1. Hardness and Heat Treatment Status Inspection Regular hardness measurements are performed on the barrel surface using a hardness tester. A hardness drop exceeding the design threshold is considered...

Heat dissipation design requirements for a Single Screw Barrel during high-temperature, high-pressure extrusion: 1. Selection of High-Efficiency Heat-Conducting Materials High-thermal-conductivity all...

1. Functional Differences: The Screw Barrel in an injection molding machine is primarily responsible for forcing the melt into the mold and maintaining a seal under high pressure for rapid molding; wh...

1. Matching Abrasion Resistance to Plastic Viscosity: Different plastics have significantly different viscosities and abrasive properties. High-viscosity polycarbonate (PC) or glass fiber reinforced m...

Daily Maintenance Points 1. Clean the unit surfaceAfter each shift, promptly clean the dust and residue from the Parallel Twin Screw Barrel's outer casing, hopper, and conveyor inlet to prevent buildu...

1. Requirement communication and technical solutionThe customer provides process parameters such as rubber type, production capacity, and temperature range. The manufacturer formulates a technical sol...

1. High-precision machining and wear-resistant materialsAdvanced CNC machining centers and precision measurement technologies are used to ensure that the inner wall of the barrel is smooth and defect-...

Temperature Control Methods for Single Screw Extruders 1. Thermocouple + Temperature Controller: Thermocouples measure temperature, and a digital temperature controller (PID) adjusts the heater for pr...

Ten Common Faults of Single Screw Extruders 1. The main motor fails to start or stops momentarily: This is often caused by a power outage, insufficient preheating time, or heater failure, resulting in...

The Impact of a Bimetallic Screw's Thermal Conductivity on Product Quality 1. Improved Plasticizing Uniformity By creating radial convection within the screw channel, a bimetallic screw rapidly transf...

Necessity of Heating1. Achieve Rubber PlasticizationBy heating the barrel wall, the rubber rapidly softens and melts under the screw's action, forming a uniform plasticized rubber compound.2. Ensure T...
