| Feature | Description |
|---|---|
| Maximum Part Size | Typically up to 20” x 20” x 10” (508 x 508 x 254 mm); larger sizes may require multi-shot or manual insert techniques. |
| Standard Lead Time | 4–6 weeks for dual-tooling setup and sampling; shorter for single-shot with pre-molded inserts. |
| General Tolerances | ±0.005”–0.010” (±0.127–0.25 mm), depending on part size, material pair, and bonding surface area. |
| Precision Tolerances | ±0.002” (±0.05 mm) achievable for critical areas (e.g., sealing features), with stable materials and optimized process control. |
| Minimum Feature Size | ~0.020” (0.5 mm), especially for soft overmolded ribs or textured grips. |
| Wall Thickness | Substrate: ≥ 0.040” (1.0 mm); Overmold layer: ≥ 0.020” (0.5 mm). Uniform overmold thickness improves bonding and aesthetics. |
| Draft Angle | 1°–2° for substrate; 3°–5° for overmolded material (especially TPE) to accommodate elasticity and ease of ejection. |
Overmolding combines multiple materials in a single part, often pairing a rigid base with a soft or functional outer layer. At Elite Mold Tech, we apply specialized surface finishing techniques to ensure strong adhesion, aesthetic appeal, and optimal part performance.
