Manufacturing Services Terms & Conditions

Manufacturing Services Terms & Conditions

Last Updated: 1/29/2026

These terms and conditions govern all custom manufacturing, CNC machining, and prototyping services provided by McChine LLC (the "Company"). By accepting a quote or issuing a Purchase Order, the Client agrees to be bound by the following:

1. Quotations and Pricing

• Validity: All quotations are valid for 30 calendar days from the date of issue, unless otherwise specified in writing.

• Material Fluctuations: Due to the volatility of raw material markets (Aluminum, Stainless Steel, High-Performance Plastics), the Company reserves the right to requote if material costs increase by more than 10% between the time of quote and the time of order.

• Minimum Order: The Company reserves the right to apply a Minimum Order Charge to any custom project to cover setup and programming overhead.

2. Technical Data and Specifications

• Primary Source of Truth: The Company machines parts based on the 3D models and 2D drawings provided by the Client. In the event of a discrepancy between a 3D model and a 2D drawing, the 2D PDF print shall be considered the primary authority for tolerances and finishes.

• Design Responsibility: McChine LLC is a contract manufacturer. We do not provide engineering certification or guarantee the functional performance of the Client’s design. The Client is solely responsible for the "Design for Function."

3. Quality and Tolerances

• Standard Tolerances: Unless specifically noted on the provided print, the Company’s default manufacturing tolerances are:

  • Linear: ± .005"

  • Angular: ± 1°

• Precision Requirements: Tolerances tighter than standard (e.g., ± .0005") must be explicitly identified in the Request for Quote (RFQ) and confirmed by the Company in writing.

• Surface Finish: Standard "as-machined" finish is approximately 125 Ra (63 Ra on some geometries) unless otherwise specified.

4. Client-Supplied Material

• If the Client provides raw material or "slugs" for machining, the Company is not liable for costs associated with material flaws, internal stresses, or incorrect material sizing.

• In the event of a "machine crash" or tool failure on Client-supplied material, the Company’s liability is limited to the loss of machining labor only. The Company will not reimburse the cost of the raw material.

5. Inspection and Acceptance

• First Article Inspection (FAI): Available upon request for an additional setup fee.

• Claims: The Client has 10 business days from the receipt of parts to inspect and report any non-conformances. After 10 days, the parts are deemed accepted.

• Liability Limit: The Company’s maximum liability for any non-conforming part is limited to the repair or replacement of the part, or a refund of the machining cost. McChine LLC is not liable for any "downstream" costs, including lost project time, assembly labor, or shipping delays.

6. Confidentiality and Intellectual Property

• NDA Clause: McChine LLC treats all Client drawings, models, and proprietary data as Strictly Confidential. We will not share, sell, or disclose your designs to any third party without express written consent.

• Portfolio Usage: Unless the Client explicitly opts out in writing, the Company reserves the right to photograph non-proprietary parts for use in its marketing portfolio.

7. Cancellations and Returns

• Custom manufactured parts are non-returnable.

• Orders cancelled after material has been purchased or programming has begun will be subject to a cancellation fee covering costs incurred up to the point of cancellation.
