Revolutionizing Injection Molding with 3D Printed Metal Molds: A New Era of Efficiency and Customization

And here's a blog post to go with it:

Injection molding has long been a staple of manufacturing, allowing for the mass-production of complex plastic parts with ease and accuracy. However, traditional injection molding techniques often require the use of costly and time-consuming machining processes to produce mold tooling. This has led to a search for more efficient and cost-effective methods of producing molds.

Enter 3D printing technology. With recent advancements in metal 3D printing, it is now possible to directly produce molds for injection molding without the need for expensive and time-consuming machining processes. This revolutionizes the injection molding process, reducing costs, and streamlining production timelines.

So, how does it work? 3D printed metal molds for injection molding can be created using various metal printing processes, including direct metal laser sintering (DMLS) and binder jetting. These processes involve the layer-by-layer deposition of metal powder or metal to create a mold tooling. This method allows for highly precise and complex mold geometries that could not otherwise be produced with traditional machining methods.

3D printed molds have numerous advantages over traditional machined molds. First and foremost, they are significantly faster to produce. The cost of producing the mold is also lower as there is less need for manual labor, resulting in lower labor costs. In addition, 3D printed molds allow for greater design freedom which can lead to the production of more complex and custom geometries, this is particularly important for industries that require a significant amount of customization for their products. The mold can also be easily modified to make design tweaks, which can lead to further cost savings and improved part quality.

One area where 3D printed mold technology has been particularly effective is in low volume production. This is because traditional machining methods are often cost-prohibitive for low volumes of parts, while 3D printed molds can be produced with minimal investment, making it an ideal choice for small-sized businesses.

In conclusion, 3D printed metal molds for injection molding represent a significant advancement in manufacturing technology. With the ability to produce highly complex molds quickly and at a fraction of traditional manufacturing costs, 3D printing technology has the potential to revolutionize the injection molding industry and improve the production of plastic parts for a variety of industries. Whether it is for low-volume production or high-volume customization, 3D printed metal molds provide a versatile and cost-effective solution for manufacturing needs.

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.
