The remarkable feature of the split-type parallel-parallel twin-screw extruder is that the barrel can be split at the same time, and the screw and the inner liner of the barrel can be combined at will.
1, split barrel
The conventional twin-screw extruder barrel was monolithic and could not be opened. The split type twin-screw extruder is of a split type, which consists of upper and lower halves of the barrel, the lower half of the barrel is fixed on the frame, and the upper half of the barrel is connected to the lower half of the barrel by a worm gear reducer. Usually, the upper half barrel and the lower half barrel are bolted with two rows of bolts. When the barrel needs to be opened, simply loosen the bolt and turn the handle of the worm wheel box to open the barrel.
2, building block screw and barrel
The screw and barrel of the split-type twin-screw extruder mainframe adopt advanced "building block" design. The screw is composed of various types of screw blocks set on the mandrel. The inner bushing of the cylinder body is based on the screw. The different blocks can be adjusted to flexibly combine the ideal thread element structure according to the material requirements such as material variety, and realize various processes such as material transportation, plasticization, refinement, shearing, exhausting, building pressure and extrusion. Therefore, the contradiction between the so-called screw versatility and the speciality which is generally difficult to balance is well solved, and the purpose of multi-purpose and multi-function is achieved. Another advantage of the "building block" design is that the screw and barrel components that are worn out can be partially replaced, avoiding the scrapping of the entire screw or barrel, greatly reducing maintenance costs.
l, the main machine twin-screw is high-speed co-directional meshing type, which can produce very strong and complicated material transfer exchange, shunt blending and shear kneading in various thread and mixing components. These effects can be fully controlled by changing the screw configuration and operating process conditions to meet the requirements of various processes.
2, accurate measurement, reasonable feeding method is the key to strict implementation of the formula, but also the first level to ensure product quality, we have a variety of feeding methods according to the performance of the material, the user's needs, such as volume measurement, dynamic weight loss Metering, etc., to meet the needs of different products.
3. Advanced control system. The extruder is equipped with an advanced and beautiful control system, and most of its control components are imported components with good quality and high sensitivity. The operating parameters of the main engine such as current, voltage, temperature and torque are very intuitive, so it is very convenient to operate and the requirements for the operator are not high.
4. The system is equipped with several kinds of dicing methods such as drawing water-cooled pelletizing, hot-cutting water-cooling, and hot-cutting air-cooling. Can be configured according to different materials and user requirements

Plasma Cutting Machines are machines that process metal materials by means of plasma cutting technology.
Plasma Cutting Machine structure:
1. The frame adopts all-welded structure, which is firm and reasonable, easy to operate and durable.
2. Plasma Cutting Machine with cutting speed and high precision. The cutting mouth is small, neat and has no slag. On the basis of the traditional numerical control system, the control method for cutting is improved, and the secondary dressing processing is avoided.
3. Plasma cutting machine suitable for low carbon steel, copper, iron, aluminum, galvanized, titanium and other metal plates.
4. The CNC system configuration is high. Automatic arc ignition, stable performance, the success rate of arc ignition is more than 99%.
