Controlled Production for Custom Sealing Profiles
A practical B2B workflow for rubber, foam, PVC, silicone and brush profiles—from drawing review and sample approval to production checks and export packing.

From RFQ Review to Export Shipment
Inspection points are agreed around the product drawing, approved sample and application requirements.
Requirement Review
Confirm application, cross-section, dimensions, material, quantity, joining, adhesive and packaging needs.
Tooling & Sample
Review manufacturability, prepare tooling when required and produce a sample for dimensional and fitting evaluation.
Sample Approval
Record the agreed profile, critical dimensions, appearance and packing details before bulk production.
Production & Packing
Run production against approved requirements, complete agreed checks and prepare labeled export packaging.
What to Include in Your RFQ
- Perpendicular cross-section drawing or clean physical sample
- Critical dimensions, tolerances and mating-part measurements
- Application photos and operating environment
- Material, hardness, color and surface requirements
- Roll length or cut length, annual demand and first-order quantity
- Labels, cartons, pallets and required inspection documents
Why This Matters
A complete RFQ reduces profile selection errors and helps both sides define measurable acceptance criteria before production.
For replacement seals, include an uncompressed sample and photos showing the installed position.
Typical Production Checkpoints
The exact inspection plan depends on the profile, application and buyer requirements.
Material & Batch Identification
Define the required material family, hardness or density target and any project-specific documentation before production.
Cross-Section & Dimensions
Compare the extruded section and agreed critical dimensions with the approved drawing or reference sample.
Surface & Secondary Operations
Review visible surface condition, adhesive placement, flocking, carrier position, joining or cutting when applicable.
Length, Quantity & Packing
Confirm roll or cut length, quantity, labels, carton arrangement and pallet requirements before shipment.
Real Production, Tooling and Inspection Activities
Authenticity note: The photographs below were supplied by Onaseal and show actual production equipment, tooling storage and factory operations. Individual processes vary by profile and order requirements.

Profile Extrusion & Curing
Continuous production equipment supports sealing-profile extrusion and controlled downstream processing according to the approved profile requirements.

Custom Extrusion Tooling
Organized extrusion dies support profile development from drawings or physical samples, subject to tooling and manufacturability review.

Rewinding & Visual Inspection
Operators monitor finished rolls during rewinding and packing preparation; agreed dimensions and acceptance checks depend on each order.
Keep the Approved Profile as the Reference
For repeat production, buyers should identify the approved drawing revision, reference sample, material requirement and packaging version. Any requested change should be reviewed before the next production batch.
Project-specific records, inspection frequency and acceptance limits should be agreed in writing because different profiles and industries require different controls.
Documents to Discuss During RFQ
- Approved drawing or profile specification
- Sample approval record
- Dimensional inspection requirements
- Material documentation requested by the buyer
- Packing specification and label artwork
Business Registration Information
Zhuhai Onaseal Technology Co., Ltd. is presented as a limited liability company established in Zhuhai, Guangdong, China on June 1, 2023. Registration information was supplied by the business owner for website identity review.
The original registration document is not published on this website because it contains personal, address and machine-readable information. Buyers may request appropriate company information during supplier verification.
Supplier Verification
- Confirm the legal company name on quotations and contracts
- Match bank and beneficiary information before payment
- Request project-specific inspection documents during RFQ review
- Do not rely on website images alone for supplier qualification
Manufacturing & Quality Questions
Provide a perpendicular cross-section drawing or sample, critical dimensions, application photos, material preference, quantity and packaging requirements.
A sample approval step can be included so profile fit, dimensions and application performance are reviewed before bulk production.
Available inspection records and documentation depend on the product and agreed quality plan. State required records during RFQ review.
