  • The working principle of a molding machine is similar to that of a syringe used for injection. It uses the thrust of a screw (or plunger) to inject the melted plastic (i.e. viscous flow) that has already been plasticized into a closed mold cavity, and then solidifies to obtain th...
  • 1.Before starting the machine, check the household appliances and mechanical equipment of the extruder equipment to ensure accuracy before starting production and manufacturing. 2. Preparation before production and manufacturing: Actual operators should wear protective equipme...
  • Cold roll forming refers to the continuous transverse bending of metal sheets or strips, such as coils and strips, through sequentially configured multi pass forming rollers, in order to produce the required specific cross-sectional profiles. So, it is also a plastic process...
  • 1、 Punching process. This is a process that is commonly used on most profiles, and many profiles are perforated. However, integrating the punching process on a rolling forming machine is not complicated, so the punching process is very common. 2、 Cutting or cutting process. On...
  • Straightening heads are often used in rolling forming processes. When there are bending, twisting, ripple, and other situations in the formed product, using straightening heads can effectively correct these problems. Some molding machine manufacturing factories may omit this stra...
  • 1. The overall structural waterproofing and drainage function allows for complete articulation of joints regardless of the shape of the building. The entire roof has no nail holes, allowing for free expansion and contraction of the roof during temperature changes, avoiding temper...
  • The plate leveling machine is suitable for leveling hardware plates after punching, sheet metal parts after laser cutting, flat plates processed by CNC computer gongs, metal stainless steel plates, metal mesh plates, and other products. It is a roller type leveling equipment, and...
  • Cold rolling forming machine is characterized by small Moment of inertia of roll, compact structure, and can be adjusted in a wide range. The cold rolling forming machine is composed of a main transmission device and two driven transmission hydraulic support frames. The main f...

  • 1.When troubleshooting the cylinder of the cold bending forming equipment, first check whether the valve core is stuck or the valve hole is blocked, or whether the piston rod and cylinder are stuck. These faults are generally caused by dirty hydraulic oil. After cleaning the oil ...
  • 1. Regularly inspect the components, 1-2 times a month, and check whether the movable parts such as worm gear, worm gear, bearings, pressure wheels, crankshaft, upper and lower rail guides rotate flexibly and wear. If defects are found, they should be repaired and used in a timel...
  • Increase production: Install a metal roller forming machine in the grinding system, whose high-pressure load is transmitted to the material layer being ground through the diameter of the double rollers. Most of the energy is used for mutual compression between materials, converti...
