Why Your Current Supplier Might Be Holding You Back
1. Sky‑High Unit Prices – Most offshore factories charge a 15‑30 % premium for “premium‑grade” LSR because of low‑volume tooling and hidden logistics fees.
2. Inconsistent Quality – Reports from North‑American OEMs show a 22 % defect rate (flash, air bubbles, dimensional drift) when suppliers lack proper rheology data 【9】.
3. Lengthy Lead Times – Average delivery from China exceeds 45 days, jeopardizing product‑to‑market schedules for fast‑moving consumer electronics.
4. Expensive Shipping & Customs – Heavy silicone batches incur > $2 kg⁻¹ freight, plus unpredictable duties.
5. Limited Design Flexibility – Many factories cannot handle multi‑shot or over‑molded assemblies, forcing you to split orders across multiple vendors.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom silicone injection molding?
Our standard MOQ is 2 000 pcs per part, but we can run a pilot batch of 500 pcs using rapid‑tooling to validate design and material selection.
Can you produce medical‑grade LSR components that meet FDA 21 CFR 177.2600?
Yes. All medical‑grade batches are processed in a dedicated cleanroom, with full traceability and FDA‑approved material certificates.
How long does tooling take for a new design?
Standard steel molds: 4‑6 weeks. For fast‑track projects we offer 3‑D‑printed aluminum molds in 7‑10 days, suitable for up to 100 k cycles.
What shipping options are available for bulk orders?
We provide FCL, LCL, air‑freight, and door‑to‑door DDP services. Our logistics team optimizes packaging to keep freight under $1.5 /kg.
Do you offer post‑production support or warranty?
All parts carry a 12‑month warranty against material defects. We also provide on‑site troubleshooting and free redesign assistance for the first 2 months.
