The low-altitude economy is moving from concept to mass production — and precision investment casting plus CNC machining is the least visible yet most indispensable link in this aviation revolution. In October 2026, the low-altitude economy sector delivered a series of concrete developments. Volant signed a purchase agreement with Sichuan Airlines Low-Altitude for 50 VE25-100 passenger eVTOLs, 20 of which are confirmed orders. Aerofugia's AE200 full-scale prototype debuted at the Low-Altitude Economy Industry Development Conference and is in the final sprint toward airworthiness certification, having accumulated over a thousand orders. Meanwhile, the Central Committee of the Communist Party and the State Council explicitly stated in their "Opinions on Developing New Quality Productive Forces" that they will "promote the healthy and orderly development of the low-altitude economy on the premise of ensuring safety."

Dongguan SX Technology Co., Ltd provides one-stop CNC machining solutions for difficult-to-cut materials to customers. Against the backdrop of global manufacturing upgrading, components in fields such as aerospace, marine, ocean, medical, and high-end automation equipment are increasingly turning to high-performance engineering materials. Advanced materials such as titanium alloys (Gr5-TC4, etc.), 7075 aviation aluminum, 316L stainless steel, PEEK, and Grivory have become the preferred choice for high-end product design, thanks to their excellent strength-to-weight ratio, corrosion resistance, high-temperature resistance, and biocompatibility. However, behind the "high value" of these materials lies an extremely high processing threshold —most general-purpose CNC machining factories are often overwhelmed when faced with them, resulting in unstable quality (especially in CNC machining of 316L stainless steel and Gr5 titanium alloy), which frequently causes procurement teams to encounter obstacles when seeking stable, qualified suppliers of high-performance materials.

With the current explosion in AI computing power, liquid cooling has become the standard thermal management solution for high-density data centers, high-power power electronics, energy storage, and new energy equipment. Today, with single-GPU power consumption exceeding one kilowatt and rack-level heat density continuing to rise, air cooling can no longer effectively control chip temperature rise. Liquid cooling, with its ultra-high heat exchange efficiency and lower PUE, has become the core direction for upgrading global computing infrastructure. Whether a liquid cooling system can operate stably over the long term depends primarily on the machining precision and sealing reliability of its various metal thermal components—and precision CNC machining is precisely the core enabler of liquid cooling hardware production. As a manufacturer specializing in precision CNC machining, we leverage our turning, milling, and turn-mill capabilities to provide customized precision liquid cooling thermal management components to customers worldwide.

In 2026, the global supply chain for precision investment cast metal components continues to evolve, with procurement markets placing ever-increasing demands on quality, delivery efficiency, and service integrity. Traditional standalone investment casting models—fragmented across multiple processes, suppliers, and quality control gaps—are struggling to meet the customized requirements of high-end sectors such as aerospace, new energy, pump/valve hydraulics, marine engineering, and medical devices. Against this industry backdrop, the integrated full-process solution combining investment casting, precision CNC machining, and surface finishing has emerged as a core competitive advantage for Chinese precision casting companies going global, earning widespread recognition and preference from overseas customers thanks to its fully traceable, high-quality, cost-effective, and fast-delivery benefits.

In high-end manufacturing fields such as robotics, aerospace, medical devices, and premium automotive parts, the demand for non-standard, complex structural components and small-batch, multi-variety custom parts has long become the mainstream in the CNC machining service industry. However, traditional CNC machining still struggles with persistent pain points: time-consuming and error-prone programming for complex workpieces, heavy reliance on manual experience, deformation and chatter marks when machining thin-walled or high-hardness materials, inconsistent precision across batches, and long lead times for prototyping. These issues severely hinder product development and project execution for manufacturers.

Stainless steel precision investment casting parts are metal components produced through a specialized casting process. The core principle involves using a consumable pattern (e.g., a wax pattern) to form a cavity within a metal mold, followed by pouring molten metal. After cooling and solidification, a precision casting component with a shape identical to that of the pattern is obtained.

In the production of investment casting, the process is complex and the working environment is harsh, making it particularly suitable for the introduction of industrial robots to enhance automation, ensure quality consistency, and improve occupational safety. In addition to replacing human workers in high-temperature, polluted, and hazardous environments, industrial robots can also increase work efficiency, improve product precision and quality, reduce costs, minimize waste, and enable flexible, sustained, high-speed production processes. By integrating precision casting processes, foundry equipment, and industrial robots, companies can continuously develop project applications in the casting field. Industrial robots can also help address social challenges faced by enterprises in their future development, such as "difficulty in recruiting," "difficulty in retaining talent," "environmental pressures," as well as efficiency-cost trade-offs. Next, let’s explore the core applications of industrial robots in the following areas:

In the field of metal parts manufacturing, the choice between CNC machining and investment casting has long been a challenge for engineers. CNC machining is renowned for its exceptional flexibility and precision, while investment casting holds a significant position in mass production due to its cost advantages. In simple terms, for metal parts that require high precision but are needed in small quantities (e.g., prototypes), precision CNC machining is the preferred option. For batch production—whether small or large—parts with complex geometries and less stringent precision requirements may be suitable for investment casting, or a combination of investment casting and CNC machining. Next, let's explore the applicable scenarios for each process through the following points and reveal the direction of technological innovation in investment casting.

With the development of the AI era, what impact will AI truly have on our CNC machining industry? In fact, AI is part of nearly every business conversation these days. Regardless of the industry, business owners and decision-makers are considering how to leverage AI technology to improve profitability, and precision CNC machining is no exception. The advancement of AI in CNC machining is one of many innovations, but it may be the most significant.

The impact of rising oil prices on the investment casting and CNC machining industries is most directly reflected in higher energy costs, increased raw material prices, and rising logistics expenses. This leads to an overall increase in manufacturing costs across these industries. Currently, a high-oil-price environment has taken shape globally and shows signs of persistence. From an international perspective, since October 2025, escalating geopolitical conflicts in the Middle East, combined with the Red Sea shipping crisis and transportation risks in the Strait of Hormuz, have continuously tightened global crude supply expectations, driving oil prices up sharply. For us in the manufacturing industry, overall costs are constantly rising. This is especially impactful for the export sector, as increasing logistics costs lead to a significant rise in the final cost of products delivered to customers. Below, we will discuss the impact of oil prices on our operations from the perspectives of raw materials, energy, logistics, and downstream demand changes.
