Problems solved by technology

[0002] With the development of science and technology, the scope of mold application is becoming more and more extensive. For the manufacture of product molds with multiple varieties, small batches or frequent updates and modifications, such as injection molds, blow molds, and compression molds, it is required to have manufacturing It has the characteristics of short cycle, low manufacturing difficulty and low cost, while the steel mold usually used in the prior art has high manufacturing cost and long cycle, and the cost of nickel-chromium alloy material is relatively low, so it is widely used in the field of manufacturing such molds
However, pure metals cannot meet the requirements such as plasticity, hardness, strength, etc., so alloying elements are usually added to improve their physical and mechanical properties.
