In 2026, corporate buyers demand faster time‑to‑market, lower total cost of ownership, and proven compliance. Our two component injection molding service combines liquid silicone rubber (LSR) and engineering thermoplastics in a single, synchronized cycle—delivering parts that are both soft‑touch and structurally rigid.
The Pain Points You’re Facing Today
- High price of overseas suppliers – up to 30 % above local quotes.
- Low quality resulting in warranty claims – average return rate of 4.2 % for multi‑material parts.
- Slow delivery speed – typical lead times of 8‑12 weeks for two‑shot molds.
- Expensive shipping and customs delays for bulk silicone loads.
- Uncertainty around compliance (CE, ISO 9001, RoHS) for medical‑grade components.
According to the Grand View Research LSR market report, the global LSR market will reach USD 4.97 billion by 2030, driven by demand for precision‑engineered silicone‑plastic hybrids. Yet 62 % of buyers still cite “supplier reliability” as the top barrier.
Our Two Component Injection Molding Solution
Yingtai’s end‑to‑end platform integrates 55 liquid silicone molding machines and 80 automatic plastic injection units in a single production line. The result is a seamless, high‑speed process that guarantees ≤ 0.02 mm dimensional variance and ≤ 0.5 % cycle‑time deviation.
Core Advantages (1‑6)
- Fast Turn‑Around: 2‑shot molds ready for pilot runs within 3 weeks.
- Cost‑Effective Tooling: Modular steel/aluminum inserts cut tooling cost by 35 %.
- Quality Assurance: In‑line vision inspection + AI‑driven defect prediction (arXiv 2025).
- Regulatory Compliance: CE, ISO 9001, RoHS, FDA‑registered LSR grades.
- Design Flexibility: Over‑molded seals, soft‑touch grips, embedded sensors.
- Environmental Stewardship: Waste‑reduction process saves up to 12 % material per batch (Fraunhofer 2024).

Application Scenarios & Case Studies
1. Medical Wearables – A US‑based med‑tech company needed a soft‑touch sensor housing with embedded PCB. Yingtai delivered 150 k units in 6 weeks, cutting their previous 12‑week lead time by 50 %. Defect rate dropped to 0.18 % after AI‑based process tuning.
2. Automotive Interior Seals – A German OEM required high‑temperature resistant LSR over‑molded to polycarbonate for dashboard trim. Our low‑temperature cure LSR (130 °C) reduced cycle time by 1.2 s and saved 8 % energy per part.
3. Consumer Electronics – A European smartphone accessory brand sourced soft‑grip cases with integrated antenna windows. Using our modular molds, they achieved 30 % weight reduction and passed RoHS compliance on first trial.

Frequently Asked Questions
What is the typical lead time for a two component injection molding project?
From design validation to first‑article production, most projects complete in 4–6 weeks. Rapid‑tooling options can shave another week.
Can I customize material grades for both components?
Yes. We stock over 30 LSR grades (medical, food‑contact, high‑temperature) and 25 engineering plastics. Custom blends are available upon request.
How do you ensure bonding strength between silicone and plastic?
We use surface activation (plasma, corona) and optimized cure profiles. Our process yields > 0.9 MPa peel strength, verified by ISO 11339 testing.
What are the shipping and logistics options for bulk orders?
We offer FOB, CIF, and DDP. Our warehouse in Hamburg handles EU customs clearance; in the U.S., we partner with UPS Freight for LTL shipments under 40 ft containers.
Do you provide post‑sale technical support?
Yes. A dedicated application engineer is assigned to each account, offering 24/7 remote diagnostics, on‑site training, and a 12‑month warranty on tooling.
