New High-Performance Taps for Precision Threading of Hard-to-Cut Aerospace Alloys

In the mold industry, injection molds have gained widespread application. As a processing technique for mass production of components, injection molding is predominantly adopted across industrial sectors. What are the various application fields of injection molds? Let us take a closer look in the following sections.

Application Fields of Injection Molds

Injection molds are critical process equipment for manufacturing diverse industrial products. Driven by the rapid growth of the plastics industry and the extensive adoption of plastic parts in aviation, aerospace, electronics, machinery, shipbuilding, automotive and other industrial segments, performance requirements for molds have become increasingly rigorous. Conventional mold design approaches can no longer satisfy modern manufacturing demands. Compared with traditional mold design, Computer Aided Engineering (CAE) technology delivers remarkable advantages in lifting productivity, guaranteeing product quality, cutting manufacturing costs and lowering labor intensity.

A full range of numerical control (NC) machining technologies are utilized in injection mold manufacturing, among which NC milling machines and machining centers are the most commonly deployed. NC wire electrical discharge machining (WEDM) and NC electrical discharge machining (EDM) are also widely applied in mold NC processing. Wire EDM is mainly used for machining molds with straight vertical walls, including male and female stamping dies, inserts and sliders of injection molds, as well as electrodes for EDM operations. EDM serves as the primary processing method for ultra-hard mold components that cannot be machined by conventional cutting. It is also applied to machine sharp corners, deep cavities and narrow grooves on mold cavities. NC lathes are primarily used to produce shaft-type standard mold components and rotary mold cavities or cores, such as injection molds for bottles and basins, as well as forging dies for shaft and disk workpieces. NC drilling machines help boost machining accuracy and shorten production cycles during mold fabrication.

Molds boast an extremely broad scope of applications. Forming processes for nearly all structural parts in modern manufacturing rely on molds. Therefore, the mold industry constitutes an essential part of national high-tech industries and represents vital, valuable technical resources.
