Plastic Injection Molding
Precision molding for small and medium-sized plastic components.
Core services and molding capabilities
Jie Li Plastics specializes in stable, high-volume production of small and medium-sized plastic parts. Our experience in process tuning and automated production helps control dimensions and meet the requirements of precision mechanical components. Standard maximum part size: up to 200 mm per part. Micro-molding capability: fine assembly components as small as 1 mm. For special elongated shapes or geometries, Jie Cheng Mold can plan mold structures and gate locations to allow molding lengths beyond the standard 200 mm limit. Feasibility is evaluated for each design.
Secondary processing and precision assembly
Printing and marking: screen printing and pad printing for logos, specifications and alignment markings. Metal and hardware insertion: precision hardware, threaded nuts and metal terminal assembly for connectors and electromechanical components. Multi-material assembly: fitted composite structures, such as transparent PP housings with solid-color ABS inner supports, with attention to flash, fit and unwanted movement. Ultrasonic and special joining: processes for products requiring sealing, water resistance or specialized structures, subject to design evaluation.
Applications across industries
Explore memory card storage accessories, precision connectors and wiring components, electronic enclosures, medical components and everyday products. For food-contact applications, we select suitable non-toxic plastics according to the required food-grade specifications and confirm the applicable FDA or SGS documentation with the customer.
