As a high-precision and high-quality manufacturing method, stainless steel investment casting is widely used across various industrial sectors. However, its cost is relatively higher compared to traditional casting processes. The cost of stainless steel castings is influenced by multiple factors, including raw material costs, process complexity (casting costs), post-casting processing expenses, market supply and demand, and other related expenditures. In the following sections, we will analyze the cost of stainless steel castings from several perspectives, hoping to provide some useful insights.

We are pleased to announce that, to better serve our international clients and streamline the management of domestic and overseas operations, the company will relocate to a new facility starting October 2025. Additionally, we will integrate our export business with the former Shenzhen SCZY Technology Co., Ltd (hereinafter referred to as "SCZY"). Following this transition, SCZY will focus entirely on serving domestic clients and manufacturing products for the local market, while Dongguan SX Technology Co., Ltd (hereinafter referred to as "SX") will dedicate all resources to international customer service, overseas product manufacturing, and after-sales support.

In today's manufacturing industry, CNC machining technology plays a pivotal role and is indispensable across almost all sectors. Among its various processes, CNC milling and CNC turning are two of the most common and core machining methods. Both utilize programmed control of machine tool movements to produce parts with high precision and efficiency. However, they differ significantly in their machining principles, applications, and the types of parts they can produce. Below, we explore their differences.

Non-standard CNC precision machining custom, as the name implies, goes beyond traditional single-part manufacturing by providing comprehensive CNC machining services tailored to clients' specific requirements - from material selection (sometimes starting with design) through production processes to final product delivery. This service model breaks through the limitations of conventional manufacturing, placing greater emphasis on client communication and collaboration to meet personalized and diversified needs. Amidst the dual waves of industrialization and digitalization, the manufacturing sector is undergoing unprecedented transformation. Traditional CNC parts production is gradually being replaced by more efficient and flexible methods, with custom precision CNC machining gaining widespread adoption due to its unique advantages. Below we explore the distinctive characteristics of custom precision CNC machining services:

In recent years, China's CNC precision machining industry has continued to grow, while manufacturing in Southeast Asia has also developed rapidly. With some foreign companies relocating production lines from China to Southeast Asian countries, can Southeast Asia truly replace China as the "world's factory"? In reality, this remains quite difficult. After decades of development, China's CNC machining industry has established a complete industrial ecosystem, with end-to-end production capabilities—from raw materials to high-end components. This well-integrated supply chain allows China to respond swiftly to order demands, an advantage that Southeast Asian countries cannot easily match in the short term. Below, we analyze the differences between China and Southeast Asia in custom CNC machining from several key perspectives:

In precision CNC machining, where each component ultimately serves as part of a final assembly, it is essential to thoroughly understand the assembly methodology, functional purpose, and operational requirements of the end product before commencing machining operations. This foundational understanding allows for proper attention to critical tolerances and manufacturing processes, ensuring components are produced with assembly compatibility and optimal performance in mind. A case in point is our recent OEM project involving precision CNC machining parts and assembly, where the client provided comprehensive specifications regarding product application and functionality but limited tolerance requirements - necessitating our team to establish appropriate tolerance controls based on the component's actual operational demands. We will now proceed to discuss the following key aspects: auxiliary component selection, machining processes, cleaning and degreasing procedures, surface coating applications, and product quality inspection protocols.

Some custom investment castings are prone to deformation during production due to factors such as wax pattern distortion, structural design issues, mold shell warping after pouring, improper handling by workers during sand cleaning and shell shaking, heat treatment effects, or welding distortions during wax pattern assembly. These issues can lead to dimensional deviations or shape alterations, necessitating subsequent corrective measures. Correction is typically performed by applying external force, either at room temperature or elevated temperatures, and common methods include free correction, die correction, cold correction, and hot correction.

For investment casting parts, achieving true product excellence requires not only meticulous control during the casting process itself but also strict post-casting procedures to ensure high-quality output. This is especially critical for thin-walled parts, which often require supplementary processes to refine the castings and meet functional specifications. In OEM investment casting, many products demand tailored post-processing based on their actual application to guarantee compliance with performance requirements. Below, I will analyze several common auxiliary processes based on our recent production of specific components.

Titanium alloy bolts are fasteners made from titanium alloy materials, valued for their low density, lightweight properties, high strength, and corrosion resistance, making them ideal for industrial applications in extreme environments. They are widely used in industries such as electroplating, chemical processing, aerospace, and marine aquaculture, often requiring custom machining based on client specifications, though they come at a relatively high cost. So, how can we determine whether a custom titanium bolt is genuinely made of titanium alloy? The following methods can be used for verification:

CNC titanium machining is widely used in the manufacturing of titanium alloy components due to their high strength, corrosion resistance, and lightweight properties, making them essential in various industries, including specialized applications. However, titanium alloys are notoriously difficult to machine compared to materials like carbon steel or stainless steel because of their low thermal conductivity, high chemical reactivity, and low elastic modulus. These characteristics often lead to challenges such as low machining efficiency, rapid tool wear, and poor surface quality. To effectively enhance both efficiency and quality in titanium alloy machining, a multi-faceted approach is required, which can be analyzed from the following three key aspects:
