Plastic Mould Steel
Product Description:
Automated Mold Design / External Thread Plastic Injection Mold
External thread plastic injection molds are specifically designed for products with outer threads, such as bottle caps, container lids, and threaded sleeves. These molds require precise engineering to ensure that thread profiles remain intact during demolding and that product dimensions remain consistent.
With expertise in mold development and advanced plastic injection molding, various thread types and custom specifications can be supported. These molds are widely used in everyday consumer goods, medical components, and other industrial applications.
At Sung I Industrial, we offer full custom manufacturing and OEM/ODM services, supported by a vertically integrated production process. This allows us to improve manufacturing efficiency, maintain high quality, and provide cost-effective solutions for threaded plastic parts—making us your ideal partner in thread mold production.
Product Description:
Automated Mold Design / Auto Unscrewing Mold
An auto unscrewing mold is a specialized design where the threaded core rotates automatically to release the plastic part during demolding. This system is ideal for products with external threads and significantly improves production efficiency and stability, making it well-suited for automated plastic injection molding lines.
This technology is widely used in industries that require high-precision and high-speed production. Whether applied in mold development, OEM/ODM manufacturing, or flexible, custom manufacturing projects, auto unscrewing molds play a vital role in optimizing productivity. When integrated into a vertically integrated production process, it allows for streamlined operations, reduced labor, and consistent product quality—making it an essential tool in modern injection molding strategies.
Product Description:
Automated Mold Design / Hydraulic Core Pulling Injection Mold
Hydraulic core pulling injection molds are ideal for plastic parts with undercuts, grooves, or side holes that cannot be ejected by standard means. Using a hydraulic cylinder, the mold activates a core-pulling mechanism to ensure smooth and accurate demolding. This technology is widely used in plastic injection molding for automotive, electronics, and industrial products.
At Sung I Industrial, we offer advanced mold development and custom manufacturing solutions. Whether for OEM/ODM projects or high-precision parts, our molds support complex processes such as insert molding and overmolding, and are compatible with various engineering plastics. Through full vertical integration, we manage everything from design to delivery—ensuring faster lead times, stable quality, and cost control. Hydraulic core pulling molds are essential for manufacturers seeking efficiency, durability, and flexibility in modern injection molding production.
Through its vertically integrated approach, the company streamlines every project phase from design validation to precision fabrication and quality inspection. Their in-house capabilities encompass insert molding, dual-color injection, and intricate part geometries, all supported by data-driven simulations and rigorous ISO-guided controls. adopts environmentally conscious methods, reducing waste and integrating recycled resources to meet modern sustainability goals. As one of the Best tooling product developers in Taiwan, the company continues to offer highly adaptive, customer-centric manufacturing experiences across multiple global sectors.To further support market expansion, the company engages in technical partnerships that bring innovative insights to each new build.
