:For surface hardness treatment, hardening layer depth is approximately0.005mm

Surface carburizing Treatment:The hardening layer depth is approximately0.25mm

GasketWasher

Type:Dish Type Gasket=Force is forced upon tightening

Oil Storage Gasket=Storage of lubricating oil

Flat Gasket=Friction with oil storage gasket

Material: SK7 (Medium Carbon tool steel)、SUS304 (Stainless steel)

Characteristics: SK7After heat treatment will be elastic, and good wear resistance

Post-processing processing: a) SK7Require heat treatment to increase hardness, hardnessHrc42~45

b)Vibration grinding Deburring

C)Electroplating type:General Nickel

Nylon NutNylonnut

Role:Lock fasteners and prevent loosening

Material: sea/1010, generally referred to as soft steel

Characteristics:Low carbon content, easy to forge

Post-processing processingA)No heat treatment

p.s>Generally has the heat treatment nut, applies in the automobile

b)Electroplating type:Blue-white zinc, black zinc

SpringSpring

Role:IncreaseMetal HingeTorque difference between positive and reverse

Material:Spring steel, the main use of the piano steel wire and black steel line two kinds

Qin Steel Wire=A kind of alloy steel

Black Steel Wire=A type of carbon steel that can be divided into50C、60C、80C

p.s>Price comparison of Qin steel wire:

Sid>Japan>Taiwan>Mainland>Korea

Post-processing processingA)Heat treatment increases the rigidity of the spring

b)Electroplating type:General Nickel, multicolored

OtherOther

Too Gas strong seal agent

Generally used for nut lock fastening, in order to ensure that the nut loose, so the point into the sealing agent as a safeguard, its strong penetration.

Lubricants

Generally used for gasket friction surface, the main component for a variety of aerospace use of synthetic oil, in accordance with the proportion of the deployment of;Good resistance to high and low temperature.
