Reduce Production Costs by 25% in 60 Days with Premium Injection Overmolding—Risk‑Free Sample
For Purchasing Managers, Technical Directors & Operations Leaders who struggle with high‑price, low‑quality silicone parts and slow delivery, Yingtai delivers high‑speed, high‑quality custom injection overmolding services that meet ISO‑9001, CE, FCC and RoHS standards.
Why Your Current Suppliers Are Holding You Back
In 2024‑2025, more than 68% of B2B buyers reported that price volatility and long lead‑times are the top blockers to scaling new product lines. Here are the three core pain points you likely face:
- High Unit Cost – Overseas factories often add hidden fees for material handling, customs clearance, and quality re‑work, inflating your bill of materials by up to 30%.
- Inconsistent Quality – Variations in cure temperature and mold venting cause flash, shrinkage, and premature failure, especially for liquid silicone rubber (LSR) overmolded seals.
- Slow Delivery & Expensive Shipping – Standard sea freight adds 30‑45 days; air freight is costly, pushing ROI beyond acceptable thresholds.
According to the Grand View Research LSR market report, the sector will reach USD 4.97 billion by 2030, yet many suppliers cannot keep up with the required high‑precision silicone overmolding demand.
Yingtai’s Competitive Edge in Injection Overmolding
Our Powerful Factory combines 55 liquid silicone molding machines and 80 automatic plastic injection machines, enabling high‑speed delivery and consistent, ISO‑9001‑certified quality. Below are the core advantages you gain:
- Full‑Chain OEM/ODM Design – From CAD‑based mold design to finished overmolded product, all in‑house.
- Rapid Tooling – 3‑week prototype molds using CNC‑machined aluminum, cutting typical lead‑times by 50%.
- Precision Control – Real‑time temperature, pressure, and cure‑time monitoring with AI‑driven process optimization (see AI study).
- Scalable Volume – From 1 k to 1 M+ units per month without sacrificing tolerances.
- Cost Transparency – Fixed‑price quoting, FOB, EXW, DDP options, and free sample shipping.

Frequently Asked Questions
What is the typical lead‑time for a custom injection overmolding order?
For standard LSR parts, prototype tooling can be delivered in 3‑4 weeks. Full‑scale production starts within 6‑8 weeks after design approval.
Can you handle multi‑material (dual‑shot) overmolding?
Yes. We offer low‑temperature LSR combined with high‑temperature PC/ABS in a single cycle, reducing handling steps and ensuring strong inter‑layer adhesion (MDPI study).
How do you ensure quality compliance for medical‑grade silicone?
All medical‑grade LSR batches are processed in a cleanroom (ISO 7) environment, tested for biocompatibility (ISO 10993), and documented with FDA‑510(k) supporting data.
What logistics options are available for international shipments?
We provide FOB, CIF, DDP and express air‑freight. For high‑value medical kits we can arrange temperature‑controlled containers.
Do you offer post‑sale technical support?
Our after‑sales team provides 24/7 online troubleshooting, on‑site training, and a 12‑month warranty covering material defects and dimensional drift.
