Insert Injection Molding
Product Specifications: Threaded Screw + ABS
Product Description:
Leveling Feet / Adjustable Glides
Leveling foot products are widely used in furniture, machinery, and industrial equipment. By using metal insert molding, the threaded screw and ABS plastic base are formed together in a single step, enhancing structural strength and production efficiency while reducing the risk of loosening from manual assembly.
The materials offer high impact resistance, excellent chemical resistance, and strong paint compatibility, making them both functional and visually adaptable.
At Sung I Industrial, we specialize in plastic injection molding and mold development, providing complete custom manufacturing and OEM/ODM services. With our vertically integrated production process, we deliver high-quality, durable, and reliable leveling foot solutions tailored to your application needs.
Product Specifications: Nut+PP/PA6
Product Description:
Car Parts
For automotive plastic components that require superior strength and durability, insert molding is a highly effective solution. This process allows metal nuts to be molded directly into plastic parts in a single step, improving structural integrity and eliminating the need for manual assembly.
It is especially suitable for load-bearing or vibration-sensitive applications such as interior trim and electrical connectors. By using materials with excellent humidity resistance, chemical resistance, impact strength, and abrasion performance, we ensure long-lasting performance in demanding automotive environments. The materials also provide strong heat resistance, electrical insulation, and oil resistance.
At Sung I Industrial, we specialize in plastic injection molding and mold development, offering flexible custom manufacturing and full-service OEM / ODM production. Our vertically integrated workflow ensures efficiency, precision, and consistent quality for every automotive insert molding solution.
