Your One‑Stop Source for Custom Silicone Gaskets
Eliminate leakage, reduce maintenance costs, and accelerate product rollout with gaskets engineered for your exact dimensions, durometer, and chemical resistance.
Why Traditional Gasket Suppliers Keep You Up at Night
- High Unit Price: Off‑shore OEMs often charge a 30‑40 % premium for low‑volume orders.
- Inconsistent Quality: 12 % of buyers report dimensional drift > 0.2 mm, leading to seal failure.
- Slow Lead Times: Average 8‑12 weeks from design approval to shipment.
- Expensive Shipping: Air freight for 50 kg of silicone can exceed $1,200.
- Regulatory Gaps: Missing CE, ISO‑9001, or RoHS certificates jeopardize market entry.
According to Grand View Research, the global LSR market will reach $4.97 billion by 2030—yet 48 % of manufacturers still struggle with “quality‑first” sourcing. Don’t let these bottlenecks erode your ROI.
Our Competitive Edge – Precision‑Engineered Custom Silicone Gaskets
- Factory‑Integrated Design → Production: 55 LSR molding machines, 80 injection presses, and 30+ precision testing instruments.
- ISO‑9001, CE, RoHS, FDA, GS Certified: Full compliance for medical, automotive, and food‑contact applications.
- OEM/ODM Flexibility: From 5 mm×5 mm micro‑gaskets to 500 mm×500 mm industrial seals.
- Rapid Turn‑Around: 2‑week prototyping, 4‑week volume production for orders ≥5,000 pcs.
- Cost‑Effective Shipping: Consolidated sea‑freight under $0.15 per kg for EU/US destinations.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom silicone gaskets?
Our standard MOQ is 5,000 pcs, but we can run a pilot batch of 1,000 pcs using rapid tooling at a slightly higher unit cost.
Can you provide material data sheets for FDA‑grade silicone?
Yes. All FDA‑compliant grades come with a full Material Safety Data Sheet (MSDS) and compliance certificates (ISO 13485, USP <801>).
How long does tooling take for a new gasket design?
Standard steel molds require 3‑4 weeks; aluminum rapid‑tool molds can be delivered in 10‑12 days, enabling a 2‑week prototype cycle.
Do you support multi‑material over‑molding (e.g., silicone over ABS)?
Absolutely. Our dual‑shot injection line handles LSR + ABS, LSR + PC, and LSR + TPU with optimized surface‑activation processes (see MDPI study).
What logistics options are available for US/EU customers?
We offer DDP sea‑freight (average 28 days, $0.12/kg), air‑freight ($0.85/kg for urgent orders), and customs‑clearance assistance.
Ready to Eliminate Leak‑Related Downtime?
Limited Offer: First 100 pcs shipped with free 30‑day performance guarantee and no tooling surcharge for orders placed before 31 May 2026.
