Injection Molding
Insert Molding
Source Insert Molding components through FERRASTACK's audited contract manufacturing network in India.
Insert molding encapsulates metal terminals, busbars, threads, contacts, or shafts within a molded polymer body to consolidate assembly.
- Typical materials
- Engineering thermoplastics and elastomers are molded around brass, copper, steel, stainless, aluminium, or buyer-specified inserts.
- Scale & complexity
- It suits connectors, sensor bodies, fittings, and medical assemblies, with insert geometry, loading method, retention, sealing path, and cavity count defining complexity.
- Tolerance & finishing
- Insert location, flash, resin flow, knit lines, pull-out behavior, electrical spacing, and exposed-surface protection are design-dependent.
- Quality requirements
- Controls can include insert and resin traceability, loading verification, first-article inspection, pull, torque, leak, or electrical tests where specified.
- Why source with FERRASTACK
- FERRASTACK connects buyers to Indian molders able to manage insert manufacture or supply, controlled loading, tool design, and functional inspection.
