Advantages
Our gear molds and gear injection molded parts have three core advantages:
Accuracy guaranteed: The mold adopts high-precision CNC and electrical discharge machining, with tooth profile tolerance controlled within ± 0.01mm, and high dimensional consistency in mass production.
High production efficiency and low unit cost:The injection cycle is 10 – 60 seconds. The first mock examination is designed with multiple cavities. The cost of a single piece in a large batch is far lower than that of machined gears, and the material utilization rate is close to 100%.
Flexible materials and structures:Supporting engineering plastics such as POM, PA+fiberglass, PEEK, etc., it can be used for insert injection molding (metal shaft/skeleton integrated molding), and complex tooth shapes can be completed in one time.
FAQ
Q:How much tooth accuracy of gear parts can be achieved ?
A:Tooth profile tolerance ± +/-0.002mm, tooth profile tolerance ± 0.015mm, coaxiality ≤ 0.02mm
Q:What gear tooth profiles can we make?
A:Straight teeth , helical teeth gear , herringbone teeth gear , worm gear
Q:What are the commonly used gear materials?
A:POM, PA, PEEK etc.
Different materials have significant differences in strength, wear resistance, temperature resistance, and moisture absorption. We will provide suitable materials according to your needs
Q:How to control the deformation and shrinkage of gears?
A:Cooling shrinkage of plastic gears can cause distortion of tooth profile and loss of roundness in the inner hole. We will use mold flow analysis to optimize the gate and cold cutting, adjust the holding pressure parameters, and whether there will be subsequent shaping or precision machining.
