Mold manufacturing process

Product Design, Research and Development
In the early development of new products for customers, we use 3-demensional to complete all layout designs, from product appearance to all details, first use 3D design software, and then conduct strict research and inspection. In the initial stage, all flow plastics, assembly inspection and intervention inspection analysis etc. are carried out with the assistance of CAE software to ensure high resolution and high quality.

CNC Machining Integrated Data

Using advanced CAM software, output accurate design data to provide an effective solution for the machining of all accessories.

  1. mold design
    Use efficient 3D design software (Pro/E) to design molds. When designing, the design data of the mold base, ejector pin, cooling system, and standard parts are input into our database server and can be output quickly. With the help of this system, we can design molds efficiently, accurately and standardizedly.
  2. manufacture
    We have a complete set of automation, high-precision CNC machining equipment. Efficient machining techniques help maintain consistent quality and precision molded parts. (see detailed notes on equipment list). Various processing machinery, connection of computer network, direct transmission of data using CAD/CAM. .
  3. quality assurance
    High-precision three-dimensional coordinate measuring machines allow us to try out products, conduct thorough inspections and tests on drafts, to ensure that every finished product delivered to our customers meets the requirements of measurement.
