Revolutionizing Hinge Production with Metal Injection Molding

Hinges may seem like a small and insignificant part of a larger product, but they play a crucial role in ensuring that everything functions properly. Historically, hinges have been made through traditional manufacturing methods such as machining or casting. However, in recent years, metal injection molding (MIM) has emerged as a viable alternative for producing high-quality hinges at a more efficient cost.

MIM involves combining metallic powders with a polymer binder to create a feedstock that can be easily molded into intricate shapes. The resulting green part is then sintered at high temperatures to create a final product with excellent mechanical properties. The ability to mold complex shapes and achieve near-net shape production with MIM makes it an excellent choice for producing hinges.

MIM hinges offer a number of advantages over traditional hinge manufacturing methods. For one, they are able to achieve tighter tolerances and more intricate shapes that would be difficult or impossible to produce through machining or casting. This makes them a great choice for applications that require a high degree of precision, such as in the medical industry or aerospace industry.

In addition, MIM hinges are more cost-effective to produce at scale than traditional hinges. Because MIM can produce near-net shape parts with minimal waste material, it reduces material waste and production time. This translates into lower production costs per part, which makes MIM hinges an attractive and viable solution for mass production.

Despite all of these benefits, there are still challenges to overcome in order to fully realize the potential of MIM hinges. For example, optimizing the sintering process to achieve the desired mechanical properties can be difficult and costly. Additionally, MIM hinges still have some limitations in terms of their size and material selection compared to traditional hinges.

However, as technology continues to advance, it's likely that MIM hinges will become more prevalent in a variety of industries. Their ability to produce precise, complex shapes at a lower cost makes them an attractive manufacturing method for many different applications. By utilizing MIM hinges, manufacturers can reduce production costs and improve the overall performance of their products.

Our rapid injection molding Application

Sigma Technik Limited's rapid injection molding service injects molten plastic materials into molds using injection molding machines and molds, and cools and solidifies them over a certain period of time, ultimately forming the required plastic parts. This manufacturing process is usually suitable for producing small and medium-sized plastic parts, which can obtain high-quality and precise parts in a short period of time.

Plastic Injection Molding

Injection molding is a common manufacturing process to produce low volume to large volumes of parts typically made out of plastic. The process involves injecting molten material into a mold and letting it cool to a solid-state.

Liquid Silicone Rubber Molding

Liquid Silicone Rubber is known as LSR, which is a process used to produce parts made from silicone rubber, widely used create products such as medical devices, automotive parts, baby care products, and many others.

2K Injection molding

2K injection molding is a manufacturing process in which two different types of plastic materials are molded together in a single operation to create a single homogeneous component. This process allows for efficient and cost-effective production of high-quality parts that can perform unique functions.

Overmolding and Insert Molding

Overmolding / Insert molding combines two or more materials into a single part, one of the material is usually soft and flexible, or metal. The purpose of overmolding/insert molding is to add functionality, improve grip, provide protection, or enhance aesthetics.

Rapid Injection Molding FAQs

Burrs appear on the surface of the product, which affects its aesthetics and safety. The solution can be to adjust the parameters of the injection molding machine, such as temperature, pressure, speed, etc., or to perform post-processing, such as polishing, sandblasting, etc.

The warping deformation of the product is usually caused by unstable parameters such as temperature and pressure of the injection molding machine, or improper mold design. The solution can be to adjust parameters such as temperature and pressure, or to redesign the mold.

The occurrence of bubbles inside the product may be due to the high temperature of the injection molding machine and the high moisture content of the material. The solution can be to reduce the temperature of the injection molding machine, adjust the water content of the material, increase the pressure of the injection molding machine, etc.

The product size deviation is too large, which may be caused by material thermal expansion, mold deformation and other reasons. The solution can be to adjust parameters and optimize mold design based on material characteristics.
