Manufacturing Capabilities
Compression molding, cryogenic trimming, and in-house toolmaking — all under one roof.
Company Overview
We are a vertically integrated O-ring manufacturer, not a trading company. Our facility handles compounding, mold fabrication, compression molding, flash removal, inspection, and packaging internally. This integration is what allows us to offer custom sizes with no mold fees, fast prototyping, and consistent quality.
Production Process
Material Mixing
Raw polymer, fillers, curatives, and accelerators are weighed and mixed on internal mixers and two-roll mills to precise compound recipes.
Compression Molding
Preforms are loaded into heated steel molds and cured under pressure. This is our primary molding method for NBR, FKM, EPDM, and Silicone.
Cryogenic Trimming
Flash is removed via cryogenic tumbling or precision auto-trim equipment, preserving seal edge integrity — critical for dynamic seals.
100% Visual Inspection
Operators inspect each part for parting-line flash, voids, contamination, and dimensional anomalies before release.
Final QC & Packaging
Hardness and spot-check dimensions are recorded on the batch report. Parts are counted, bagged, labeled, and boxed for shipment.

Capability Highlights
No Mold Fees (Standard Profiles)
For standard cross-sections, we absorb tooling costs. You only pay for the parts.
Prototype to Production
First article samples in 3-5 days. Production ramp-up within 7-15 days standard lead time.
Custom Cross-Sections
Any inner diameter × cross-section combination. We also manufacture square-cut rings, X-rings, and special profiles.
Small Batch Friendly
MOQ starts at 1 piece. Whether you need 10 pieces for R&D or 100,000 for production, the process is the same.
Frequently Asked Questions
What molding process do you use?
Compression molding is our primary process for O-rings. It provides excellent cavity fill, tight flash control, and is cost-effective for both small and large production runs.
Do you make your own molds?
Yes. Our in-house mold shop machines tooling for standard AS568 and ISO 3601 sizes as well as custom profiles. This eliminates third-party tooling delays and hidden costs.
Can you manufacture non-standard sizes?
Yes. We can produce any inner diameter and cross-section combination. For custom profiles, we machine the mold in-house and typically deliver samples within one week.
What is your typical lead time?
Standard lead time is 7-15 days from order confirmation to shipment. Express prototyping is available in 3-5 days for urgent validation work.
