Precision injection molding is a process that requires high technique and the use of precision molds and precision machines. The process of precision mould is different from normal injection mold but it still belongs to injection mold. It requires strict tolerance of ±0.01 mm and it will be processed by high precision machine and technique. It has strict requirements for venting, material flowing, and cooling which enable molding parameters to be stable. This process is called scientific molding. We will suggest making a prototype mold first for testing before we make a precision mould. For more details, please don't hesitate to contact us today!

The Components of Precision Moulds 

The success of precision mould includes the following:

  • Precise control of the mold cavity size

  • Precision of parting surface

  • Exact solution of material

  • Strict requirement for a tolerance

  • Venting design

  • Material flowing

  • Cooling system

  • Choosing of steel material

  • Overall excellent tooling design

Applications of Precision Mould

As mentioned earlier, precision mould is used for the development of various products. But this technology has really revolutionized the development of lenses in various applications because it allows OEM to manufacture cheaper and stronger glass-free lenses. Glass lenses are very delicate, difficult to manufacture, and expensive, but plastic optical lenses have completely changed the optical industry. Precision molding is used for the development and mass production of precision spherical, diffraction, free-form surface, aspheric, and other types of lenses. It is a high-quality product with a perfect optical surface finish.
