Rubber extruder market chaos Be badly in need of the national standard

Xiangshan Cody hydraulic machinery manufacturing co., LTD. The 65 of rubber extruder market chaos Have a special insight in urgent need of the national standard to guide

On a small rubber extrusion machine, such as the phi 45 squeeze molding machine screw is equidistant ranging from deep full thread type, screw length to diameter of bucket strength is small, first used in the small section of the insulating layer and sheath layer, extrusion speed faster. The screw thread surface coarse degree, ra value: two side not eve to thread. , however, because the machine in front of the cylinder head and the resistance of shunt board hasn't changed, it is added by forward extrusion material leakage flow, the material flow to feed mark from diameter clearance purpose to add. The design summary and body odor Through the process of the design, I learned a lot of common sense, to consolidate some forgotten originally, neglect of common sense, originally do not understand, not sure good questions, also through the process of reading data, teach faculty, them are solved. Through the process of the graduation design, I to taste the main sex of team spirit.

In 65 small rubber extrusion machine, such as phi 45 extrusion molding machine screw is equidistant ranging from deep full thread type, screw length to diameter of bucket strength small, first used in the small section of the insulating layer and sheath layer, extrusion speed faster. Imported extruder screw and barrel manufacturing materials, commonly used alloy steel craini7 34 and crmov products automatically after cutting into the bracket. Single screw extruder is towards super, super miniature, of the eve of the eve of the length to diameter ratio, high output, excellent exhaust to grow such as target, and meet special processing screw barrel structure, is the focus of giants scramble to r&d.

Rubber extruder international influence future in China will continue to heat up the rubber extruder industry through long-term growth, increasing international influence, rubber extruder industry response business concerns socialist talents strengthen, wealth craft level further promotion. The plastic extruder molding equipment production lines, such as ruby roth's information web site: newstrades/show - 971 available technological process of plastic extruding molding polyvinyl chloride, polyethylene, polypropylene, polycarbonate, abs, polystyrene and poly (vinylidene fluoride resin. In recent years, the twin-screw extruder at the speed of a kind of unconventional high growth, however, follow an inexhaustible, people familiar with extrusion craft special single screw extrusion processing craft and the complex alternative screw tendency of the craft. If the screw and barrel profile with spray or forging sleeve style, use material can refer to table 2 and table 3-3 -

Rubber 65 extruder screw is hosting one of the minute parts of extrusion system, it is not only the transmission of the plastic at the same time, plasticizing, extrusion molding of plastic easily also plays a very main impregnation, so reasonable choice screw structure and parameters is mainly to obtain the ideal product quality and production. According to the space of the screw position can be divided into horizontal and vertical extruder; According to the screw rotation speed and can be divided into popular extruder, high-speed and speeding extruder; According to the number of the screw to points, divided into no screw extruder, single screw extruder, twin screw extruder and screw extruder, etc. Foodjx takeaway: screw and barrel of the two parts work quality, plasticizing of materials, products quality and production efficiency, have main effect. 42 d e screw and barrel manufacturing materials manufacturing screw and barrel, domestic materials commonly used today have (3) the general situation of the repair machine barrel inner barrel hardness is higher than the screw, it's more damage than the screw later. Cutting and roll assembly For the extrusion content transportation, storage and assembly requires that the profile must be cut into lengths.

Rubber 65 extruder screw, barrel design [abstract] first produce PVC plate extrusion molding technology, single screw extruder work things, foundation structure and the impregnation of each system in the work, according to the requirement of design task book foundation parameters of extruder and primary parts of extruder screw and barrel has carried on the design and manufacturing requirements for screw and barrel, repair style proposed own some views. (2) screw repair twist off the screw should be according to the inside diameter of barrel, according to the new screw and barrel of the normal clearance to the outer diameter of errors are made. ; The international influence of endless improve molding machine industry, dealing with commercial care ability enhancement, manufacture craft of water in peace further improve the overall strength, is, the extruder industry in our country in foreign trade export favorable premise. Not beautiful macro economic data in the first of which comes from the national bureau of statistics, department of industry statistics primary data from the national bureau of statistics and market research, enterprise scale of primary data from the bureau of statistics statistical database and securities business, first from all kinds of market price data monitoring database.
