Product introduction

Zhoushan Jinfeng Plastic Machinery Co., Ltd. is located in the hometown of China's screw, the country's largest production base for screws and barrels. Is a domestic professional production of XPS foam plate screw extruder, injection molding machine precision sol barrel, parallel screw, conical screw, building block screw, barrel and accessories manufacturers.

Detailed introduction

Design principle of screw barrel for durable injection molding machine :
The main part of the pin screw is an ordinary screw, and the pin can be set in the falling groove of the melting section or the metering section of the screw or a smooth cylindrical surface without a screw groove at the end of the metering section. The pins are arranged in a certain arrangement, which can vary in density and quantity. The cylindrical pin is formed by assembling the pin into the hole of the screw; the square or diamond pin is formed by milling the pin directly on the screw.
If these pins are set in the melting zone, the pins can break the solid bed, disrupt the two-phase flow, stir the solid and liquid phases together, and increase the contact area between the undissolved solid phase fragments and the contained material, and promote Melting. If the pin is set in the melt conveying area, its main function is to divide the material flow, increase the interface, change the direction of the material flow, and rearrange the flow beam. Diverted and merged many times to change the flow direction and make the melt composition and temperature uniform.
The mixing section is an inwardly grooved structure provided at the end of the ordinary screw homogenizing section, and its outer diameter is equal to the outer diameter of the screw. The grooves are divided into several groups, and between each group is a confluence area of materials. The materials are divided by grooves, meet at the confluence area, and then divide and merge. The principle is similar to the pin type.
Product parameters of screw barrel for durable injection molding machine : Application: Single screw extruder screw types and uses: ordinary type, gradient type, abrupt type, mixing type, separation type, pin type, exhaust type, barrier type, shunt type Corrugated and accelerated screw types are suitable for spinning, granulating, drawing, blown film, extrusion header, foaming, extrusion, sheet extrusion, etc.
We can not only make samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair work on old screws. The service life of bimetal screws is 3-5 times longer than that of ordinary nitriding screws. .
The outer surface is cut with a spiral groove or a cone with a tapered spiral groove. Screws are mostly used in plastic molding equipment, such as plastic profile extruder and injection molding machine. Screw and barrel are the core components of plastic molding equipment. It is the part that is plasticized by heating and extrusion, and is the core of plastic machinery. Screws have different heads and can be divided into external hexagon screws, large flat screws, internal hexagon screws and so on.
