In 2025, a survey of 412 U.S. and EU manufacturers showed that 68% still struggle with at least one of the following pain points:
- High unit price – Average overmolded part cost is 25% above benchmark due to inefficient tooling.
- Inconsistent quality – Flash defects and uneven cure cause up to 12% scrap rates.
- Slow delivery – Typical lead‑time >45 days, jeopardizing product launch windows.
- Expensive shipping – Heavy, bulk‑packed silicone seals increase freight by 15%.
- Lack of technical support – 41% of buyers report “no OEM/ODM design assistance”.
Imagine a new consumer‑electronics line that must hit the market before the holiday rush, yet you’re waiting 6 weeks for a custom seal. The lost revenue can easily exceed $250,000 per quarter.

Frequently Asked Questions
What is the typical lead‑time for a custom plastic overmolding order?
Standard production runs (≥10 k pcs) are delivered within **10‑14 days** after design approval. Prototypes can be shipped in **48‑72 hours**.

Can you overmold multiple material types in one cycle?
Yes. Our dual‑shot system supports LSR + PC, TPU + ABS, and other hybrid combinations, with temperature‑controlled zones to prevent cross‑contamination.
Do you provide design‑for‑manufacturing (DFM) assistance?
Our in‑house CAD/CAE team offers free DFM review, mold flow simulation, and design optimization to reduce cycle time and material waste.
What certifications guarantee product safety for medical applications?
We hold ISO 13485, ISO 10993‑1, CE‑Mark, and FDA‑registered facilities. All LSR grades are medical‑class II compliant.
How do you handle international logistics and customs?
We offer DDP (Delivered Duty Paid) shipping to the US, EU, and Canada. Our logistics team prepares all export documents, including CE‑Declaration, HS codes, and commercial invoices.
