Tooling & NDA for OEM Silicone Hose Projects

For automotive OEM silicone hose programs, clear tooling ownership and strict confidentiality form the foundation of every APQP-aligned project. Hotop defines mandrel and tooling rights, storage responsibilities and intellectual-property protection up-front, eliminating ambiguous commercial and legal risks for Tier 1 / Tier 2 serial-production programs.

Tooling & Mandrel Governance

Tooling here refers to custom mandrels, fixtures and dedicated tooling built exclusively for your silicone hose geometry. All tooling-related terms are formalized within project agreements or mutual NDA documents.

Tooling Ownership

• Customer-funded dedicated mandrels & tooling belong solely to the customer upon full payment.
• Hotop-owned tooling applies for Hotop-initiated development or shared-cost programs, clearly stated in the quotation.
• Customer-owned tooling will be uniquely marked for traceability and shall only be used to manufacture parts for your program. No unauthorized third-party production is permitted.

Tooling Storage & Maintenance

We perform routine preventive maintenance for customer-owned mandrels and tooling while stored at our facility. Normal wear-and-tear repair scope, refurbishment costs and service-part retention periods are mutually agreed before tooling fabrication.

End-of-Program Tooling Disposition

Upon program termination or end-of-production, three options are available per written customer instruction:

• Ship tooling back to the customer at the customer’s cost
• Secure long-term archived storage for spare-part production
• Authorized scrapping or destruction only upon the customer’s formal written notice

No customer-owned tooling will be scrapped, reused or transferred without your explicit written approval.

Mutual Non-Disclosure Agreement (NDA)

Before sharing 2D/3D drawings, application specifications or proprietary design data, we execute a mutual non-disclosure agreement, protecting intellectual-property for both parties.

What our mutual NDA covers

• Confidential drawings, CAD files, product specifications, application requirements and project timing
• Project-specific test data, material formulations and silicone hose performance parameters
• Restricted business terms, quotation data and program roadmaps
• Prohibition on disclosing confidential information to any third party without written consent

We accept your corporate standard NDA for review and countersignature. You may also download our standard mutual NDA template for internal review.

What We Avoid

We eliminate common pain points frequently seen in silicone hose OEM cooperation:

• No ambiguous ownership for custom mandrels
• No unapproved reuse of customer-specific tooling for external clients
• No informal verbal commitments; all tooling IP conditions are documented in written agreements

Navigate Within Our OEM Program

This page follows our OEM Workflow, clarifying legal and tooling ground-rules after RFQ and DFM review.

Once tooling and confidentiality terms are settled, proceed to APQP Deliverables to review the complete quality document package scope for your project. After PPAP approval, serial-production activities are governed under Series Production Control. Review real-world program references on our OEM Case Studies page.
