Most B2B buyers in the U.S. and EU report three recurring pain points:
- High Unit Cost – Single‑color molds force you to buy separate parts and assemble them, adding 15‑25% extra labor.
- Long Lead‑Times – Shipping whole assemblies from China adds 4‑6 weeks to the schedule.
- Quality Inconsistencies – Mismatched colors or delamination cause 30% higher reject rates in medical‑grade batches.
According to the Grand View Research LSR market report (2023), manufacturers that adopt dual‑color injection molding see a 22% reduction in total cost of ownership within the first year.

Frequently Asked Questions
What is the minimum order quantity for two color injection molding?
We accept prototype runs as low as 500 pcs. For mass production, the typical MOQ is 10 k pieces, which allows us to amortize tooling costs effectively.
Can I use two different materials (e.g., LSR + PC) in one part?
Yes. Our dual‑shot capability supports LSR overmolded onto hard plastics such as PC, ABS, or POM. We apply surface activation (plasma or corona) to ensure bond strength ≥ 1.2 MPa.
How do you guarantee color consistency across large batches?
Our in‑house spectrophotometer calibrates pigments per ISO 11664‑4. We also provide a color‑match certificate for each batch, and a 30‑day warranty against shade deviation.
What are the typical lead‑times for tooling and production?
Standard two‑cavity molds: 4‑6 weeks for design, CNC machining, and EDM. Production after tooling can start in 7‑10 days for prototypes and 3‑5 weeks for volumes ≥ 10 k pcs.
Do you ship internationally and handle customs clearance?
Yes. We offer DDP (Delivered Duty Paid) to the US, EU, and Canada. Our logistics team prepares all required CE, FCC, and customs documentation.
