The hardware of office furniture

In the office furniture hardware, < span style = "foNt - size: 16 px;"> hardware & throughout; concept is a popular term, standard classification should be divided into ferrous and non-ferrous metal two kinds big, it is used in the furniture with tube, rod, plate, lines, angular.
The black metal piece
office furnitureMainly refers to the iron products, its advantage is: resistance to deformation, high strength, good abrasion resistance, high hardness, low price, long service life.Carbon ferroalloy, it points, high carbon steel, low carbon steel, medium carbon steel;It runs round tube, square tube, Angle steel, steel plate a few classes.Round tube is mainly used for chair products;Party work, bracket beam;Steel plate is mainly used for stage desk of baffle, screen plate, pendant, arm, metal cabinets, doors, etc.
Volume weight "steel disadvantages: easy to rust Afraid of damp,
Methods to solve the defects such as electroplating, spray, black bluing.

"/ >Hardware processing molding methods more: bending, punching, drilling, welding, cutting, pressure.All in all, carry on the processing according to the requirements of the design requirements or product.
Office furniture non-ferrous metal pieces in
In addition to the iron products all the metal parts such as: aluminum, copper, zinc, stainless steel, etc.It has a characteristic of not easy to rust, strength is relatively poor black metal, used in furniture more are: aluminum plate, aluminum rods, stainless steel pipe, stainless steel plate, copper plate, zinc plate.
Stainless steel parts, stainless steel and stainless steel parts points don'tStainless steel two broad categories: often say & other;Throughout 430 &;As the stainless iron, & other;Throughout 304 &;Is pure stainless steel, one of their discrimination methods: use the magnet test, & other;Throughout 430 &;Can be magnet to absorb and & other;Throughout 304 &;We don't.Stainless steel pieces of slightly higher than the proportion of iron products, the price is more than four times higher than iron products, therefore, will only use a high grade product.
Copper products: copper products pure copper and copper alloy.Pure copper is also called copper, poor strength, hardness, good toughness.Should be in copper alloyUsed for furniture more for brass, it is a kind of zinc alloy copper.Pure copper prices slightly higher & other;Throughout 304 &;30 ~ 40%, stainless copper and brass is 20% lower than that of pure copper prices.Copper alloy hardness and strength than stainless copper slightly tall, but easy to fracture, greater brittleness.Application of copper pieces of furniture are mainly handle, embedded screw.In order to prevent & other;Rust & throughout;To use, generally speaking, pure copper plating, and brass is not required, large area is used less in furniture products.
Zinc products: pure zinc products use less, mainly combined with with zinc alloy or steelUse.Such as galvanized sheet, electrolytic plate, etc.Used in furniture is less, the reason for poor strength of zinc products.Zinc alloy accessories such as eccentric buckle, structure connection point (a), etc.The proportion of zinc alloy slightly lower than iron around 6.8 or so, the price between steel and aluminum alloy, the majority of the zinc alloy furniture fittings in the form of die casting production.
Titanium and zirconium alloy: such is the more expensive metals, most of it is used for furniture, occur in the form of plating for high-grade shake handshandle, hinge, and high quality fittings or exposed hotel furniture.Its cost is higher than chromium plating cost around 40%, but the appearance of high-grade products similar to gold and silver, wear resistance is very good, don'tWill rust.

The
casting metal office furnitureThere are many with cast in furniture hardware products, such as the handle, door hinge, etc., the current market popular all kinds of casting production processType a lot, such as precision casting process, die casting process, casting process.Materials for casting brass, tin, zinc alloy, aluminum alloy stainless steel.Casting product features: exquisite, modelling is special, etc.Faults for high unit cost, cost of different casting processes are different, generally high to low, precision casting die casting mould, mould cost is high to low is: die casting precision casting.Faults for casting products: production cycle slightly increased, the product after 2 ~ 3 working procedure to make the qualified parts, and accessories according to different requirements or plating, polishing, wire drawing, sand blasting, fuel injection, etc.
