Key Characteristics of Injection Molds
Each type of mold has its own features, and injection molds are among those with numerous common characteristics. The external and internal shapes of plastic parts are directly formed by cavities and cores, making the machining of these complex three-dimensional surfaces quite challenging, especially for the inner surfaces of blind holes within cavities. Traditional machining methods not only require highly skilled workers and multiple processes but also result in long processing cycles.
1. High precision and surface quality requirements, along with the need for long service life.
Currently, the dimensional accuracy requirements for general plastic parts are IT6-7, with surface roughness Ra0.2-0.1 μm. Correspondingly, injection molds must achieve dimensional accuracy of IT5-6 and surface roughness below Ra0.1 μm. The laser recording surface of optical discs requires a mirror-like finish of 0.02-0.01 μm, demanding mold surface roughness below 0.01 μm. Long-lasting injection molds are essential for improving efficiency and reducing costs. Currently, the service life of injection molds is generally required to exceed 1 million cycles. Injection molds should employ rigid mold frames, increase template thickness, and add support pillars or conical elements to prevent deformation under pressure, which can sometimes reach 100 MPa. The ejection mechanism is a critical factor affecting product deformation and dimensional accuracy, so optimal ejection points must be selected to ensure uniform demolding. High-precision injection molds often use insert or fully insert structures, significantly raising the machining accuracy and interchangeability requirements of mold components.
2. Long process flow and tight manufacturing timelines.
Most injection-molded parts are complete products that need to integrate with other components, often awaiting market launch. Due to high demands on shape or dimensional accuracy and varying resin material properties, repeated testing and modifications are necessary after manufacturing, making development and delivery timelines extremely tight.
3. Remote design and manufacturing.
Mold manufacturing is not the end goal; product design is proposed by the user. Manufacturers design and produce based on user requirements, and in most cases, the injection molding production of the product occurs at another facility. This results in product design, mold design and manufacturing, and product production being carried out in different locations.
4. Specialized division of labor and dynamic collaboration.
Production batches are small, typically involving single-unit production. However, numerous standard parts are required, from templates to ejector pins, which cannot be produced by a single manufacturer. Moreover, the manufacturing process is complex, with highly uneven usage of conventional and CNC equipment.
