Modern vehicles rely on thousands of electrical connections to power everything from engine control units to advanced driver-assistance systems. Behind this complexity, electrical terminals and terminal connectors serve as the critical interface that ensures reliable power transmission and signal integrity. For OEMs, Tier 1 suppliers, and procurement teams, selecting the right metal terminals is essential […]
As technology continues to evolve, membrane switches are becoming indispensable in a wide range of industries. Their unique design, exceptional functionality, and reliability make them a key component in many electronic products. In this post, we’ll take a deep dive into membrane switches—exploring their basic principles, types, manufacturing processes, and how they stack up against […]
At Thesun Industry, we work with automotive buyers, aftermarket brands, and industrial customers who need reliable battery connectors that deliver stable power transfer, easy installation, and long-term durability. Choosing the right battery terminal connectors is not just about fit. It is about conductivity, corrosion resistance, installation convenience, and whether the part can support the real […]
So you’ve got a shiny part in your hands. It’s perfectly cut, precisely shaped, and looks like it could survive a small earthquake. But wait! That raw, unfinished surface? It needs a little TLC before it’s truly ready for the real world. And that’s where surface finishes come in. Don’t worry, we’re not talking about […]
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 […]
At Thesun Industry, a precision manufacturer and factory specializing in elastomeric flow-control components, we produce high-performance umbrella check valves (often called mushroom valves) for medical devices, consumer products, and industrial fluid systems. This guide explains why mushroom valves deform, how material choice and design prevent failure, and why Liquid Silicone Rubber (LSR) umbrella valves are […]
Are you evaluating one-way valve options for a medical device, micro-pump, condiment dispenser, or portable consumer product? At Thesun Industry we design and manufacture custom silicone duckbill valves using precision liquid silicone rubber injection molding (LSR). This guide, written from a manufacturer’s perspective, explains what duckbill valves are, where they shine, their core advantages, and […]
Valves play a critical role in fluid systems, controlling the flow of liquids, gases, or slurries to ensure optimal operation and safety. Whether used in industrial pipelines, medical devices, or consumer products, valves are essential for maintaining the correct pressure, preventing backflow, and regulating flow rates. Understanding the types, operation, and materials of valves is […]
When OEM engineers and product developers evaluate fluid or air control components, the smallest parts often determine the success or failure of the entire system. At Thesun Industry, we work closely with global OEM customers who face recurring challenges such as leakage, inconsistent cracking pressure, noise, and premature valve failure. One question we hear repeatedly […]
Want a clean, repeatable finish that matches your product spec — not guesswork? Great — you’re in the right place. At Thesun Industry we get asked all the time whether bead blasting or sandblasting is the “better” finishing method. The answer isn’t binary: it depends on your material, tolerance requirements, surface goal, and regulatory/safety constraints. […]
