Forming Process for Cable Assemblies
From design to manufacturing, we maintain close collaboration with you at every stage.
Design Review Process
We will first determine a preliminary design based on the cable drawings you provide. However, during this process, we may request more detailed information to ensure the product meets your specific requirements and performance specifications.
Mold Making
Based on your product drawings, we determine whether to use a single-cavity or multi-cavity mold configuration. For customers requiring different shapes or irregular contours, we can simultaneously customize molds for multiple shapes, enabling efficient production of varied product forms. This flexibility is particularly advantageous for high-volume manufacturing. Of course, we can also optimize production processes for products with a single shape.
Material Selection
Our standard materials offer exceptional adaptability and versatility, making them an ideal choice for most applications. For special requirements involving extreme temperatures or hardness, we can also utilize other types of polyamide compounds to meet your needs.
Forming Process
We utilize fully automated injection molding equipment to deliver highly consistent, premium-quality products. From raw material heating and process parameter adjustment to final overmolding, our technicians provide comprehensive guidance throughout every manufacturing step, ensuring production accuracy and stability.

What Our Customer Say
What is the difference between single-cavity molds and multi-cavity molds?
Single-cavity molds are more suitable for manufacturing larger products. Multi-cavity molds are better suited for smaller products with higher order volumes, as a single mold can produce multiple items simultaneously. This enables rapid production, enhances manufacturing efficiency and delivery cycles, while also reducing manufacturing costs.
What is the difference between molded cable assemblies and overmolded cable assemblies?
Molded cable assemblies are manufactured by fusing cables and connectors into a single unit through injection molding, using rigid plastic or rubber materials. This construction easily withstands harsh environments and offers exceptional durability, making it ideal for industrial, agricultural, or outdoor applications—particularly in settings where moisture, dust, and physical stress are significant concerns.
Overmolded cable assemblies involve adding a protective layer over existing cables and connectors. This additional shielding enhances resistance to stresses like bending or twisting without sacrificing flexibility, making them highly suitable for dynamic applications such as robotics, medical equipment, or environments with repetitive motion.
What is the difference between potting and compression molding or overmolding?
Epoxy resins and potting compounds are liquid sealants that cure over time. They are commonly used to protect connectors from moisture exposure. Molding/overmolding involves permanently fusing materials together under high temperature and pressure, creating a highly durable structure that does not guarantee a complete seal.
What is Shore hardness? Why is it important?
In the hardness scale, Shore hardness measures the stiffness of materials such as rubber or plastic. It is crucial for component design because softer materials (lower Shore hardness) bend easily, while harder materials (higher Shore hardness) resist deformation. We will help you select the appropriate hardness grade for your application.
