Before CNC machining, our six engineers with more than 20 years of experience will conduct DFM analysis to discover and solve potential problems in advance. This ensures optimized design, efficient manufacturing, and effectively reduces machining costs.
Check part dimensions against tolerance specifications, assess the design’s manufacturability, and enhance production to achieve your desired balance of quality and cost.
We source raw materials from trusted long-term suppliers, ensuring consistent quality and reliability. Third-party inspection reports from organizations like SGS, CTI, and TUV are available to guarantee material compliance and standards.
We have an independent department to track the progress of orders and maintain detailed records of each production batch. The machining photos and videos will be transparently shared with customers at any time to let customers know the progress of product machining at any time.
Dimensional tolerance inspections are conducted every two hours,, with first-article and IPQC inspections to ensure stable processes and consistent quality.
Conduct statistical analysis to monitor and control the manufacturing process and provide inspection reports.
If any deviations, defects or non-conformities are discovered while machining a part, our team will immediately convene a meeting to resolve the issue.
We respond to abnormal situations within 30 minutes, provide solutions within 2 hours, and ensure that the problems are resolved within 24 hours.
Before CNC parts leave the factory, 100% dimensional inspection is conducted according to customer drawings. Inspection reports are provided before proceeding to the next processing step.
We offer anodizing, sandblasting, powder coating, etc., we also provide special surface treatments. All surface treated parts are subject to 100% visual inspection after returning to the workshop.
QC specialists inspect parts at each stage using tools like 3D/2D projectors, height gauges, thread and roughness testers. And we offer full dimensional inspection reports for parts.
We offer various packaging methods to prevent damage and ensure easy handling. Custom packaging is available, commonly using EPE foam and bubble wrap.
We are a 15-year-old custom CNC machining parts manufacturer with multiple certifications. These include ISO 9001:2015, IATF 16949:2015, and SGS on-site inspection reports.
Are derailleur hangers bike specific?
Yes, derailleur hangers are typically designed for specific bike frames and derailleur types. Proper fit ensures accurate alignment, smooth shifting, and reliable performance under riding conditions.
How do I provide specifications for my custom derailleur hanger?
Customers can submit CAD files, technical drawings, or detailed measurements. Contact VMT to discuss your project and receive a custom quote or solution, ensuring your derailleur hanger is manufactured exactly to your requirements.
How do you know what derailleur hanger you need?
Identify the correct hanger by checking your bike frame, derailleur type, and mounting style. You can also reference the original hanger or provide measurements and drawings to ensure the replacement is accurate and fits your bike perfectly.
Is there a Universal Derailleur Hanger?
