No—never. There are zero subscription fees, membership tiers, or platform service charges. Our 1-on-1 DFM (Design for Manufacturability) engineering review, process matching, and quotation services are 100% free. You only pay for the physical parts and tooling you approve for production.

We cut cost and lead time in three concrete ways: First, our engineers review your CAD within 24 hours to flag overly tight non-critical tolerances, deep pockets, or sharp internal corners that inflate CNC and tooling time—often reducing unit costs by 20%–35%. Second, we consolidate multi-process parts (casting, machining, anodizing, LSR molding) under one roof so you don't manage four separate vendors. Third, rapid bridge tooling delivers pilot batches in 7–10 days instead of waiting 4+ weeks for hard steel molds.

Quite the opposite. Automated Western quoting platforms and trading brokers typically add a 25% to 45% software and intermediary markup on top of the factory price. Because Purniss quotes directly from our own manufacturing lines and audited partner cells in China, you get transparent factory-direct pricing while still enjoying fluent English engineering support and strict export-grade quality control.

Every STEP, IGES, and PDF file uploaded through our RFQ portal is transmitted via 256-bit AES encryption into isolated, access-controlled cloud storage. Unlike open bidding boards where dozens of unknown shops download your drawings, your files are restricted strictly to your assigned project engineer and the specific production cell building your part. We gladly sign mutual NDAs (Non-Disclosure Agreements) before you upload a single file.

We take 100% single-point accountability for every shipment. Before any part leaves our facility, it undergoes dimensional verification on Coordinate Measuring Machines (CMM) alongside material certification (RoHS, mill certs, pressure/load tests where applicable). We send you visual milestone photos and the inspection report prior to dispatch. If any delivered component fails to meet the agreed drawing specifications, we re-manufacture and air-freight replacements at our expense or issue a full refund.

Yes—with 100% process lock. Every approved project is archived in our digital production vault with its exact CNC G-code, fixture setup, casting pattern, material heat batch, and CMM inspection program. When you re-order—whether 3 weeks or 18 months later—we route the job to the exact same production cell and tooling setup, ensuring batch-to-batch repeatability without re-qualifying.

Every single quote includes a complimentary pre-order DFM review. Before you pay a cent or place a purchase order, our senior manufacturing engineers inspect your 3D model and 2D drawing. We provide marked-up feedback on wall thickness, draft angles, undercut risks, tolerance stack-ups, and surface finishing compatibility—so you can finalize your design with complete confidence.

If you need an Engineering Change Order (ECO) after production starts, message your dedicated project engineer immediately—because we control the shop floor directly, we can pause the machine, evaluate the revision impact, and update toolpaths with minimal downtime. If a delivered part ever deviates from your approved drawing due to our error, our Zero-Risk Guarantee kicks in: we log a root-cause 8D report within 24 hours and expedite replacement parts via DHL Express free of charge.
