Frequently Asked Questions
Single-cavity molds – ideal for larger products, producing one part per cycle
Multi-cavity molds – designed for smaller products with high order volumes, allowing a single mold to produce multiple parts simultaneously, which accelerates production, improves efficiency, shortens delivery times, and reduces manufacturing costs
- Molded cable assemblies – created by fusing cables and connectors into a single unit using hard plastic or rubber through injection molding. They are highly durable and resistant to moisture, dust, and physical stress, making them ideal for industrial, agricultural, and outdoor applications.
- Overmolded cable assemblies – involve adding a protective layer over existing cables and connectors, enhancing stress resistance (bending, torsion) while maintaining flexibility. These are perfect for dynamic applications, including robotics, medical devices, and environments with repetitive motion.
This differentiation helps OEMs select the right solution for high-stress, high-performance, and industry-specific requirements, ensuring reliability and long service life.
- Potting – uses epoxy resins or potting compounds, which are liquid sealants that cure over time. Potting primarily protects connectors from moisture and humid environments, providing insulation and environmental protection.
- Compression molding/overmolding – permanently fuses materials together under high temperature and pressure, creating a durable structure. While extremely strong, this method does not always provide a completely airtight seal.
This distinction helps determine the best protection method for connector reliability in different environmental conditions.
- Shore hardness measures the stiffness of materials like rubber or plastic.
- It is critical in component design: softer materials (lower Shore hardness) offer flexibility, while harder materials (higher Shore hardness) resist deformation.
WIRES helps select the optimal hardness grade for your application. Our proactive service has earned the trust of over 300 clients, delivering approximately 2 million wire harnesses to date, ensuring reliability and performance across industries.
