What is the difference between Pc screw and ordinary screw in injection molding machines?

1.There is a significant difference in size between PC screw and ordinary screwWhat is the difference between injection molding PC screws, PC screws are usually designed to be smaller, while ordinary screws are relatively larger. This design difference is mainly due to the characteristics of PC materials. PC, or polycarbonate, has excellent transparency, high heat resistance and mechanical strength. In order to better adapt to these characteristics of PC materials, the hardness of PC screws has also been correspondingly improved.

2. Liquidity, characteristics. Mobility. PC screw is a high-viscosity non-crystalline plastic with poor flowability, while pe screw production is difficult to melt and has strong flowability. Characteristics. PC screw is easy to degrade after long-term heating, has large feeding torque, and has medium and small diameters as pe screw, and has good flame retardant ABS.

3. Different bearing conditions and different forming characteristics. Bear the difference. pcWhat is the difference between injection molding PC screws: High temperature resistance and no deformation under high temperatures. ppWhat is the difference between injection molding PC screws: Good chemical resistance. Different forming characteristics. pcWhat is the difference between injection molding PC screws: High-viscosity amorphous plastic, large feeding torque and difficult to melt. pp: Crystalline material has low hygroscopicity and is prone to melt rupture.

4. In the field of injection molding machines, the choice of screws is crucial to product quality and production efficiency. Different types of screws are suitable for different raw materials to meet specific processing needs. The PC special screw is suitable for high-viscosity plastics such as PC. It has the characteristics of less shear heat and acid corrosion resistance, and has a moderate diameter. This screw is suitable for forming PC, PP-R, flame retardant ABS and other materials, but it has poor color mixing effect on ordinary PMMA products.

The difference between pc screw and pp screw

1. Material: PC screw is made of high alloy steel, such as 38CrMoAlA, which has good wear resistance and corrosion resistance. PP screws are made of stainless steel, such as 304 stainless steel, which has good corrosion resistance. Design: Due to the high melting point of PC materials and high melt viscosity, the design of PC screws should consider higher torque and extrusion pressure to ensure that the material can be fully melted and extruded. PP materials have low melting point and melt viscosity, so the design of PP screws can be simpler.

2. Different types of plastics have significant differences in core requirements for injection molding screw parameters, and need to be configured according to material characteristics. The length-diameter ratio of polyethylene (PE) is controlled between 20-25, which can fully plasticize and avoid material degradation; the compression ratio is recommended to be 5-5 to adapt to its low viscosity; the depth of the screw groove adopts the depth of the feeding section and the shallow metering section. The gradual change design balances the conveying volume and the shearing and plasticizing effect.

4. The splitter screw is characterized by a splitter section in the middle of the screw, which is suitable for plastics with poor fluidity, such as polyvinyl chloride (PVC), polystyrene (PS), etc. The design of the shunt section can increase the residence time of the plastic in the screw, thereby improving the plasticizing effect. The barrier screw has a barrier section at the head of the screw, which is suitable for plastics that require high shear plasticization, such as nylon (PA), polycarbonate (PC), etc.
