What are the advantages of injection molding (MIM) components
Injection molding (MIM) parts have many advantages, mainly reflected in the following aspects:
1. complex shape manufacturing capability: MIM can produce extremely complex shapes and structures, which is difficult to achieve by traditional processing methods. It can produce parts with features such as details, thin walls, deep holes, internal threads, etc., such as small complex gears, jewelry wi
Injection molding (MIM) parts have many advantages, mainly reflected in the following aspects:
1. complex shape manufacturing capability: MIM can produce extremely complex shapes and structures, which is difficult to achieve by traditional processing methods. It can produce parts with features such as details, thin walls, deep holes, internal threads, etc., such as small complex gears, jewelry with patterns, etc., which can meet the design requirements of various high-precision and complex shapes.
2. high accuracy and dimensional stability: this process can achieve high dimensional accuracy, and the general tolerance can be controlled between ± 0.1% and ± 0.5%, reducing the demand for subsequent processing and improving production efficiency. At the same time, the parts have good dimensional stability after forming, and can maintain the correct size and shape of the design. It is suitable for applications requiring strict dimensional accuracy, such as parts manufacturing in aerospace, medical devices and other fields.
3. wide selection of materials: MIM can use a variety of materials for component manufacturing, including various metals, alloys and ceramics. Common metal materials, such as stainless steel, titanium alloy, tungsten alloy, etc., can be made into high-performance components through MIM process to meet the requirements of material performance in different application scenarios, such as high strength, high hardness, corrosion resistance, etc.
4. good surface quality: the surface quality of MIM components is usually high, and the surface roughness can reach Ra0.8- Ra1.6 μ m, which can meet the requirements of many applications without additional surface treatment. The smooth surface not only helps to improve the appearance of parts, but also reduces friction and wear, and improves the performance and service life of parts.
5. high efficiency of batch production: injection molding is an efficient batch production process. Once the mold design and manufacture are completed, a large number of identical parts can be produced quickly and continuously, with high production efficiency and relatively low cost. Moreover, with the increase of production batch, the unit cost will be further reduced, which is suitable for large-scale industrial production.
6. near net shape forming: MIM process can realize near net shape forming, that is, the parts are close to the shape and size of the product after forming, and the material utilization rate is high, generally up to more than 90%. Compared with the traditional cutting method, it greatly reduces the waste of materials, reduces the production cost, and reduces the impact on the environment.
