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 thecasting processitself 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:

The term "precision casting" generally excludes sand casting and primarily refers to processes such as investment casting (also known as lost wax casting), ceramic mold casting, permanent mold casting, die casting, lost foam casting, and vacuum casting. Among these casting processes, investment casting and sand casting are the most common and widely used in manufacturing. Although they differ significantly in production methods and product requirements, these two processes are most easily confused. The following two images illustrate their respective processing techniques (for reference only). Today, we can discuss whether to choose investment casting or sand casting based on factors such as cost considerations, precision requirements, and surface finish requirements:

Regarding how to ensure quality in CNC metal machining, today I’ll use a metal product we recently manufactured as a case study for discussion. At first glance, the drawing may seem straightforward, but this part requires multiple processes—CNC turning, grinding, heat treatment, surface finishing, and more. Meeting the client’s specifications and dimensional tolerances at every stage is quite challenging. Below are the drawing and product photos. Based on our hands-on machining experience, we’ll analyze the key aspects in detail:

Although titanium bolt offer advantages such as high strength, lightweight properties, corrosion resistance, and non-magnetic characteristics, whether they can fully replace stainless steel bolt requires a comprehensive discussion based on cost factors, performance characteristics, application scenarios, and manufacturing processes:
