Get Your Free Quote in 24 hThe Real Pain Behind Your Silicone Procurement
When you source liquid silicone rubber (LSR) parts from generic suppliers, three‑to‑six critical issues emerge:
- Excessive Unit Cost – Most offshore factories charge a 15‑30% premium for “premium” grades that often fail to meet true medical or automotive specifications.
- Inconsistent Mechanical Performance – Tensile strength, elongation at break, and hardness can vary > 20% batch‑to‑batch, leading to warranty claims and field failures.
- Long Lead Times – Typical delivery windows exceed 8‑12 weeks, jeopardizing product launch schedules.
- High Shipping Expenses – Air freight for delicate silicone components can add $2‑4 per kg, inflating total landed cost.
- Lack of Certification Transparency – Without CE, ISO‑9001, or FDA proof, you risk non‑compliance in regulated markets.
- Poor Technical Support – Suppliers often lack design‑for‑manufacturability (DFM) guidance, forcing you to redesign after tooling.
Data point: According to the Grand View Research LSR market report, 68 % of manufacturers cite “lead‑time uncertainty” as the top barrier to scaling silicone components.
See How We Solve ItWhy Yingtai Is the Premium High‑Quality LSR Injection Molding Manufacturer You Need

Frequently Asked Questions
What is the typical lead time for a 10,000‑unit LSR order?
Standard production (no custom tooling) ships in 12‑14 days after artwork approval. Custom molds add 3‑4 weeks.
Can you provide FDA‑registered material certificates for medical‑grade LSR?
Yes. All medical‑grade batches come with FDA 510(k)‑compliant certificates, ISO 13485 audit reports, and biocompatibility test data.
