Recommendation of needle valve manufacturer and introduction of needle valve hot runner system
Needle valve is a special throttle valve. Because of its high adjustment precision and reliable manufacturing technology, this product plays an outstanding role in many fields. Friends who know a lot know that there are many kinds of throttle valves on the market, including needle valve hot runner and needle valve hot runner system, which are widely used. So today I will give you a few examples of their information and recommend several more reliable manufacturers.

I. Hot runner of needle valve

Needle valve nozzle technology is advanced, its main advantages are:

(1) There is no gate residue on the product, and the gate trace is smooth;

(2) The larger diameter gate can be used, which can accelerate the cavity filling, further reduce the injection pressure and product deformation.

(3) it can prevent the salivation caused by thread tying during mold opening;

(4) When the screw of the injection molding machine retreats, the material can be effectively prevented from being sucked back from the mold cavity;

(5) It can cooperate with sequence control to reduce product weld marks.

Because the form of hot nozzle directly determines the choice of hot runner system and the design and manufacture of mold, hot runner system is often divided into open hot runner system and needle valve hot runner system accordingly.

Second, the needle valve hot runner system

1. performance

Valve needle hot nozzle, good color change performance, suitable for most plastics, good fluidity, extremely fine gate trace and so on. The plastic mold structure of valve hot runner system is the most complicated. It has the same structure as the common multi-head hot runner system plastic mold, and a set of valve needle transmission device is added to control the opening and closing movement of the valve needle. The transmission device is equivalent to a hydraulic cylinder. The hydraulic device of the injection machine is connected with the mold to form a hydraulic circuit, which realizes the opening and closing movement of the valve needle and controls the injection of molten plastic into the cavity.

2. Type

This type of hot runner system has many advantages that hot tip runner system and pouring sleeve runner system do not have. If the gate opening and closing time can be controlled artificially and the gate is smooth and flat, the application field of hot runner technology can be expanded.

Third, the needle valve manufacturer recommended

Shanghai Huanying Pneumatic Hydraulic Components Co., Ltd. was established on 20 10, mainly producing stainless steel ferrule connectors, quick-twist connectors, pagoda connectors, stainless steel one-way valves and copper connectors, and operating industrial automation products such as pneumatic components, hydraulic components and quick connectors.

And there are professional manufacturers engaged in the design and processing of non-standard parts to solve all your troubles. It is an ideal choice for equipment manufacturers, equipment maintainers and gas and hydraulic pipeline engineering construction.

2. Jiangsu Fluid Machinery Manufacturing Co., Ltd., a special valve, was established in 1993. 20 15 Jiangsu special valve high and medium pressure valve co., ltd changed its name to special valve Jiangsu fluid machinery manufacturing co., ltd. special valve is located in the modern port city of Jiangsu, and currently covers an area of 28,000 square meters, with a construction area of 12000 square meters. It is a modern professional instrument, pipe fitting and valve manufacturing company with self-operated import and export rights, which integrates scientific research, manufacturing, sales and service. The company is engaged in the production and development of special valves, including valves with special materials, valves with special structures, valves used under high temperature, high pressure and harsh working conditions, and valves used under special media.

3. Zhuji Diankou Pneumatic Components Factory is located in the middle of Zhejiang Province, located in the beautiful hometown-urbanization pilot town, Zhangjiawu Industrial Park, diankou town, Zhuji City, Zhejiang Province. Our factory mainly produces starting connectors, pneumatic metal connectors and pneumatic copper connectors. The company has a complete set of production testing equipment, perfect organization and a group of high-quality professional and technical personnel. Products are produced in strict accordance with ISO900 1:2000: 2000 international quality system standards, and are exported to all parts of the country with high-quality products. Now it has been equipped with many well-known brand automatic production lines. Series products are widely used in pneumatic, pipeline, gas, air compressor, refrigeration, chemical, food, textile, medical and pharmaceutical pipeline projects.

The needle valve hot runner and the needle valve hot runner system mentioned above belong to the products around the needle valve. Because of its stable performance, excellent quality and long service life, it has been applied in many manufacturing fields. There are also many manufacturers in charge of such products in the market, and most of them can take into account the advantages of word-of-mouth sales. For example, the three manufacturers recommended above are trusted by consumers because of their reliable technical production lines and perfect after-sales service mechanism.
