What are the requirements for injection mold design and manufacturing?

The design and manufacturing of injection molds have various requirements to meet. Injection molds are intended for repeated use, often in high-efficiency factories where the cycles are short and the repetition is high. While meeting precision requirements, injection molds also need to achieve long lifespan while considering mold closing process, injection process flow, holding pressure process flow, cooling process flow, mold opening process flow, and product removal process flow. For each step, specific solutions need to be provided in the design and manufacturing of injection molds; otherwise, it may lead to mold scrap.

 

In the field of mold manufacturing, material selection is crucial. Various alloys can be applied in mold manufacturing, such as zinc alloys, stainless steel, copper-based alloys, aluminum alloys, high carbon steel, each requiring different smelting techniques in the production process. It involves forging or casting techniques, followed by precision machining using lathes, such as CNC technology, laser cutting technology, Wire cutting technology, and polishing technology. The higher the precision of the processing technology, the higher the precision of the mold in production, which is no secret in the design and manufacturing of injection molds.

The most challenging part of injection mold design and manufacturing lies in the design phase. Designers need to consider multiple factors such as molding accuracy, material properties, temperature, density, and also focus on the mold’s service life. In addition, detailed consideration is needed on parameters such as plasticizing pressure, injection pressure, molding cycle, holding pressure and time, back pressure, among others, or else the manufactured mold may have defects. If the mold’s lifespan does not meet standards, it will increase manufacturing costs; and if the precision is not up to standard, it may lead to a large number of product defects. Therefore, an excellent design is equivalent to half the success in production.
