Why Choose Conwhole for OEM Manufacturing Support?
Direct Factory Ownership & Control
We are a direct manufacturing factory, not a trading middleman. You gain direct pricing transparency, real-time engineering feedback, and strict control over quality and delivery schedules.
Bilingual Engineering & Seamless Comms
Our sales engineers are fluent in technical English and 3D CAD modeling. We eliminate miscommunications, respond within 12 hours, and ensure your drawing specs are translated perfectly to the shop floor.
Uncompromising IP Protection
We protect your commercial advantage with legally binding NDAs, strict CAD file encryption, and private-label packaging to keep your proprietary designs completely confidential.
Quality Compliance & Full Audits
Our production facility follows a documented quality management system. We welcome third-party factory audits (SGS, TÜV, Bureau Veritas) and supply complete material MTRs, CMM reports, and PPAP packages.
Q1: Will Conwhole sign a Non-Disclosure Agreement (NDA) before I share my engineering drawings?
Yes, absolutely. We routine execute bilateral NDAs with our international clients prior to receiving any proprietary CAD drawings or technical specifications.
Q2: Can we send a third-party inspection agency (e.g., SGS, TÜV) to audit the factory?
Yes. We welcome third-party factory quality audits and pre-shipment product inspections. We regularly cooperate with SGS, TÜV, Bureau Veritas, and client-appointed quality inspectors.
Q3: What documentation do you supply with initial OEM prototype samples?
With initial prototype samples, we supply a First Article Inspection (FAI) dimensional report, CMM measurement logs, material mill test reports (MTR / EN 10204 3.1), and surface coating thickness test records.
Q4: How do you handle engineering design changes (ECO) after mass production has started?
We operate a formal Engineering Change Order (ECO) protocol. When drawing revisions occur, our team immediately updates shop floor CAD files, re-verifies CNC programming, archives legacy tooling, and issues a formal ECO sign-off before restarting production.
Q5: Can you provide private-label branding and custom export packaging for OEM parts?
Yes. We offer custom laser marking for logos and part numbers, custom inner foam packaging, private-label cartons, custom barcode shipping labels, and VCI rust-inhibitor wrapping for export sea freight.
Q6: What are your standard trade and shipping terms for international OEM clients?
We support FOB Ningbo/Shanghai, CIF, CFR, and DDP (Delivered Duty Paid). Under DDP terms, we handle customs clearance, import duties, and local trucking directly to your factory doorstep.
Q7: How do you manage raw material price fluctuations on long-term OEM contracts?
For annual OEM supply contracts, we offer locked-price agreements based on quarterly raw metal index benchmarks, or maintain safety stock raw material inventory in our warehouse to absorb short-term market spikes.
Q8: What is the typical lead time for OEM prototype samples and mass production?
Prototype samples are typically delivered in 7 to 10 business days depending on complexity. First mass production batches take 3 to 4 weeks after sample sign-off, with repeat batch orders running on a 2-week cycle.
