Needle valve manufacturers recommended, needle valve hot runner system introduction

Needle valve belongs to a relatively special throttle valve, because it has a high degree of regulation accuracy, and the production process is also very reliable, so the product plays an outstanding role in many areas, for the amount of knowledge of the friends also know that the throttle valve products on the market are divided into a variety of applications, including the needle valve hot runners and the needle valve hot runner system is even more widely used. Then today for you to give examples of their information, in addition to recommending several reliable manufacturers.

First, the needle valve hot runner

Needle valve nozzle technology is more advanced, the main advantages are:

(1) in the product does not leave a gate residual marks, into the gate traces of smooth;

(2) the ability to use a larger diameter of the gate, which can be made to accelerate the filling of cavities, and further reduce the injection pressure, reduce product deformation. Reduce product deformation.

(3) It can prevent the drawing phenomenon and drooling phenomenon when opening the mold;

(4) When the screw of the injection molding machine is backed up, it can effectively prevent the material from being sucked back from the cavity;

(5) It can be used with the sequence control to reduce the fusion marks of the products.

Because the hot nozzle form directly determines the hot runner system selection and mold design and manufacturing, and thus often corresponding hot runner system is divided into open hot runner system and needle valve hot runner system.

Two, needle valve hot runner system

1. Performance

Valve needle hot nozzle, good color change performance, suitable for most plastics, good fluidity performance, very fine traces of the gate and so on. Valve gate hot runner system plastic mold structure is the most complex. It has the same structure with ordinary multi-head hot runner system plastic mold, in addition, there is also more than one set of valve pin transmission device to control the opening and closing movement of the valve pin. The transmission device is equivalent to a hydraulic cylinder, the use of injection machine hydraulic device connected to the mold, the formation of hydraulic circuit to achieve the valve needle opening and closing movement, control the molten state of plastic injection cavity.

2. Types

This type of hot runner system has a lot of hot tip type and sprue type runner system can not have the advantages. For example, the gate switching time can be artificially controlled, the gate is smooth and flat, and the technical field of hot runner technology application can be expanded.

Three, needle valve manufacturers recommended

1, Shanghai Huanying Pneumatic and Hydraulic Components Co., Ltd. was founded in 2010, mainly produces stainless steel ferrule fittings, quick-twist fittings, pagoda fittings, stainless steel check valves, copper fittings, operating pneumatic components, hydraulic components, quick couplings and other industrial automation products. The products include pneumatic fittings, hydraulic fittings, cylinders, solenoid valves, air hoses, mufflers, hydraulic cylinders, hydraulic valves, high-pressure tubing, oil pumps, and various types of air processors, etc., with complete specifications and high cost performance. And there are professional manufacturers engaged in the design and processing of non-standard parts, to solve all your problems, is the majority of equipment manufacturers, equipment maintenance business, as well as air, hydraulic pipeline engineering and construction of the ideal choice

2, Special Valve Jiangsu Fluid Machinery Manufacturing Co. Located in the modern port city of special valve Jiangsu, currently covers an area of 28,000 square meters, construction area of 12,000 square meters, is a self-supporting import and export rights, set scientific research, manufacturing, sales, service in one of the modern professional instrumentation pipe fittings valve manufacturing company. The company is engaged in the production and development of special valves, including special material valves, special structure valves, valves used in high temperature, high pressure and harsh working conditions, as well as valves used in special media.

3, zhuji city store mouth Fu Chen pneumatic components factory is located in the central part of zhejiang province, is located in the beautiful hometown of xishi - pilot town of urbanization, zhejiang zhuji city store mouth town zhang ginger dock industrial park. Our factory mainly produces starter joints, pneumatic metal joints, pneumatic copper joints and so on. The company has a complete set of production and testing equipment, perfect organization and a group of high-quality professional and technical personnel, the products are strictly in accordance with the ISO9001: 2000 international quality system standards for the production of high-quality product quality is exported to all parts of the country, and has now been for the automated production lines of several famous brands supporting. Series products are widely used in pneumatic, plumbing, gas, air compressor, refrigeration, chemical, food, textile, medical, pharmaceutical machines and other pipeline engineering projects.

The needle valve hot runner and needle valve hot runner system involved above belong to the needle valve peripheral products, they are because of the stable performance, excellent quality and service life performance, and therefore be used in many manufacturing areas, the market is responsible for the products of this kind of manufacturers are also quite a lot, most of them can take into account the reputation of the sales advantage, for example, the three recommended above because of the reliable technology production line The three recommended above, for example, because of the reliable technical production line, perfect after-sales service mechanism, so it is worth consumers to trust the acquisition of manufacturers.
