Do you sign NDAs to protect my proprietary robot designs?

Yes, protecting your intellectual property is our standard procedure. We are happy to sign your Non-Disclosure Agreement (NDA) before receiving any CAD files. All data is stored securely and access is strictly limited to the engineering team handling your project.

What machining tolerances can you achieve for complex structural parts?

We typically hold ISO 2768-m (medium) or f (fine) standards. For critical features like bearing bores or joint interfaces, we achieve tight tolerances of ±0.005mm. Every part is verified using CMM inspection to ensure strict adherence to your GD&T specifications.

How do you prevent deformation in large aluminum frames or chassis?

We utilize stress-relief annealing and specialized clamping strategies to minimize warping during material removal. For large thin-walled parts or long rails, we perform multiple machining passes with intermediate stress release to ensure flatness and dimensional stability.

What surface finishes do you offer for cosmetic robot housings?

We provide "cosmetic-grade" finishes for external parts. Options include bead blasting (Ra 1.6-3.2), anodizing (Type II/III in various colors), and powder coating or wet painting (Pantone/RAL matched) for a premium, consumer-ready look.

Do you provide mechanical assembly and hardware installation services?

Yes, we offer value-added assembly to streamline your production. We expertly install helical inserts, pins, and PEM fasteners. We also perform mechanical sub-assembly of structural frames and housings to verify fitment, ensuring you receive ready-to-integrate components.

Do you provide material test reports for verified structural integrity?

Yes, we provide full material traceability. Upon request, we supply Mill Test Reports (MTRs) for all structural metals (Aluminum 6061/7075, Steel, etc.), verifying chemical composition and mechanical properties to ensure your parts meet strict load-bearing requirements.

Do you offer DFM feedback to reduce weight or machining costs?

Absolutely. Before machining, our engineers review your CAD files to identify cost-drivers. We suggest optimizations—such as increasing corner radii or strategic pocketing for lightweighting—to help you balance structural rigidity with manufacturing efficiency and lower costs.
