Customized Accurate POM Nylon Gear Moulding.
The complex to make the precision plastic gear mold and moulding :
high precision requirements : the precision of the gear directly affects its transmission performance and service life. Injection molded gears need to meet strict dimensional tolerances, form and position tolerances and tooth profile accuracy requirements. For example, the module, number of teeth, pressure Angle and other parameters of the gear must be accurate, otherwise it will lead to loud noise, severe vibration and even stuck in the transmission process of the gear
one
. In addition, the shrinkage characteristics of plastics is one of the main factors affecting the accuracy of the gear, the uneven cooling during the injection molding process will also lead to the deformation of the gear, further affecting its accuracy .
constraints on material properties : Choosing the right plastic material is the key to the production of high quality gear injection parts. The ideal gear injection molding material should have high strength, high rigidity, wear resistance, low friction coefficient and good dimensional stability. However, the plastic materials currently on the market are difficult to meet these requirements at the same time. For example, engineering plastics such as polycarbonate (PC) and polyformaldehyde (POM) have relatively poor wear resistance although they have high strength and rigidity; And some plastic materials with good wear resistance, such as ultra-high molecular weight polyethylene (UHMWPE), its rigidity and dimensional stability are often not satisfactory
one.
complex injection molding process : The shape of the gear injection molding parts is usually more complex, which puts forward high requirements on the injection molding process. During the injection molding process, it is necessary to ensure that the plastic melt can evenly fill the mold cavity to avoid defects such as lack of material, bubbles, and welding marks. For parts with complex tooth shapes such as gears, plastic melt is easily affected by flow resistance during the filling process, resulting in uneven filling, which affects the quality of gears
one.
Measures to improve the precision of gear mold :
Optimize the mold design : reasonable design of the position and number of gates to ensure that the plastic melt can fill the mold cavity smoothly, avoid turbulence, thus affecting the forming quality of the gear
one.
control injection molding process : by precisely controlling the temperature, pressure and other process parameters in the injection molding process, reduce the shrinkage and deformation of plastics, and ensure the dimensional accuracy and shape and position tolerance of the gear
one.
The use of high-performance materials : select high-performance plastic materials, such as materials with reinforcement fibers, to improve the strength and rigidity of the gear, while improving its wear resistance
