How can insert molding help me improve
my next component?
Insert molding can be a highly efficient alternative to the
assembly of discrete parts using soldering, connectors,
fasteners, or adhesives. Its benefits over such methods include:
- Reduced assembly and labor costs
Because insert molding joins numerous components with
thermoplastic, assembly and labor costs are greatly minimized.
For example, a single stamping can be overmolded, then
perforated to create multiple circuit paths.
- Reduced size and weight
By eliminating fasteners and connectors, and by combining the
physical strength of resin and metal inserts, insert molding
yields smaller and lighter components.
- Increased reliability
With every part tightly secured in thermoplastic, an insert
molded component prevents part loosening, misalignment,
improper terminations, and other problems. The thermoplastic
resin also provides improved resistance to shock and
vibration.
- Increased design flexibility
Designers appreciate the virtually unlimited configurations
that insert molding allows. For example, in creating a 3D
circuit board, overmolding permits circuitry to move freely
through the part, from inside to outside, up walls, down in
holes-and the plastic ties it all together.
