We mainly produce high precision screws and barrels.
According to the different screw structure and thread geometry, the screw can be divided into ordinary screw, new screw and Extruder Screw.
1. Exhaust type screw A special type of screw specially designed to smoothly remove the air, volatile gas and water vapor in the extruded material.
2. The difference between the new type of screw and the ordinary type of screw is that: some non-threaded components are placed on the threaded part of the screw, such as adding a round pin or adding a different thread from the original thread to improve the plastic. The effect of mixing and plasticizing improves the quality of melting and plasticizing of materials, shortens the extrusion time, and increases the production volume.
3. Ordinary Screws One of the most used and most common types of screws is widely used in various types of extruders. According to the pitch and thread depth on the screw, it can be divided into equal thread pitch and thread groove depth type, thread pitch and thread groove depth of the same type and thread pitch, thread groove depth are not equal to the type of screw.
Standard injection screw General injection molding machine should use standard pitch diameter screw, matched with two high and low pressure conventional screws, widely applicable to the manufacturing of general-purpose plastics and engineering plastics.
Extended injection screw It is a universal type injection screw, which has good plasticizing capacity and compounding performance. The features: high draw ratio (20 - 25), long metering section (30%), light groove in metering section (0.04 - 0.05D), high compression ratio (0.11 - 012D).
