Your One‑Stop LSR Partner – Precision, Speed, Compliance
We specialize in **custom LSR molding services** for OEM/ODM projects, delivering high‑volume LSR injection parts in as fast as 15 days from design approval.
Why Your Current Silicone Supply Is Holding You Back
- High Unit Cost: Imported LSR often carries a 20‑30% premium due to limited scale and shipping fees.
- Inconsistent Quality: Variations in viscosity and cure time lead to flash defects and dimensional drift.
- Slow Lead Times: Traditional Asian factories quote 6‑8 weeks, jeopardizing product launches.
- Regulatory Uncertainty: Missing CE/FCC/ISO documentation can stall market entry in Europe and the USA.
- Limited Design Flexibility: One‑shot molds restrict multi‑material overmolding needed for soft‑touch electronics.
According to Grand View Research, the global LSR market will reach USD 4.97 billion by 2030 – a clear sign that demand for fast, reliable supply chains is exploding.
Our Competitive Edge – What Sets Our LSR Manufacturing Apart
- State‑of‑the‑Art Equipment: 55 liquid silicone molding machines, 80 injection presses, and 30+ precision testing instruments.
- Full‑Chain Control: From CAD‑driven mold design to finished part inspection – all under one roof.
- OEM/ODM Flexibility: Custom compounds (medical‑grade, food‑contact, high‑temp) and multi‑shot overmolding.
- Fast Turn‑Around: 15‑day prototype, 30‑day volume production with high‑speed delivery via air freight.
- Zero‑Risk Sampling: Free 5‑piece sample kit with performance data sheet.
- Compliance Assurance: ISO 9001, CE, FCC, RoHS, GS, VDE, SAA, and GMP certifications.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom LSR parts?
We accept prototypes as low as 5 pieces. For volume production, the MOQ starts at 10 k units, but we can negotiate lower runs with multi‑shot tooling.
Can you provide medical‑grade LSR that complies with FDA 21 CFR Part 177?
Yes. Our FDA‑registered production line produces Class II devices with ISO 13485 documentation and full biocompatibility test reports.
How do you ensure dimensional stability across large batches?
We use advanced material characterization (rheology & DSC) combined with AI‑driven process optimization (see arXiv study) to keep shrinkage < 0.15 % across 100 k+ parts.
What logistics options are available for international shipments?
We offer air freight (24‑48 h), sea freight (FOB or CIF), and DDP door‑to‑door service. All shipments are accompanied by a full set of compliance certificates.
Do you provide design‑for‑manufacturing (DFM) support?
Our in‑house CAD/CAE team works with you from concept to mold, using simulation tools to reduce cycle time and scrap.
Limited‑Time Offer: Free 5‑Piece Sample Kit + 10% Off First Production Run
