The cost and quality of a manufactured part depends on the accuracy and speed of its production. Industrial manufacturing uses plastic injection molding to reduce material costs while maintaining high levels of production capacity. The key concept is accuracy, especially for industries that require complex or complex parts. To ensure precision, high tolerances, quality and long-term durability, manufacturers must use impeccable machine tools. You can create high-quality molds using CNC machining, a process that removes metal accurately.
Mastering the mold design process is critical. The higher the required precision and mass production, the more complex the tooling. Manufacturers use computer numerical control to create this high precision, replacing manually operated machines, vertical mills and lathes with centralized automation systems. CNC machines convert CAD models into mass-produced parts that differ by as little as 0.0001. They operate through advanced manufacturing techniques, using a variety of cutting tools to remove material from solid blocks to achieve the intended design.
There are three basic types of CNC machining: Milling mounts the part on the bed and uses a rotary cutting tool to remove material to create a product in a variety of shapes. Turning mounts the part on a rotating chuck and uses a stationary cutting tool to remove material, resulting in an axially symmetrical end product. EDM uses controlled discharge to achieve the desired shape. CNC machining uses many common materials including: aluminum, stainless steel, brass, other types of metals.
The cost of manufacturing high-quality stainless steel molds is often the most significant financial investment in the plastic injection molding process. Since millions of plastic parts will eventually be made from these molds, it is important to ensure mold reliability and accuracy ahead of time to avoid inaccuracies and failures over time.
Using CNC machining to make molds has many advantages that benefit the end user: CNC machining produces parts in just a few steps, which increases efficiency; the process is more precise than manual machining and can be repeated over and over again in the same way; Offers the ability to produce complex shapes with high precision; CNC machining operates using advanced CAD software to produce outputs and multiple functions that cannot be reproduced manually; a fully automatic system means no safety risks for operators.
