How do you select the spring for your application?

Springs are essential components in engineering and various industrial fields. They are used to absorb force, distribute loads, reduce vibrations, and return to their original shape after deformation. Choosing the right spring is crucial to ensure that components and systems function efficiently and reliably. ■ Types of Springs and Their Suitable Applications 1. Compression Springs ✅ Description: Coiled springs that compress when a load is applied and return to their original length when the load is removed. ✅ Applications: Shock absorbers, industrial machinery, automotive components, and electronic devices. 📌 Best for: Load-bearing applications such as car bumpers, engine valves, and household appliances. 2. Extension Springs ✅ Description: Springs that stretch under tension and return to their original shape when the force is released. ✅ Applications: Garage doors, machinery, fitness equipment. 📌 Best for: Applications requiring tensile force, such as door mechanisms and retractable systems. 3. Torsion Springs ✅ Description: Operate by twisting around an axis to provide torque or rotational force. ✅ Applications: Clips, hinges, suspension systems. 📌 Best for: Applications needing rotational force, such as door hinges, paper clips, and furniture mechanisms. 4. Leaf Springs ✅ Description: Made of layered metal strips that can withstand heavy loads and absorb shock effectively. ✅ Applications: Vehicle suspensions, trucks, heavy machinery. 📌 Best for: Heavy-load and impact-absorbing applications. ■ Key Factors in Selecting the Right Spring 1. Spring Material The choice of material affects strength and durability: - Stainless Steel – Corrosion-resistant, ideal for humid or corrosive environments. - Carbon Steel – Strong and suitable for high-load applications. - Alloy Steel – Suitable for high-temperature environments. 2. Size and Load Requirements Consider diameter, number of coils, and spring rate to ensure the spring can handle the required load effectively. 3. Operating Environment and Temperature - For high temperatures, use materials like Inconel or Stainless Steel. - For chemical resistance, choose springs with coated or corrosion-resistant materials. 4. Durability for Long-Term Use For applications with frequent repetitive loads, use springs that have undergone heat treatment to extend lifespan.

What is Plastic Insert Molding?

■ A Precision Technology for Combining Metal and Plastic in High-Performance Parts Plastic insert molding is a specialized injection molding process where metal or other material components (inserts) are placed into the mold cavity before molten plastic is injected. Once the plastic cools and solidifies, the inserts are securely embedded within the plastic, resulting in a single, integrated part. This method enhances the durability, functionality, and structural integrity of the final product, making it ideal for applications requiring strength and precision. ■ How Insert Molding Works The process begins by preparing the inserts—typically made from materials such as steel, brass, or copper. These inserts are placed in designated positions within the mold either manually or using automation. Once the mold is closed, molten plastic is injected into the mold cavity. The plastic flows around the inserts, encapsulating them. After cooling, the result is a unified component combining the properties of both metal and plastic. ■ Key Benefits of Insert Molding - Enhanced durability: Parts are more resistant to mechanical stress compared to pure plastic components - Streamlined manufacturing: Reduces the need for separate assembly steps - Time and cost efficiency: Saves labor and improves production throughput - Improved precision: Achieves tight tolerances and consistent insert positioning - Design flexibility: Allows for integration of multiple functions into a single part ■ Common Applications of Insert Molding Insert molding is widely used across various industries, including: - Electronics: Connectors, relay bases, sensor housings - Automotive: Wire harness holders, electrical component casings - Medical: Lightweight yet strong medical device components - Consumer Electronics: Structural parts that combine plastic with conductive or threaded metal inserts ■ Why Choose Bangkok Sanyo Spring for Insert Molding Bangkok Sanyo Spring Co., Ltd. specializes in high-precision insert molding using state-of-the-art machinery and strict quality control systems.
