Rapid Injection Molding - A Cost-Effective Solution for Your Manufacturing Needs

Injection molding is a popular manufacturing process for producing identical parts in high volume. However, traditional injection molding can be a time-consuming and expensive process, particularly when it comes to designing and producing injection molds. Rapid injection molding has emerged as a viable solution to this problem, providing a cost-effective and efficient alternative that allows manufacturers to produce high-quality parts in just a few days.

What is Rapid Injection Molding?

Rapid injection molding is a process that utilizes advanced technologies to create injection-molded parts quickly and inexpensively. It is the ideal solution for manufacturers that require smaller quantities of parts or need parts produced quickly. The process involves using a pre-existing mold that has been created using 3D printing, cast urethane, or CNC machining. From start to finish, the process takes a little as five days to complete.

Advantages of Rapid Injection Molding

Rapid injection molding offers several advantages over traditional injection molding, including:

Cost-Effective: Traditional injection molding requires a significant investment to create the injection mold. Rapid injection molding uses pre-existing molds, reducing the cost significantly.

Quick Turnaround Time: Traditional injection molding can take weeks or even months to complete. Rapid injection molding can produce parts in as little as five days and has a significantly shorter lead time.

Low Production Volume: Rapid injection molding is ideal for low-volume production runs.

High-Quality Parts: Rapid injection molding uses high-quality materials and the latest technologies to produce parts that meet or exceed industry standards.

Design Flexibility: Rapid injection molding allows manufacturers to make changes quickly and easily to the mold design.

Applications of Rapid Injection Molding

Rapid injection molding can be used in several industries for various applications, including:

Aerospace

Automotive

Consumer Products

Electronics

Medical Devices

In the aerospace industry, rapid injection molding can be used to produce components such as ventilation ducts, air distribution systems, and structural parts. In the automotive industry, it can be used to produce parts such as interior trims, electrical housing, and mechanical parts. For consumer products, it can be used to produce parts such as housing for appliances, remote controls, and toys. In the electronics industry, it can be used for parts such as camera housings, printer components, and computer peripherals. In the medical device industry, it can be used to produce parts such as surgical instruments, drug delivery devices, and implantable devices.

Conclusion

Rapid injection molding is a cost-effective and efficient solution for manufacturers that require smaller quantities of parts or need parts produced quickly. It offers several advantages over traditional injection molding, including lower costs, faster turnaround time, and design flexibility. With its wide range of applications and benefits, rapid injection molding is sure to become an increasingly popular choice for manufacturers looking for a cost-effective and efficient solution for their 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.
