How is precision plastic mold made?
The manufacturing process of precision plastic mold is a complex and fine project, involving many links and key technologies. Below I will describe in detail the manufacturing process of precision plastic molds:
1. Design phase
In the mold design stage, mold engineers need to choose the right mold materials, structural forms and manufacturing processes according to product needs and production conditions. This stage needs to take into account the accuracy, stability, production efficiency and other factors of the mold, but also consider the manufacturing cost and the convenience of maintenance.
2. Preparatory stage
In the preparatory stage, the materials and equipment required for mold manufacturing need to be prepared, and these materials and equipment are inspected and calibrated. This includes the selection and heat treatment of die materials, the accuracy calibration of machine tools and processing equipment, and the accuracy verification of measuring equipment.
3, cavity processing stage
In the cavity processing stage, according to the mold design drawing, the use of CNC machine tools and other high-precision processing equipment to process the mold. This stage requires precise control of parameters such as mold size, shape and surface finish to meet downstream customers’ strict requirements for product consistency and accuracy. For complex cavities, special machining methods such as EDM and laser machining may be required.
4. Assembly stage
In the assembly stage, the mold parts that have been processed are assembled and debugged. At this stage, it is necessary to ensure the assembly accuracy and stability of the mold, and carry out preliminary debugging and inspection of the mold. For high-precision molds, techniques such as optical measurement and error compensation may also be required.
5. Detection stage
In the testing stage, the accuracy and quality of the molds that have been manufactured are tested. This stage requires the use of professional measuring equipment and technology, such as coordinate measuring instrument, optical microscope, etc., to detect the accuracy and stability of the mold. For high-precision molds, surface roughness, hardness and other parameters may also need to be tested.
6, maintenance and maintenance stage
In the maintenance and maintenance stage, the mold needs to be regularly maintained and maintained to ensure the accuracy and stability of the mold. This includes lubrication, cleaning, rust prevention, and repair and replacement of defective molds.
In summary, the manufacturing process of precision plastic mold is a complex and fine project, involving a number of links and key technologies. The manufacturing process needs to take into account the accuracy, stability, production efficiency and other factors of the mold, but also consider the manufacturing cost and the convenience of maintenance.
