1. Standard Stock Products (Off-the-Shelf Parts)

Our standard catalog parts (such as standard replacement burner nozzles and adapters) are manufactured strictly to the technical blueprints and dimensional specifications published on our website.

Customer Verification Responsibility

Important Note: Before finalizing your purchase, your engineering or maintenance team is strictly responsible for reviewing the dimensional blueprints provided on the product page to self-verify physical compatibility with your machinery. We do not accept returns or refunds for buyer errors, including ordering the wrong model or incorrect dimensional planning.

The Sole Exception for Refunds & Returns

We offer a return, replacement, or refund under one condition only:

  • Blueprint Discrepancy: If the physical product delivered to you deviates from the official technical drawings and dimensional parameters published on our website, and this dimensional mismatch directly makes it impossible for your team to assemble or install the component.

Return Window & Process for Standard Parts

  • Notification Period: You must inspect the delivered goods and report any blueprint discrepancies within 14 calendar days of receiving the package.

  • Proof Required: To initiate a claim, please contact our support team at [Your Contact Email] with high-resolution photos or a video showing CMM (Coordinate Measuring Machine) measurements, caliper readings, or physical assembly interference that proves the dimensional discrepancy.

  • Return Shipping: If we verify that the delivered part deviates from our published specifications, we will provide a replacement at no extra charge or issue a full refund, and we will cover the return express air freight cost.

2. Custom Engineered Products (OEM/ODM / Made-to-Drawing)

Custom parts are manufactured on-demand strictly according to the STEP, CAD, or PDF drawings provided directly by the customer.

Contract-Governed Policy

  • Everything is Contract-Based: All custom fabrication orders require a formal sales contract or purchase agreement signed by both parties prior to production.

  • The Absolute Authority of the Contract: For all custom orders, the policies regarding quality verification, physical tolerances, acceptance testing, remanufacturing, refunds, and returns are strictly governed by the terms and conditions outlined in the signed purchase contract.

  • No Standard Cancellations: Once production begins on custom-machined titanium or aluminum parts, orders cannot be canceled, refunded, or returned unless specified under the executed contract’s terms.

3. Shipping & Inspection Damages

While we package our precision burners and parts using heavy-duty, cleanroom-safe protective materials to prevent damage during international air transit, accidents can happen.

  • If you receive a package that shows obvious external damage, please take photos and videos of the unopened packaging prior to opening it.

  • Inspect the internal nozzle heads immediately. If physical transit damage is found, contact us within 48 hours of delivery with photographic evidence so we can file an immediate claim with the express carrier (DHL/FedEx/UPS) and arrange a priority replacement for you.
