From automotive systems and industrial valves to bathroom hardware and electronic connectors, metal springs play a critical role in modern manufacturing. These precision-engineered components control force, absorb shock, maintain tension, and improve mechanical reliability across thousands of applications. For OEM buyers and industrial engineers, understanding how metal springs are manufactured helps improve sourcing decisions, product […]
Electrical systems in automotive, industrial, energy, and electronic equipment are becoming more compact, high-powered, and application-specific. As a result, standard off-the-shelf connectors are not always enough to meet modern engineering demands. In many OEM and industrial projects, custom terminal and connector design becomes the most effective solution for improving conductivity, reliability, assembly efficiency, and long-term […]

Metal stamping is one of the most efficient manufacturing methods for producing complex metal components in large volumes with consistent quality. For engineers, procurement managers, and product developers, understanding the […]
In the world of manufacturing, choosing the right casting method can make or break your production process. Two popular casting techniques—die casting and sand casting—are commonly used to produce metal parts, but each has its own strengths and limitations. Whether you’re working on high-precision parts for the automotive industry or need to produce large-scale, durable […]
Partnering with the right deep-drawn stamping supplier is a critical decision for any OEM that needs precision custom metal stamping parts. At Thesun Industry, we see the same factors separate reliable partners from risky ones: engineering capability, tooling and pressroom capacity, robust quality systems, and a customer-focused supply chain. Below is a practical, B2B-focused guide […]
At Thesun Industry, we manufacture precision components every day and support OEMs and suppliers with turnkey solutions. Custom machined parts are the backbone of engineered products—from aerospace actuators and medical devices to industrial tooling and consumer hardware.

At Thesun Industry, a precision manufacturer and factory offering one-stop service and tailored custom service solutions, micro machining is a core capability we use to turn demanding designs into high-quality, production-ready components. This guide explains what micro machining is, how it evolved, which processes work best, and how you choose the right equipment and quality […]
Insert molding — also called insert overmolding or metal-to-plastic molding — fuses discrete components (inserts) into molded plastic in a single automated cycle. It’s a powerful approach for producing robust, assembly-free parts that combine the strength of machined inserts or stamped metals with the geometry and sealing of molded polymers. At Thesun Industry we run […]
