OEM Trust & Factory Assurance

Stavalk is a bench vise manufacturer based in Jimo, Qingdao. We operate the 8,000 m² plant ourselves — sand casting, CNC machining, heat treatment, surface coating, assembly and testing happen in one facility. There are no trading-company handoffs: the people who answer your questions are the people who build your vises.

A named project engineer and a named QC contact, plus the department heads who sign your documents. You can ask to speak with the Chief Engineer, the QA Director or the factory director directly — before and after the order. No account-manager layer sits between you and the people doing the work.

Yes. We host factory visits in Jimo, Qingdao, and support remote audits with live video walkthroughs. Audits can be arranged independently (your inspector or a third party such as SGS, TUV, BV or Intertek) and the audit schedule can be written into the contract.

Yes. Our standard NDA is signed within 4 business hours of your request, before any proprietary specification, artwork or technical file is shared. Bilingual (English/Chinese) versions are available, and the document is countersigned by the factory director.

Every claim on this site has a document behind it: QMS SOPs and inspection standards are downloadable, anonymized quality-record samples are published, and test data is logged per batch with full ERP traceability. You can also schedule a third-party pre-shipment inspection at your choice.

Every vise is tested before packing, and batch-level records allow root-cause tracing per batch number. The contract defines inspection, replacement and rework obligations, and the QA Director signs the batch release. Reworked vises are re-tested in full — never partially checked.

Yes — and the records prove it. Every vise undergoes clamping force testing, jaw hardness verification (58–62 HRC), swivel torque checking, 10,000+ cycle durability testing and 48-hour salt-spray corrosion resistance testing. Test logs are linked to each batch and are part of the batch documentation.

ISO 9001:2015 quality management, ISO 14001 environmental management, CE compliance (EN ISO 12100, Machinery Directive 2006/42/EC) for bench vise products, plus RoHS compliance for the facility and materials. Certificate numbers and audit records are supplied on request or during an audit — the list is published, not "available on request only".

Yes. Your brand, designs and tooling are protected by NDA, brand licensing terms and mould/tooling ownership or buyout clauses written into the contract. Tooling is kept for the brand and transferable. Territory and exclusivity terms are agreed in writing before production starts.

MOQ is project-specific and explained on our MOQ guide: samples 1–2 units, co-branding small bulk 20+ units, pilot batches 20–50 units, and standard volume 50–200+ units per casting batch. Bespoke body castings run at the volume tier. The calculation is confirmed before quotation — no vague "low MOQ" numbers.

Lead time is confirmed after specification, branding and packaging review — never promised beforehand. The contract covers scheduling, delay notification and the resolution path, and the quarterly business review tracks delivery performance against the agreed calendar.

Orders and agreements are jointly signed by the Sales VP, the Chief Engineer and the QA Director — the three people accountable for commercial terms, engineering execution and quality release respectively. You receive the signed documents with the contract records.
