일반적으로 금속분말 사출성형법(MIM: Metal Injection Molding Process)은 플라스틱 산업에서 오랫동안 배양된 사출성형(Injection Molding) 기술과 분말야금산업에서 발달한 금속분말의 소결 기술 양쪽의 이점을 융합시킨 공정이라고 할 수 있으며, 특히 3차원적인 형상을 가지며, 초경공구 등을 대량으로 제조할 수 있는 기술로서, 금속, 초경, 세라믹 등 분말 소재를 사용하여, 성형 및 소결시켜 제품을 생산하는 기술이다.In general, the metal injection molding process (MIM) is a process that combines the advantages of both injection molding technology, which has been cultivated in the plastic industry for a long time, and sintering technology of metal powder developed in the powder metallurgy industry. In particular, it has a three-dimensional shape, and is a technology that can produce a large amount of carbide tools, such as a technology of producing a product by molding and sintering using a powder material such as metal, carbide, ceramics.
원리적으로는 금속분말과 바인더 혼합물의 사출성형품을 가열하여 탈지, 소결을 통하여 고기능 복잡형상의 작은 부품을 제조하는 방법이다.In principle, it is a method of manufacturing small parts of high functional complexity through degreasing and sintering by heating injection molded articles of metal powder and binder mixture.
이런 금속분말 사출성형기술과 플라스틱 사출성형기술의 가장 큰 차이점은 금속분말 사출성형에서는 사출성형 후, 결합 제를 제거하고, 분말을 고온소결을 통하여 최종 제품을 제조한다는 것이다.The biggest difference between the metal powder injection molding technology and the plastic injection molding technology is that in the metal powder injection molding, after injection molding, the binder is removed and the powder is hot sintered to produce the final product.
여기에 사용되는 금속분말은 특히 융점이 높아 용융성형이 곤란하며, 또한 경도가 높아 절삭가공 등이 곤란한 금속제의 공구 등의 제조에 응용되고 있다.The metal powder used here has a particularly high melting point and is difficult to melt molding, and has a high hardness, and has been applied to the manufacture of metal tools and the like which are difficult to cut and the like.
그러나, 상기한 MIM을 이용하여 생산하는 제품은 금속분말의 사출, 탈지, 소결 공정을 순차적으로 수행하여 만들어진 것으로 표면의 강도는 1GPa 이상의 강도를 갖기 때문에 상기 제품의 후처리로 표면을 가공하며 무늬 또는 모양 등의 패턴을 표면에 처리하기에 매우 어려움이 많으며, 바렐 등 단순한 표면처리 할 수 있을 뿐 외관이 미려한 제품을 생산하니 못하는 문제점이 있으며, 생산 하더라 해도 디자인에 따른 제작 비용이 상승되는 문제점이 있다.However, the product produced by using the MIM is made by sequentially performing the injection, degreasing, and sintering process of the metal powder. Since the surface strength has a strength of 1 GPa or more, the surface is processed by post-treatment and the pattern or It is very difficult to process patterns such as shapes on the surface, there is a problem that can not simply produce a surface with a simple surface treatment, such as barrel, it is not possible to produce a product with a beautiful appearance, and even if produced, the production cost according to the design is increased. .
상기한 문제점을 해결하기 위하여 본 발명은 다양한 무늬 및 모양의 패턴을 갖는 코어를 통해 소결 가공된 완성제품의 표면에 추가적인 가공 없이 미려한 디자인의 패턴을 구현할 수 있고, 이에 따라 가공비용을 절감할 수 있어 미려한 디자인의 패턴을 갖는 완성제품을 저렴하게 보급할 수 있는 고강도금속표면에 패턴 형성 방법을 제공하는데 목적이 있다.In order to solve the above problems, the present invention can implement a beautiful design pattern without additional processing on the surface of the finished product sintered through the core having a variety of patterns and shapes, thereby reducing the processing cost An object of the present invention is to provide a pattern forming method on a high-strength metal surface that can be inexpensively distributed to a finished product having a beautifully designed pattern.
상기한 목적을 달성하기 위하여, 본 발명은 금속분말과 바인더를 혼합하여 공급원료를 생성하는 생성단계와; 안쪽에 설정된 무늬 및 모양의 패턴을 갖는 코어를 포함하는 사출성형기에 상기 공급원료를 공급하여 표면에 패턴이 형성된 성형제품을 성형하는 성형단계와; 소결로를 통해 상기 성형제품을 소결하여 완성제품을 생산하는 소결단계를 포함하는 것을 특징으로 하는 고강도금속표면에 패턴 형성 방법을 제공한다.In order to achieve the above object, the present invention comprises the steps of producing a feedstock by mixing a metal powder and a binder; A molding step of molding the molded article having a pattern formed on a surface thereof by supplying the feedstock to an injection molding machine including a core having a pattern set in a pattern and a shape therein; It provides a pattern forming method on a high-strength metal surface comprising a sintering step of producing a finished product by sintering the molded product through a sintering furnace.
이때, 상기 소결단계 후 완성제품의 패턴을 표면 처리하는 표면처리단계를 더 포함하는 것을 특징으로 한다.At this time, after the sintering step is characterized in that it further comprises a surface treatment step of surface treatment of the pattern of the finished product.
또한, 상기 소결단계 후 상기 성형제품에 비해 상기 완성제품의 수축되는 수축비율을 측정한 데이터를 기초로 보정된 패턴을 갖는 코어를 상기 사출성형기에 교체하여 초기 패턴을 수정함에 따라 완성제품의 패턴을 보정하는 패턴보정단계를 더 포함하는 것을 특징으로 한다.In addition, after the sintering step, the core having a corrected pattern based on the data of measuring the shrinkage shrinkage ratio of the finished product compared to the molded product is replaced with the injection molding machine, thereby modifying the initial pattern. It characterized in that it further comprises a pattern correction step of correcting.
한편, 상기 소결단계 후 다른 패턴을 갖는 완성제품을 생산할 수 있도록 다른 무늬 및 모양의 패턴을 갖는 코어를 상기 사출성형기에 교체하는 패턴변경단계를 더 포함하는 것을 특징으로 한다.On the other hand, it characterized in that it further comprises a pattern changing step of replacing the core having a different pattern and pattern to the injection molding machine to produce a finished product having a different pattern after the sintering step.
