Challenge
Challenge
Two molded materials had to meet at a controlled boundary while preserving the intended form.
Anonymized case
A two-shot brush-head program focused on interface and appearance consistency.

Challenge
Two molded materials had to meet at a controlled boundary while preserving the intended form.
Approach
Material interface, shot sequence, mold action and trial observations were evaluated together.
Validation
Trial parts were reviewed for boundary appearance, fill condition and part integrity.
Outcome
The anonymized project provides evidence of two-shot brush-head development experience.
