Castor manufacturers common type of plastic and steel plate thickness

Castor manufacturers common type of plastic support plates and the thickness of the common types of plastic ABS castor castor: name of general engineering plastics, can be used for fitting, backrest, plate, it is a plastic electroplating ( Water plating) The main raw material. The generic names of polypropylene PP casters: used for the five-star feet, armrest, floor MATS and low strength requirement of the connector. Disadvantages: poor abrasion resistance, low surface hardness. PVC castor: common name is polyvinyl chloride (PVC), mainly used for sealing side parts and insertion condition. PVC material is suitable for extrusion molding, plastic parts of non-combustible material, processing and molding temperature stability is poor, especially the color stability is bad. PU castor, commonly known as polyurethane. Mainly used for armrest ( Foam) Accessories. The generic names of POM castor: steel. Mainly used for MATS, castor, door hinge, hinge, such as wear parts. Wear-resisting performance, compression, but the dimension stability is poor. PA castor: generic names of nylon. It is mainly used as high wear resistance and life place, such as floor MATS, the five-star claw and castor. Features: wear-resisting, withstand voltage, high strength indoor and long service life, PA66 individual models of up to 2200, high temperature resistant performance of defect is easy to change the sun sun, easily broken, bad weather. Organic glass (PMMA castor: Commonly known as acrylic acid) 。 Five kinds of transparent plastic material, PMMA is one of the most transparent material. With acetic acid taste, cutting the workpiece processing deformation easily. Can shape bending with boiling water. Disadvantages: easy cut surface, the hardness is low, warped easy craze, the price is 20% higher than ABS. PC castor, commonly known as the polycarbonate. This variety is also a kind of transparent material, high surface hardness, scratch resistance, strong impact resistance, high strength and good weather resistance ( That is not afraid of the sun) 。 Furniture in the shielding plate solar panels is the hollow extrusion molding of the material. Features: high price, about 40% higher than PMMA. Castor manufacturers caster board is flat steel caster stents, has wide aspect ratio and large surface area. According to the thickness of the thin plate and thick plate, castor board is divided into two kinds of specifications. Caster and the thickness of the steel plate is made by the method of hot rolled or cold rolled in 0. Castor between 2 and 4 mm steel plate. The width of the thin castor board between 500 and 1400 mm. According to the different application, the thin casting steel billet rolling by different material. Commonly used materials have carbon steel, high quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used for automobile industry, aviation industry, enamel industry, electrical industry, machinery industry etc. In addition to direct delivery after rolling, casting thin steel plate after pickling, zinc and tin plating processing. Thick castor steel thickness is 4 mm or greater is the floorboard of the caster wheel steel. In practice, a thickness of less than 20 mm of caster wheel steel plate is often referred to as the middle plate, thickness & gt; 20 mm and 60 mm iron called thick plate, thickness & gt; The castor 60 mm. Special plate mill is needed in the steel rolling, so called thick plate. Castor manufacturers casters thick steel plate width of 0. 6 to 3 mm. 0mm。 According to the application of thick plate is divided into castor steel plate, ship bridge castor steel plate, steel plate, boiler caster castor high pressure vessel steel plate, pattern caster wheel steel, automobile caster wheel steel, armoured castor plate and composite castor iron plate. Is a branch of castor plate steel band, it is actually have very long sheet of relatively small width and volume (usually in the Also known as the zone) Supply. Steel belt is usually on the multi frame continuous rolling mill production. After the cut into fixed length, strip steel belt, thus productivity is higher than the single chip microcomputer of productivity.
