Мы не используем автоматизированные онлайн-инструменты котировки, потому что они очень неточны. Онлайн-платформы для расчета расценок опираются исключительно на расчеты, основанные на суммах резки и фиксированных коэффициентах, они не учитывают реальные нюансы обработки, например, деформация материала после термообработки, жесткие требования к допускам, шлифовка после термообработки и т.д. Следовательно, автоматические расчеты цен могут привести к неточностям, что в конечном итоге увеличит ваши расходы.

What is Insert Molding?
Insert molding is a process where plastic is molded around another part, usually made of metal. You place the insert, like a pin, screw, or connector, into a mold, and then molten plastic is injected around it. Once it cools, you get one solid part with both materials tightly bonded. This makes the part stronger, more compact, and reduces the need for extra assembly steps like gluing or fastening.
You can use insert molding to improve product strength, save time, and create cleaner designs. It’s often used in medical devices, electronics, automotive parts, and consumer products. At DEK, we help you choose the right insert, material, and mold design to make sure everything fits and performs exactly as needed.
What are the Advantages of Insert Molding?
Insert molding offers several benefits when you need strong, precise, and reliable parts. It helps improve performance and reduce production time, especially for complex components. You also get better consistency between parts, which is important for high-volume or safety-critical applications.
Ключевые преимущества:
- Improved strength at stress points
- Better durability and part life
- Reduced assembly time and labor
- Compact, space-saving designs
- Lower risk of part failure
- Cost-effective for any volume
When Do You Need Insert Molding?
You need insert molding when your part requires added strength, durability, or built-in metal features like threads, pins, or contacts. It’s a good choice when you want to simplify your product design without adding extra steps after molding. This process is especially helpful when your parts face repeated use or mechanical stress. It’s commonly used in parts for connectors, handles, housings, and enclosures where metal and plastic must work together.
Insert molding is also useful when you need to improve part quality and reduce errors during production. It gives you better control over fit, alignment, and performance—especially for high-precision or safety-critical applications. You get a cleaner build and fewer weak points in your final product.
