Applicable Molding Processes for ABS
ABS offers excellent dimensional stability and chemical adhesion, making it highly compatible with advanced molding configurations:
| 成形プロセス |
プロセス適合性と用途 |
| 標準射出成形 |
Excellent. Highly suitable for structural housings, keyboards, domestic appliance shells, and toys requiring precise snap-fits. |
| Overmolding / 2K Molding |
Excellent. Often used as the rigid substrate overmolded with soft TPE or TPU to create hand-grips, aesthetic borders, and tactile power buttons. |
| インサート成形 |
Excellent. Brass knurled nuts, electronic terminal connectors, and metal brackets can be seamlessly insert-molded to enhance mechanical fastening. |
ABS Injection Molding Manufacturing & Tooling Guide
While ABS is generally forgiving to process, maintaining cosmetic excellence and high dimensional repeatability demands scientific process controls:
- 予備乾燥: ABS is moderately hygroscopic and will absorb atmospheric moisture. We strictly pre-dry ABS resin in desiccant dryers at 80°C–85°C (176°F–185°F) for 2–4 hours to prevent splay, cosmetic silver streaks, and mechanical weakening.
- 溶融温度: Processed between 200°C and 240°C (392°F to 464°F). For flame retardant (FR) grades, we limit melt temperatures to 230°C to prevent thermal degradation of FR additives.
- 金型温度: Kept between 40°C and 80°C (104°F to 176°F). Higher mold temperatures improve flow, reduce molded-in stresses, and elevate the final part’s surface gloss.
- 抜き勾配: Due to ABS’s rigid nature, draft angles of 1.5° to 2° are recommended to facilitate clean ejection without drag marks, particularly on textured surface finishes (e.g., MT11010).
- Shrinkage Calculation: ABS exhibits low and predictable shrinkage (typically 0.4% to 0.7%). Our tooling division utilizes 5-axis CNC machining to cut mold cavities with precise scaling, ensuring tight dimensional tolerances.
Key Application Industries for Molded ABS Parts

- 家庭用電化製品: Desktop printer housings, gaming console shells, remote controls, keyboards, router enclosures, and phone bezels.
- Medical Housings (ISO 13485 Compliant): Handheld diagnostics covers, laboratory device casings, medical monitor bezels, and non-invasive equipment handles.
- 消費財・玩具: Rigid toy blocks, kitchen appliance enclosures, power tool housings, suitcases, and structural storage organizers.
