Etapa 01
Desenvolvimento
do Ferramental
Criamos os moldes internamente, garantindo alta qualidade e um excelente custo-benefício, fundamentais para a precisão do processo MIM.
Etapa 02
Moldagem por Injeção de Metal
Misturamos pós metálicos finos com aglutinantes e os injetamos no molde sob alta pressão e temperatura. O resultado são “peças verdes”, que permitem ajustes precisos na próxima etapa.
Etapa 03
Extração de Ligantes
Removemos os aglutinantes poliméricos com solventes, preparando as peças para o processo de sinterização.
Etapa 04
Sinterização
Por meio de difusão, as partículas metálicas se densificam, eliminando poros e encolhendo as peças para suas dimensões finais com alta precisão e acabamento superior.
Etapa 05
Operações Secundárias
Finalizamos peças conforme a necessidade com processos como fresamento, rosqueamento, tratamento térmico e revestimentos especiais.
The components must meet certain size and weight limitations to ensure an economic production and a competitive process.
Our engineering team is specialized in evaluating each component and studying ways to optimize the part to make the process economically feasible for our customers.
Stage 01
Tooling Development
We create the molds in-house, ensuring high quality and excellent cost-effectiveness, which are fundamental for the precision of the MIM process.
Stage 02
Metal Injection Molding
We mix fine metal powders with binders and inject them into the mold under high pressure and temperature. The result is “green parts,” which allow for precise adjustments in the next stage.
Stage 03
Binder Extraction
We remove the polymeric binders with solvents, preparing the parts for the sintering process.
Stage 04
Sintering
Through diffusion, the metal particles densify, eliminating pores and shrinking the parts to their final dimensions with high precision and superior finish.
Stage 05
Secondary Operations
We finish parts as needed with processes such as milling, threading, heat treatment, and special coatings.
The main materials used in the MIM process are ferrous materials, such as carbon steels, stainless steels, tool steels, and steels for magnetic applications, among others. Additionally, copper, nickel, cobalt, and titanium-based alloys can also be used.
The main advantages of MIM technology are high shape complexity, dimensional precision, excellent surface finish, and competitive cost for large production batches. Additionally, it is a net shape process, eliminating the need for subsequent machining in most applications
The main consumer markets for components produced by MIM technology include machinery, tools, medical, dental, electronics, automotive, and agribusiness, among others.
There is no ideal size for an MIM component; however, parts weighing less than 30 grams are more common within the technology. Nevertheless, Mipatech’s technology can produce components up to 800 grams.
For high-volume production of small and complex parts, MIM can be more economical than machining and casting.
It reduces material waste and can reduce assembly steps.
MIM has an excellent cost-benefit ratio where the objective is the production of large series of parts, high complexity, and great dimensional precision. It is more advantageous than traditional metalworking production processes, eliminating machining and high raw material waste. Additionally, it is a green process, meaning the amount of scrap and waste is virtually null.
To be economically viable, MIM is recommended for medium to high-volume productions, as there is an initial mold cost, but the cost per piece significantly decreases in larger productions.
High geometric complexity and production volume justify the manufacturing of an injection mold.
While MIM is for metals, CIM is applied to ceramic materials.
Both share similarities in the process, but CIM is chosen when ceramic properties are preferred, such as resistance to extreme heat.
MIM technology is applied to the production of metallic components, while CIM produces ceramic components. However, both use the same production process; what changes is the material to be produced, metal or ceramic. While in metals the objective is mechanical resistance, in ceramics the focus is high wear resistance, thermal and electrical insulation, or high hardness.
MIM produces parts with excellent surface finish, but additional treatments like polishing or coating can be applied to achieve more refined surfaces as needed.
Surface roughness is one of the strengths of MIM technology, as the process can deliver low roughness, improving surface finish. Additionally, MIM allows for the introduction of surface treatments such as painting, chrome, or nickel plating, among others.
