Surface Finishes & Secondary Operations
The mold shapes the part; the finish defines how it looks, feels, and performs. From in-mold SPI/VDI textures to advanced post-molding operations, we provide end-to-end finishing services to turn raw molded parts into production-ready components.

我们如何确保您的塑料零件零缺陷？
We rely on metrology and statistical process control (SPC), not guesswork. First Mold inspects and corrects critical parameters across multiple production stages.
| QA Stage | 我们的方法与设备 | 关键检查要点 |
|---|---|---|
| 1. 前期制作 | DFM审查与Mold Flow分析 | 脱模斜度、壁厚均匀性、浇口位置、焊缝、凹陷、翘曲预测、收缩率、底切、冷却通道布局、排气策略。. |
| 2. 工装与调试 | First-article Inspection (FAI) & T1 Sampling | 尺寸精度、3D CAD 匹配、材料验证、表面光洁度、装配配合度、飞边检测、分型线不匹配、充填不足、顶针痕迹。. |
| 3. 生产中及成品 | CMM & 2d Vision Measurement | 关键公差、复杂几何形状、GD&T（几何尺寸与公差）、平整度、同心度、孔径、轮廓偏差、真实位置、垂直度。. |
| 4. 系统与合规 | 通过ISO认证的规程与可追溯性 | 物料可追溯性、批次间一致性、标准操作规程（SOP）执行、质量控制报告、树脂分析证书（COA）、缺陷最小化、模具维护记录。. |

Our Plastic Injection Molding Workflow at First Mold
We don’t treat your CAD files as a black box. At First Mold, our plastic injection molding process is completely transparent. Here is the exact step-by-step roadmap.
Submit CAD for Engineering Review
Upload your 3D models (STEP/IGES/X_T). Our engineers analyze your geometry and provide an itemized plastic injection molding quote and initial feasibility feedback within 24 hours.
DFM Approval & Mold Fabrication
Review our comprehensive DFM report detailing draft angles, shrink rates, and gating strategies. Upon your sign-off, we immediately begin CNC machining and cutting steel for your custom mold.
T1 Sampling & FAI Verification
We shoot the first physical plastics from your mold. You receive these T1 off-tool samples alongside a complete First Article Inspection (FAI) dimensional report for your engineering validation.
Mass Production & Global Logistics
Once you approve the T1 samples, we lock in the molding parameters for full-scale production. First Mold manages strict SPC quality control, packaging, and direct global shipping to your facility.

Recommended Structural Design Guidelines for Injection Molding
Our engineers highly recommend applying these proven structural parameters to your CAD models to avoid costly mold modifications and achieve flawless parts on the first shot.
- Maintain a uniform thickness (1.5–3.0mm). Keep variations under 20% to prevent sink marks and uneven cooling shrinkage.
- Design internal ribs at 50%–60% of the adjacent outer wall's thickness to prevent visible sink marks on the exterior.
- Avoid sharp internal corners. Add a 0.3–0.5mm minimum radius to reduce stress, prevent cracking, and improve melt flow.
- Apply 0.5°–2° draft on vertical walls. Make the cavity draft 0.5° larger than the core to keep the part on the core during ejection.
- Locate parting lines on the part's maximum contour. Avoid high-gloss or critical assembly surfaces to minimize visible flashing.
- Design text and logos as raised (embossed). Machining recessed text into the mold steel is significantly easier and cheaper than machining raised letters.
- Limit blind hole depth to 3 times the diameter. Deeper holes risk bending or breaking core pins under high injection pressure.
- Do not attach thick bosses directly to main walls. Use connecting ribs and a coring base ("volcano") to prevent exterior sink marks.
- Keep metal inserts ≥5mm from the cavity wall. Preheat them to 80–120°C before molding to prevent thermal stress cracking during shrinkage.
- Add a 0.2–1.0mm cosmetic groove (reveal) at mating lines to seamlessly hide inevitable molding tolerances and mismatch.
- Design mating lips with 0.8–2.5mm depth and 0.1mm side clearance. Keep vertical top and bottom faces at zero gap for a stable fit.
- For reliable assembly, use 1.0–1.5mm cantilever thickness, length under 8x the thickness, and 0.3–0.5mm hook depth.
